SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide to writing and understanding Convex functions, ensuring robust data operations with proper validation, error handling, and efficient runtime considerations.

Core Features & Use Cases

  • Function Types: Learn to implement Queries, Mutations, Actions, and HTTP Actions.
  • Validation & Error Handling: Implement argument validators and handle errors gracefully using ConvexError.
  • Use Case: Develop a secure and efficient backend for your application by implementing user authentication mutations, data retrieval queries, and external API integrations via actions.

Quick Start

Use the convex-functions skill to implement a mutation that creates a new task in the database, ensuring the user exists before insertion.

FAQPage Schema
How do I implement Convex functions for backend database operations?▼

Convex functions enable robust backend logic by detailing the implementation of queries, mutations, and actions with integrated argument validation and error handling. You can develop secure data operations using Convex.js.

What is the difference between queries, mutations, and actions in Convex?▼

Queries retrieve data, mutations modify database records, and actions handle external API integrations or multi-step operations. Convex functions provide structured implementations for all three to ensure efficient application development.

How do I validate arguments and handle errors in Convex mutations?▼

You validate arguments and handle errors in Convex mutations using built-in argument validators and the ConvexError class. This ensures robust data operations by gracefully managing invalid inputs and runtime failures.

Can I use HTTP actions for external API integrations in Convex?▼

Yes, Convex supports HTTP actions specifically for external API integrations. You can implement these HTTP actions alongside standard functions to securely connect your backend with external services.

Does Convex support TypeScript for writing secure backend functions?▼

Yes, Convex functions fully support TypeScript to write secure and efficient backend logic. You can implement user authentication mutations and data retrieval queries with strict type validation.
