A Beginner's introduction to back-end development

Back-end development, unlike front-end development that deals with the interactive part of the web application, deals with building and maintaining the mechanism of data storage and security of the web application. Back-end technologies like node, Django and Laravel are used to design the back-end aspect in addition to data storage programmes like MongoDB and postgresql.

Attempting a beginner's challenge in the back-end development could be a bit challenging since there is no interaction with the browser.

Below is a challenge that I engaged in as a beginner in nodejs.

Challenge
Attempting to design a real time chat application using nodejs and sockets.io. sockets.io is a framework that uses a bidirectional architecture to communicate between server and client.

Step 1
The first step was to create an .html file that contains the input type form of the messenger's name and the message. While inside the script tag a socket instance is created to send message to the Express server, and also listen for incoming events.

Step 2
In the .JS file, we have created the express app and served the HTML to the server. A socket instance was created to listen to any incoming event and transmits such events to the .html.

In order to continue to practice and improve my back-end skill, I have enrolled in the HNG internship programme. It offers practical exercises and mentorship to beginners in the tech industry.
