This a test issue to help get familiar with the workings of the project.
Need to add a button to the left-hand nav in the viewer that, when pressed, turns the background of the Navigation to red. Pressing it again would return the nav back to normal. Also need to log when the nav is set to the red alert state and returned back to the normal state.
Here would be the steps to implement this:
Add a new event handler to NavStore to listen to nav:redAlert. The payload of the event should include a boolean to indicate if red alert is on or off. This event handler should call APIUtil.postEvent to send a nav:redAlert event to the server.
Modify the state of NavStore to include a new redAlert property holding a boolean if red alert is enabled or not.
Add a new method to NavUtil called setRedAlert to fire the nav:redAlert event. The method should take a boolean to indicate if red alert should be enabled or not.
Add a button to the nav component. Clicking this should call the NavUtil.setRedAlert method.
Add a query method to NavUtil - isRedAlertEnabled - that will return a boolean to indicate if red alert is enabled or not
Add two new classes in the nav component - is-red-alert and is-not-red-alert. The nav component should use the NavUtil.isRedAlertEnabled method to figure out which class to apply to the element.
Add a is-red-alert style to the nav component scss file which turns the background of the nav red.
