Correspond NPM

Correspond - A module for establishing Peer-to-peer WebRTC connections with React

This repository consists of two main packages: correspond and correspond-signaling.

correspond Is the series of React components and helpers for establishing a peer-to-peer WebRTC connection through the correspond-signaling server.

correspond-signaling Establishes a peer-to-peer WebRTC connection through WebSockets initially.

Quick start

First, Create two projects, a server-side node application that will work as the signaling layer for the WebRTC connection and a React front-end application.

Server

Add the signaling module. yarn add correspond-signaling (or npm install correspond-signaling)
Create an instance of the signaling module:

var startSignalingServer = require("correspond-signaling");
startSignalingServer(8088); // run on port 8088

Run the application node server.js (or whatever you name the server)

Client

Add correspond to your React project. yarn add correspond (or npm install correspond)
Define a code path for establishing the session as the Host (e.g. something like react/@reach router).

  import { Correspondent } from 'correspond'
  ...
  <Correspondent socketAddress={SOCKET_ADDRESS}>
    {connectionProps => <Host {...connectionProps} />}
  </Correspondent>

Define another code path for establishing a session as a client

  import { Correspondent } from 'correspond'
  ...
  <Correspondent socketAddress={SOCKET_ADDRESS}>
    {connectionProps => <Client {...connectionProps} />}
  </Correspondent>

Create Host component using the Host container component from correspond. This Host depends on the connectionProps from the Correspondent component above.

import { Host } from "correspond";
...
  <Host {...props}>
    {({
      hasSocketConnection,
      hasDataChannel,
      sendMessage,
      accessCode,
      subscribe
    }) => {
      ...
    }

Create a Client component using the Client container component from correspond. This Client depends on the connectionProps from the Correspondent component above.

import { Client } from "correspond";
...
  <ClientWrapper {...props}>
    {({
      hasDataChannel,
      sendMessage,
      subscribe,
      establishConnectionWithKey
    }) => ( /* standard component stuff using these props*/ )}
  </ClientWrapper>
