How to execute GraphQL query from server

Question

I use graphql-express to create an endpoint where I can execute graphql queries. Although I use Sequelize with an SQL database, it is embarrassing to use it directly from the server outside of my graphql functions resolve. How do I access my graphql API from the same server as in it?

This is how I set the graphql endpoint:

const express = require('express');
const router = express.Router();
const graphqlHTTP = require('express-graphql');
const gqlOptions = {
   schema: require('./schema')
};
router.use('/', graphqlHTTP(gqlOptions));

modules.exports = router;

Basically, I want to be able to do something like this:

query(`
  {
    user(id: ${id}) {
      name
    }
  }
`)

How do I create this function query?

graphql(schema, query).then(result => {

const {graphql} = require('graphql');
const schema = require('./schema');
function query (str) {
  return graphql(schema, str);
}

query(`
  {
    user(id: ${id}) {
      name
    }
  }
`).then(data => {
  console.log(data);
})
