I’m Learning WebRTC and Want to Make a Website Like TalkRush

I am Learning WebRTC and Want to Build a Website Like TalkRush

Hello everyone,

I am new to coding and still trying to understand how real-time chat and video chat websites work. Recently I found a website called TalkRush – Chat With Stranger, and I want to learn how something like this is created.

Here are the pages I checked:

• TalkRush Chat – Random Chat
• TalkRush Group Chat
• TalkRush Video Chat
• TalkRush Home Page

I am trying to understand how these kinds of features are made:

• Stranger chat
• Group chat
• Video chat using WebRTC
• Simple UI but working smoothly

I am learning WebRTC but honestly I am still confused about many things.

What I understood till now

• WebRTC is used for real-time video/audio.
• For signaling, something like WebSocket or Socket.io is used.
• STUN/TURN servers are needed for connecting peers.
• Frontend can be plain JavaScript also (I am still learning).

What I am not understanding clearly

• How does signaling actually work internally?
• How do two random users get connected automatically?
• How do group rooms work?
• How to handle video/audio streams properly?

My question

If anyone has made a chat website with WebRTC, can you please guide me?

1. How can a beginner create something like the TalkRush website shown above?
2. Is it better to start from scratch or use some library first?
3. Any simple explanation/tutorial for WebRTC signaling and matching users?

I want to learn and make a small project like this, but I feel stuck.

Any help will be appreciated.

Thank you.
