SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the complexity of managing reactive backend functions, ensuring that developers implement queries, mutations, and actions with correct validation, error handling, and architectural best practices.

Core Features & Use Cases

  • Function Lifecycle Management: Provides clear guidance on when to use queries for reactive data, mutations for transactional writes, and actions for external API integrations.
  • Validation & Security: Enforces the use of argument and return validators to maintain type safety and data integrity across the Convex platform.
  • Use Case: When building a real-time messaging app, use this Skill to structure your message-sending mutation, ensuring it validates content, inserts data, and schedules background notifications efficiently.

Quick Start

Use the convex-functions skill to generate a new mutation that validates user input and updates the database with proper error handling.

FAQPage Schema
How do I structure Convex backend functions for real-time messaging and external API calls?▼

Structure Convex backend functions by using queries for reactive data reads, mutations for transactional database writes, and actions for external API integrations. This separation ensures reactive, transactional, and external-facing server-side logic operates efficiently.

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

Convex queries handle reactive data fetching, mutations manage transactional database writes, and actions execute external API integrations. Understanding these distinctions is essential for implementing correct server-side logic within the Convex ecosystem.

How do I add argument validation and error handling to a Convex mutation?▼

Add argument validation to a Convex mutation by enforcing strict argument and return validators. This maintains type safety and data integrity, while proper error handling patterns ensure robust transactional writes and scheduled background notifications.

When should I use HTTP endpoints instead of internal functions in a Convex backend?▼

Use HTTP endpoints in a Convex backend when exposing external-facing server-side logic. Internal functions should enforce strict security and validation, while HTTP endpoints handle incoming external requests and integrate with outside services.

Does Convex support TypeScript for type-safe database queries and API endpoints?▼

Convex supports TypeScript to ensure type safety across database queries, mutations, actions, and HTTP endpoints. Strict argument and return validators maintain data integrity and enforce type safety throughout the serverless backend ecosystem.

What are common limitations when managing reactive backend functions in a serverless database?▼

Limitations in managing reactive backend functions include complexity in ensuring correct argument validation, error handling, and architectural best practices. Without strict validators, maintaining type safety and data integrity across transactional writes becomes difficult.
