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 are available in app queries, mutations and actions; components have distinct binding/isolation rules. Never return secrets to clients.
• 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

• The bundled examples mutate/deploy cloud data and are incomplete; apply only to confirmed deployments with least privilege, backups and staged checks. No runtime/cloud validation is included.
