Why Generate TypeScript from GraphQL?
Type-safe code reduces runtime errors and improves developer experience. Generating TypeScript types from your GraphQL schema ensures your frontend code stays in sync with your API contract.
FAQ
What GraphQL types are converted?
The converter handles type/interface definitions, input types, enums, and scalar types. It properly maps GraphQL scalars (String, Int, Float, Boolean, ID) to TypeScript equivalents.
How are nullable fields handled?
GraphQL fields without ! are treated as nullable and become 'type | null' in TypeScript. Optional markers (?) are added for nullable fields to match GraphQL semantics.
Should I use interfaces or type aliases?
Both work well. Interfaces are more common in OOP-style code and allow extension. Type aliases are more flexible for union types. Most teams prefer interfaces for GraphQL types.
