graphql-serve

Fully functional GraphQL Server based on Graphback CRUD Specification

graphql-serve is a full-featured GraphQL server, based on Graphback and Apollo Server. With the minimum configuration required, you have a server ready for testing GraphQL client applications or libraries. Unlike mocking alternatives, graphql-serve offers persistent data between queries and mutation using in-memory SQLite database.

Getting Started

Installation

Using npm:

npm install -g graphql-serve

or yarn:

yarn global add graphql-serve

Usage

gqlserve

The gqlserve command only needs one or more *.graphql data model file(s) in order to setup a working GraphQL server. Here is an example model file:

""" @model """
type Note {
  id: ID!
  title: String!
  description: String
  likes: Int
}

Assuming you have created your various *.graphql data model files in the models directory, to automatically generate resolvers and start a GraphQL server listening on port 8080 do the following:

$ gqlserve serve models --port=8080

If you only need to see the generated GraphQL Schema, use the print-schema command:

$ gqlserve print-schema .

The above command prints schema generated from data model files in the current directory.

This information is also provided with the command itself:

$ gqlserve -h
gqlserve <command>

Commands:
  gqlserve print-schema [modelDir]     Generate and print GraphQL schema from data
                                   model files
  gqlserve serve [modelDir] [options]  Generate and start GraphQL server from data
                                   model files

Options:
  -h, --help     Show help                                             [boolean]
  -v, --version  Show version number                                   [boolean]

For the serve command:

$ gqlserve serve -h
gqlserve serve [modelDir] [options]

Generate and start GraphQL server from data model files

Positionals:
  modelDir, model  Directory to search for data models                  [string]

Options:
  --port, -p        Specify the port on which to listen on              [number]
  --datasync, --ds  Enable datasynchronization features                [boolean]
  -h, --help        Show help                                          [boolean]
  -v, --version     Show version number                                [boolean]

Examples:
  gqlserve serve . -p 8080  generate schema from data model files in current
                            directory and start GraphQL server on port 8080

Also for print-schema command:

$ gqlserve print-schema -h
gqlserve print-schema [modelDir]

Generate and print GraphQL schema from data model files

Positionals:
  modelDir, model  Directory to search for data models                  [string]

Options:
  -h, --help     Show help                                             [boolean]
  -v, --version  Show version number                                   [boolean]

Examples:
  gqlserve print-schema modelDir  only display generated schema from data model
                              files in modelDir directory and quit

Under to hood we use Graphback to parse the Type Definitions/Data Model and generate the GraphQL schema and resolvers. See the Graphback Docs on Data Model Definition and Data Synchronization for data synchronization features.
