What is GraphQL to Apollo React Hooks Generator?
This tool converts GraphQL Schema Definition Language (SDL) into React Apollo hooks. It generates TypeScript hooks using useQuery for Query operations, useMutation for Mutation operations, and useLazyQuery for lazy query execution. Each hook includes proper TypeScript typing, variable interfaces, and gql template literals.
How to Use
- Paste your GraphQL schema SDL (including Query and Mutation types) into the input area
- Click "Generate" to create the Apollo React hooks
- Review the generated TypeScript code with typed hooks and gql documents
- Copy the output and add it to your React project
Why Use This Tool?
Tips & Best Practices
- Make sure your schema includes both Query and Mutation types for full hook generation
- Input types are automatically converted to TypeScript interfaces with the "Input" suffix
- Required fields (!) are mapped to required TypeScript properties, optional fields to optional (?)
- Customize the generated selection sets to include the fields your components need
Frequently Asked Questions
What is Apollo Client?
Apollo Client is a comprehensive state management library for JavaScript that enables you to manage both local and remote data with GraphQL. It provides React hooks like useQuery, useMutation, and useLazyQuery for declarative data fetching.
How are Query operations converted?
Each field in the Query type generates a useQuery hook and a useLazyQuery hook. The hook name follows the pattern use + PascalCase(fieldName). Variable types are generated from the field arguments.
How are Mutation operations converted?
Each field in the Mutation type generates a useMutation hook. The hook name follows the pattern use + PascalCase(fieldName). Variable types are generated from the mutation arguments.
What about subscriptions?
The current version focuses on queries and mutations. For subscriptions, you can use the useSubscription hook from @apollo/client with a manually written subscription document.
Is my schema sent to a server?
No, all processing happens entirely in your browser. Your GraphQL schema never leaves your device.
