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
}
}
