Back-End Development
Back-End Development refers to the server-side of web development, focusing on the logic and database interactions that power the front-end of a website or application. In this article, we will discuss how to create a server with Express JS and Node JS to build a Rest API.
Create Server with Express JS and Node JS
Express JS is a popular web application framework for Node JS that provides a minimal and flexible set of tools for building web applications and Rest APIs. Node JS is a JavaScript runtime built on Chrome’s V8 JavaScript engine, allowing you to run JavaScript code outside the browser.
To create a server with Express JS and Node JS, you will need to install Node JS on your machine. Once Node JS is installed, you can use npm (Node Package Manager) to install Express JS by running the following command in your terminal:
npm install express
After installing Express JS, you can create a new file (e.g., server.js) and require the Express module to create a new instance of an Express application. You can then define routes, middleware, and error handling to build your Rest API.
Rest API
A Restful API (or Rest API) is an architectural style for creating web services using HTTP requests to access and manipulate data. Rest APIs are commonly used to build back-end services for web and mobile applications, enabling communication between the client and server using standard HTTP methods like GET, POST, PUT, and DELETE.
With Express JS and Node JS, you can easily create Restful APIs by defining routes that handle different HTTP methods and interact with a database or external services. You can use middleware to parse request bodies, authenticate users, and handle errors, providing a robust and scalable solution for building back-end services.
Conclusion
Back-End Development is a crucial part of web development, and creating a server with Express JS and Node JS to build a Rest API is an essential skill for back-end developers. By leveraging the power of JavaScript and the simplicity of Express JS, you can create robust and scalable back-end services for your web and mobile applications.
