Orbit is a composable data framework for managing the complex needs of today's web applications.

Although Orbit is primarily used as a flexible client-side ORM, it can also be used server-side in Node.js.

Orbit is designed for applications that need to:

  • Interact with data from a variety of sources: a REST server, a WebSocket stream, an IndexedDB backup, an in-memory store, etc.

  • Work offline, work online, and seamlessly transition between both modes.

  • Create optimistic and pessimistic user experiences (and even both in the same app).

  • Use a common schema to model data, regardless of its source.

  • Query and update data with a common set of expressions, understood across sources.

  • Track changes deterministically.

  • Fork immutable stores and then merge changes back if and when ready.

  • Support undo / redo.

Orbit is written in Typescript and distributed on npm through the @orbit organization. Pre-built distributions are provided in several module formats and ES language levels.
