Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

This driver uses semantic versioning:

A change in the bugfix version (e.g. X.Y.0 -> X.Y.1) indicates internal changes and should always be safe to upgrade.
A change in the minor version (e.g. X.1.Z -> X.2.0) indicates additions and backwards-compatible changes that should not affect your code.
A change in the major version (e.g. 1.Y.Z -> 2.0.0) indicates breaking changes that require changes in your code to upgrade.

9.2.0 - 2024-11-27

Added

Added database.availability method
Added database.engine method (DE-931)
Added database.status method (#811)
Added database.supportInfo method
Added keepNull option to CollectionInsertOptions type (DE-946)

This option was previously missing from the type.
Added allowDirtyRead option to DocumentExistsOptions type (DE-945)

This option was previously missing from the type.
Added ignoreRevs option to CollectionBatchReadOptions type (DE-947)

This option was previously missing from the type.
Added options argument to CollectionTruncateOptions type (DE-940)

There was previously no way to pass options to the truncate method.
Added database property to Analyzer, ArrayCursor, BatchedArrayCursor, Collection, Graph, Job, Route, Transaction and View (DE-935)

This property can be used to access the database instance a given object belongs to.
Added Route#headers and Route#path properties

These properties can be used to access the headers and path used when creating the route.
Added ArrayCursor#id and BatchedArrayCursor#id properties (DE-936)

This property can be used to access the ID of the cursor.

9.1.0 - 2024-09-25

Changed

Removed progress property from Index type

This property is only available when fetching indexes with the withHidden option set to true.
Added HiddenIndex type (DE-849)

This type is used to represent an index returned by collection.indexes when the withHidden option is set to true and includes the progress property in addition to internal indexes.

9.0.0 - 2024-07-31

This is a major release and breaks backwards compatibility.

See the migration guide for detailed instructions for upgrading your code to arangojs v9.

Removed

Removed Node.js 14 and Node.js 16 support

With Node.js 14 and 16 having reached their end of life, arangojs will no longer support these versions of Node.js going forward.

For more information, see the Node.js release schedule.
Removed Params and Headers types

These can mostly be replaced with the native URLSearchParams and Headers types but most public methods still accept the equivalent Record types for convenience.
Removed deprecated FulltextIndex and related types

Fulltext indexes have been deprecated in ArangoDB 3.10 and should be replaced with ArangoSearch.
Removed browser build

The browser build has been removed from the repository and will no longer be published to npm. The npm package can still be used in the browser by using common frontend tooling like webpack or rollup.
Removed Collection methods for simple queries: list, all, any, byExample, firstExample, removeByExample, replaceByExample, updateByExample, lookupByKeys, removeByKeys, fulltext

Simple queries were deprecated in ArangoDB 3.4 and can be replicated with AQL.

Changed

Replaced request logic with native fetch API (#788, DE-578, DE-758)

The node-specific request logic using the http and https modules has been replaced with all-new logic using the web standard fetch API, which should work in Node.js, browsers and other conformant environments.
Unicode names are now no longer automatically NFC normalized (DE-65)

This change affects all database, collection, graph, view and analyzer names using unicode characters. Starting with arangojs v7.7.0 these names were automatically NFC normalized. This behavior has now been reverted to match the behavior of other ArangoDB drivers and help detect normalization issues in user code.
Changed return type of aql and the AQL join helper function to AqlQuery

Previously the internal GeneratedAqlQuery type was exposed as the return type of these functions, leading to complexity when handling generic type arguments.
Removed dependency on Node path module or its browserify equivalent

This change should be backwards-compatible but may produce different results when using non-normalized paths and base-paths in custom routes. This should help support more environments and reduce the size of the browser bundle.
Inlined x3-linkedlist dependency

Inlining this dependency should help make arangojs more portable.
Split the Collection type parameter into result and input types (#807)

It is now possible to specify a separate type for the data passed when creating or modifying documents in addition to the type of the data returned when fetching documents. This allows excluding computed properties from the input type while still including them in the result type.

Added

Added ESM support (DE-236)

The driver now supports being imported as an ES module or CommonJS module and provides exports for both types of environments. This change should be backwards-compatible.
Added support for withHidden option in collection.indexes

This option was introduced in ArangoDB 3.10.13 and 3.11.7 and allows fetching the progress information of indexes that are in the building phase.
Added support for withStats option in collection.indexes

This method now takes an object with withStats and withHidden options instead of a boolean flag.
Added readonly Job#id property

This property was not previously exposed.
Added skipFastLockRound option for streaming transactions

This option was introduced in 3.12.1 and allows skipping the fast lock round.
Added non-specific EnsureIndexOptions type and ensureIndex method signature (#778)

This allows creating indexes without narrowing the index type.

8.8.1 - 2024-03-20

Added

Added the versionAttribute option to the document operation options types (DE-783)

8.8.0 - 2024-03-12

Changed

Renamed ZKD index type to MDI (DE-744)

The ZKD index type was previously marked as experimental and has now been finalized and renamed to MDI in ArangoDB 3.12.
Added DocumentOperationMetadata and DocumentOperationFailure types (DE-693)

The return types of document and edge operations on collections have been modified to correctly represent the return values of bulk operations and single document/edge operations using the overwriteMode option.

Deprecated

Deprecated active failover support (DE-746)

Active failover is no longer be supported in ArangoDB 3.12 and later. This functionality will be removed from the driver in a future release.

Added

Added support for multi_delimiter analyzer type (DE-753)
Added support for wildcard analyzer type (DE-750)

8.7.0 - 2024-02-14

Changed

Made options argument in collection.edges, inEdges and outEdges optional (#802)

Deprecated

Deprecated db.getLogMessages

This API was deprecated in ArangoDB 3.8 and should no longer be used. Use db.getLogEntries instead.

Fixed

Fixed db.getLogEntries using the wrong API endpoint

8.6.0 - 2023-10-24

Added

Added db.createJob method to convert arbitrary requests into async jobs (DE-610)

This method can be used to set the x-arango-async: store header on any request, which will cause the server to store the request in an async job:

const collectionsJob = await db.createJob(() => db.collections());
// once loaded, collectionsJob.result will be an array of Collection instances
const numbersJob = await db.createJob(() =>
  db.query(aql`FOR i IN 1..1000 RETURN i`)
);
// once loaded, numbersJob.result will be an ArrayCursor of numbers

8.5.0 - 2023-10-09

Added

Implemented hot backup API (DE-576)
Implemented logging API (DE-144, DE-145, DE-146, DE-147)
Implemented async jobs management (DE-339)
Added db.shutdown to initiate a clean shutdown of the server
Added db.time method to retrieve the server's system time

8.4.1 - 2023-09-15

Fixed

Fixed default return type of AQL queries being undefined instead of any (#797)

8.4.0 - 2023-07-10

Changed

Fetching additional cursor results now uses POST instead of PUT (DE-605)

The PUT route was deprecated and the POST route is supported in all actively maintained versions of ArangoDB.
User management methods now use database-relative URLs (DE-606)

Previously these methods would make requests without a database prefix, implicitly using the _system database.
aql template strings now take a generic type argument

This allows explictly setting the item type of the ArrayCursor returned by db.query when using aql template strings. Note that like when setting the type on db.query directly, arangojs can make no guarantees that the type matches the actual data returned by the query.
```
const numbers = await db.query(aql<{ index: number; squared: number }>`
  FOR i IN 1..1000
  RETURN {
    index: i,
    squared: i * i
  }
`);
const first = await numbers.next(); // { index: number; squared: number; }
console.log(first.index, first.squared); // 1 1
```

Fixed

Fixed listUsers behavior (#782)
Fixed graph.create not correctly handling isDisjoint option

Added

Added missing attributes to QueryInfo and MultiExplainResult.stats types (DE-607)
Added cluster rebalancing methods to Database (DE-583)

Added db.withTransaction helper method for streaming transactions (#786)

This method allows using streaming transactions without having to manually begin and commit or abort the transaction.

const vertices = db.collection("vertices");
const edges = db.collection("edges");
const info = await db.withTransaction([vertices, edges], async (step) => {
  const start = await step(() => vertices.document("a"));
  const end = await step(() => vertices.document("b"));
  return await step(() => edges.save({ _from: start._id, _to: end._id }));
});

8.3.1 - 2023-06-05

Changed

Added note that Simple Queries traversals are removed in ArangoDB 3.12.

8.3.0 - 2023-05-11

Fixed

Fixed updateUser and replaceUser behavior (#783)

Added

Added renewAuthToken method to Database (#784)

This method allows refreshing the authentication token passed to the useBearerAuth method or used by the login method. Note that ArangoDB will currently only return a new token if the token is going to expire in the next 150 seconds.
Added returnOld and mergeObjects to CollectionInsertOptions type

These options are only available when using overwriteMode.
Added caching options to InvertedIndex and ArangoSearchView types

These options were added in ArangoDB 3.10.2.
Added support for ArangoSearchView type storedValues shorthand notation

Instead of using an object, attributes can also be defined as arrays of strings and arrays of arrays of strings. This was added in ArangoDB 3.10.3.
Added peakMemoryUsage and executionTime to SingleExplainResult.stats type

These attributes were added in ArangoDB 3.10.4.
Added geo_s2 Analyzer types

This Analyzer was added in ArangoDB 3.10.5.
Added refillIndexCaches option to document operation options types

This option was added in ArangoDB 3.11.
Added optimizeTopK to ArangoSearchView and InvertedIndex types

This option was added in ArangoDB 3.11.
Added support for allowRetry option in db.query

This feature was added in ArangoDB 3.11.
Added x-arango-driver header

The arangojs driver now correctly identifies itself to ArangoDB, allowing the ArangoGraph Insights Platform to take advantage of the driver's support for cloud-optimized behaviors.

8.2.1 - 2023-04-05

Fixed

Fixed a bug in search parameter handling in the browser version

Previously the browser version would incorrectly handle search parameters, which could result in invalid request URLs in many cases.

8.2.0 - 2023-03-29

Changed

Index names are now automatically NFC-normalized (DE-506)

This change affects all index names using unicode characters. The change has no effect when using non-unicode (ASCII) names.

Any names used when creating/ensuring indexes or passed to any methods that expect an IndexSelector will automatically be NFC normalized.
Internal querystring handling logic now uses URLSearchParams instead of node querystring module

This change should be backwards compatible but may produce different results when relying on undefined behavior in custom (e.g. Foxx) routes.

8.1.0 - 2022-12-19

Added

Added support for new ArangoDB 3.9.5 cache field in ArangoSearch types

8.0.0 - 2022-10-25

This is a major release and breaks backwards compatibility.

See the migration guide for detailed instructions for upgrading your code to arangojs v8.

Removed

Removed Node.js 10 and Node.js 12 support

With Node.js 10 and 12 having reached their end of life, arangojs will no longer support these versions of Node.js going forward.
Removed Internet Explorer and older browser support

As of version 8 arangojs uses the Browserlist defaults list to generate the pre-built browser bundle, which excludes older browsers and specifically all versions of Internet Explorer.

You may still be able to use arangojs in some of the excluded browsers when bundling arangojs yourself but this may require polyfills and additional transformations.
Removed Dict type from connection module

The Dict<T> type was identical to Record<string, T> and has been replaced with this built-in type across arangojs.
Removed workaround for ArangoDB pre-3.2.8 Foxx HTTP API responses

When fetching or modifying the configuration or dependencies of a Foxx service using ArangoDB 3.2.7 and earlier, arangojs would perform additional operations to convert the server response to a compatible format. All affected versions of ArangoDB have reached End of Life since December 2018.
Removed deprecated db.useDatabase method

The method was previously deprecated and can be replaced with db.database, which returns a new Database object instead of modifying the existing one.
Removed deprecated MMFiles methods and types

The MMFiles storage engine was removed in ArangoDB 3.7.
Removed deprecated minReplicationFactor option from collection and database related types

This option was renamed to writeConcern in ArangoDB 3.6.
Removed deprecated overwrite option from CollectionInsertOptions type

This option was deprecated in ArangoDB 3.7 and should be replaced with the overwriteMode option.
Removed internal request.host attribute

This attribute has been replaced with request.hostUrl.
Removed internal response.arangojsHostId attribute

This attribute has been replaced with response.arangojsHostUrl.
Removed CollectionStatus and CollectionType enum re-exports

Previously these would be re-exported by the arangojs module for backwards compatibility. If you still need to access these enums, you can import them from the collection sub-module instead. Note that the ViewType enum has been removed completely.

Changed

Changed default URL to http://127.0.0.1:8529 to match ArangoDB default

Previously arangojs would use localhost which on some systems resolves to the IPv6 address ::1 instead, resulting in confusing connection errors.
Changed TypeScript compilation target to ES2020

Since all evergreen browsers including Firefox ESR and all active Node.js LTS releases fully support ES2020, the compilation target for the browser bundle and Node.js has been moved from ES2016 and ES2018 respectively to ES2020.
Updated TypeScript to version 4.8

This may result in type signatures that are incompatible with TypeScript 3 being added in future releases (including patch releases).
Changed default behavior of internal db.request method

Previously this method would always return the full response object if no transform callback was provided. The method now defaults to a transform callback that extracts the response body instead. The previous behavior can still be forced by passing false instead of a callback function.

This change has no effect on other methods like route.request.
Replaced node core module polyfills with native APIs in browser build

As part of upgrading to webpack 5, arangojs now no longer requires node core modules to be polyfilled to work in the browser. This also drastically reduces the file size of the pre-built browser bundle arangojs/web.

db.query now supports a generic return type (#764)

This allows explictly setting the item type of the ArrayCursor returned by the query without using a type assertion on the promise result. Note that arangojs can make no guarantees that the type matches the actual data returned by the query.

const numbers = await db.query<{ index: number; squared: number }>(aql`
  FOR i IN 1..1000
  RETURN {
    index: i,
    squared: i * i
  }
`);
const first = await numbers.next(); // { index: number; squared: number; }
console.log(first.index, first.squared); // 1 1

Moved aql.literal and aql.join into aql module

Previously these were available as methods on the aql function. Now they need to be imported from the aql module.
Changed return values of db.getUserAccessLevel and db.getUserDatabases to match documented return types
Retry requests resulting in status 503 ArangoError (#710)

Unless retries are explicitly disabled by setting config.maxRetries to false, requests will now also be retried if the server responded with a 503 ArangoError, which ArangoDB uses to indicate the server is running in maintenance mode. Previously this would always result in an error.
Extended CursorExtras type in TypeScript

The types of the attributes plan, profile, and stats are now defined more explicitly.
Changed behavior of collection.removeAll for non-string arrays

Previously collection.removeAll would always convert its argument into an array of document IDs and fail with an error if passed any documents had an ID not matching the collection name. Now the selector argument is passed as-is, bypassing this validation but allowing ignoreRevs to be respected by the server.
Extracted type ArangoSearchViewLinkOptions from ArangoSearchViewLink

Note that ArangoSearchViewLink now represents the type of the value returned by the server, marking several properties as required.
Extracted type CreateArangoSearchView from ArangoSearchViewPropertiesOptions

Note that ArangoSearchViewPropertiesOptions now includes only those options that can be updated/replaced whereas CreateArangoSearchView also includes options that can only be set during creation of a view.
Renamed type GraphCreateOptions to CreateGraphOptions
Renamed type PrimarySortCompression to Compression
Replaced type AnalyzerInfo and all its constituent types

Previously each type of Analyzer was represented by an AnalyzerInfo type and (where relevant) an AnalyzerProperties type, which were used for both creating and fetching Analyzers. The new types more closely follow the pattern already used for index types, providing pairs of CreateAnalyzerOptions and AnalyzerDescription types.
Removed enum ViewType, type ArangoSearchView and changed View class to be non-generic

The View class now behaves analogous to the Analyzer class. The various types related to different view types have been restructured to more closely follow the pattern used for indexes and analyzers.

Deprecated

Deprecated EnsureFulltextIndexOptions and FulltextIndex types

Fulltext indexes have been deprecated in ArangoDB 3.10 and should be replaced with ArangoSearch.
Deprecated BytesAccumConsolidationPolicy type

The bytes_accum consolidation policy for views was deprecated in ArangoDB 3.7 and should be replaced with the tier consolidation policy. The type is also no longer supported in ArangoSearchViewPropertiesOptions.

Added

Added toJSON method to system errors

ArangoJS already adds the request object to system errors encountered while attempting to make network requests. This change makes it easier to serialize these error objects to JSON the same way ArangoError and HttpError objects can already be serialized.
Added allowDirtyRead option to db.beginTransaction, trx.commit, trx.abort, collection.edges, collection.inEdges, collection.outEdges

The option is only respected by read-only requests.
Added support for ifMatch and ifNoneMatch options (#707)
Added overwrite option to db.acquireHostList (#711)

Setting this option to true will replace the current host list, removing any hosts no longer present in the cluster.
Added new ArangoDB 3.10 legacyPolygons option to EnsureGeoIndexOptions and GeoIndex types

Geo indexes created in ArangoDB pre-3.10 will implicitly default this option to true. ArangoDB 3.10 and later will default to false and use the new parsing rules for geo indexes.
Added support for new ArangoDB 3.10 cacheEnabled and storedValues options in persistent indexes
Added support for new ArangoDB 3.10 computed values in collections
Added support for new ArangoDB 3.10 InvertedIndex type
Added support for new ArangoDB 3.10 offset Analyzer feature
Added support for new ArangoDB 3.10 minhash, classification and nearest_neighbors Analyzer types
Added missing replicationFactor and writeConcern options to CollectionPropertiesOptions type
Added missing commitIntervalMsec option to ArangoSearchViewProperties type
Added missing deduplicate option to EnsurePersistentIndexOptions type (#771)
Added missing unique option to EnsureZkdIndexOptions type
Added missing deduplicate and estimates fields to PersistentIndex type
Added new ArangoDB 3.10 db.queryRules method
Added support for Analyzer in aql templates

Analyzer objects can now be passed into aql templates like View and ArangoCollection objects.
Added retryOnConflict option to Config

If set to any number, this value will be used as the default value for all requests unless explicitly overridden when using db.query or route.request.

7.8.0 - 2022-05-19

Added

Added retryOnConflict option to db.query and route.request

This option allows specifying the number of times the request will be retried if it results in a write-write conflict.

7.7.0 - 2022-01-26

Changed

Unicode names are now automatically NFC normalized

This change affects all database, collection, graph, view and analyzer names using unicode characters. The change has no effect when using non-unicode (ASCII) names. At this time, ArangoDB does not support unicode characters in any of these names but experimental support for unicode database names is available in ArangoDB 3.9 using the --database.extended-names-databases startup option.

Any names used to create Database, Collection, etc instances or passed to methods will automatically be NFC normalized. Additionally the collection name part of any value passed as a DocumentSelector and the collection name part of values returned by collection.documentId will automatically be NFC normalized.

Deprecated

Deprecated EnsureHashIndexOptions and EnsureSkiplistIndexOptions types

The hash and skiplist index types have been deprecated in ArangoDB 3.9 and should be replaced with persistent indexes which behave identically.
Deprecated all MMFiles related options and methods

The MMFiles storage engine was removed in ArangoDB 3.7.

Added

Added support for new ArangoDB 3.9 CollationAnalyzer and SegmentationAnalyzer types
Added support for new ArangoDB 3.9 (multi-dimensional) ZkdIndex type
Added support for new ArangoDB 3.9 Hybrid SmartGraphs graph options
Added support for new ArangoDB 3.9 response queue time reporting

This adds the db.queueTime property, which provides methods for accessing queue time metrics reported by the most recently received server responses if the server supports this feature.
Added ArangoSearchViewLink#inBackground (#759)
Added collection.compact (#630)

7.6.1 - 2021-10-26

Fixed

Changed all uses of Record<string, unknown> to Record<string, any> (#750)

This should allow using more specific types without having to implement index signatures.

7.6.0 - 2021-10-20

Added

Added collection.documents for fetching multiple documents
Added support for fillBlockCache query option
Added support for passing Graph objects in AQL queries (#740)

This also adds the isArangoGraph helper function for type checking.
Added User Management API (#664)

This implements the endpoints of the HTTP Interface for User Management

Fixed

Added missing hex option to StopwordsAnalyzer type (#732)
Added missing details option to collection.figures (#728)
Added missing inBackground option to index options (#734)

7.5.0 - 2021-04-22

Added

Added support for new ArangoDB 3.8 Analyzer types

This adds the PipelineAnalyzer, AqlAnalyzer, GeoJsonAnalyzer, GeoPointAnalyzer and StopwordsAnalyzer types in TypeScript, as well as the Analyzer-specific properties types.
Added support for new ArangoDB 3.8 estimates option for indexes

This affects the PersistentIndex, HashIndex and SkiplistIndex types in TypeScript.

7.4.0 - 2021-04-09

Added

Implemented toJSON methods for ArangoError and HttpError (#632)

This prevents an error where JSON.stringify would reliably throw if passed an instance of either of these error types generated by arangojs. Note that you may still want to implement your own JSON representation logic as system errors (e.g. ECONNREFUSED) are not wrapped by arangojs and thrown as-is.

Fixed

Stack traces are now improved for most errors when using precaptureStackTraces (#722)

Previously this option would only affect network errors, making it far less useful than intended. Now parsing errors, ArangoError instances and HTTP errors also receive improved error stack traces when this option is enabled.
Improved performance for precaptureStackTraces when no errors occur

The generated stack is now only accessed on demand, allowing the runtime to delay generation of the stack trace string. Previously the stack would always be accessed prior to the request being sent, causing a noticeable delay even when no error occurs.
Fixed document selector validation in collection.edges and its variants (#704)

These methods previously only permitted start vertices that are documents within the edge collection itself. This behavior has now been corrected to permit start vertices outside the collection, as expected.

7.3.0 - 2021-03-08

Changed

Changed the default for agentOptions.scheduling to "lifo"

This is already the default in Node v15.6 but can reduce latency caused by sockets expiring, especially with larger connection pools and infrequent requests.
Removed keepAlive-specific throughput optimization

Previously arangojs would allow agentOptions.maxSockets * 2 concurrent requests, to optimize socket reuse by avoiding idle time. This behavior could trigger deadlocks when attempting to perform multiple transactions in parallel and only marginally improved throughput in some high-load scenarios. The connection pool size now always reflects the value set in agentOptions.maxSockets regardless of whether keepAlive is enabled.
Changed agentOptions.maxSockets default value when using ROUND_ROBIN

As the connection pool is shared across all server connections when using ROUND_ROBIN load balancing, the default value of 3 is too limiting for most scenarios involving multiple coordinators. When passing multiple URLs via the url option and specifying ROUND_ROBIN load balancing, arangojs will now default this value to url.length * 3 instead.

7.2.0 - 2020-12-02

Added

Added db.waitForPropagation method

This method helps with setting up databases in a cluster scenario by waiting for a request to succeed on every known coordinator.

7.1.1 - 2020-11-30

This is a maintenance release and contains no bugfixes or features.

7.1.0 - 2020-10-16

Changed

Killing a cursor now also drains it locally

Fixed

Fixed a potential memory leak in cursor batch handling

7.0.2 - 2020-09-25

Fixed

Fixed incorrect HTTP method call in patch method (#687)
Fixed empty query results containing [undefined] (#683)
Fixed updateByExample and replaceByExample new value parameter name

Note that these methods are still deprecated. Previously the newValue parameter was incorrectly called newData, which prevented the methods from working at all.

7.0.1 - 2020-08-21

This is a maintenance release because the initial v7 release did not include a README file.

7.0.0 - 2020-08-21

This is a major release and breaks backwards compatibility.

See the migration guide for detailed instructions for upgrading your code to arangojs v7.

For a detailed list of changes between pre-release versions of v7 see the Changelog of the final v7 release candidate.

Removed

General

Removed ArangoDB 2.8 support

ArangoDB 2.8 has reached End of Life since mid 2018. Version 7 and above of arangojs will no longer support ArangoDB 2.8 and earlier.
Removed Node.js 6/8 support

As of version 7 arangojs now requires language support for async/await. This means arangojs requires Node.js 10 (LTS) or newer to function correctly.
Removed support for absolute endpoint URLs

This removes the isAbsolute option from the arangojs configuration.
Removed ArangoError re-export

The type can still be imported directly from the error module.
Removed statusCode properties of ArangoError and HttpError

Both of these error types still expose the HTTP status code as the code property. For ArangoError the true HTTP status code may be different and can still be accessed using the response.statusCode property.

Database API

Removed db.edgeCollection method

As arangojs 7 uses the same implementation for document and edge collections, this method is no longer necessary. Generic collection objects can still be cast to DocumentCollection or EdgeCollection types in TypeScript.
Removed db.truncate convenience method

This was a wrapper around db.listCollections and collection.truncate. The behavior of db.truncate can still be emulated by calling these methods directly.

Collection API

Removed collection createCapConstraint, createHashIndex, createSkipList, createPersistentIndex, createGeoIndex and createFulltextIndex methods

These methods are no longer part of the official ArangoDB API and can be replaced by using the collection.ensureIndex method.
Removed save(fromId, toId, edgeData) method variants

Methods for creating edges now require the _to and _from attributes to be specified in the edge (document) data and no longer accept these values as positional arguments.
Removed collection.bulkUpdate method

The new method collection.updateAll now provides this functionality.
Removed collection.edge method

This method was previously an alias for collection.document.

The method graphEdgeCollection.edge is unaffected by this change.
Removed graphName option for edgeCollection.traversal

Graph traversals can still be performed via graph.traversal.

Graph API

Removed generic collection methods from GraphVertexCollection

All methods that are not part of the graph API have been removed. The underlying collection can still be accessed from the collection property.
Removed generic collection methods from GraphEdgeCollection

All methods that are not part of the graph API have been removed. The underlying collection can still be accessed from the collection property.

Cursor API

Removed cursor.some and cursor.every methods

These methods encouraged overfetching and should be replaced with more efficient AQL queries.

The behavior can still be implemented by using the next method directly or iterating over the cursor using the forEach method or the for await syntax.

View API

Removed ViewResponse type

The type ViewDescription represents the same structure.
Removed ArangoSearchViewPropertiesResponse type

The type ArangoSearchViewProperties & ViewDescription can be used to represent the same structure.

Deprecated

Database API

Deprecated db.useDatabase method

Using this method will affect Collection, Graph and other objects already created for the given database and change which database these refer to, which may cause unexpected behavior.

As of arangojs 7 the db.database method can be used instead to create a new, separate Database object using the same connection pool.

Collection API

Deprecated Collection methods for simple queries: list, all, any, byExample, firstExample, removeByExample, replaceByExample, updateByExample, lookupByKeys, removeByKeys, fulltext

These methods were deprecated in ArangoDB 3.4 and should no longer be used. They will still behave correctly with versions of ArangoDB supporting these methods but may be removed in a future ArangoDB release.

Their behavior can be emulated using AQL queries.

Graph API

Deprecated graph.traversal and collection.traversal

These methods were deprecated in ArangoDB 3.4 and should no longer be used. They will still behave correctly with versions of ArangoDB supporting these methods but may be removed in a future ArangoDB release.

Their behavior can be emulated using AQL graph traversal.

Changed

General

Multiple Database objects can now share a single Connection

All arangojs objects now reference a Database object rather than accessing the underlying Connection directly. This allows multiple Database objects to be created by using the db.database method while still allowing the creation of separate database objects with separate connection pools if desired.
Memoized Database, Collection, Graph, View and Analyzer

Database objects are now memoized per-connection and the other object types are memoized per-database. Using useDatabase de-memoizes the database object to prevent unexpected behavior.
Added support for View in aql templates (#667)

View (or ArangoSearchView) objects can now be passed into aql templates like ArangoCollection objects.
Moved collectionToString helper into collection module
Moved Dict type into connection module
Moved Patch type into documents module
Removed Errback type from public API
Renamed util/foxx-manifest module to foxx-manifest

Database API

Renamed method db.arangoSearchView to db.view
Renamed method db.createArangoSearchView to db.createView
Replaced methods db.enableServiceDevelopmentMode and db.disableServiceDevelopmentMode with db.setServiceDevelopmentMode
Flattened database query method options argument

The optional options argument previously contained an additional options object with additional query options. These options are now specified on the options argument itself directly.

Before:
```
db.query(aql`FOR doc IN ${collection} RETURN doc`, {
  cache: false,
  options: { fullCount: true },
});
```
After:
```
db.query(aql`FOR doc IN ${collection} RETURN doc`, {
  cache: false,
  fullCount: true,
});
```
Changed db.listServices option excludeSystem default to true

To be more consistent with the equivalent options in other methods, the default value has been changed from false to true.
Changed db.createDatabase return type to Database
Renamed database.setQueryTracking to database.queryTracking

The method will now return the existing query tracking properties or set the new query tracking properties depending on whether an argument is provided.
Method db.transaction no longer acts as an alias for executeTransaction

The method now only allows looking up transactions by ID. Previously it would wrap executeTransaction if passed the arguments expected by that method.

Collection API

Merged DocumentCollection and EdgeCollection APIs

All collections are now implemented as generic Collection objects. In TypeScript the generic collection object can still be explicitly cast to DocumentCollection or EdgeCollection for stricter type safety.
Renamed collection.setProperties to collection.properties

The method will now return the existing properties or set the properties depending on whether an argument is provided.
Removed CollectionMetadata fields from CollectionProperties type

Methods that previously returned CollectionProperties now return CollectionMetadata & CollectionProperties.
Collection methods save, update, replace and remove no longer take arrays as input

The array versions have been renamed to saveAll, updateAll, replaceAll and removeAll to reduce the likelihood of mistakes and provide more helpful type signatures.
Collection methods will now throw errors when passed documents or document IDs from different collections where a document key or ID for a document in the same collection is expected

For example the following code will now result in an error rather than the document from a different collection being returned:
```
const aliceId = "alice/123"; // Document from collection "alice"
const bobCol = db.collection("bob"); // Collection "bob"
const doc = await bobCol.document(aliceId); // THROWS
```
Changed collection.import option type behavior

Previously this option would always default to "auto".

When passing a string, Buffer or Blob as data, the option now defaults to undefined. This matches the behavior in previous versions of setting the option explicitly to null.

Additionally, the value "array" has been replaced with "list".

When passing an array as data, the option is now no longer supported as the corresponding value will be inferred from the array's contents:

If the array's first item is also an array, it will match the behavior in previous versions of setting the option explicitly to null.

Otherwise it will match the behavior in previous versions of setting the option explicitly to "documents" or "auto", or omitting it entirely.
Changed collection.list return type to ArrayCursor

Graph API

Graph methods now also accept ArangoCollection instances instead of names

This brings these methods behavior in line with that of the beginTransaction and executeTransaction methods of Database objects.

Graph create method (and db.createGraph) signature changed

The graph.create method now takes an array of edge definitions as the first argument and any additional options (not just the waitForSync option) as the second argument.

Before:

await graph.create(
  {
    edgeDefinitions: [{ collection: "edges", from: ["a"], to: ["b"] }],
    isSmart: true,
  },
  { waitForSync: true }
);

After:

await graph.create([{ collection: "edges", from: ["a"], to: ["b"] }], {
  isSmart: true,
  waitForSync: true,
});

First argument to graph.replaceEdgeDefinition is now optional

Since the new edge definition already includes the edge collection name that identifies the edge definition, it is now possible to specify only the new edge definition object without additionally specifying the collection name as the first argument.

Before:
```
await graph.replaceEdgeDefinition("edges", {
  collection: "edges", // This is a bit redundant
  from: ["a"],
  to: ["b"],
});
```
After:
```
await graph.replaceEdgeDefinition({
  collection: "edges",
  from: ["a"],
  to: ["b"],
});
```
Graph collection return values now contain old and new properties when returnOld or returnNew options are used

This behavior represents a compromise between remaining consistent with the behavior of the regular collection method equivalents and remaining compatible with the ArangoDB HTTP API response object quirks.

Cursor API

Replaced ArrayCursor methods hasNext and hasMore with getters
Renamed ArrayCursor method each to forEach
Renamed cursor.nextBatch to cursor.batches.next
Renamed cursor.hasMore to cursor.batches.hasMore
In TypeScript ArrayCursor is now a generic type

TypeScript users can now cast cursor instances to use a specific type for its values rather than any to aid type safety.

View API

Renamed view.setProperties to view.updateProperties
Renamed type ArangoView to View

Analyzer API

Renamed type ArangoAnalyzer to Analyzer

Transaction API

Renamed type ArangoTransaction to Transaction
Renamed transaction.run to transaction.step

This should hopefully make it more obvious that sequential calls to arangojs methods should be split into separate calls of this method.

Added

General

Added databaseName configuration option

Setting this option to a database name will result in the initial Database object using this database instead of the default _system database.
Added auth configuration option

It is now possible to pass authentication credentials using the auth option in addition to calling db.useBasicAuth or db.useBearerAuth.
Added precaptureStackTraces configuration option (#599)

This option can be used to get more useful stack traces but results in a performance hit on every request.
Added before and after to the agentOptions configuration option (#585)

These methods can be used to track performance metrics for outgoing requests.
Improved type signatures for TypeScript and inline documentation

Most methods should now provide full type signatures for options and response objects and provide inline documentation in IDEs and editors that support this feature in TypeScript and JavaScript.

Database API

Added db.database method

This method replaces the use case for the deprecated db.useDatabase method.
Added support for extended options in db.createDatabase

This method now supports passing an extended options object instead of passing the users array directly.
Added db.createCollection and db.createEdgeCollection methods

These are convenience methods wrapping collection.create. In TypeScript createEdgeCollection will return a collection cast to the EdgeCollection type.
Added db.createGraph method

This is a convenience method wrapping graph.create.
Added db.createArangoSearchView method

This is a convenience method wrapping view.create.
Added db.createAnalyzer method

This is a convenience method wrapping analyzer.create.
Added support for db.createFunction option isDeterministic
Added support for db.listServices option excludeSystem

Collection API

Added collection saveAll, updateAll, replaceAll and removeAll methods

These methods replace the respective array versions of the collection methods save, update, replace and remove, which no longer accept arrays as inputs.
Added collection.documentId method

The method takes a document or a document key and returns a fully qualified document ID string for the document in the current collection.
Added support for values "ignore" and "conflict" in overwriteMode option when saving documents using the Collection API

Graph API

Added graphVertexCollection.vertexExists and graphEdgeCollection.edgeExists methods

These mimic the behavior of the collection.documentExists method but using the Graph API.
Added graphVertexCollection.collection and graphEdgeCollection.collection

These properties now provide access to regular (non-graph) collection objects for these graph collections. These objects can be used to perform operations not available within the context of a graph (e.g. bulk imports or modifying the collection itself).
Added support for isDisjoint option in Graph API

Cursor API

Added cursor.flatMap method

This method behaves similarly to the Array method flatMap but operates on the cursor directly like cursor.map does.
Added cursor.batches to provide a batch-wise cursor API
Added support for for await in ArrayCursor (#616)

It is now possible to use for await to iterate over each item in a cursor asynchronously.

View API

Added support for primarySortCompression and storedValues options in View API

Fixed

General

Removed TypeScript dependency on dom library

If you are using arangojs in Node.js, you no longer need to add the dom library to your tsconfig.json configuration.

Database API

Fixed db.dropFunction option group being ignored
Fixed documentation of db.runServiceTests

Previously the documentation incorrectly indicated that the default value of the idiomatic option is true. The correct default value is false.

6.14.1 - 2020-05-01

Fixed

Added uuid and padded to legal KeyGeneratorType values in TypeScript (#656)
Added overwrite to InsertOptions type in TypeScript (#657)

6.14.0 - 2020-03-18

Added

Added db.listTransactions and db.transactions methods

6.13.0 - 2020-01-24

Changed

Empty querystring parameters are now omitted

In some cases ArangoDB would be unable to correctly handle querystring parameters without values. Any paremeters set to undefined will now no longer be added to the querystring.

This does not affect parameters set to empty string values.

Added

Added maxRuntime option to db.query method

Fixed

Replaced linkedlist dependency with x3-linkedlist (#601)

The linkedlist dependency had a memory leak and was no longer maintained. The replacement should fix this issue.

6.12.0 - 2019-10-16

Added

Added cursor.kill method

Cursors that have not yet been fully depleted can now be killed using the cursor.kill method. Note that this method has no effect if the cursor is already depleted.
Added cursor.nextBatch method

Cursors normally fetch additional batches as necessary while iterating over the individual results, this method allows consuming an entire batch at a time.

6.11.1 - 2019-08-30

Fixed

Fixed View properties not being passed correctly when creating Views (#621)
Renamed internal response.host attribute to response.arangojsHostId (#604)

In some environments the host attribute is already present and read-only. This should avoid a TypeError being thrown when a value is assigned by arangojs.

6.11.0 - 2019-08-16

Changed

Renamed db.transaction to db.executeTransaction

The method for executing server-side transactions is now called executeTransaction and the params argument now must be passed via the options object.

For backwards-compatibility the new db.transaction method will continue to behave like before when passed an action string as the second argument. Note that this behavior is deprecated and will be removed in arangojs 7.

Added

Added support for ArangoDB 3.5 streaming transactions

New streaming transactions can be created using db.beginTransaction and existing streaming transactions can be accessed by passing the transaction ID to db.transaction.

See the documentation of the transaction.run method for examples of using streaming transactions with arangojs.
Added support for ArangoDB 3.5 Analyzers API

See the documentation of the database.analyzer method and the Analyzer instances for information on using this API.
Added collection.getResponsibleShard method
Added support for new ArangoDB 3.5 collection properties
Added support for new ArangoDB 3.5 View properties

Fixed

Fixed a problem causing empty nested AQL expressions to be converted to bind variables

Nesting an empty AQL expression like the result of calling aql.join with an empty array would previously result in the AQL expression not being recognized and being converted to an object bind variable instead.

6.10.0 - 2018-12-22

Changed

Changed Views API to match 3.4 GA implementation

This release updates the Views API to the version implemented in the final ArangoDB 3.4 GA release. Please note that these changes may break code written for earlier ArangoDB 3.4 release candidates.

Added

Added timeout option to db.query and request methods (#572)

Note that this merely cancels the request. Queries will still be executed and ArangoDB will still continue processing the request, this will merely result in the socket being forcefully disconnected.
Added query management API (#474)

This implements most endpoints of the HTTP Interface for AQL Queries.

6.9.0 - 2018-11-07

Changed

Restored support for credentials in URLs

If the server URL includes credentials, arangojs will now use them instead of the default username "root" and an empty password. Any credentials explicitly set using useBasicAuth or useBearerAuth will still override the default credentials as before.

6.8.0 - 2018-11-07

Changed

Added any[] to allowed types for AQL bind parameters

This should help in some cases where the previous TypeScript annotation was too restrictive.

Added

Added support for UNIX socket URLs (#405)

In addition to the unix:///socket/path and http+unix:///socket/path URL formats recognized by ArangoDB, arangojs also supports the format http://unix:/socket/path commonly supported in the Node ecosystem and automatically converts ArangoDB endpoint URLs between them.

6.7.0 - 2018-10-24

Changed

No longer emitting undefined values in aql template strings

Previously using undefined values in an aql template string would result in a bind parameter being added with no value, which would always lead to an error response when ArangoDB executes the query. Now undefined values will simply be omitted, also easing the conditional insertion of query fragments.
Changed experimental Views API

This release updates the experimental support for the Views API to the version implemented in the ArangoDB 3.4 release candidate. Please note that this API is still subject to change and may indeed still change until the 3.4.0 GA release.
Updated TypeScript to version 3

This may result in type signatures that are incompatible with TypeScript 2 being added in future releases (including patch releases).

Added

Added nesting support for aql template strings (#481)

It is now possible to use aql queries as values in aql template strings:

function createQuery(flowers, color) {
  const filter = color ? aql`FILTER flower.color == ${color}` : undefined;
  return aql`FOR flower IN ${flowers} ${filter} RETURN flower`;
}
createQuery(db.collection("flowers", "green"));
// FOR flower IN @@value0 FILTER @value1 RETURN flower
// {"@value0": "flowers", "value1": "green"}
createQuery(db.collection("flowers"));
// FOR flower IN @@value0  RETURN flower
// {"@value0": "flowers"}

Previously aql fragments could only be created with aql.literal, which does not support bind parameters:

aql.literal("FILTER flower.color == " + JSON.stringify(color));
// Note that we had to rely on JSON.stringify to correctly escape the value
// because the value is part of the literal, not a bind parameter

Added support for undefined and AQL literals to aql.literal

Passing undefined to aql.literal will now result in an empty literal as would be expected. Passing an AQL literal back into aql.literal will return the existing literal rather than the string [object Object].

Added aql.join function

The function aql.join can be used to convert an array of aql queries into a combined query:

const users = db.collection("users");
const keys = ["a", "b", "c"];
const fragments = keys.map((key) => aql`DOCUMENT(${users}, ${key})`);
const combined = aql`[${aql.join(fragments, ", ")}]`;
// [DOCUMENT(@@value0, @value1), DOCUMENT(@@value0, @value2), \
// DOCUMENT(@@value0, @value3)]
// {"@value0": "users", "value1": "a", "value2": "b", "value3": "c"}
const query = aql`FOR user IN ${combined} RETURN user.email`;
// FOR user IN [DOCUMENT(@@value0, @value1), DOCUMENT(@@value0, @value2), \
// DOCUMENT(@@value0, @value3)] RETURN user.email
// {"@value0": "users", "value1": "a", "value2": "b", "value3": "c"}

Added allowDirtyRead option to db.query and collection.document

Dirty reads are supported in leader/follower replication setups and require ArangoDB 3.4 or later. When performing a request that permits dirty reads, arangojs will load balance across all know leaders and followers and instruct ArangoDB to allow responding with stale or dirty response data. Note that data returned from a dirty read may be out of date or inconsistent.

6.6.0 - 2018-08-28

Changed

Re-implemented collection.import

The previous implementation was broken. The new implementation should be backwards-compatible in cases where it previously wasn't broken but is more flexible and also handles buffers.

Fixed

Added missing dependency on @types/node (#567)

This should solve TypeScript errors when the dependency was not already added.

6.5.1 - 2018-08-15

Fixed

Fixed edgeCollection.save not respecting options (#554)
Fixed database.createDatabase TypeScript signature (#561)

6.5.0 - 2018-08-03

Changed

Requests that fail because a server can not be reached are now automatically retried if other servers are available

This behavior can be controlled using the maxRetries option.
Renamed EdgeCollection#edge to EdgeCollection#document

EdgeCollection#edge is now an alias for the document method.
Renamed GraphEdgeCollection#edge to GraphEdgeCollection#document

GraphEdgeCollection#edge is now an alias for the document method.
Renamed GraphVertexCollection#vertex to GraphVertexCollection#document

GraphVertexCollection#vertex is now an alias for the document method.

Added

Added maxRetries option to configuration to control retry behavior
Added collection.documentExists method
Added graceful option to collection.document

6.4.0 - 2018-07-06

Changed

Added TypeScript validation for opts in DocumentCollection#save

Added

Added ArangoError and CollectionType to public exports
Added database.close method
Added opts parameter to EdgeCollection#save

6.3.0 - 2018-06-20

Added

Added database.version method
Added database.login method
Added database.exists method
Added collection.exists method
Added graph.exists method
Added aql.literal function
Exposed typings for collections and graphs (@samrg472 in #538)

Fixed

Fixed synchronous errors during request creation not being handled

Internal errors thrown while a request is created (e.g. malformed URIs) would result in unhandled errors, which could result in termination of the process or promises never being rejected. These errors are now handled normally and will result in async rejections as expected.

6.2.4 - 2018-04-27

Fixed

Ensure res.body is an empty string instead of null in the browser version

6.2.3 - 2018-04-03

Fixed

Fixed collection.update(documentHandle, newValue, opts) missing return value
Fixed collection.removeByKeys(keys, options) missing return value
Fixed collection.replaceByExample(example, newValue, opts) missing return value
Fixed collection.updateByExample(example, newValue, opts) missing return value

6.2.2 - 2018-03-21

Fixed

Replaced Object.values use to improve Node version compatibility

This allows using arangojs in Node.js 6 LTS without a polyfill.

6.2.1 - 2018-03-21

Changed

Moved most documentation out of the README (#123)

This is a necessary step to integrate arangojs with the Drivers book in the official ArangoDB documentation.
Replaced internal use of async functions with callbacks

This removes some unnecessary layers of indirection, which should increase overall performance.

Fixed

Increased test coverage (#34).

6.2.0 - 2018-03-06

Changed

Extended db.transaction arguments (@f5io in #494)

It's now possible to pass additional transaction options.

Fixed

Fixed db.acquireHostList request path (@jcambass in #504)
Fixed a typo (@lodestone in #506)
Fixed graphEdgeCollection.edge return value (@Hunter21007 in #501)
Fixed graph API sending incorrect requests resulting in HTTP 400 errors (@casdevs in #513)

6.1.0 - 2018-02-12

Removed

Removed ES modules build

This should solve compatibility problems with es6-error. The cjs build now should also work with emulated ES module imports.

Changed

Use cpy-cli for build process

Should help with cross-platform compatibility.

Fixed

Fixed db.uninstallService(mount, opts) opts default value
Fixed db.getServiceConfiguration(mount, minimal) minimal representation
Fixed db.getServiceDependencies(mount, minimal) minimal representation
Fixed db.updateServiceConfiguration(mount, cfg, minimal) non-minimal representation
Fixed db.replaceServiceConfiguration(mount, cfg, minimal) non-minimal representation
Fixed db.updateServiceDependencies(mount, cfg, minimal) non-minimal representation
Fixed db.replaceServiceDependencies(mount, cfg, minimal) non-minimal representation
Fixed handling of non-json responses

6.0.1 - 2018-01-22

Changed

Use rimraf for build process

Should help with cross-platform compatibility.

Fixed

Fixed some imports broken during the TypeScript rewrite

If you were previously seeing errors involving a default property, this should make those go away.

6.0.0 - 2018-01-11

Removed

Removed retryConnection config.

It is not possible to reliably determine whether retrying a request is safe or not at the driver level. If you need automatic retry, you should implement your own logic, e.g. using the retry package.
Removed promise config.

If you want to use an alternative promise implementation you need to overwrite the Promise global variable directly.
Asynchronous functions no longer support node-style callbacks.

All asynchronous functions now return promises.
Removed support for credentials in url config.

Use db.useBasicAuth or db.useBearerAuth to pass credentials instead.
Removed bower support.

Use yarn/npm instead.

Changed

Removed lib path prefix

All arangojs files can now be imported directly by name.

Before:

import { DocumentCollection } from "arangojs/lib/collection";

After:

import { DocumentCollection } from "arangojs/collection";

The url config can now also be an array of URLs.

The behavior depends on the load balancing strategy (see API docs).
The databaseName config has been replaced with isAbsolute.

If you previously used databaseName: false, the same behavior can now be achieved using isAbsolute: true. If you want to use a specific database you can still switch databases with db.useDatabase at any time.
Browser: maximum number of parallel connections behaves differently.

As keep-alive does not work reliably in the browser, the maximum number of parallel connections now matches agentOptions.maxSockets exactly.
TypeScript: ported arangojs to TypeScript.

The generated typings are now included in the NPM release and should be more reliable than the community maintained typings included with earlier versions of arangojs. See also #480.

Added

Added ES Modules and browser build to NPM release.
- ES Modules files live under lib/esm/
- CommonJS files live under lib/cjs/
- Precompiled browser build lives at lib/web.js
Added support for load balancing and failover.

See API documentation for details.
Added acquireHostList method.

See API documentation for details.
Added support for leader/follower failover.

Connections to a follower responding with an endpoint redirect will now be transparently redirected to the indicated leader.

Fixed

Fixed #354

Graph methods now only return the relevant part of the response body.
