Modules: Injector

Methods

---

getValue(key)

Retrieve a stored value

The benefit of using this, instead of directly requiring a global file, is that you remove the hard link between them. Stored values are configured in a single place, so dependencies can be swapped out easily. Also, when requiring global modules, you have no control over the 'construction' time.

Parameters:

Name	Type	Description
key	string	Use a key from app/data/Injectables.js

Source:

• app/util/injector.js, line 27

Returns:

The stored value

Type

any

---

setValue(key, value)

Save a value under a key for later use.

This is used as a way to store and access global dependencies, without hard references to specific files at the place they are used. This gives the option to swap out the dependencies with other in a single place, without affecting other code. It's a very basic form of Dependency Injection.

Currently the values are set in the app/util/setupInjects.js function that is called when bootstrapping the app.

Parameters:

Name	Type	Description
key	string	Use a key from app/data/Injectables.js
value	any	The value to store
