How to Use package.json Scripts to Automate Tasks

Basic Scripts

{
  "scripts": {
    "dev": "astro dev",
    "build": "astro build",
    "preview": "astro preview",
    "lint": "eslint src/",
    "deploy": "npm run build && wrangler deploy"
  }
}

npm run dev
npm run build

Special Script Names

Script name	How to run
start	npm start (no run needed)
test	npm test (no run needed)
prebuild	Runs automatically before build

Common Pitfalls

• && may not work on Windows — use cross-env or separate scripts
• npm start and npm test don’t need the run keyword

To run these scripts automatically in CI, combine with GitHub Actions: Basic Auto-Deploy Setup.
