GraphQL Codegen Plugin Schema To Operations

Easily generate GraphQL operations for provided schema. Our motivation was to create the plugin to create operations for further processing by GraphQL Codegen (in our case to generate SWR and graphql-request SDK out of the box for basic CRUD operations).

Installation

Install the module:

$ yarn add @mvr-studio/graphql-codegen-plugin-schema-to-operations

Add it to your codegen.yaml:

generates:
  operations.graphql:
    schema: ./schema.graphql # or external address pointing to schema
    plugins:
      - '@mvr-studio/graphql-codegen-plugin-schema-to-operations'

That's it. Now you can run the codegen.

Usage

The plugin will likely transform given schema:

scalar Date

type AuthResponse {
  jwt: String!
}

type Mutation {
  logInUser(email: String!, password: String!): AuthResponse
}

type Query {
  me: User
}

enum Role {
  ADMIN
  USER
}

type User {
  id: String!
  email: String!
  name: String
  role: Role
  createdAt: Date!
  updatedAt: Date!
}

Into following operations:

query me_query {
  me {
    createdAt
    email
    id
    name
    role
    updatedAt
  }
}

mutation logInUser_mutation($email: String!, $password: String!) {
  logInUser(email: $email, password: $password) {
    jwt
  }
}

Additional Config

depthLimit

By default the plugin fetches fields for depthLimit=1 depth. But the property is adjustable like:

generates:
  operations.graphql:
    schema: ./schema.graphql # or external address pointing to schema
    config:
      depthLimit: 3
    plugins:
      - '@mvr-studio/graphql-codegen-plugin-schema-to-operations'
