My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

Previously, typescript-eslint switched from glob to globby for tsconfig.json file searching: #2418

Under the hood, globby is powered by fast-glob with extra features, but none of them are utilized by the typescript-eslint.

Since the typescript-eslint doesn't utilize those extra features, I propose replacing globby with fast-glob to reduce the installation size.

Additional Info

The installation size difference

The installation size of globby is 605 KiB and 23 transitive dependencies are introduced, while the installation size of fast-glob is 503 KiB and 18 transitive dependencies are introduced.

Proof of Concept

I've tested the proposal in my fork: SukkaW@0cec339 and all existing test cases are passed on my machine.

globby's extra features

Here is globby's feature description:

• Promise API
  • fast-glob also has promise-based API, and typescript-eslint only uses the sync API
• Multiple patterns
  • globby's multiple patterns support is powered by fast-glob directly
• Negated patterns: ['foo*', '!foobar']
  • globby's negated patterns support is also powered by fast-glob directly
• Expands directories: foo → foo/**/*
  • typescript-eslint doesn't rely on this feature since the exact matches of tsconfig.json (-like) files are required
• Supports .gitignore and similar ignore config files
  • typescript-eslint doesn't rely on this feature since globby disabled this feature by default and typescript-eslint doesn't enable it.
• Supports URL as cwd
  • Currently typescript-eslint passed the string path to cwd, and we can use Node.js built-in url.fileURLToPath in case we encounter URLs in the future.
