convex-functions

Convex queries fetch data, mutations modify database state, and actions handle external side effects or third-party API integrations. Actions can orchestrate multiple mutations and interact with services outside the Convex database.

Validate arguments in Convex functions using the `v` validator object to define expected schema types. This ensures type safety and automatically rejects invalid inputs before the function logic executes.

Handle errors in Convex functions by throwing a `ConvexError`. This allows you to gracefully manage exceptions, return custom error messages, and control how runtime failures are surfaced to the client application.

Yes, you can use scheduled functions in Convex to run backend logic at a future time. This is useful for delayed tasks, timed notifications, or automating recurring backend operations.

HTTP actions in Convex allow you to expose backend functions as HTTP endpoints. They process incoming web requests, integrate with external services, and return HTTP responses to external callers.

Yes, this resource covers internal functions, which are used to structure and modularize your backend code. They allow you to share logic securely between queries, mutations, and actions without exposing them publicly.
