Building and Testing Node.js

This guide shows you how to build and test a Node.js application.

Example Workflow

name: nodejs-build

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
    - name: Use Node.js
      uses: actions/setup-node@v4
      with:
        node-version: '20'
    - run: npm ci
    - run: npm run build --if-present
    - run: npm test

Detailed Explanation

1. Use Node.js: actions/setup-node installs the specified Node.js version.
2. npm ci: Installs dependencies strictly from package-lock.json (faster and more reliable for CI than npm install).
3. npm run build: Runs the build script defined in your package.json.
4. npm test: Runs the test script.
