Orbit is a composable TypeScript data framework for orchestrating access, transformation, and synchronization across multiple data sources such as REST servers, WebSockets, IndexedDB, and in-memory stores. It provides Git-like deterministic change tracking, offline support with queued sync, and optimistic/pessimistic request coordination for web applications.

Use cases

• sync data between a REST API and local IndexedDB cache
• build an offline-first web app that queues changes while offline
• implement undo/redo editing in a client-side app
• manage a client-side ORM with a shared schema across sources
• fork and merge immutable data stores for branching caches
• coordinate optimistic and pessimistic updates across data sources

When to choose

• your app needs offline support with automatic synchronization when back online
• you need to coordinate data across multiple sources like REST, WebSocket, and local storage
• you want deterministic change tracking with fork/merge semantics
• you need undo/redo or optimistic UI patterns in a data-heavy SPA

When to avoid

• you need a simple REST client with minimal data layer complexity
• your project requires a battle-tested 1.0 release rather than a 0.x version
• you want a full backend ORM for server-side relational databases
• your team cannot invest in learning a niche data framework with a small community
