NodeJS mysql2蓝鸟吗？

Question

Been testing mysql vs mysql2, seems like 2 has made some improvments however it's not an exact drop in replacement. At the same time Q is a good library which seems easier to integrate with however bluebird seems to take less memory and run faster so...

My current mysql-bluebird connector is as follows and allows for straight forward use of query('SELECT email FROM users.users WHERE id=?',id).then(function(res){var email=res[0][0];});

/* global module, require */
var conf=require('./conf.js').conf;
var mysql = require('mysql');
var Promise = require('bluebird');
var using = Promise.using;
Promise.promisifyAll(require('mysql/lib/Connection').prototype);
Promise.promisifyAll(require('mysql/lib/Pool').prototype);

var pool = mysql.createPool(conf.mysql);

var getConnection = function () {
 return pool.getConnectionAsync().disposer(function (connection) {
 return connection.release();
 });
};
var query = function (command) {
 return using(getConnection(), function (connection) {
 return connection.queryAsync(command);
 });
};
function queryWrapper(q,a){
  if(a){
    return query(mysql.format(q,a));
  }
  else{
    return query(mysql.format(q));
  }
}
module.exports = {
 query: queryWrapper
};

So far my attempts ad doing this with mysql2 haven't panned out.

Does anyone have any insights on how to convert this? Thanks, Jegsar

Answer 1

You can use mysql2-promise . It's a simple wrapper, using q, that promisifies mysql2. If you'd rather use Bluebird, you can look at how this wrapper was created and do it yourself.

Answer 2

node-mysql2 now has Promise api built in , and you can choose which promise implementation you want to use

var mysql = require('mysql2/promise');
mysql.createConnection({
  Promise: require('bluebird'), // if not set, global Promise is used
  user: 'foo',
  password: 'bar',
  database: 'baz'
})
 .then((conn) => conn.query('select 1+1 as test'))
 .then(([rows, fields]) => console.log(rows[0]))
