A step-by-step guide to building a chat system in 5 minutes

More than 3 Billion people around the world are using messaging apps in their day-to-day lives. Most of the time they use WhatsApp and Facebook for their personal communication. But the question here is, 

Is WhatsApp and Facebook reliable for business communication?

While the parent company of these two messaging giants is facing allegations of data breaches, most experts advise businesses to build their own chat apps with custom security. 

But, how to build your encrypted chat system? Is it easy?

Keep your worries away! This article will cover everything about building your own chat system, its prerequisites and the complete development process before you get started with your project.  

What Is A Chat System?

The chat system is a chat app that uses the TCP/ IP ( Transmission Control Protocol/ Internet Protocol) and follows the client-server model to deliver the messages smoothly between clients. Some popular examples of a chat system are Whatsapp, Facebook Messenger, Discord, Google Chat, and Line.

How Does A Chat System Work?

When you launch your chat app, the following processes will take place for each user action. Let me break them down:

Step 1: User Registration and Authentication

  • First, a user registers into your messaging app by filling in details like username, email and password.  
  • This is where you need to implement secure authentication systems to verify user identity.  You can use technologies like OAuth, JWT (JSON Web Tokens), or traditional username/password validation.

Step 2: Establishing a Connection

  • Once users start using your chat app, it starts connecting to the chat server.
  • During this stage, the chat meta data may be exposed to risks like data theft and malware attacks. To ensure that the conversations are safe, you need to use AES-128 protocol and SSL certification.

Step 3: User Presence and Status

  • Right when the user enters your app, the server starts maintaining a record of users’ online/offline status and availability.
  • This is where an online presence indicator feature will help your app update and broadcast user presence status to their contacts.

Step 5. Message Routing

  • Now, you may send 1:1 messages or chat with multiple users. This is where the server receives messages and identifies the recipient based on their unique identifier.
  • Make sure you implement a logic to send and receive one-on-one messaging and group chat routing.

Step 6. Real-Time Communication

  • You can use WebSocket or a similar technology to establish a persistent, bidirectional connection between the client and server.
  • This enables real-time communication within your app at the lowest possible latency.

Step 7. Message Delivery and Receipt

  • Next you need to implement message delivery and receipt confirmation in your chat system.
  • Optionally, you can include read receipts to inform the sender when the recipient has read the message.

Step 8. Message Storage

  • When it comes to accessing the messages, decide whether messages will be stored temporarily for real-time delivery or persistently for future retrieval.
  • Implement a database system to store messages securely, associating them with the sender, recipient, and timestamp.

Step 9. Notifications

  • Develop a notification system to inform users of new messages, friend requests, or other relevant events.
  • You can also keep your users informed when they are not active on your app, through notifications on their mobile apps.

Step 10. Logging Out

  • When the user logs out from your app, you need to make sure that you implement a secure logout mechanism. So that the client disconnects from the server and updates the user’s presence status.

Step 11. Scaling and Performance

  • Keep an eye on the scalability of your chat system. You can maintain load balancing and scalable infrastructure to handle increasing numbers of users and messages, as your app grows.

12. Testing and Quality Assurance

  • Conduct thorough testing of the app, including unit testing, integration testing, and user acceptance testing.

Pay special attention to security testing to identify and address potential vulnerabilities in advance to avoid threat to your brand integrity and reputation.
