我如何将mysql-promise导出为节点Js中的模块？

Question

Here I have a simple config file for a postgres db:

const pg = require('pg-promise')()

const connectionString = {
    host: 'localhost',
    port: 8080,
    database: 'test',
    user: 'test',
    password: 'test123678!'
}

let db = pg(connectionString);

module.exports = {
    db
}

This file is used in the DataAccess file to do some query, like this:

let db = require('../configs/postgresql.config').db;

let getAll = function() {
    return db.manyOrNone('my query')
        .then(function (res) {
            console.log(res);
            return res;
        });
};

Using the pg-promise module is very fast and easy.
But i get in trouble when i try to do the samething with a mysql database.
How can I achieve the same result with the promise-mysql module?

Use something universal, pg-promise is exclusive for PostgreSQL database. There is this awesome called bluebird , which can be integrated into any instance of a function. http://bluebirdjs.com/docs/getting-started.html
