Node.js Project Setup

Setting up a Node.js project is simple and sets the stage for building powerful web applications. Here’s how to get started:

1. Install Node.js: Download and install Node.js from Node.js, which includes npm.

2. Initialize Project: Run npm init in your project directory to create a package.json file.

3. Install Dependencies: Use npm install express to add Express.js, a popular Node.js framework.

4. Write Code: Create an app.js file with your application logic.

5. Run Application: Execute node app.js to start your server.

Here’s a sample Express.js server:

const express = require('express');
const app = express();
const port = 3000;

app.get('/', (req, res) => {
  res.send('Hello, Node.js World!');
});

app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}`);
});

This code creates a basic server, demonstrating Node.js’s simplicity. Use nodemon for development to auto-restart on changes, available via npm install -g nodemon.

Node.js API with Postman

Testing Node.js APIs with Postman is essential for ensuring functionality. Postman allows developers to send HTTP requests and inspect responses, streamlining API development. Here’s how to create and test an API:

1. Create an API: Use Express.js to define endpoints. For example:

app.get('/api/users', (req, res) => {
  res.json([{ id: 1, name: 'John Doe' }]);
});

2. Test with Postman: Download Postman from Postman. Create a new request, set the method to GET, enter http://localhost:3000/api/users, and send. You’ll see the JSON response.

Postman supports saving requests, creating collections, and automating tests, making it ideal for testing APIs in projects like Strapi or KeystoneJS.

University Projects Using Node.js

Node.js’s versatility makes it perfect for university applications. Below are five project ideas, each with a detailed explanation of how Node.js is used.

1. University Course Management System
