mergeHttpContext

mergeHttpContext is a utility function that combines multiple HttpContext instances into a single context, preserving the most recent values for each token.

Usage

import { mergeHttpContext } from 'ngxtension/merge-http-context';

@Injectable()
export class UsersService {
  http = inject(HttpClient);

  getUsers() {
    return this.http.get('api/users', {
      context: mergeHttpContext(withCache(), withLogResponse()),
    });
  }
}

const LOG_RESPONSE = new HttpContextToken<boolean>(() => false);

export function withLogResponse(): HttpContext {
  return new HttpContext().set(LOG_RESPONSE, true);
}

const CACHE = new HttpContextToken<boolean>(() => false);

export function withCache(): HttpContext {
  return new HttpContext().set(CACHE, true);
}
