Data

Data source abstractions and implementations.

This section documents the data-source API used by data-driven widgets and utilities. If you're building a custom data source, start with the protocol/base types.

See the DataSource Guide for usage examples and patterns.

Core types

• DataSourceProtocol: expected interface
• BaseDataSource: base implementation with hooks

Implementations

• MemoryDataSource: in-memory storage
• SqliteDataSource: SQLite-backed persistence
• FileDataSource: CSV, JSON, JSONL file loading
• FileSourceConfig: configuration for file-backed sources
