JavaScript implementation of the WebSockets module that libp2p uses and that implements the interface-transport interface

Lead Maintainer

Jacob Heun

Description

libp2p-websockets is the WebSockets implementation compatible with libp2p.

Usage

Install

npm

> npm i libp2p-websockets

Constructor properties

const WS = require('libp2p-websockets')

const properties = {
  upgrader,
  filter
}

const ws = new WS(properties)
Name Type Description Default
upgrader Upgrader connection upgrader object with upgradeOutbound and upgradeInbound REQUIRED
filter (multiaddrs: Array<Multiaddr>) => Array<Multiaddr> override transport addresses filter Browser: DNS+WSS multiaddrs / Node.js: DNS+{WS, WSS} multiaddrs

You can create your own address filters for this transports, or rely in the filters provided.

The available filters are:

  • filters.all
    • Returns all TCP and DNS based addresses, both with ws or wss.
  • filters.dnsWss
    • Returns all DNS based addresses with wss.
  • filters.dnsWsOrWss
    • Returns all DNS based addresses, both with ws or wss.

Libp2p Usage Example

const Libp2p = require('libp2p')
const Websockets = require('libp2p-websockets')
const filters = require('libp2p-websockets/src/filters')
const MPLEX = require('libp2p-mplex')
const { NOISE } = require('libp2p-noise')

const transportKey = Websockets.prototype[Symbol.toStringTag]
const node = await Libp2p.create({
  modules: {
    transport: [Websockets],
    streamMuxer: [MPLEX],
    connEncryption: [NOISE]
  },
  config: {
    transport: {
      [transportKey]: { // Transport properties -- Libp2p upgrader is automatically added
        filter: filters.dnsWsOrWss
      }
    }
  }
})
