Mastering Angular Debugging: Essential Tips for Faster Development

As a good Angular developer, fast debugging is crucial for efficient development. Debugging helps identify issues quickly and keeps your development workflow smooth. 

In this post, I'll share essential debugging techniques and life hacks to help you debug Angular applications like a pro! 

 

• For quick debugger in we can use console.log() in typscript file.    

 

console.log('User Data:', this.userData); 

 

better visualization of objects/arrays: 

 

console.table(this.usersList); 

 

• If you want the browser to pause execution at a specific point, insert the debugger; statement in your TypeScript function. 

 

someFunction() { 

  debugger;  // Execution will pause here 

  console.log("Debugging..."); 

} 

 

• Debugging API Calls in the Network Tab 

 

• Setting Breakpoints in the DevTools Source Code of browser  

you can go find the source code like in the webpack:// under then you can debug the file. 

Any global file search use = ctrl +p and in file under search text ctrl + f 

 

 

• Debugging Angular Components in the Console 

 

  CMD => 

ng.getOwningComponent($0) 

ng.getRootComponents($0) 

ng.getDirectives($0) 

 

• Using Chrome Extensions for Debugging 

 

 

• Debugging Change Detection Issues 

 

• Using zone.js for Asynchronous Debugging
