Convert GraphQL Schemas to TypeScript Definitions Instantly

If you've ever spent an afternoon manually translating a sprawling GraphQL schema into TypeScript interfaces, you already know the pain. Types get mismatched, nullable fields slip through the cracks, and before you know it, your frontend is riddled with runtime errors that TypeScript was supposed to prevent. The GraphQL to TypeScript Converter eliminates that entire category of headaches by automating the translation process right in your browser.

This tool takes your raw GraphQL type definitions - queries, mutations, input types, enums, unions, and fragments - and produces clean, idiomatic TypeScript code that mirrors your schema exactly. Every field, every argument, every nested object type gets its own properly typed interface. Optional fields become optional properties. Enums stay enums. Union types become discriminated unions. The output is code you'd actually want to commit, not some half-baked approximation that needs a dozen manual fixes.

Why Manual Conversion Is a Losing Battle

GraphQL schemas evolve constantly. New fields get added, types get renamed, deprecated fields linger for months before someone removes them. Every time your schema changes, the corresponding TypeScript types need to change too. Doing this by hand is not just tedious - it's genuinely error-prone. A single missed nullable field can cascade into bugs that are difficult to trace. The GraphQL to TypeScript Converter gives you a single source of truth: paste your updated schema, get updated types, and move on with your life.

Unlike server-side code generation tools that require complex build pipelines, this converter runs entirely in your browser. There's nothing to install, no CLI to configure, no build step to integrate. You paste your GraphQL schema on one side and get TypeScript on the other. It's the kind of workflow that makes you wonder why you ever did it differently.

Handling the Tricky Parts of GraphQL-to-TypeScript Mapping

Not all GraphQL constructs map to TypeScript in obvious ways. Scalar types need sensible defaults - String becomes string, Int and Float become number, Boolean becomes boolean, and ID becomes string. Custom scalars like DateTime or JSON get mapped thoughtfully rather than being silently dropped.

Then there are union types and interfaces. In GraphQL, a union like SearchResult = User | Post | Comment needs to become a TypeScript discriminated union with proper type guards. Input types need their own dedicated interfaces separate from output types, because the nullability rules are different. This converter handles all of those edge cases so you don't have to think about them.

Built for Real Development Workflows

Whether you're building a React app with Apollo Client, a Next.js project with urql, or a Vue application with Villus, having accurate TypeScript types for your GraphQL operations is non-negotiable for a good developer experience. The GraphQL to TypeScript Converter fits into any of those workflows. Generate your types, paste them into your project's type definition file, and enjoy full autocomplete and type checking across your entire data layer.

For teams that maintain large schemas with hundreds of types, this tool is especially valuable during code reviews. Instead of eyeballing whether the types in a pull request match the schema changes, you can regenerate the types in seconds and diff the output. It turns a subjective review into an objective verification.

Privacy and Performance You Can Count On

Because the GraphQL to TypeScript Converter processes everything client-side, your schema never leaves your machine. This matters if you're working on proprietary APIs where the schema itself is confidential. There's no server round-trip, no data stored anywhere, and no third-party service involved. Just your browser doing the work locally, as fast as your machine allows.

Stop wasting time on mechanical type translation. Let the converter handle the boring parts so you can focus on building features that actually matter to your users.
