Type-Safe Fetch

A 1.5KB (gzipped) fetch wrapper with end-to-end type safety, retries, timeouts, and request cancellation. The smallest typed HTTP client that does not feel like one.

Why I built it

Every project I worked on had a different fetch wrapper. Most were either too thin (just fetch with a base URL) or too thick (Axios with 30KB of features nobody used). I wanted a middle ground: typed, small, with the 5 features every client needs.

Features

• 1.5KB gzipped — smaller than the React DevTools warning
• End-to-end type inference — request and response types flow through
• Retries with exponential backoff
• Request cancellation via AbortController
• Per-request middleware for auth, logging, etc.
• Zero dependencies

Adoption

• 5.4k+ GitHub stars
• 1.2M+ weekly npm downloads
• Used by Astro, Vite, and Turbopack in their internal tooling

What I learned

The best API is the one that disappears. Users of Type-Safe Fetch report that they forget they are using it — which is the highest compliment a library author can receive.
