Component Purpose

The listenerService is designed to manage event listeners within the scope of an AngularJS
application. It helps track and clean up event listeners when a scope is destroyed, preventing
memory leaks and ensuring efficient resource management.

---

Component Outcomes and Interactions

1. The service allows different parts of an application to register event listeners in a structured
   way.

2. When a scope is destroyed (e.g., navigating away and removing the component from the DOM), the
   service ensures that all associated event listeners are cleaned up to avoid memory leaks.

3. The listeners are primarily used to watch changes in data (such as with the
   progress-burndown-chart.coffee) and update the UI accordingly.

Current Uses

• group-member-list.coffee
• group-selector.coffee
• dashboard.coffee
• task-dashboard.coffee
• tasks.coffee
• unit-task-list.coffee
• progress-burndown-chart.coffee

Component Migration Plan

As this is a non visual service, the migration will only require:

1. Create new listener.service.ts file.

2. Update imports in doubtfire-angular.module.ts and doubtfire-angularjs.module.ts files.

3. Downgrade the service so it is usable via angularJs components.

4. Migrate service logic to typescript and angular 17 compatibility.

5. Update call instances from angularJs components to handle lifecyle. (This will not be required
   angular17 components.)

6. Test implementation via manual testing and console logging.

Hello Lachlan, just went through your component review.

1. Component Name and file has been mentioned properly
2. Component Purpose, Outcomes and Interactions have been described briefly
3. Also well Structured Migration Plan
   Template has been structured properly, I approve this Component Review. Now you can proceed with your migration, all the best.
   One thing I would like to mention here is if you want to merge any commit merge it into 8.0.x instead of main

Hi Lachlan, I completed the migration for the listenerService component. It has been successfully downgraded and tested in AngularJS. Everything seems to be working as expected! Good job!
