Light

This was my very first attempt at coding. I know it's filled with lots of shit, but I just don't want to erase my journey. Maybe one day I'll come back and refactor it... but for now, it stays as a testament to how far I've come.

Light is a community-oriented instant messaging platform inspired by Discord's design. It allows members to create servers and communicate in channel of each server freely via messages, video, and audio.

Main Freatures

• Use Django as server framework.
• Use Django Channels as support of WebSocket (ASGI) to achieve real-time chat.
• Use WebRTC to achieve voice and video chat.
• Deploy the website by Docker.
• Store static files and uploaded media from user by AWS S3 and speed up distribution of static files by CloudFront.
• Authenticate user with JSON Web Token.
• Use Django ORM with AWS RDS for MySQL and normalize database in 3NF.
• Use unit tests to ensure the correctness and robustness.
