Mock your future API or extend the existing API with realistic data from faker.js. No coding required. All you need is to write GraphQL IDL. Don't worry, we will provide you with examples in our IDL editor.

We use @fake directive to let you specify how to fake data. And if 60+ fakers is not enough for you, just use @examples directive to provide examples. Just add a directive to any field or custom scalar definition:

type Person {
  name: String @fake(type: firstName)
  gender: String @examples(values: ["male", "female"])
}

No need to remember or read any docs. Autocompletion is included!

• 60+ different types of faked data e.g. streetAddress, firstName, lastName, imageUrl, lorem, semver
• Comes with multiple locales supported
• Runs as a local server (can be called from browser, cURL, your app, etc.)
• Interactive editor with autocompletion for directives with GraphiQL embeded
• ✨ Support for proxying existing GraphQL API and extending it with faked data

npm install -g graphql-faker

or

yarn global add graphql-faker

Mock GraphQL API based on IDL and open interactive editor:

graphql-faker ./my-idl.grqphql --open

Extend real data from SWAPI with faked based on extension IDL:

graphql-faker ./ext-swapi.grqphql --extend http://swapi.apis.guru

Extend real data from GitHub API with faked based on extension IDL (you can get token here):

graphql-faker ./ext-gh.graphql --extend https://api.github.com/graphql \
--header "Authorization: bearer <TOKEN>"
