How can I implement logging interceptors in Angular CLI?

You can create a logging interceptor by implementing the HttpInterceptor interface in Angular. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class LoggingInterceptor implements HttpInterceptor {
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    console.log('Request URL:', req.url);
    return next.handle(req);
  }
}

Don't forget to provide this interceptor in your app module!

How do I register the interceptor in my app module?

You can register the interceptor in your app module by adding it to the providers array like this:

import { HTTP_INTERCEPTORS } from '@angular/common/http';
import { LoggingInterceptor } from './logging.interceptor';

@NgModule({
  providers: [
    { provide: HTTP_INTERCEPTORS, useClass: LoggingInterceptor, multi: true }
  ]
})
export class AppModule {}
