A tiny tool to run `tsc` on specific files without ignoring tsconfig.json ignoring imports and imports of imports

tsc-files-ignore-imports

A tiny tool to run tsc on specific files with ignoring the imports and without ignoring tsconfig.json.

Installation

npm i -D tsc-files-ignore-imports

yarn add -D tsc-files-ignore-imports

Why

I wanted to type-check only the staged files with ignoring imports and the imports of the imports with lint-staged.

Unfortunately passing specific files like tsc --noEmit file1.ts file2.ts will cause TypeScript to simply ignore your tsconfig.json.

There's already an open issue in the TypeScript repo to support this use case — you may want to give a 👍 there: microsoft/TypeScript#27379

Usage

With lint-staged:

{
  "lint-staged": {
    "**/*.ts": "tsc-files-ignore-imports --noEmit"
  }
}

add tsconfig.autoGenerated.json to .gitIgnore

How it works

For the most part, it just forwards all arguments to tsc with one exception: the specified files will not be forwarded — instead, they will be put at the files property of a temporary config that will be generated next to your original tsconfig.json. then it will filter out the errors and catch only the ones from the files.
