Retry and Loading Indicators

Implement retries and global spinners.

Two cross-cutting concerns

Interceptors are perfect for two app-wide behaviors: automatically retrying failed requests, and tracking a global loading state while any request is in flight.

Retrying with retry

Pipe retry after next(req) to re-attempt transient failures.

import { retry } from 'rxjs';

export const retryInterceptor: HttpInterceptorFn = (req, next) =>
  next(req).pipe(retry(2));
