   ts

   import express from 'express';
   import { buildSchema } from 'graphql';
   import { graphqlHTTP } from 'express-graphql';
   import { remultGraphql } from 'remult/graphql';
   import { remultExpress } from 'remult/remult-express';
   
   const app = express();
   let api = remultExpress();
   app.use(api);
   const { schema, rootValue } = remultGraphql(api);
   app.use('/api/graphql', graphqlHTTP({
       schema: buildSchema(schema),
       rootValue,
       graphiql: true,
   }));
   app.listen(3002, () => console.log("Server started"));
