Work with lint-staged, run tsc on staged files and output the result of staged-only files.

⚠️ ONLY TESTED ON TYPESCRIPT 5

Setup

• Install lint-staged, follow the instructions.

• Install tslint, use:

  npm i -D @hong97/tslint

• In package.json, add tslint to *.ts, *.tsx files.

  "lint-staged": {
    "*.{ts,tsx}": [
      "tslint"
    ]
  },

• Use Husky or other methods to set up your git 'pre-commit' hooks.

• Now, TypeScript will be checked at commit staged.

Configuration

Create a file named tslintconfig.js in your root directory:

module.exports = {
  alwaysInclude: [
    // always included in tsc process no matter these files are staged or not
  ],
  ignore: [
    // use glob pattern, see more: https://www.npmjs.com/package/minimatch
  ],
};

You can also set up a callback hook in config file:

module.exports = {
  onFinish: (result) => {
    // ...
  } 
};

The callback will be invoked after tslint finish running and the results will be passed through.
