Constructor properties

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

const node = await createLibp2p({
transports: [

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
