router.get(‘/’, async (req, res) => {
const items = await Item.find();
res.json(items);
});
router.post(‘/’, async (req, res) => {
const newItem = new Item(req.body);
await newItem.save();
res.status(201).json(newItem);
});
module.exports = router;
Integrating Routes into the Server
Next, we need to integrate our routes into the server. Open server.js and add the following code:
const itemRoutes = require(‘./routes/itemRoutes’);
app.use(‘/api/items’, itemRoutes);
Testing the API
To test our API, we can use tools like Postman or Insomnia. Start your server by running:
- node server.js – This will start your server.
Once your server is running, you can test the following endpoints:
- GET /api/items – Retrieve all items.
- POST /api/items – Create a new item.
Conclusion
Congratulations! You have successfully built a RESTful API with Node.js. You can now expand this API by adding more features, such as authentication, validation, and more complex data relationships.

Building a RESTful API with Node.js can be a rewarding experience, allowing you to create powerful applications. This tutorial will guide you through the process step-by-step.
Prerequisites
Before we start, make sure you have the following:
- Node.js installed on your machine.
- A code editor, such as Visual Studio Code.
- Basic knowledge of JavaScript and Node.js.
Setting Up the Project
To begin, let’s set up our project directory and initialize a new Node.js application.
Open your terminal and run the following commands:
- mkdir my-api – Create a new directory for your project.
- cd my-api – Navigate into your project directory.
- npm init -y – Initialize a new Node.js project.
Installing Dependencies
Next, we need to install some essential packages for our RESTful API.
- npm install express – A web framework for Node.js.
- npm install body-parser – Middleware to handle JSON request bodies.
- npm install mongoose – An ODM for MongoDB.
Creating the Server
Now it’s time to create our server. Create a file named server.js in your project directory.
Open server.js and add the following code:
const express = require(‘express’);
const bodyParser = require(‘body-parser’);
const mongoose = require(‘mongoose’);
const app = express();
app.use(bodyParser.json());
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
Connecting to MongoDB
To store our data, we will connect to a MongoDB database. You can use MongoDB Atlas for a cloud-based solution or run MongoDB locally.
Add the following code to connect to your MongoDB instance:
mongoose.connect(‘mongodb://localhost:27017/mydatabase’, {
useNewUrlParser: true,
useUnifiedTopology: true
});
Defining the Model
Next, we need to define a model for our data. Create a new folder named models and add a file named Item.js.
In Item.js, add the following code:
const mongoose = require(‘mongoose’);
const itemSchema = new mongoose.Schema({
name: { type: String, required: true },
quantity: { type: Number, required: true }
});
module.exports = mongoose.model(‘Item’, itemSchema);
Creating Routes
Now we will create routes to handle our API requests. Create a new folder named routes and add a file named itemRoutes.js.
In itemRoutes.js, add the following code:
router.get(‘/’, async (req, res) => {
const items = await Item.find();
res.json(items);
});
router.post(‘/’, async (req, res) => {
const newItem = new Item(req.body);
await newItem.save();
res.status(201).json(newItem);
});
module.exports = router;
Integrating Routes into the Server
Next, we need to integrate our routes into the server. Open server.js and add the following code:
const itemRoutes = require(‘./routes/itemRoutes’);
app.use(‘/api/items’, itemRoutes);
Testing the API
To test our API, we can use tools like Postman or Insomnia. Start your server by running:
- node server.js – This will start your server.
Once your server is running, you can test the following endpoints:
- GET /api/items – Retrieve all items.
- POST /api/items – Create a new item.
Conclusion
Congratulations! You have successfully built a RESTful API with Node.js. You can now expand this API by adding more features, such as authentication, validation, and more complex data relationships.
const express = require(‘express’);
const router = express.Router();
const Item = require(‘../models/Item’);
router.get(‘/’, async (req, res) => {
const items = await Item.find();
res.json(items);
});
router.post(‘/’, async (req, res) => {
const newItem = new Item(req.body);
await newItem.save();
res.status(201).json(newItem);
});
module.exports = router;
