SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill empowers developers to build robust backend logic using Convex, ensuring data integrity and efficient operations through well-defined queries, mutations, actions, and HTTP endpoints.

Core Features & Use Cases

  • Function Types: Understand and implement Queries (read-only, cached), Mutations (data modification), Actions (external API calls), and HTTP Actions (webhooks/APIs).
  • Validation & Error Handling: Implement argument validation using convex/values and handle errors gracefully with ConvexError.
  • Use Case: Securely process an incoming webhook from a payment gateway, validate the event, update the order status in the database via a mutation, and send a confirmation email using an action.

Quick Start

Use the convex-functions skill to create a mutation that inserts a new task into the database.

Frequently Asked Questions about convex-functions

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I handle external API calls in Convex backend functions?▼

Use Convex actions to handle external API calls in backend functions. Actions execute external API integrations and third-party service requests asynchronously, ensuring non-blocking database operations and robust external data processing.

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

In Convex, queries are read-only and cached for efficient data retrieval, while mutations handle data modification operations. Using the correct function type ensures optimal performance and secure database interactions within your application.

How to validate arguments and handle errors in Convex functions?▼

Validate arguments in Convex functions using the convex/values module. Handle errors gracefully by throwing ConvexError, ensuring data integrity and providing clear error messaging for invalid inputs during backend operations.

Can I process incoming webhooks using HTTP actions in Convex?▼

Yes, you can process incoming webhooks using HTTP actions in Convex. HTTP actions expose endpoints to receive external API events, allowing you to securely validate the event and trigger internal function calls like mutations.

How do I schedule tasks and call internal functions in a Convex backend?▼

Schedule tasks and call internal functions in a Convex backend by utilizing actions. This approach allows you to orchestrate complex workflows, chaining queries and mutations for real-time application requirements and robust data operations.
