Feature Toggle Manager

The feature toggle manager reads statuses from a variable called window.sessionFeatureToggles.

Static Methods

hasFeature()

Use this method whenever a feature toggle switch needs to happen in the code.

/**
  * Check if a particular feature toggle is turned on.
  * Returns a boolean.
  */
FeatureToggleManager.HasFeature('some_amazing_feature');

Instantiated Methods

Console Toggle View

In order to activate a method which will allow users to issue a console command to see which feature toggles are activated, you will need to get an instance of the feature toggle manager.

Get an instance of the feature toggle manager:

const myFeatureToggleManager = FeatureToggleManager.Instance;

Then, users can simply enter a command in the console to get output similar to the following:

> window.showFeatures()

feature_toggle_x ()
feature_toggle_y (✓)
feature_toggle_z ()

GUI Toggle View

To provide a graphical user interface to users, you will need an instance of FeatureToggleDisplayPanel:

const myFeatureToggleManager = FeatureToggleManager.Instance,
      availableToggles = myFeatureToggleManager.Toggles,
      displayPanel = myFeatureToggleManager.CreateDisplayPanel(new FeatureToggleDisplayPanel(availableToggles));

// displayPanel will be a div element containing the user interface.

This is a barebones user interface. The consumer will need to make the styling decisions.
