Reactive Programming with RxJS

Client Server Communication in Node.js

Explore how to build real-time client-server communication in Node.js using WebSocket and RxJS. Understand how to connect with the Twitter API, create a WebSocket server, and handle message passing between clients and server to update your dashboard dynamically.

We'll cover the following...

Now, we’re ready to start building our application. First, let’s create a new file called index.js inside the tweet_stream folder to load the modules we’ll use:

Javascript (babel-node)
var WebSocketServer = require('ws').Server; 
var Twit = require('twit');
var Rx = require('rx');

To use the Twitter API, we need to request a consumer key and an access token on the Twitter Developer Website. Once we have that, we will create a new Twit object with a configuration object, like this:

Javascript (babel-node)
var T = new Twit({
    consumer_key: 'rFhfB5hFlth0BHC7iqQkEtTyw',
    consumer_secret: 'zcrXEM1jiOdKyiFFlGYFAOo43Hsz383i0cdHYYWqBXTBoVAr1x', 
    access_token: '14343133-nlxZbtLuTEwgAlaLsmfrr3D4QAoiV2fa6xXUVEwW9', 
    access_token_secret: '57Dr99wECljyyQ9tViJWz0H3obNG3V4cr5Lix9sQBXju1'
});

Now, we can create the onConnect function, which will do all the ...
