@graphql-codegen/typescript-operations

What is @graphql-codegen/typescript-operations?

The @graphql-codegen/typescript-operations package is a plugin for GraphQL Code Generator that generates TypeScript typings for GraphQL operations (queries, mutations, and subscriptions). It helps in creating type-safe and easy-to-use TypeScript types based on your GraphQL schema and operations, enhancing development efficiency and reducing runtime errors.

What are @graphql-codegen/typescript-operations's main functionalities?

Type generation for queries

Generates TypeScript interfaces for the 'GetUsers' query, allowing for type-safe usage of query results.

query GetUsers {
  users {
    id
    name
  }
}

Type generation for mutations

Generates TypeScript types for the 'CreateUser' mutation, including the mutation function and its parameters, facilitating type-safe API interactions.

mutation CreateUser($input: CreateUserInput!) {
  createUser(input: $input) {
    id
    name
  }
}

Type generation for subscriptions

Generates TypeScript types for the 'OnUserCreated' subscription, enabling type-safe real-time data handling.

subscription OnUserCreated {
  userCreated {
    id
    name
  }
}
