Fork-ts-checker-webpack-plugin: Plugin doesn't run for project references

[MLoughry]

Much like tslint and (to an extent) ts-loader, it seems this project doesn't yet fully support Typescript>=3.0.0 style project references. If I introduce an error into a dependent project, fork-ts-checker-webpack-plugin doesn't find the error.

If you'd like to have a crack at adding support you'd be most welcome! cc @andrewbranch - author of project reference support in ts-loader in case he has any thoughts 🌻♥️

I believe that, like TypeStrong/ts-loader#851, this ultimately requires the new Typescript APIs yet to be implemented and tracked by Microsoft/Typescript#28640.

I may look into making such a contribution once the APIs are available, to learn them for my own needs; but I don't think it's worthwhile to do so before then.

The new API was added in https://github.com/microsoft/TypeScript/pull/31432 and has been released in Typescript v3.6 so this should be unblocked now. Unfortunately, I don't know enough about how this plugin or the typescript API works to really tackle this myself yet.

There is any update on this feature? Currently my build it's ok with ts-loader but would be nice to be able to speed the compilation time by forking the type checking

We are working on the major refactor of the plugin internals as a 5.0.0 release. The new implementation should support project references out of the box :)

Is there any updates on this? Would like to be able to use this & ts-loader with projectReferences.

Currently, I'm focusing on refactoring and I hope I will release an alpha version in the next month. It's a huge task and I have limited time to work on it :)

Hey all,

The amazing @sheetalkamat is busy improving the project references support in ts-loader in https://github.com/TypeStrong/ts-loader/pull/1076

Part of the discussion is around how transpileOnly should work alongside fork-ts-checker-webpack-plugin. Feel free to be part of the discussion 🌻🥰

@MLoughry , @noahm , @sikloidz , @Ivaylo-Lafchiev
Please try fork-ts-checker-webpack-plugin@alpha - I've published a new version which supports project references 🚀
I will close this issue to clean-up the backlog :)
