Rehive JavaScript SDK v4.0.0

A ground-up rewrite with a modular, tree-shakeable architecture and full TypeScript type safety.

What's new

• Modular imports -- import only the APIs you need; unused code is eliminated at build time
• Full TypeScript autocomplete on every method, parameter, and response
• 1,449 typed API methods across platform and 15 extensions
• 4 new extensions -- Billing, Builder, Rain, Alchemy
• Multi-session support -- switch between companies without re-authenticating
• Cross-tab session sync -- auth state syncs across browser tabs automatically
• Authenticated fetch -- createAuthenticatedFetch() for custom endpoints not in the SDK
• React integration -- AuthProvider + useAuth hook
• Zero runtime dependencies

Breaking changes

This is a major rewrite. All imports and usage patterns have changed.

• Monolithic Rehive client removed -- replaced by standalone factory functions (createAuth,
  createUserApi, createAdminApi, create*Api)
• Structured parameters -- all methods now use { query, body, path } instead of flat argument lists
• Extension namespaces flattened -- no more nested .user / .admin on extensions; all methods at top
  level
• Auth is standalone -- createAuth() is a separate module that API factories reference via { auth }
• Code generation engine changed -- migrated from swagger-typescript-api to @hey-api/openapi-ts
