How to debug Angular 16 application in Chrome

Debugging Angular 16 applications in Chrome can be a straightforward process if you know the right tools and techniques. In this article, we will walk through the steps to debug an Angular 16 application using Chrome’s developer tools.

Step 1: Open your Angular 16 application in Chrome

First, open your Angular 16 application in the Chrome browser. Make sure that the application is running in your development environment.

Step 2: Open Chrome Developer Tools

To access Chrome Developer Tools, you can simply right-click on any element of your web page and select “Inspect” from the context menu. Alternatively, you can use the keyboard shortcut – Ctrl+Shift+I (Cmd+Option+I on Mac).

Step 3: Navigate to the Sources tab

Once Chrome Developer Tools are open, navigate to the Sources tab. Here, you will find your application’s source code organized in a directory structure. You can browse through the files and debug your application code from here.

Step 4: Set breakpoints

Set breakpoints in your Angular 16 application code by clicking on the line number in the source file. This will pause the execution of your application at the specified line, allowing you to inspect variables, step through code, and understand the flow of your application’s logic.

Step 5: Use the Console tab

The Console tab in Chrome Developer Tools allows you to log messages and inspect variables in real-time. Use console.log() statements to output values to the console, or interact with your application’s code directly from the console.

Step 6: Utilize the Network tab

The Network tab can be helpful in debugging issues related to AJAX requests, API calls, or other network-related activities in your Angular 16 application. You can monitor network activity, view response data, and analyze the performance of your application’s network requests.

Step 7: Explore the Performance tab

The Performance tab in Chrome Developer Tools can be used to analyze the runtime performance of your Angular 16 application. You can record and analyze performance profiles, understand where your application is spending its time, and identify opportunities for optimization.

Conclusion

Debugging Angular 16 applications in Chrome is an essential skill for every Angular developer. By following the steps outlined in this article, you can effectively troubleshoot and debug issues in your Angular 16 application, leading to a smoother development process and higher quality code.
