Getting Started

Installation

graphile-build uses your local version of graphql to avoid conflicts, so you need to install both:

npm install --save graphile-build graphql

Building your Schema

The buildSchema method will (asynchronously) build a GraphQL schema from a list of plugins. We ship a number of default plugins that are sufficient to create a simple schema, like so:

const { buildSchema, defaultPlugins } = require("graphile-build");
const { printSchema } = require("graphql/utilities");

buildSchema(defaultPlugins).then(schema => {
  console.log(printSchema(schema));
});
// ES2017: const schema = await buildSchema(defaultPlugins);

This will generate a basic schema which supports the Relay Node interface.

# An object with a globally unique `ID`.
interface Node {
  # A globally unique identifier. Can be used in various places throughout the system to identify this single value.
  id: ID!
}

# The root query type which gives access points into the data universe.
type Query implements Node {
  # Exposes the root query type nested one level down. This is helpful for Relay 1
  # which can only query top level fields if they are in a particular form.
  query: Query!

  # The root query type must be a `Node` to work well with Relay 1 mutations. This just resolves to `query`.
  id: ID!

  # Fetches an object given its globally unique `ID`.
  node(
    # The globally unique `ID`.
    id: ID!
  ): Node
}

(See Omitting Plugins for how to make this schema even simpler by omitting the Node interface, and Options for how to pass options to plugins.)
