v5.0.0

Major Changes

• 2f4f2a7: # FEATURES

  • allow for multiple Throttler Contexts
  • allow for conditionally skipping based on ThrottleGuard#shouldSkip method
  • allow for easily overriding throttler message based on guard method
  • extra context passed to throw method for better customization of message
  • ThrottlerStorage no longer needs a storage property`
  • getTracker can now be async

  BREAKING CHANGES

  • ttl is now in milliseconds, not seconds, but there are time helper exposed to
    ease the migration to that
  • the module options is now either an array or an object with a throttlers
    array property
  • @Throttle() now takes in an object instead of two parameters, to allow for
    setting multiple throttle contexts at once in a more readable manner
  • @ThrottleSkip() now takes in an object with string boolean to say which
    throttler should be skipped
  • ttl and limit are no longer optional in the module's options. If an option
    object is passed, it must define the defaults for that throttler

  HOW TO MIGRATE

  For most people, wrapping your options in an array will be enough.

  If you are using a custom storage, you should wrap you ttl and limit in an
  array and assign it to the throttlers property of the options object.

  Any @ThrottleSkip() should now take in an object with string: boolean props.
  The strings are the names of the throttlers. If you do not have a name, pass the
  string 'default', as this is what will be used under the hood otherwise.

  Any @Throttle() decorators should also now take in an object with string keys,
  relating to the names of the throttler contexts (again, 'default' if no name)
  and values of objects that have limit and ttl keys.

  IMPORTANT: The ttl is now in miliseconds. If you want to keep your ttl
  in seconds for readability, usethe seconds helper from this package. It just
  multiplies the ttl by 1000 to make it in milliseconds.

v4.2.1

Patch Changes

• b72c9cb: Revert resolvable properties for ttl and limit

  The resolvable properties made a breaking change for custom guards that was
  unforseen. This reverts it and schedules the changes for 5.0.0 instead

v4.2.0

Minor Changes

• d8d8c93: Allow for ttl and limit to be set based on the execution context, instead of statically assigned for the entire application

v4.1.0

Minor Changes

• 527d51c: Support Nest v10

v4.0.0

Major Changes

• 4803dda: Rewrite the storage service to better handle large numbers of operations

  Why

  The initial behavior was that getRecord() returned an list of sorted TTL
  timestamps, then if it didn't reach the limit, it will call addRecord().
  This change was made based on the use of the Redis storage community package
  where it was found how to prevent this issue. It was found out that
  express-rate-limit
  is incrementing a single number and returning the information in a single
  roundtrip, which is significantly faster than how NestJS throttler works by
  called getRecord(), then addRecord.

  Breaking Changes

  • removed getRecord
  • addRecord(key: string, ttl: number): Promise<number[]>; changes to increment(key: string, ttl: number): Promise<ThrottlerStorageRecord>;

  How to Migrate

  If you are just using the throttler library, you're already covered. No
  changes necessary to your code, version 4.0.0 will work as is.

  If you are providing a custom storage, you will need to remove your current
  service's getRecord method and rename addRecord to incremenet while
  adhering to the new interface and returning an ThrottlerStorageRecord object

v3.1.0

Minor Changes

• da3c950: Add skipIf option to throttler module options

  With the new option, you can pass a factory to skipIf and determine if the throttler guard should be used in the first palce or not. This acts just like applying @SkipThrottle() to every route, but can be customized to work off of the process.env or ExecutionContext object to provide better support for dev and QA environments.

v3.0.0

Major Changes

• c9fcd51: Upgrade nest version to v9. No breaking changes in direct code, but in nest v9 upgrade

v2.0.1

Patch Changes

• cf50808: fix memory leak for timeoutIds array. Before this, the timeoutIds array would not be trimmed and would grow until out of memory. Now ids are properly removed on timeout.

Features

• adding in a comment about version (b13bf53)

BREAKING CHANGES

• v2 and above is now being developed specificially for
  nest v8 and could have some unforseen side effects with Nest v7. use with
  v7 at your own risk.
