## What it is
Hyper Fetch is a type-safe TypeScript framework for fetching and real-time data exchange, unifying REST, GraphQL, Firebase, WebSockets, and SSE behind one client with built-in caching, retries, queues, and offline replay. It includes a CLI that generates fully typed SDKs from OpenAPI/Swagger schemas and React bindings with hooks.

## Use cases
- replace axios and react-query with one typed data layer
- generate a typescript sdk from an openapi spec
- fetch rest apis with full type safety
- handle websockets and rest with the same client
- cache responses and do optimistic updates with rollback
- support offline requests with queueing and replay
- connect to firebase realtime data in a typed way

## When to choose
- you want one consistent, fully typed client for REST, GraphQL, sockets, and SSE
- you need caching, retries, dedup, and offline support without gluing multiple libraries
- you want SDK code generation from OpenAPI/Swagger schemas
- you build React, Next.js, React Native, or Electron apps needing unified data flow

## When to avoid
- you need a minimal fetch wrapper and prefer tiny dependencies like axios or ky
- your team is already invested in React Query/SWR plus a separate socket library
- you work outside the TypeScript/JavaScript ecosystem
- you need server-side data fetching patterns beyond what its Next.js/SSR support covers
