I'm going to be writing about a back-end problem I solved and give an overview of the step-by-step approach I took to solving that problem.

Quite recently while working on implementing a messaging system and I faced an issue of making it a real-time communication system.

The Challenge

The primary challenge was to create a messaging system that supports real-time communication between users. The requirements include having real-time updates meaning messages should appear instantly without the need for refreshing the page.

Step-by-Step Solution

Step 1: Choosing Appropriate Technologies
To build the real-time chat functionality, I opted for the following technologies
- NodeJs with Socket.IO for the server-side real-time communication.
- MongoDB for persistent storage of the messages.

Step 2: Setting-up the server
I then set-up a server with NodeJs and socket.io

Step 3: Implementing the logic to handle the real-time communication
Created 4 different events for this namely;
Connection event which is triggered whenever a client connects to the server
JoinRoon event which will allow user to join specific chat rooms
Chatmessage event which will handle incoming chats
disconnect event which is triggered when the user disconnects from the server

Step 4: Creating a persistent storage for the Messages
To ensure messages are not lost and can be retrieved later, I used MongoDB for persistent storage.

Building this real-time chat application involved careful consideration of technologies and architecture and by leveraging NodeJs and Socket.io I was able to implement a messaging system that met my requirements.

I'm a backend developer that loves building good and efficient systems. Being a problem solver, I love to learn new things and ways of doing things. And recently got accepted into an internship of an organization known as HNG and I know this internship is an opportunity for me to grow my skills as a developer by working on real-world projects, learning and gathering knowledge from experts in the field.
So I really am super excited to be part of this internship which promises to be a wonderful journey. You can learn more about this internship here on https://hng.tech/internship or here https://hng.tech/hire.
I really look forward to being one of the few to complete this internship so Wish me luck in my endeavour.
