Publisher-Subscriber model (implementation)

Every "user" has their own list of topics they follow i.e. a list of topics to which they subscribed. When one of the publishers writes a book/blog, notify the users who subscribed to the topic. Optionally add/remove any number of:

1. Users(Subscribers)
2. Publishers
3. Topics

Usage

The application has 3 dependencies:

• Bootstrap: Front end framework
• jQuery: JavaScript library
• Mustache: Logicless template synatx

Execute the following command to include all dependencies from package.JSON:

npm install

Open index.html and start entering the publishers and subscriber details.

Subscribers can now subscribe to different topics.

Subscribers recieve notifications when Publishers publish content on their subscribed topics

NOTE: This is just using client side javaScript. So a page refresh will erase all the data entered. But simply writing to a JSON file when modifying a publisher/subscriber will get you a fully functional application.
