FAQPage Schema

How do I generate typed Convex API endpoints with authentication and validation?▼

You generate typed Convex API endpoints by describing the endpoint name, arguments, and returns, which produces code with argument validation, return type validation, and authentication guards for queries, mutations, and actions.

What is the best way to add authorization checks to Convex mutations and queries?▼

The best way to add authorization checks is to scaffold endpoints using structured patterns that enforce access control and consistent error handling across read, write, and external actions within your backend workflow.

Does this approach support generating Convex actions with Node.js for external API calls?▼

Yes, this approach supports generating Convex actions with Node.js usage, ensuring proper separation of concerns when executing external actions alongside standard validated queries and mutations.

Can I enforce return type validation on Convex backend functions?▼

Yes, you can enforce return type validation on Convex backend functions. The generation process applies type safety to both incoming arguments and outgoing return values for robust API consistency.

How do I structure Convex endpoints to separate read, write, and external actions?▼

You structure Convex endpoints by generating distinct queries, mutations, and actions. This enforces a clear separation of concerns, applying Node.js usage for external actions and validation for read/write operations.

Why do my Convex API endpoints lack consistent error handling and access control?▼

Convex API endpoints often lack consistent error handling and access control due to repetitive manual setup. Generating functions with established best practices ensures uniform authorization and validation patterns across endpoints.
