Validation And Behavior

Core queries validate input and provide predictable execution behavior.

Client-Side Validation

Validation metadata is generated from backend FluentValidation rules through the proxy generator.

const query = new SearchUsersQuery();
query.parameters = { searchTerm: 'ab', minAge: -5 };

const result = await query.perform();
// result.isValid === false
// result.validationResults contains validation errors

For general validation docs, see Validation.

Sorting And Paging

Queries include native sorting and paging primitives via Sorting and Paging.

For React usage patterns and generated hooks, see Paging.

Request Cancellation

When a newer request supersedes an active one, Arc cancels stale work to reduce race conditions and unnecessary processing.

Error Categories

Typical query failure categories include:

• Parameter validation errors
• Network failures
• Timeouts and cancellations
• Server exceptions
