GraphQL

Generates GraphQL Schema Definition Language (SDL) types.

Type Mappings

Example

Rust:

#![allow(unused)]
fn main() {
#[derive(TypeWriter)]
#[sync_to(graphql)]
pub struct User {
    pub id: String,
    pub email: String,
    pub age: Option<u32>,
}
}

Generated:

scalar DateTime
scalar JSON

type User {
  id: ID!
  email: String!
  age: Int
}

Enums

Simple enums become GraphQL enums:

Rust:

#![allow(unused)]
fn main() {
#[derive(TypeWriter)]
#[sync_to(graphql)]
pub enum Role {
    Admin,
    User,
    Guest,
}
}

GraphQL:

enum Role {
  ADMIN
  USER
  GUEST
}

File Naming

Files use snake_case by default: UserProfile → user_profile.graphql

[graphql]
file_style = "kebab-case"  # user-profile.graphql
