SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide to building secure, efficient, and well-validated backend functions using Convex, covering queries, mutations, actions, and HTTP endpoints.

Core Features & Use Cases

Function Types: Understand and implement Queries (read-only, cached), Mutations (read/write, transactional), Actions (external APIs), and HTTP Actions (webhooks/APIs).
Validation & Error Handling: Learn to use convex/values for robust argument validation and ConvexError for user-friendly error messages.
Use Case: Develop a real-time chat application by implementing mutations to send messages, queries to fetch message history, and actions to integrate with a notification service.

Quick Start

Use the convex-functions skill to create a mutation that inserts a new user into the 'users' table with provided name and email arguments.

FAQPage Schema

How do I build backend logic with Convex functions for real-time data synchronization?▼

Convex functions enable real-time data synchronization by using queries for cached reads and mutations for transactional writes. You can build a real-time chat app by implementing mutations to send messages and queries to fetch message history.

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

Convex queries are read-only and cached, mutations are read/write and transactional, and actions handle external API integrations. HTTP actions specifically serve as webhooks or API endpoints for external service communication.

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

You validate arguments in Convex functions using convex/values for robust type checking. Handle errors by throwing ConvexError to provide user-friendly error messages for invalid inputs or failed operations.

Can I use Convex HTTP actions to integrate external APIs and webhooks?▼

Yes, Convex HTTP actions function as webhooks and API endpoints to integrate with external APIs. They allow your backend to receive incoming requests and communicate with external notification services.

How do I create a Convex mutation to insert data into a database table?▼

To create a Convex mutation that inserts data, define a mutation function that takes arguments like name and email, validate them using convex/values, and insert the record into your target table such as users.

Does Convex support scheduled execution for backend actions?▼

Yes, Convex supports scheduled execution for backend actions. This allows you to time-delay or automate specific actions, facilitating robust integration with external APIs and recurring data synchronization tasks.
