Resolve only relative references tree in the project (in syntax only mode)

[sheetalkamat]

This resolves and follows all relative module references instead of just in open files

[sheetalkamat]

@DanielRosenwasser The relative reference resolutions are also dependent on rootDirs option in config file. I am wondering if we should create inferred configured project that only reads options from config file and not file list so we give more accurate result.. Thoughts?

Heya @sheetalkamat, I've started to run the tarball bundle task on this PR at 5387cde. You can monitor the build here.

[DanielRosenwasser]

I'm not quite as concerned with rootDirs, but maybe that's a bias of not having seen it nearly as much. If we're willing to read the tsconfig.json, then we probably also want to respect path mappings from the paths field too.

[DanielRosenwasser]

By the way, what's the difference between this and #39476?

[DanielRosenwasser]

Oh, is the idea that you would load up the entire project except for non-relative modules (e.g. node_modules imports)? From a gut feel, I don't think that that's desirable. I think a lot of codebases are large enough from their own size and we really want to minimize program construction time.

[sheetalkamat]

Thats correct.. It constructs relative reference tree and ignores node_module imports.
The other one just resolves only in open file (only relative references)

Hey @sheetalkamat, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/79104/artifacts?artifactName=tgz&fileId=11930698DC3312C59AF49D30296B7784B5F0BAA312D949B81C2C9A5C62932C9702&fileName=/typescript-4.0.0-insiders.20200707.tgz"
    }
}

and then running npm install.

Hey @sheetalkamat, something went wrong when looking for the build artifact. (You can check the log here).

[sheetalkamat]

Closing this since we definitely dont want whole tree.
