The GraphQL Query to TypeScript Type Generator converts GraphQL queries, mutations, and field selections into strongly-typed TypeScript interfaces for variables and response payloads.

### Type Generation Mechanics The generator parses GraphQL operation syntax into clean TypeScript type definitions: - **Variable Interface Generation**: Extracts operation variable declarations (such as "$userId: ID!") and formats strongly-typed variable parameters ("userId: string"). - **Response Entity Modeling**: Generates interface definitions for selected fields and nested selection sets, mapping scalar types to TypeScript primitives (String/ID to string, Int/Float to number, Boolean to boolean). - **Nullable Field Protection**: Automatically types nested entity properties as nullable ("User | null") matching GraphQL schema specifications.

### Worked Conversion Example Converting a user profile query: - **GraphQL Operation**: "query GetUserProfile($userId: ID!) { user(id: $userId) { id name email followersCount isVerified } }" - **Generated TypeScript Variables**: "export interface GetUserProfileVariables { userId: string; }" - **Generated TypeScript Response**: "export interface User { id: string; name: string; email: string; followersCount: number; isVerified: boolean; }" "export interface GetUserProfileResponse { user: User | null; }"

### In-Browser Processing & Privacy Note All schema parsing and TypeScript interface generation execute entirely in local browser memory. No GraphQL queries, schemas, or API credentials are sent across external networks.
