Description

lint-staged ignores tsconfig.json when it called through husky hooks (see "Steps to reproduce")

Steps to reproduce

Create these files (test.js, tsconfig, package.json):

test.ts

export class Test {
  static get observedAttributes() {
    return ['foo'];
  }
}

tsconfig.json

{
  "compilerOptions": {
    "target": "ESNEXT"
  }
}

package.json

{
  "husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  },
  "lint-staged": {
    "*.{js,ts}": [
      "tsc --noEmit"
    ]
  }
}

Then on command line write:

// everything works fine (it uses tsconfig.json)!
tsc --noEmit

// throw an error because it ignores tsconfig.json
git commit // error TS1056: Accessors are only available when targeting ECMAScript 5 and higher
