Gurkle

GraphQL client for Rust, with typed requests and responses, and subscriptions!

A fork of graphql_client and consumer of graphql-ws-rs.

Features

• Precise types for query variables and responses.
• Supports GraphQL fragments, objects, unions, inputs, enums, custom scalars and input objects.
• Works in the browser (WebAssembly).
• Subscriptions support (serialization-deserialization only at the moment).
• Copies documentation from the GraphQL schema to the generated Rust code.
• Arbitrary derives on the generated responses.
• Arbitrary custom scalars.
• Supports multiple operations per query document.
• Supports setting GraphQL fields as deprecated and having the Rust compiler check their use.

Usage

• Install the CLI tool.
• Run gurkle generate --schema-path <your schema> path/to/operations/*.graphql
• This will generate a mod.rs in your current directory.

Custom scalars

The generated code will reference the scalar types as defined in the server schema. This means you have to provide matching rust types in the scope of the struct under derive. It can be as simple as declarations like type Email = String;. This gives you complete freedom on how to treat custom scalars, as long as they can be deserialized.

Deprecations

The generated code has support for @deprecated field annotations.

Documentation for the generated modules

You can use cargo doc --document-private-items to generate rustdoc documentation on the generated code.
