Function Creator

This generates Convex queries, mutations, and actions with all the boilerplate you need: argument validation with the v validators, return type definitions, authentication checks, and authorization logic. It knows when to use "use node" for actions that need Node.js APIs versus plain fetch, and pushes you toward the right patterns like calling mutations from actions instead of touching the database directly. The examples cover the full flow from checking auth to verifying ownership, which is honestly the part most tutorials skip. If you're building a Convex backend and tired of copying authentication boilerplate between functions, this gets you to working code faster.
