Custom GraphQL endpoint

If your graphql endpoint is not the default one coming with the overblog/graphql-bundle, then you might want to tell graphiql how to resolve the route depending on a schema name.

By default it uses Overblog\GraphiQLBundle\Config\GraphQLEndpoint\Helpers\OverblogGraphQLBundleEndpointResolver.

Configuration

Just set the overblog_graphiql.endpoint_resolver parameter like this:

# in app/config/config.yml
overblog_graphiql:
    # ...
    endpoint_resolver: \App\GraphiQL\EndpointResolver

The Resolver

The resolver must be something like this:

<?php

namespace App\GraphiQL;

class EndpointResolver
{
    public static function getByName($name)
    {
        if ('default' === $name) {
            return [
                'overblog_graphql_endpoint',
            ];
        }

        return [
            'graphql_default',
            ['schemaName' => $name],
        ];
    }
}

It must return an array of packed params which will be passed to RouterInterface::generate like this $router->generate(...$returnedValueOfTheGetByNameMethod).
