A tiny tool to run tsc on specific files without ignoring tsconfig.json.

English | 简体中文

Fork from gustavopch/tsc-files, and support the Typescript in Vue.

npm i -D vue-tsc-files

yarn add -D vue-tsc-files

I wanted to type-check only the staged files 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

With lint-staged:

{
  "lint-staged": {
    "*.{vue,ts}": "vue-tsc-files --noEmit"
  }
}

Vue-tsc-files can auto search d.ts from root or src dir. If you have more, you can add there in lint-staged.config.js

const declarationFiles = ['src/global.d.ts', 'src/shims-vue.d.ts']

module.exports = {
  '*.{vue,ts}': (filenames) => {
    const files = [...filenames, ...declarationFiles]
    return `vue-tsc-files ${files.join(' ')} --noEmit --skipLibCheck`
  },
}

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. Other than that, just read tsc --help.
