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).
