convex-functions

To add argument validation to Convex mutations and queries, define explicit input validators and type-safe schemas directly within your function definitions. This enforces strict runtime checks and prevents invalid data from entering your backend.

Convex actions are server-side functions used for external integrations and multi-step logic, while HTTP actions specifically handle external HTTP requests. Both can isolate sensitive logic by calling internal functions to maintain security boundaries.

Use internal functions in your Convex backend when you need to isolate sensitive logic from public access. They ensure that critical data access patterns and internal request flows cannot be triggered directly by external clients.

Yes, Convex supports scheduling and error handling for backend functions. You can implement resilient data access patterns and external integrations using best-practice guidance for runtime-aware execution across web and native apps.

The best way to structure scalable Convex functions is to apply explicit validators for arguments and returns, isolate sensitive operations in internal functions, and follow runtime-aware patterns for queries, mutations, and actions.
