WebRTC 2022 Practical Course. Create Video Chat Application
Learn WebRTC by creating project with vanilla JavaScript. Only basic JavaScript knowledge is required. We will go through all of the steps to create application with direct calls where you can establish connection between two users by passing his personal code or you can just connect with the stranger like in omegle or talkwithstranger web apps. We will write own WebRTC implementation to show how easily you can develop WebRTC application.
More
We will not use any framework for our front-end so you do not need to have any experience with frameworks(React, Vue.js, Angular). We will use also Socket.IO as our signaling server for our application. After this course you will be able to create own application which will be using WebRTC. It does not matter if that will be the realtime communication game or video chat. You will know the process how to establish connection between two peers.
In our application we will use:
WebRTC
JavaScript
Socket.IO
Express.js
Node.js
Vanilla JavaScript to create front-end of our application
We will focus on things related with WebRTC. Also you will get a knowledge how you can use Socket.IO as your websocket server.
App creating proccess:
Prepare environment
Build frontend of our application with vanilla JavaScript
Connect with Socket.IO
Add our own WebRTC implementation for calls
Add WebRTC data channels for chat functionality
Add recording possibility
Add possibility to connect with the strangers
I hope you will enjoy the course and after finishing it you will feel confident to start preparing and adjusting your own WebRTC implementation.
