Its non-blocking event loop handles many requests at once, and Express makes routing simple. This tutorial walks you through the core steps to get a working API running locally.<\/p>\n<p>You only need Node.js installed and a terminal. Everything else installs with npm.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/09\/article-1789556426718.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>1. Set Up the Project<\/h2>\n<p>Create a folder and initialize it:<\/p>\n<ul>\n<li><code>mkdir my-api &amp;&amp; cd my-api<\/code><\/li>\n<li><code>npm init -y<\/code><\/li>\n<li><code>npm install express<\/code><\/li>\n<\/ul>\n<h2>2. Create the Server<\/h2>\n<p>Create <code>server.js<\/code> and start a basic Express app:<\/p>\n<ul>\n<li>Import Express and call <code>express()<\/code><\/li>\n<li>Add <code>app.use(express.json())<\/code> to parse JSON bodies<\/li>\n<li>Listen on port 3000 with <code>app.listen()<\/code><\/li>\n<\/ul>\n<h2>3. Define REST Routes<\/h2>\n<p>REST maps HTTP verbs to actions. For a simple user list:<\/p>\n<ul>\n<li><code>GET \/users<\/code> \u2014 return all users<\/li>\n<li><code>GET \/users\/:id<\/code> \u2014 return one user<\/li>\n<li><code>POST \/users<\/code> \u2014 create a user from <code>req.body<\/code><\/li>\n<li><code>PUT \/users\/:id<\/code> \u2014 update a user<\/li>\n<li><code>DELETE \/users\/:id<\/code> \u2014 remove a user<\/li>\n<\/ul>\n<p>Read parameters with <code>req.params.id<\/code> and always send proper status codes like 200, 201, or 404.<\/p>\n<h2>4. Test and Improve<\/h2>\n<p>Run <code>node server.js<\/code> and test with Postman or curl. Store data in memory first, then swap in a database such as MongoDB or PostgreSQL. Add middleware for logging, validation, and error handling as the API grows.<\/p>\n<h2>Conclusion<\/h2>\n<p>Building a REST API with Node.js and Express takes minutes, not days. Start with clean routes, return correct status codes, and layer in persistence and security once the basics work.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Build a REST API with Node.js: A Beginner-Friendly Tutorial Node.js is one of the fastest ways to build a REST API.
