TFPSockets

Simple, lightweight, event based websockets library for web and nodejs.

TFPSockets

Usage

Install

npm install --save tfpSockets

Client

Include code - Browser

<script src="TFPSocketsClient-Browser.js"> </script>

Include code - Nodejs

const TFPSocketsClient = require('TFPSockets').client

Open connection

var conn = new TFPSocketsClient("ws://localhost:1600", ["chat"])
    conn.on('connected', event => {
        console.log('connected')
       
    })

Add event listeners

conn.on('eventName', data => {
    console.log('Received event: ', data.eventName, 'with payload: ', data.payload)
})

Listener for all events

All events will be sent to `message` listener even if there is another listener sent for those events.

conn.on('message', event => {
    console.log("onMessage received event: ",event)
  })

Send Events

conn.send('eventName',{x:0,y:0})

Send Data

conn.sendData('eventName',new Uint8Array())

Client for browser is build on top of WebSocket javascript object. TFPSocketsClient provides access to base socket object via ws property and can also be initialised with a pre initialised WebSocket instance using:

var client = new TFPSocketsClient(null, null,initialisedWS)

Server

Server library is build on top of WS libary. library provides access to base WebSocket.Server object via wss proprerty for those who need more customisation.

Include

const TFPSocketsServer = require('TFPSockets').server

Create Server (using express)

const express = require('express');
const http = require('http');
const url = require('url');

const app = express();


const server = http.createServer(app);

const TFPServer = new TFPSocketsServer(server,["chat"])

server.listen(1507, function listening() {
  console.log('Listening on %d', server.address().port);
});

Listening for connections and event

TFPServer.on('connection',client => {
  client.on('testEvent', data => {
    console.log("test event payload: ", data.payload)
    client.send('testEventBack',{x:1,y:100})
  })
})

Limitations & next steps

• doesn't support binary data events - WIP
• ssl certificates setup - WIP
