SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires supabase, graphql, typescript, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps in maintaining consistency between the Supabase schema types, GraphQL response mapping, and TypeScript domain contracts to prevent runtime mismatches before merging.

Core Features & Use Cases

Schema Validation: Check the alignment between the latest database schema and the queries.
GraphQL Mapping Validation: Ensure the mapping of GraphQL responses to TypeScript types is correct.
Error Handling Validation: Verify that the error handling and caching strategies are properly implemented.

Quick Start

Run the validate-data-contracts skill to check the consistency of your data contracts.

FAQPage Schema

How do I validate data consistency between Supabase, GraphQL, and TypeScript?▼

To validate data consistency, you check the alignment between your Supabase schema types, GraphQL response mapping, and TypeScript domain contracts to prevent runtime mismatches before merging.

What is TypeScript and GraphQL response mapping validation?▼

GraphQL response mapping validation ensures that the mapping of GraphQL responses to TypeScript types is correct, verifying that your data-driven application handles data types accurately.

How do I check if my GraphQL queries match my Supabase schema?▼

You can check schema alignment by validating the consistency between the latest Supabase database schema and your GraphQL queries, ensuring correct data handling and error management.

Does this data validation approach work with Supabase and TypeScript?▼

Yes, validating data contracts works directly with Supabase, GraphQL, and TypeScript integration to ensure correct data handling and verify error management strategies are properly implemented.

How do I verify error handling and caching strategies in a data-driven application?▼

You verify error handling and caching strategies by running a data contract validation process that checks if these strategies are properly implemented across your Supabase and GraphQL integration.

Why do I get runtime type mismatches between my database schema and TypeScript contracts?▼

Runtime type mismatches occur when there is a lack of consistency between your Supabase schema types, GraphQL response mapping, and TypeScript domain contracts, which needs validation before merging.
