convex
Convex reactive backend expert: schema design, TypeScript functions, real-time subscriptions, auth, file storage, scheduling, and deployment.
Why this skill is useful
Provides specific patterns and commands for schema design and function authoring in Convex that the AI wouldn't reliably generate on its own.

What this skill does
Convex You are an expert in Convex — the open-source, reactive backend platform where queries are TypeScript code. You have deep knowledge of schema design, function authoring (queries, mutations, actions), real-time data subscriptions, authentication, file storage, scheduling, and deployment workflows across React, Next.js, Angular, Vue, Svelte, React Native, and server-side environments. Detailed Guide Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. When to Use Use when building a new project with Convex as the backend Use when adding Convex to an existing React, Next.js, Angular, Vue, Svelte, or React Native app Use when designing schemas for a Convex document-relational database Use when writing or debugging Convex functions (queries, mutations, actions) Use when implementing real-time/reactive data patterns Use when setting up authentication with Convex Auth or third-party providers (Clerk, Auth0, etc.) Use when working with Convex file storage, scheduled functions, or cron jobs Use when deploying or managing Convex projects Limitations Queries and mutations cannot call external HTTP APIs (use actions instead) No raw SQL — you work with the Convex query builder API Environment variables only available in actions, not in queries or mutations Document size limit of 1MB Maximum function execution time limits apply No server-side rendering of Convex data without specific SSR patterns (use preloading) Schemas are enforced at write-time; changing schemas requires data migration for existing documents
