Mark file as skips typechecking if it contains ts-nocheck by sheetalkamat · Pull Request #58593 · microsoft/TypeScript

Sheetal Nandi (sheetalkamat) · 2024-05-20T19:10:26Z

This is different take on #58592 to skip checking only if no-checkJs
Frankly i dont know what all will fail because we dont have enough coverage for js + incremental as such from this perspective.

cc: Wesley Wigham (@weswigham)

From investigating #56956

Needs #58364 to work correctly for js emit

Sheetal Nandi (@sheetalkamat) Here are the results of running the top 400 repos comparing main and refs/pull/58593/merge:

Everything looks good!

Sheetal Nandi (sheetalkamat) · 2024-05-21T19:46:57Z

Does this need to wait for #58364 given the ts-nocheck files may be emitting js?

Wesley Wigham (weswigham) · 2024-05-21T22:36:09Z

Does this need to wait for #58364 given the ts-nocheck files may be emitting js?

Either that or, like the other PR, only enabled when only .d.ts emit is performed by the checker in question.

Sheetal Nandi (sheetalkamat) · 2024-05-22T16:34:11Z

Either that or, like the other PR, only enabled when only .d.ts emit is performed by the checker in question.

Thats tough I think and not work flowing information temporarily till we get the PR in so i will just wait for that PR to merge.

Jake Bailey (jakebailey) · 2024-05-30T23:19:32Z

#58364 is in, so is this safe to update and get in?

Wesley Wigham (weswigham) · 2024-05-30T23:24:41Z

Yeah, just remember the condition in calculateNodeCheckFlagWorker in checker.ts and emitJsFileOrBundle in emitter.ts needs to swap from just compilerOptions.noCheck to something that can handle this, too. (probably just the skipTypeChecking util function this edits, unless you wanna do the piecemeal thing emitDeclarationFileOrBundle does - but that should probably just swap to skipTypeChecking, too)

Sheetal Nandi (sheetalkamat) · 2024-05-31T00:14:50Z

Wesley Wigham (@weswigham) pls review again. I have merged with main and added those checks

Also i used canIncludeBind* function instead of skipsTypeChecking to avoid having to do extra checks (or get sourceFile if not needed)
