Introduction:
Express is a popular and widely-used web application framework for Node.js, designed to simplify the process of building server-side applications. In this tutorial, we will walk you through setting up a local server using Node.js and Express. By the end of this tutorial, you will have a basic understanding of how to create a local server using Express and handle HTTP requests and responses.

Requirements:

• Node.js installed on your machine
• A code editor, such as Visual Studio Code

Step 1: Create a new project directory First, create a new directory for your project.

Step 2: Install Express Next, install the Express framework by running the following command:

npm install express

Step 4: Create the server Create a new file in your project directory called server.js and open it in your code editor. Add the following code to create a basic Express server:

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

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

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

In this code, we import the Express module, create a new Express application, and define a route for the root path (“/”). The server listens for incoming HTTP requests and responds with a “Hello, World!” message.

Step 5: Start the server To start the server, run the following command in your terminal:

node server.js

You should see the following message indicating that the server is running:

Server is running on http://localhost:3000

Step 6: Test your server Open your web browser and visit http://localhost:3000. You should see the “Hello, World!” message displayed in your browser.

Conclusion:
In this tutorial, we demonstrated how to create a local server using Node.js and Express. You can now use this knowledge to build more complex server-side applications and APIs. As you continue to explore Express, you can learn about advanced features like middleware, routing, and templating, which will further enhance your server-side development skills.
