GraphQL to ReasonML

The purpose of this project is to transform a graphql schema into a reason file with type interfaces that when implemented constitute a graphql server.

Returning non primitive types

Built in types are automatically converted into reason types for example Float becomes float.

More complex types can be returned and enforced but some additional details need to be annotated via a special decorator.

type Cake @bsType(type: "CakeModule.t") {
  name: String!
}

type Query {
  cake: Cake!
}

Compiling the above will result in something like the following.

type cake('ctx) = {. "name": (CakeModule.t, __nameArgs, 'ctx) => string}
/* Arguments for name */
and __nameArgs = {.}
and query('root, 'ctx) = {
  .
  "cake": ('root, __cakeArgs, 'ctx) => CakeModule.t,
}
/* Arguments for cake */
and __cakeArgs = {.};

Usage

As the repository handles more and more usecases additional documentation will be added. For now take a look at the tests

Limitations

• GraphQL types must start with uppercase letter.
