convex-functions

Convex functions enable real-time data synchronization by using queries for cached reads and mutations for transactional writes. You can build a real-time chat app by implementing mutations to send messages and queries to fetch message history.

Convex queries are read-only and cached, mutations are read/write and transactional, and actions handle external API integrations. HTTP actions specifically serve as webhooks or API endpoints for external service communication.

You validate arguments in Convex functions using convex/values for robust type checking. Handle errors by throwing ConvexError to provide user-friendly error messages for invalid inputs or failed operations.

Yes, Convex HTTP actions function as webhooks and API endpoints to integrate with external APIs. They allow your backend to receive incoming requests and communicate with external notification services.

To create a Convex mutation that inserts data, define a mutation function that takes arguments like name and email, validate them using convex/values, and insert the record into your target table such as users.

Yes, Convex supports scheduled execution for backend actions. This allows you to time-delay or automate specific actions, facilitating robust integration with external APIs and recurring data synchronization tasks.
