Improvement ideas

Although I have many ideas in mind, due to the urgency of the project at the company and limited time, I could only create a very simple chat app.

Here are some ideas to further develop this app

• Add message storage in the database (Key-value database like Redis or SQL database)
• Implement file sharing capabilities
• Add support for multimedia messages (images, videos)
• Implement push notifications for new messages (notifications service like Firebase)
• Improve scalability to handle more users and messages
• Ensure reliability with fault-tolerant mechanisms
• Enhance security with better encryption and data protection

Acknowledgements

I would like to express my gratitude to Mr. Hau for organizing and teaching the Golang course. I have learned a lot of basic concepts from Golang and applied some of them to this project. I hope he succeeds in his future courses. TYSM!
