@superhero/websocket NPM

Websocket

Licence: MIT

A server/client bundle setup to solve some personal issues I have with other solutions out there.

Install

npm install @superhero/websocket

...or just set the dependency in your package.json file:

{
  "dependencies":
  {
    "@superhero/websocket": "*"
  }
}

Browser › Example

`server.js`

const Websocket = require('@superhero/websocket')
const options   = { debug:true }
const websocket = new Websocket(options)

// listen on port 80
websocket.server.listen({ port:80 })

websocket.events.on('HelloWorld', (ctx, dto) =>
{
  // dto == { 'I':'am','now':'connected' }
  ctx.emit('sup m8', { 'this':'is','the':'response' })
})

websocket.events.on('¯|_(ツ)_/¯', (ctx, dto) =>
{
  // dto == { 'also':'works' }

  // headers is an object of the request headers sent when connection was
  // established
  console.log(ctx.headers)

  // client ip
  console.log(ctx.socket.remoteAddress)

  // ip family (IPv4 or IPv6)
  console.log(ctx.socket.remoteFamily)

  // numeric representation of the remote port..
  console.log(ctx.socket.remotePort)
})

function(client)
{
  var socket = client(
  {
    host  : 'localhost',
    debug : true
  })
  .on('sup m8', function(dto)
  {
    // dto == { 'this':'is','the':'response' }
    socket.emit('¯|_(ツ)_/¯', { 'also':'works' })
  })
  .connected(function(socket2)
  {
    // `socket` === `socket2`
    // socket2 is however returned through a promise that the socket is
    // connected. attaching listeners does not need this promise, emitting
    // messages however needs a connection to send to.

    // example
    socket2.emit('HelloWorld', { 'I':'am','now':'connected' })
  })
})

Server › Example

The module has both a server and a client. So you can use the module for a server to server connection, for what ever reason you now want to do that...
