ESLint Action

This is a GitHub Action that runs ESLint for .js, .jsx, .ts and .tsx files using your .eslintrc rules. It's free to run and it'll annotate the diffs of your pull requests with lint errors and warnings.

Neat! Bet your CI doesn't do that.

Usage

.github/workflows/lint.yml:

name: Lint

on: pull_request

jobs:
  eslint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: hallee/eslint-action@1.0.3
