elm-gql

elm-gql is a code generation tool that bridges GraphQL and Elm, leveraging their similar type systems to produce type-safe Elm client code directly from GraphQL queries and mutations. It ensures correctness by validating queries against the GraphQL schema, saving development time while maintaining Elm's strong typing guarantees.

Key Features

• Schema Validation — Automatically verifies GraphQL queries and mutations against the schema, providing clear error messages for incorrect queries.
• Type-Safe Code Generation — Generates Elm code that mirrors GraphQL types, ensuring compile-time safety and reducing runtime errors.
• Production-Ready — Used in production for over a year, supporting complex application features with reliability.
• Elm-Esque Error Messages — Delivers user-friendly, Elm-style error messages to simplify debugging.
• Helper Code Generation — Creates helper files for constructing query inputs and referencing GraphQL enums, streamlining API integration.

Philosophy

elm-gql emphasizes type safety and developer experience by automating the translation of GraphQL to Elm, allowing teams to focus on building features rather than manual client code maintenance.
