graphql-rest-mocks

Getting Started

Run npm i graphql-rest-mocks

Create a folder called ./contracts in your repository

Add a file called HelloWorld.graphql, with these contents:

type Request {
  id: ID!
}

type Response {
  string: String!
}

Add this script to your package.json:

{
  "scripts": {
    "start": "graphql-rest-mocks start ./contracts"
  }
}

Run npm run start

Visit localhost:4000/HelloWorld?id=200

You'll see a mock server producing data.

Add global types

Create a folder called ./types

Add a file called GlobalType.graphql, with these contents:

type GlobalType {
  someGlobalId: ID!
}

Change HelloWorld.graphql to use that global type, as below:

type Request {
  id: ID!
}

type Response {
  string: String!
  globalType: GlobalType!
}

No need to import it, or do anything fancy. Any type, scalar or enum declared in the global types folder is available to all contracts.

Change the script to use the types folder:

{
  "scripts": {
    "start": "graphql-rest-mocks start ./contracts --types ./types"
  }
}
