convex-functions

To build reliable Convex backend functions, you implement queries, mutations, and actions with enforced argument and return validators, transactional writes, and safe error handling for production data access.

The best way to handle external API calls and webhooks in Convex is by using HTTP actions, which bridge Convex with outside services and isolate external network calls from database operations.

You validate arguments and returns in Convex queries and mutations by enforcing built-in validators on function inputs and outputs, ensuring reliable data access and preventing invalid server-side workflows.

Use Convex internal functions and scheduled jobs when you need to execute sensitive operations or run delayed and recurring server-side tasks without exposing them directly to client-side calls.

Yes, you can use Convex functions with Next.js to build production server-side workflows, applying runtime selection and safe error handling to manage data access and external integrations reliably.
