# Category: Angular Cursor Rules

## Prerequisites
- Ensure the application is running on Angular version 9 or later with Ivy enabled, as Angular DevTools requires Ivy for proper functionality.

## Installation
- Install Angular DevTools as a browser extension:
  - **Chrome**: [Angular DevTools on Chrome Web Store](https://chrome.google.com/webstore/detail/angular-devtools/ienfalfjdbdpebioblfackkekamfmbnh)
  - **Firefox**: [Angular DevTools on Firefox Add-ons](https://addons.mozilla.org/en-US/firefox/addon/angular-devtools/)

## Debugging with Angular DevTools
- **Component Tree Inspection**:
  - Open the Angular DevTools 'Components' tab to visualize the component hierarchy.
  - Select components to inspect their properties, inputs, outputs, and state.
  - Utilize the search functionality to locate specific components or directives by name.

- **State Modification**:
  - Directly edit component properties within the 'Components' tab to test and debug state changes in real-time.

- **DOM Navigation**:
  - Double-click a component in the 'Components' tab to highlight its corresponding DOM element in the browser's Elements panel.

- **Console Access**:
  - Use `$ng0` in the browser console to reference the currently selected component or directive, facilitating direct interaction and debugging.

## Profiling with Angular DevTools
- **Change Detection Profiling**:
  - Navigate to the 'Profiler' tab and start recording to capture change detection cycles.
  - Interact with the application to generate profiling data, then stop recording to analyze the results.

- **Performance Analysis**:
  - Examine the flame graph and bar chart to identify components with high rendering times.
  - Focus on optimizing components that consistently exhibit longer change detection durations.

- **Lifecycle Hooks Monitoring**:
  - Utilize the profiler to monitor the execution of lifecycle hooks and their impact on performance.

## Best Practices
- **Regular Profiling**:
  - Integrate performance profiling into the development workflow to proactively identify and address performance bottlenecks.

- **Component Optimization**:
  - Refactor components with heavy computation or complex templates into smaller, reusable parts to enhance performance.

- **Change Detection Strategy**:
  - Implement the `OnPush` change detection strategy for components where applicable to reduce unnecessary change detection cycles.

- **Keep DevTools Updated**:
  - Regularly update Angular DevTools to benefit from the latest features and improvements.
