The Best Way To Write Your Express.JS Server
Before we break down tips that add up to writing the best server, let’s discuss a bit about express.js.
Node.js has a core module known as ‘http’ to create an HTTP server and handle requests.
In this example, we imported the http module and created a server and the server takes a req and res parameters where a request is used to take input from a user and a response is used to send response data back to the user who sent a request to the server. The server listens on port 3000 and responds with “node.js is cool!” for every request. So when the user enters http://localhost:3000, “node.js is cool!!” is what they get a response.
So why not use the http module and what is the need for other frameworks? Frameworks like express.js are built on top of node.js to facilitate an easy and fast development process. It makes it easy to define route paths, and middleware and create structure. So the same code can be re-written in express.js like this:-So as you can see express.js provides a simple way to define routes for your application. You just need to add `app.method_name` and as easy as that you can add routes.
There are multiple ways to create your express.js server, write your routes, and structure your functions. But these tips can help you build a better server and code structure.1. Combine http module with express.js when you create your server
This is a fantastic way to create a server because
1.1) HTTPS Support
This can be easily extended to support HTTPS by importing the HTTP module. You can use the same server setup for both HTTP and HTTPS by providing the appropriate SSL/TLS certificates. This flexibility allows you to serve your application securely over HTTPS when needed.
