Retry Strategies

Introduction

Retry strategies automatically re-attempt failed HTTP requests, improving resilience.

Exponential Backoff

http.get('/api/data').pipe(
  retry({
    count: 3,
    delay: (error, retryCount) => timer(Math.pow(2, retryCount) * 1000)
  }),
  catchError(err => of(fallbackData))
)

Summary

Retry with exponential backoff is the standard pattern for resilient HTTP calls.”
