The second argument to buildSchema and getBuilder is an options object with arbitrary properties which is made available to every plugin as its second argument.

Supported Options

The following options apply to the default plugins:

• nodeIdFieldName - defaults to id which might clash with your other fields. It is not recommended to change it, but you might consider nodeId instead. (Use of __id is discouraged because GraphQL wants to deprecate non-introspection fields that begin with __)

Plugins may expect further options if they wish, for example see those of graphile-build-pg. To prevent collisions between the property names, the plugins should follow some namespacing conventions.

Example

The following example passes the nodeIdFieldName setting through, changing from the default id to flibble:

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

buildSchema(defaultPlugins, { nodeIdFieldName: "flibble" }).then(schema => {
  console.log(printSchema(schema));
});

which modifies the Node interface thusly:

interface Node {
  # A globally unique identifier. Can be used in various places throughout the system to identify this single value.
  flibble: ID!
}
