convex-functions

To return user-friendly error messages in Convex mutations, throw a `ConvexError` within your function logic. This allows you to handle validation failures and communicate specific issues clearly to the client application.

Convex mutations synchronously modify your database, while actions orchestrate asynchronous tasks and external API integrations. Actions can also wrap internal functions to securely execute sensitive operations within your backend logic.

Handle external API integration in Convex by using actions. Actions execute in a Node.js environment, allowing you to fetch external services and interact with third-party APIs without blocking your real-time database queries.

Yes, you can use scheduled functions in Convex to handle asynchronous tasks. This allows your backend to automatically trigger mutations or actions at specific times or intervals for recurring background processing.

Secure sensitive operations in a Convex backend by defining them as internal functions. These functions cannot be called directly from the client, ensuring they are only executed through safe server-side actions.
