Node and Phoenix Channels

I’ve been working with a Raspi lately and needed to connect it to my Phoenix app. After talking with chrismccord he showed me it was easier than I thought. See below.

Things you’ll need:

• websocket - For websocket transport.
• Phoenix.JS
• babel - For transpiling the ES6 phoenix.js file.

Once you have everything above you can just throw it in your node app just like so:

import {Socket} from "./phoenix.js"
var socket = new Socket("ws://127.0.0.1:4000/socket", {transport: require('websocket').w3cwebsocket})

socket.connect();
let channel = socket.channel("raspis:lobby");

channel.join()
  .receive("ok", resp => {
    console.log("Boom!")
  })
  .receive("error", reason => console.log(`Error joining channel: ${reason}`))

To see how to use the Phoenix.JS library head over to http://www.phoenixframework.org/docs/channels

That’s about it. Simple right?
