Module

In the previous articles, we've learned to export injectables through modules. You might note that to set up an HTTP server, createHttpModule is called, which returns a module that manages HTTP traffics for you.

You might also note that the application entry point is also a module.

The concept of the module takes an important roles in SenseJS. It's designed to do the following job for your application:

• Provide entry points for your application.

• Export injectables for other modules and components to use.

• Initialize and de-initialize components and I/O resources, such as creating database connections and establishing HTTP listeners.

We'll discuss these topics in this chapter.
