Package Exports

libp2p-webrtc-star
libp2p-webrtc-star/src/sig-server

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (libp2p-webrtc-star) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

js-libp2p-webrtc-star

libp2p WebRTC transport that includes a discovery mechanism provided by the signalling-star

Description

libp2p-webrtc-star is one of the WebRTC transports available for libp2p. `libp2p-webrtc-star incorporates both a transport and a discovery service that is facilitated by the signalling server, also part of this module.

Note: This module uses pull-streams for all stream based interfaces.

Usage

Installation

> npm install libp2p-webrtc-star

API

Signalling server

libp2p-webrtc-star comes with its own signalling server, used for peers to handshake their signalling data and establish a connection. You can install it in your machine by installing the module globally:

> npm install --global libp2p-webrtc-star

This will expose a star-sig cli tool. To spawn a server do:

> star-signal --port=9090 --host=127.0.0.1

Defaults:

port - 13579
host - '0.0.0.0'

Hosted Signalling Server

We host a signalling server at star-signal.cloud.ipfs.team that can be used for practical demos and experimentation, it should not be used for apps in production. A libp2p-webrtc-star address, using the signalling server we provide, looks like:

/libp2p-webrtc-star/dns4/star-signal.cloud.ipfs.team/wss/ipfs/<your-peer-id>

Note: The address above indicates WebSockets Secure, which can be accessed from both http and https.

This module uses `pull-streams`

We expose a streaming interface based on pull-streams, rather then on the Node.js core streams implementation (aka Node.js streams). pull-streams offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about why we did this, see the discussion at this issue.

You can learn more about pull-streams at:

Converting `pull-streams` to Node.js Streams

If you are a Node.js streams user, you can convert a pull-stream to a Node.js stream using the module pull-stream-to-stream, giving you an instance of a Node.js stream that is linked to the pull-stream. For example:

const pullToStream = require('pull-stream-to-stream')

const nodeStreamInstance = pullToStream(pullStreamInstance)
// nodeStreamInstance is an instance of a Node.js Stream
