convex-functions

To build backend logic in Convex, you implement queries to fetch data and mutations to modify database records. This approach uses integrated argument validation and error handling to ensure secure and efficient database operations.

Convex actions are used for internal function calls requiring external API integration, while HTTP actions expose endpoints for external web requests. Both handle runtime considerations and support argument validation for secure execution.

You validate arguments in Convex functions using the `v` validator and handle errors using `ConvexError`. This combination ensures robust error management and prevents invalid data from entering your database operations.

Yes, you can use internal functions within Convex actions to enforce modularity and security. This design separates external API calls from core database operations, addressing runtime considerations and maintaining a clean architecture.

The best way to integrate external API calls in a Convex backend is by using actions. Actions handle external requests and notifications securely, keeping external side effects separate from your synchronous database queries and mutations.

Convex functions enable real-time application development by combining mutations for data writes, queries for fetching live history, and actions for external notifications. This provides a secure, efficient framework with built-in validation.
