Integrate with an existing GraphQL schema

Contents

You may have an existing GraphQL schema in your Enonic application, and wish to serve Guillotine from the same schema.

Example

/services/graphql/graphql.js 
var guillotineLib = require('/lib/guillotine');
var graphQlLib = require('/lib/graphql');

var schema = createSchema();

exports.post = function (req) {
    var body = JSON.parse(req.body);
    var result = graphQlLib.execute(schema, body.query, body.variables);
    return {
        contentType: 'application/json',
        body: JSON.stringify(result)
    };
};

function createSchema() {
    var context = guillotineLib.createContext(); (1)
    return context.schemaGenerator.createSchema({
        query: createRootQueryType(context),
        dictionary: context.dictionary (2)
    });
}

function createRootQueryType(context) {
    return context.schemaGenerator.createObjectType({
        name: 'Query',
        fields: {
            guillotine: {
                type: guillotineLib.createHeadlessCmsType(context), (3)
                resolve: function () {
                    return {};
                }
            }
        }
    });
}
1 Creates the context necessary to create Guillotine types.
2 Passes the dictionary to the schema creation. The use of a dictionary is necessary to define interface implementations.
3 Creates the Guillotine Headless CMS type
