We will use ES Modules throughout the tutorial.

Open package.json and configure the module system and scripts.

The type module property allows us to use import and export syntax.

The development script uses Node.js watch mode to restart the server when files change.

{
  "name": "nodejs-rest-api",
  "version": "1.0.0",
  "private": true,
  "type": "module",
  "scripts": {
    "start": "node src/server.js",
    "dev": "node --watch src/server.js",
    "test": "node --test"
  }
}
