TypeScript GraphQL Files Modules

Webpack Integration

If you wish to have a simpler integration in a Webpack project, use graphql-let, it uses this plugin behind the scenes, and provides simpler developer experience.

Pre-Requirements#

To use this template, make sure you are using graphql-tag/loader with Webpack.

This plugin generates TypeScript typings for .graphql files containing GraphQL documents, which later on can be consumed using graphql-tag/loader or use string types if you will use the operations as raw strings, and get type-check and type-safety for your imports. This means that any time you import objects from .graphql files, your IDE will provide auto-complete.

This plugin also handles .graphql files containing multiple GraphQL documents, and name the imports according to the operation name.

⚠ Fragments are not generated with named imports, only as default imports, due to graphql-tag/loader behavior.

Installation

typescript-graphql-files-modules plugin version
Using yarn
yarn add -D @graphql-codegen/typescript-graphql-files-modules

API Reference

modulePathPrefix

type: string default: ``

Allows specifying a module definition path prefix to provide distinction between generated types.

Usage Examples

generates: src/api/user-service/queries.d.ts
documents: src/api/user-service/queries.graphql
plugins:
- typescript-graphql-files-modules
config:
# resulting module definition path glob: "*\/api/user-service/queries.graphql"
modulePathPrefix: "/api/user-service/"

relativeToCwd

type: boolean default: false

By default, only the filename is being used to generate TS module declarations. Setting this to true will generate it with a full path based on the CWD.

prefix

type: string default: *\/

By default, a wildcard is being added as prefix, you can change that to a custom prefix

type

type: string (values: DocumentNode, string) default: DocumentNode

By default, the named exports will have a type DocumentNode. Change this to "string" if you only use raw strings.

Example#

Given that you have a query named MyQuery in my-query.graphql file, this template will generate the following code:

declare module '*/my-query.graphql' {
import { DocumentNode } from 'graphql';
const MyQuery: DocumentNode;
export { MyQuery };
export default defaultDocument;
}

Accordingly, you can import the generated types and use it in your code:

import myQuery from './my-query.graphql';
// OR
import { myQuery } from './my-query.graphql';
