wscl

Simple WebSocket wrapper with some extra features:

• auto reconnect with exponential backoff strategy
• wait connection before sending messages
• on() returns unsubscribe function
• on('message') & on('error') callback called with data and error (not event)

Lib is tiny. Its size limited to 635 bytes (with all deps, minified and brotlied).

How to use

yarn add wscl

import {Client, events} from 'wscl'

const wsc = new Client({
  url: 'wss://echo.websocket.org',
})

wsc.on(events.Open, console.log)
wsc.on(events.Close, console.log)
wsc.on(events.Message, console.log) // will be called with data not event
wsc.on(events.Error, console.log) // will be called with error not event

// you can send message before connect
wsc.send("message")

await wsc.connect()
console.log(wsc.connected)

wsc.close("reason")
