convex-functions

You add input validation to Convex server functions by declaring explicit typed validators from convex/values for queries, mutations, actions, and HTTP actions. This provides structured data access and reliable execution.

Handle errors in Convex mutations and actions by applying safe error handling patterns and using internal functions for sensitive logic. This approach separates concerns and maintains reliability across backend operations.

Yes, Convex supports external API calls and scheduled tasks through its server-side action and HTTP action functions. Using typed validators and safe error handling ensures these external operations execute securely and predictably.

Yes, you need TypeScript definitions to write Convex queries and mutations effectively. Standard Convex tooling requires explicit TypeScript validators and typed returns for all function types to ensure safe server-side execution.

Use internal mutations in Convex when executing sensitive logic that should not be directly exposed to the client. This security pattern ensures reliable separation of concerns and protects structured backend data access.
