Backend Integration

Core queries map directly to backend query endpoints and generated query proxies.

Backend Query Styles

Arc supports both backend styles:

• Controller-based Queries
• Model-bound Queries

Both styles generate equivalent frontend proxy ergonomics.

Proxy Generation Benefits

• Compile-time contract safety
• IntelliSense for query parameters and results
• Automatic sync with backend contract changes
• Consistent wrapper/result handling

For setup details, see Backend Proxy Generation.

React Layer

For React hook-level patterns (use, Suspense, observable, paging), see React Queries.
