GitHub Actions provides a great way to automate workflow processes and make development and deployment more efficient. Linting is an important part of any software development project to ensure code consistency and maintain uniform standards. In this post, I will explain how to setup a Github Actions workflow lint to automate your linting process.

Setting up a GitHub Actions workflow lint is easy and can help keep your codebase consistent and maintainable.

First, you need to create a workflow file in your project’s root directory. This file should be named .github/workflows/lint.yml and should contain the configuration necessary to run your linting script.

Let’s say your package.json file looks like this:

"scripts": {
    (...)
    "lint": "eslint --ignore-path .gitignore . --ext .js"
  },

Create a file at ./github/workflows/lint.yml

Paste this content:

name: lint

on: push

jobs:
  lint:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Cache node modules
        uses: actions/cache@v2
        env:
          cache-name: cache-node-modules
        with:
          path: ~/.npm
          key: ${{ runner.os }}-build-${{ env.cache-name }}-${{ hashFiles('**/package-lock.json') }}
          restore-keys: |
            ${{ runner.os }}-build-${{ env.cache-name }}-
            ${{ runner.os }}-build-
            ${{ runner.os }}-
      - name: Install Dependencies
        run: npm install

      - name: Lint
        run: npm run lint
