WebRTC Tutorial in Rust+WASM !

Quick prerequisites

You will need to install cargo-make and microserver
cargo install --force cargo-make
cargo install microserver

Start Right away

You need two terminals opened in the root directory of the project.

From Terminal 1
Terminal 1 🛠 : cd ./wasm_client
Terminal 1 🛠 : cargo make build or cargo make watch (if you plan on tinkering)
Terminal 1 🚀 : cargo make serve

From Terminal 2:
Terminal 2 🔌 : cd ./signalling-server
Terminal 2 🔌 : cargo make servesignal

⚠️ Don't forget to set your own ip address for your web-socket's signalling server inside /wasm_client/src/websockets.rs

This is to be read with the following Medium Article.

Useful Terminology

• ICE : Interactive Connectivity Establishment

• SCTP : Stream Control Transmission Protocol (SCTP)

• SDP : Session Description Protocol

• STUN : Session Traversal Utilities for NAT

• NAT : Network Address Translation

• TURN : Traversal Using Relays around NAT

• Signaling: Signaling is the process of sending control information between two devices to determine the communication protocols, channels, media codecs and formats, and method of data transfer, as well as any required routing information. The most important thing to know about the signaling process for WebRTC: it is not defined in the specification. This is something that be implemented by the programmer, this project makes use of websockets to achieve this.
