MS SQL doesn't return data in NodeJS

I created config file for database like below:

module.exports.connection = {
  sqlserver: {
    user: 'user_name',
    password: 'password',
    server: 'servername\\instancename',
    database: 'database_name',
    port: 1433,
  },
};

I have a simple table in database:

enter image description here

I'm trying get a data from table above like below:

const sql = require('mssql');
const config = require('../config/connection');

sql.connect(config.connection.sqlserver).then((pool) => pool.request().query('select type from dbo.category')).then((result) => {
  console.log(result);
}).catch((err) => {
  console.log(err);
});

sql.close();

Unfortunately I doesn't see anything in console and I don't have any error so I can't find what's wrong. I tried also:

sql.connect(config.connection.sqlserver).then((pool) => pool.request().query('select type from dbo.category')).catch((err) => {
    console.log(err);
  }).then((result) => {
    console.log(result);
  }).catch((err) => {
    console.log(err);
  });
  sql.close();

I used https://www.npmjs.com/package/mssql#promises. I'm trying to do it on my nodeJs server. Any ideas?

I resolved my problem. Thanks for Julia Shestakova suggestions. My query function looks like this:

const sql = require('mssql');
const config = require('./config/connection');
module.exports = {
  query(query) {
    return sql.connect(config.connection.sqlserver).then(() => sql.query(query)).then((result) => {
      sql.close();
      return result.recordset;
    }).catch((err) => console.log(err));
  },
};

I'm returning Promise so I can use then to presentation my data when I'm calling query function on a server.
