NodeJs WebSocket

Publish with NodeJS

How to subscribe? see here

You can use following two ways to publish messages/events on the WebSocket Channel Rooms using NodeJS from server-side.

1. Publish with PieSocket NodeJS SDK

npm i piesocket-nodejs

Initialize PieSocket class

const PieSocket = require("piesocket-nodejs");
var piesocket = new PieSocket({
    clusterId: 'YOUR_CLUSTER_ID',
    apiKey: 'YOUR_API_KEY',
    secret: 'YOUR_API_SECRET'
});

You are ready to publish messages as many times as you wish:

piesocket.publish(roomId, data);

2. Publish with HTTP Request

Use the following code snippet to publish a message on a WebSocket Room with NodeJS.

var unirest = require('unirest');

var payload = {
    "key": "oCdCMcMPQpbvNjUIzqtvF1d2X2okWpDQj4AwARJuAgtjhzKxVEjQU6IdCjwm", //Demo key, get yours at https://piesocket.com
    "secret": "d8129f82f8dd71910aa4a7efa30a7297", //Demo secret, get yours at https://piesocket.com
    "roomId": 1,
    "message": {"event":"new-message","data":"Hello"}
}

var req = unirest('POST', 'https://CLUSTER_ID.piesocket.com/api/publish')
    .headers({
        'Content-Type': 'application/json'
    })
    .send(JSON.stringify(payload))
    .end(function(res) {
        if (res.error) throw new Error(res.error);
        console.log(res.raw_body);
    });

This sends a JSON message to WebSocket room 1, to send a string, replace "message": { "text": "Hello world!" } with "message": “Hello world!”
