Provide builtin read only file to web worker

[dimitrisfasoulas]

Hello. First of all, thank you for the wonderful job done with Langium. It is a joy to work with.

I have a question regarding providing a built-in library file to Monaco through the web worker.

In the BuiltIn Libraries guide there is a clear example of how to achieve this.

However, the last part that provides the file through a custom FileSystemProvider is VsCode specific and will not work with Monaco on the web.

As a result although I can use the build in library on Monaco and its exported nodes appear for autocompletion, peek definitions or go to references shows an empty file (although it has a correct references number and line numbers)

and an error is thrown in the console:

chunk-UZ2VXBV6.js?v=b363b4ac:175253 Uncaught (in promise) Error: Unable to resolve resource builtin:/builtin.mylang
   at ResourceModelCollection2.doCreateReferencedObject (chunk-UZ2VXBV6.js?v=b363b4ac:175253:11)
   at ResourceModelCollection2.doCreateReferencedObject (chunk-UZ2VXBV6.js?v=b363b4ac:175251:19)
   at async AsyncReferenceCollection.acquire (chunk-CMPQUMOX.js?v=b363b4ac:2589:26)

   at async ReferenceWidget2._revealReference (chunk-UZ2VXBV6.js?v=b363b4ac:94426:17)

I was wondering if there is a way to achieve something similar for the web.

Hey @dimitrisfasoulas,

you're probably better off asking in a repo that's more dedicated to monaco. Probably at monaco-languageclient or the monaco repo itself.
