Title: My First Day with Express.js: Creating a Server and Understanding Backend Architecture

Hey Hashnode community! 👋 Today, I delved into the world of Express.js, and what an exciting journey it has been! In this blog post, I'll share my experiences and learnings from my first day with Express.js, including how to create a server, using nodemon, and understanding the backend architecture of the web.

Creating a Server with Express.js

Express.js makes creating a server incredibly straightforward. With just a few lines of code, I was able to set up a basic server that can handle requests and responses. Here's a snippet of how simple it is to create a server using Express:

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

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

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Using Nodemon for Development

One of the tools that has already proven invaluable is nodemon. Nodemon is a utility that monitors changes in your Node.js application and automatically restarts the server when changes are detected. This saves a lot of time and hassle during development, as I can focus on writing code without worrying about manually restarting the server.

Understanding Backend Architecture

As I delved deeper into Express.js, I gained a better understanding of the backend architecture of the web. I learned about how requests flow through different layers of the server, from the client to the router to the controller, and finally to the database. Understanding this flow is crucial for building efficient and scalable web applications.

Conclusion

Overall, my first day with Express.js has been incredibly rewarding. I've learned how to create a server, use nodemon for automatic server restarts, and gained insights into the backend architecture of the web. I can't wait to continue exploring Express.js and deepen my understanding of backend development.
