Betterauth Tanstack Convex

The betterauth-tanstack-convex skill integrates authentication, state management, and backend logic into a unified stack. It leverages BetterAuth for secure user sessions, TanStack Query for efficient data fetching, and Convex for real-time, serverless database operations. This combination allows AI agents to build full-stack applications with synchronized data and seamless user experiences.

When to use it

• Building applications requiring real-time data synchronization across clients and servers.
• Implementing secure authentication flows that need to persist session states reliably.
• Developing projects where offline-first capabilities or optimistic UI updates are critical.
• Creating scalable backend solutions without managing traditional server infrastructure.

Key capabilities

• BetterAuth: Handles user registration, login, and session management securely.
• TanStack Query: Manages server state with automatic caching, deduplication, and background refetching.
• Convex: Provides a real-time backend with built-in schema validation, indexing, and live data subscriptions.
• Unified Stack: Combines these tools to reduce boilerplate code and streamline development workflows.

Example prompts

• "Generate a secure login page using BetterAuth that updates the UI immediately upon successful authentication."
• "Create a real-time chat feature where messages are stored in Convex and displayed instantly using TanStack Query."
• "Set up a user dashboard that fetches profile data from Convex and caches it efficiently with TanStack Query."

Tips & gotchas

Ensure you have a basic understanding of TypeScript, as this stack relies heavily on type safety across all components. When configuring Convex, be mindful of the real-time subscription costs if your application expects high-frequency updates from many users simultaneously.
