wretch

A tiny (~1.8KB g-zipped) wrapper around the Fetch API with an intuitive, chainable syntax. v3.0.8 (latest) is actively maintained and supports modern browsers, Node.js 22+, Deno, and Bun. Key differentiators: immutable API (cloning for reuse), automatic JSON serialization/deserialization, error handling via status-specific handlers (notFound, internalError, etc.), addon/middleware system, and full TypeScript types. Compared to alternatives like ky or axios, wretch is lighter and focuses on a minimal, functional style.
