Wretch

A tiny (~1.8KB gzipped) wrapper built around fetch with an intuitive syntax.

Wretch does not mutate its internal state. Each function returns a copy of the original object.

Wretch's syntax is readable and concise. Includes TypeScript definition files for autocompletion.

All methods are 100% chainable. Because a.b().c() is prettier than var z = a; z.b(); z.c().

Wretch is compatible with browsers and Node.js. Use any polyfill you like!

Use Addons to add new methods and capabilities. Use Middlewares to intercept requests and fully customize Wretch behaviour.
