Data-source reference

Data-source types and factories are exported from @sapporta/grid. A grid source resolves one level source for every materialized path. The runtime then uses that source for display state, optional queries, and optional writes.

Choose the reference that matches the coding task:

• Data-source contracts and state for GridDataSource, LevelDataSource, snapshots, loading and error state, query capabilities, and source lifecycle.
• Runtime data access for GridLevelRuntime.data, query calls, subscriptions, and React observation.
• Data-source writes and reconciliation for writable sources, level mutation methods, and authoritative results.
• In-memory and REST data sources for the built-in local and remote source factories and query-state ownership.

Start with the Data sources guide when choosing between local, remote, and custom ownership.
