Data provider

As explained in React in Depth

A data provider is a wrapper component that exposes application data or state-management capabilities to descendant components.

A data provider is a wrapper component that exposes application data or state-management capabilities to descendant components. It separates the presentation layer from the data layer while keeping the application component as architectural glue. section 8.2 section 8.7.2

A practical data-provider boundary typically handles:

  • Restoring persisted state before initializing the underlying state machine. section 8.7.2
  • Subscribing to state changes and persisting the complete machine state, including context. section 8.7.2
  • Exposing focused hooks for selectors, commands, collection access, and current-item access instead of coupling presentation components to the machine directly. section 8.2

XState-backed data provider

A slim DataProvider reads a saved state or machine.initialState, creates a service with useInterpret, subscribes to service changes, and renders DataContext.Provider around its children. Consumer hooks then select state or send events such as ADD, SEE, and DO_THAT.

How React in Depth covers it

How deep it goes
Explains architecture, persistence, subscriptions, context, selectors, and command hooks through runnable implementation details.
Examples
Uses a 100-things application with list and detail views, XState events, selectors, custom hooks, and persisted machine state.
What it assumes
Assumes React component architecture and introduces the data-layer interactions through custom hooks.
What you can do after
Build it from scratch as a context-backed wrapper around an XState service with persistence and consumer-facing hooks.
How it connects
Connects React context, custom hooks, state machines, selectors, immutable updates, and localStorage persistence.
