This project demonstrates how to add Twitter's realtime likes functionality to your Node app with Pusher. Here's a walkthrough.

Description

The app's homepage displays a list of posts. Open the app in several different browser windows or tabs simultaneously. You'll see that liking a post in one window reflects across all windows wthout needing a page refresh.

Prerequisites

Node.js (v6.0.0 or higher)
MongoDB (v3.4.0 or higher)
A Pusher account and a Pusher app credentials

Getting started

Clone the project:

git clone https://github.com/shalvah/poster

Put your Pusher app credentials in a .env file in the project root:

PUSHER_APP_ID=your-app-id
PUSHER_APP_KEY=your-app-key
PUSHER_APP_SECRET=your-app-secret
PUSHER_APP_CLUSTER=your-app-cluster

Look for these lines of JavaScript in views/index.hbs:

var pusher = new Pusher('your-app-id', {
    cluster: 'your-app-cluster'
});

Insert your Pusher app ID and cluster in the appropriate places.

Start your MongoDB server by running mongod.

Then:

node bin/seed.js
npm start
