How to Do Angular Side Debugging Part 1
Add debugger; statement to your code: In your component's TypeScript code, you can add the debugger; statement to create a breakpoint. When the application runs in the browser and reaches this line of code, the browser's developer tools will pause execution, allowing you to inspect the state of your application.
Here's an example of how you can use debugger; in an Angular component:
typescript
Copy code
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'Angular App';
constructor() {
debugger; // add breakpoint here
}
}
2. Start your application in debugging mode: To start your application in debugging mode, you can use the --inspect flag when running ng serve. For example:
bash
Copy code
ng serve --inspect
This will start your application and open the browser's developer tools in debugging mode.
3. Inspect your Angular code: Once your application is running and the developer tools are open, you can navigate to the 'Sources' tab in the developer tools to find your Angular application's code. Here, you can set breakpoints by clicking next to the line number in the source code, and you can inspect the values of variables using the 'Scope' pane in the developer tools.
It's important to note that the debugging experience with Angular can be different compared to debugging regular JavaScript code. This is because Angular is a framework built on top of JavaScript, and its components and services are compiled to JavaScript at runtime. As a result, the code you're writing and debugging might not be exactly the same as the code that's running in the browser.
To improve the debugging experience with Angular, consider using the 'Blackboxing' feature in the developer tools. This feature allows you to ignore specific files or folders when debugging, so you can focus on your own code instead of the compiled Angular code.
