Adds circuit breakers and request deduplication to native fetch via a plugin system.

Strengths
  • •Plugin lifecycle API allows tree-shaking optional features like circuit breakers.
  • •Wraps any fetch-compatible implementation, including framework-specific handlers for SSR.
  • •Zero runtime dependencies keeps the bundle size minimal for core features.
Weaknesses
  • •Crowded category with established players like Ky already solving fetch reliability.
  • •Deduplication logic requires careful TTL management to avoid stale data issues.

Post Description

ffetch v5 is out

ffetch is a TypeScript-first fetch client focused on production reliability. Core functionality includes: - timeouts (global and per-request) - retries with exponential backoff + jitter - lifecycle hooks (before/after/onError) - pending request monitoring - per-request overrides - optional throwOnHttpError

v5 introduces a public plugin lifecycle API plus first-party plugins for: - circuit breaker - in-flight request deduplication (with optional ttl/sweepInterval cleanup)

It can wrap native fetch or any fetch-compatible implementation (undici, node-fetch, framework fetch handlers).
