GraphQL Modules is a toolset of libraries and guidelines dedicated to create reusable, maintainable, testable and extendable modules out of your GraphQL server.

• Website
• Introducing GraphQL Modules - Feature based GraphQL Modules at scale
• Why is True Modular Encapsulation So Important in Large-Scale GraphQL Projects?
• Why did we implement our own Dependency Injection library for GraphQL-Modules?
• Scoped Providers in GraphQL-Modules Dependency Injection
• Writing a GraphQL TypeScript project w/ GraphQL-Modules and GraphQL-Code-Generator
• Authentication and Authorization in GraphQL (and how GraphQL-Modules can help)
• Authentication with AccountsJS & GraphQL Modules
• Manage Circular Imports Hell in GraphQL-Modules

Highlights

• Reusable modules - Modules are defined by their GraphQL schema (Schema first design). They're completely independent and can be shared between apps.
• Scalable structure - Manage multiple teams and features, multiple micro-services and servers.
• Gradual growth - A clear, gradual path from a very simple and fast, single-file modules, to scalable multi-file, multi-teams, multi-repo, multi-server modules.
• Testable - A rich toolset around testing, mocking and separation.

Documentation

Documentation is available at graphql-modules.com or inside the docs directory.

Installation

To install graphql-modules, use the following:

$ npm install @graphql-modules/core

# Or, with Yarn

$ yarn add @graphql-modules/core

Or, in alternative, just use the graphql-modules-seed to get started:

$ git clone https://github.com/darkbasic/graphql-modules-seed.git

Pre-release

We are also publishing a pre-release version to NPM on each change.

Just take a look at the build status on CircleCI and find "Publish Canary" job to get the published version.

Usage

More advanced usage at graphql-modules.com

import { GraphQLModule } from '@graphql-modules/core';

const module = new GraphQLModule({
  typeDefs: gql`
    type Post {
      id: ID
      title: String
      author: User
    }

    type Query {
      posts: [Post]
    }
  `,
  resolvers: blogResolvers,
  imports: [UserModule]
});

Inside the examples directory you can find the following examples:

• Simple GraphQL-Modules example
• Using dependency injection in GraphQL Modules
• You can also take a look at the graphql-modules-seed repository.

GraphQL Code Generator integration

GraphQL Modules easily integrates with GraphQL Code Generator. To see how look at the graphql-modules-seed.

Troubleshoot

If you have issues with the generator, feel free open issues in this repository.

Contributing

Feel free to open issues (for bugs/questions) and create pull requests (add generators / fix bugs).
