Usage

You can start a GraphQL server using bs-graphql, bs-express and this binding:

let app = Express.App.make ();
let schema = GraphQL.Utilities.buildSchema "type Query { hello: String }";
let rootValue = {"hello": fun () => "world"};
external bodyParserJson : unit => Express.Middleware.t = "json" [@@bs.module "body-parser"];
Express.App.use app (bodyParserJson ());
let graphqlMiddleware = ApolloServerExpress.createGraphQLExpressMiddleware schema ::rootValue;
let graphiqlMiddleware = ApolloServerExpress.createGraphiQLExpressMiddleware "/graphql";
Express.App.useOnPath app graphqlMiddleware path::"/graphql";
Express.App.useOnPath app graphiqlMiddleware path::"/graphiql";
Express.App.listen app port::8080;

Now you can make GraphQL queries to http://localhost:8080.
