graphql-codegen-typescript-document-nodes

This is a plugin for GraphQL Code Generator that generates Typescript source file from GraphQL files.

Generated modules export GraphQL as an AST document nodes. Modules use graphql-tag module.

Requirements

This package requires ES6 with Node >= 8.

Usage

Configuration in codegen.yml file:

overwrite: true
schema: 'schema/index.json'
documents: 'operations/*.graphql'
generates:
  operations/index.ts:
    plugins:
      - graphql-codegen-typescript-document-nodes
    config:
      namingConvention: lowerCamelCase
      nameSuffix: Query

With GitHub GraphQL API v4 schema and following GraphQL operation:

query Viewer {
  viewer {
    login
    name
  }
}

It will generate following Typescript code:

import { DocumentNode } from 'graphql';
import gql from 'graphql-tag';
 
export const viewerQuery: DocumentNode = gql`
  query Viewer {
    viewer {
      login
      name
    }
  }
`;

Configuration

namingConvention

Allow you to override the naming convention of the output. You can either override all namings, or specify an object with specific custom naming convention per output. The format of the converter must be a valid module#method. You can also use "keep" to keep all GraphQL names as-is. Additionally you can set transformUnderscore to true if you want to override the default behaviour, which is to preserve underscores.

Override All Names:

config:
  namingConvention: change-case#lowerCase

Upper-case enum values:

config:
  namingConvention: change-case#pascalCase

Keep:

config:
  namingConvention: keep

Transform Underscores:

config:
  namingConvention: change-case#pascalCase
  transformUnderscore: true

namePrefix

Adds a prefix to GraphQL operation name

nameSuffix

Adds a suffix to GraphQL operation name
