Basic Usage

This Page


If you are new to pubsub, you will likely want to start with Basic Usage. If you want a quick start, jump the Quick Start section.

If you develop an application that uses pubsub, whether it is prototype or production quality code, if it is more than just an experiment you will find that it can become tedious to debug. This is because the decouping can make the link between causes and effects challenging to identify. Also, you need better control over error handling, and more maintainability via documentation of message structure. This is when you turn to the Advanced Usage section.
