Features

FastSprout is organized in layers so an application can use the pieces it needs.

Core

BaseSchema and typed fields describe input and output data. BaseAction gives class and function actions the same typed call shape. DTO visibility controls which fields are readable or writable. Start with the typed action guide or the core examples.

Data

DataR routes entities to their persistence implementations. Streams and joins allow typed data processing, including an in-memory joined stream. Install the data-sql extra for SQL-backed examples. See the data API and SQL API.

Events

EventBus publishes events in memory and delivers them to subscribers. The pub and sub decorators connect actions and handlers to a bus. Install the events extra and see the events guide, events examples, and events API.
