Constructor properties

import { createLibp2pNode } from 'libp2p'
import { webSockets } from '@libp2p/webrtc-direct'

const node = await createLibp2p({
  transports: [
    webSockets()
  ]
  //... other config
})
await node.start()
await node.dial('/ip4/127.0.0.1/tcp/9090/ws')

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

import { createLibp2pNode } from 'libp2p'
import { websockets } from '@libp2p/websockets'
import filters from '@libp2p/websockets/filters'
import { mplex } from '@libp2p/mplex'
import { noise } from '@libp2p/noise'

const transportKey = Websockets.prototype[Symbol.toStringTag]
const node = await Libp2p.create({
  transport: [
    websockets({
      // connect to all sockets, even insecure ones
      filters: filters.all
    })
  ],
  streamMuxers: [
    mplex()
  ],
  connectionEncryption: [
    noise()
  ]
})
