Type definition errors

[Vinnl]

Since #356, rdflib ships a TypeScript type defintion file index.d.ts that refers to other files in the same directory (i.e. it contains statements like import BlankNode from './blank-node'; import Collection from './collection'; // etc.), but those files are not generated. This results in TypeScript compilation errors for downstream projects:

node_modules/rdflib/lib/index.d.ts(1,23): error TS7016: Could not find a declaration file for module './blank-node'. '/home/travis/build/solid/solid-ui/node_modules/rdflib/lib/blank-node.js' implicitly has an 'any' type.

node_modules/rdflib/lib/index.d.ts(2,24): error TS7016: Could not find a declaration file for module './collection'. '/home/travis/build/solid/solid-ui/node_modules/rdflib/lib/collection.js' implicitly has an 'any' type.

# etc.

#363 should fix this, includes many types. I'll modify the .npmignore in a future PR.

Make sure that it's .npmignore, not .gitignore :) git revert c097d1a4797a22724e13f178461377a608637e8e should be sufficient.

Gotcha!

When installing rdflib v1.0.6 in a typescript project and writing import rdf from 'rdflib', I get:

error TS7016: Could not find a declaration file for module 'rdflib'. '[path/to]/node_modules/rdflib/lib/index.js' implicitly has an 'any' type.
  Try `npm install @types/rdflib` if it exists or add a new declaration (.d.ts) file containing `declare module 'rdflib';`

Since the @types/rdflib was deprecated, the available options are to declare the module manually (no types) or install @types/[email protected] (may be out of date).

Are there any other solutions available at the moment?

[Vinnl]

@mrkvon They shouldn't have been deprecated yet, see DefinitelyTyped/DefinitelyTyped#42044

You can either attempt to install an earlier version of those type definitions, wait until my PR at DT has been accepted, or use the prerelease version of rdflib (npm install rdflib@next) at your own risk.

is this fixed yet?
I get the same errors when trying to compile a package that uses rdflib v1.3.1 as a dependency

[Vinnl]

@ludwigschubi yes, this should have been fixed - the release with TS support was 1.0.7 IIRC. I guess it's probably better for you to report a separate bug that can focus wholly on your issue - I'll close this one.

This is still a problem if your TS project has "noImplicitAny=true", because plain js files (e.g. query.js) do not get transpiled to .d.ts .
Here's a PR that works for me : #513 .

Hello,

I am trying to use rdflib (version 2.2.32) with Typescript, and I cannot get it to work.
Could that be the same type declaration issue ?

On the other hand, VS Code Intellisense does recognize rdf reference, and points to index.d.ts when I "go to definition"

import rdf from 'rdflib';

const store = rdf.graph();  => throws 'Cannot read properties of undefined (reading \'graph\')'

I tried setting "noImplicitAny" to 'false' in tsconfig.json, but it didn't solve the issue.

Apologies in advance if I am missing the obvious...
