In this tutorial, you&#8217;ll create a simple, functional API using Express, the de facto framework for Node.js.<\/p>\n<p>First, initialize your project folder by running <code>npm init -y<\/code>, then install Express with <code>npm install express<\/code>.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/via.placeholder.com\/800x600\/4a90d9\/ffffff?text=how%20to%20create%20a%20rest%20api%20with%20node%20js\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>Set Up the Express Server<\/h2>\n<p>Create a file named <code>server.js<\/code>. Import Express, add the <code>express.json()<\/code> middleware for parsing JSON bodies, and start the server on port 3000.<\/p>\n<pre><code>const express = require('express');\nconst app = express();\napp.use(express.json());\napp.listen(3000, () => console.log('API running'));<\/code><\/pre>\n<h2>Design the Routes<\/h2>\n<p>A REST API relies on CRUD operations. Use a simple in-memory array as your data store and define these endpoints:<\/p>\n<ul>\n<li><strong>GET \/items<\/strong> \u2014 fetch all items<\/li>\n<li><strong>POST \/items<\/strong> \u2014 create a new item<\/li>\n<li><strong>PUT \/items\/:id<\/strong> \u2014 update an existing item<\/li>\n<li><strong>DELETE \/items\/:id<\/strong> \u2014 remove an item<\/li>\n<\/ul>\n<p>Each route handler receives the request and returns a JSON response.<\/p>\n<h2>Test Your API<\/h2>\n<p>Run <code>node server.js<\/code> and test with Postman or curl. Send JSON payloads with the <code>Content-Type: application\/json<\/code> header, then verify the status codes and response bodies.<\/p>\n<h2>Conclusion<\/h2>\n<p>Your REST API is ready.
