What is GraphQL to TypeScript Resolver Generator?
This tool converts GraphQL Schema Definition Language (SDL) into TypeScript resolver type definitions. It generates type-safe resolver interfaces for Query, Mutation, and Subscription operations, along with optional implementation stubs.
How to Use
- Paste your GraphQL schema SDL into the input area
- Toggle "Include resolver stubs" if you want boilerplate implementation code
- Click "Generate TypeScript" to create the type definitions
- Switch between Types and Resolvers tabs to view different outputs
- Copy the generated code and integrate it into your GraphQL server project
Why Use This Tool?
Tips & Best Practices
- Use the resolver stubs as a starting point and fill in your actual implementation
- The Context interface can be customized to include authentication, database connections, etc.
- Input types are converted to TypeScript interfaces for type-safe arguments
- Subscription resolvers use AsyncIterator type for real-time events
Frequently Asked Questions
What GraphQL features are supported?
This tool supports types, inputs, Query, Mutation, Subscription, field arguments, non-null (!), and list types ([]). Enums and interfaces are parsed but generate basic types.
How do I use the generated code?
Copy the types and resolvers into your project. Implement the resolver functions by replacing the stub code. Use with Apollo Server, GraphQL Yoga, or any TypeScript GraphQL server.
What is the Context interface?
Context is passed to every resolver and typically contains request-scoped data like the current user, database connections, or other services. Customize it based on your needs.
Is my schema sent to a server?
No, all processing happens entirely in your browser. Your GraphQL schema never leaves your device.
