Using Angular Augury to Debug Your Code

Augury: A powerful Angular application debugging tool

Augury is an open source tool designed for debugging and analyzing Angular 2 applications. It intuitively presents the application architecture with a tree structure, allowing developers to easily check object properties, modify in real time, view source code, set breakpoints, handle events, etc.

Augury's core advantages:

• Open source and easy to use: As a Chrome browser extension, Augury is easy to install and does not require time-consuming learning.
• Intuitive visualization: Show components and their dependencies in a tree structure to facilitate understanding of the application architecture.
• Real-time debugging: Allows real-time checking and modifying object properties in real time, and immediately observe the changes.
• Powerful debugging functions: Supports advanced debugging functions such as viewing source code, setting breakpoints, and handling events.
• Dependency injection diagram: Clearly display the dependencies between components to facilitate troubleshooting dependency injection problems.
• Routing system visualization: Intuitively display the application's routing structure, which is convenient for debugging routing-related issues.

Augury User Guide:

1. Installation of Augury: Install the Augury extension from the Chrome Web Store.
2. Start the Developer Tools: Press Ctrl Shift I (Windows/Linux) or Cmd Option I (macOS) to open the Developer Tools.
3. Switch to the Augury panel: Find and switch to the "Augury" tab in the developer tools.
4. Browse the component tree: Select the target component in the component tree, and the right panel will display the properties, dependencies and other information of the component.
5. Set breakpoints: Set breakpoints in the source code panel to pause when the program executes to a specific location for deeper debugging.
6. Check Dependency Injection: Use the "Injector Graph" function to check the dependency injection relationship of the component.
7. View routes: Use the "Routes" function to view the application's routing configuration.

Sample application:

To better understand the functions of Augury, a simple Angular application is built in the article to demonstrate the various functions of Augury. The app lists some users and allows users to edit user information.

Augury's main functional modules:

• Component View (Component View): Displays the component tree, allowing you to check and modify component properties, view source code, and set breakpoints.
• Forms: Provides detailed inspection and real-time modification of form controls.
• Dependency Injection: Intuitively display the dependency injection relationship through "Injector Graph".
• NgModules: Displays all modules and their information used in the application.
• Routes: Displays the application's routing configuration to facilitate debugging routing-related issues.

Summary:

Augury is a simple and powerful Angular application debugging tool that can significantly improve the debugging efficiency of Angular developers. Its intuitive interface and rich features make it one of the must-have tools for every Angular developer.
