Github Actions have everything that you need to run your eslint out of the box now, to do that simply use the run commands like so:

name: CI
on: push
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Install modules
      run: yarn
    - name: Run ESLint
      run: eslint . --ext .js,.jsx,.ts,.tsx

This action executes ESLint linter on specified javascript files without any previous action/build step or Docker required.

You must have the ESLint running locally for the action to execute. It will use the same rules as you do locally. More info on the ESLint getting started guide

Add to your existing main.yml file or create a new file named .github/workflows/lint.yml and copy over one of the examples below to your new workflow file

This is the simplest example to get it running:

name: Lint

on: [push]

jobs:
  eslint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - uses: stefanoeb/[email protected]

By default it will run ESLint through all the files in the project. But you can also specify a glob of files to lint using the with: argument on your YAML file. The example below shows ESLint running only on the files under the src/ folder:

name: Lint

on: [push]

jobs:
  eslint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - uses: stefanoeb/[email protected]
        with:
          files: src/

If there is no previous step installing the necessary modules, this action will execute a yarn install or npm install automatically.
