@pulsebeam/peer v0.1.0-rc.2

@pulsebeam/peer: WebRTC Peer-to-Peer Communication SDK

Simplifies real-time application development. Defines signaling protocol for connection establishment, handling media and data transmission, and provides infrastructure.

Features

• Media & Data Support: Transmit audio, video, and/or data channels within your applications.
• Abstracted Signaling: Handles the exchange of information required to set up WebRTC connections, relieving you of low-level details.
• Automatic Reconnection: Maintains connection stability by automatically re-establishing connections when disruptions occur.
• Opt out of Peer-to-Peer: Can configure to force server-relayed communication.

Roadmap

The project is in active development, please refer to the roadmap to track our major milestones.

Status

!WARNING This SDK is currently in Developer Preview. During this phase:

• APIs are subject to breaking changes

Installation

Install and import the package using npm, deno, or yarn:

Use with npm

Add Package

npm i @pulsebeam/peer

Import symbol

import * as peer from "@pulsebeam/peer";

Use with Yarn

Add Package

yarn add @pulsebeam/peer

Import symbol

import * as peer from "@pulsebeam/peer";

Usage

Here's an example demonstrating how to use @pulsebeam/peer to establish a peer-to-peer connection:

import { Peer, createPeer } from "@pulsebeam/peer";

// Obtain an authentication token (implementation specific)
const authResponse = await fetch("/auth");
const { groupId, token } = await authResponse.json();

// Create a Peer instance
const peer = await createPeer({ token });

peer.onsession = (session) => {
  session.ontrack = ({ streams }) => console.log("New media stream:", streams);
  session.ondatachannel = (event) => console.log("Data channel:", event.channel);
  session.onconnectionstatechange = () => console.log("Connection state changed");
};

// Start Alice's availability. Connect to our signaling servers
peer.start();

// Connect to bob
const abortController = new AbortController();
await peer.connect(groupId, "bob", abortController.signal);

This example retrieves an authentication token (implementation details will vary depending on your setup), creates a Peer instance, and defines event handlers for receiving media streams, data channels, and connection state changes (optional). Finally, it starts connection attempts and connects to a specific peer identified by its ID within the group.
