mysql-promise2

Standard wrapper around MySQL, function names ending with *Async return Bluebird Promises.

I also added a Bluebird Disposer pool.getTransaction() to ease creating chained Promises in a single transaction which gets automatically committed if everythin's ok or rolled back if there is an error.

var Promise = require('bluebird'),
    mysql = require('mysql-promise2'),
    pool = mysql.createPool({
        connectionLimit: 5,
        host: '', user: '', password: '', database: '',
        //debug: ['ComQueryPacket', 'RowDataPacket']
    });
Promise.using(pool.getTransaction(), function (conn) {
    // everything inside is in a transaction
    return pool.queryAsync(
        "SELECT * FROM data WHERE used = 0 ORDER BY last DESC LIMIT 1"
    ).spread(function (rows, cols) {
        var data = rows[0];
        return pool.queryAsync("UPDATE data SET used = 1 WHERE id = ?", [data.id]
            ).then(function () { return data; });
    });
    // end of the transaction
}).then(function (data) {
    // transaction was a COMMIT
}).catch(function () {
    // transaction was a ROLLBACK
});
