About

easymysql 基于node-mysql 開發(fā)而來，提供一個(gè)簡(jiǎn)單、高可用的mysql連接基礎(chǔ)庫。主要特性如下：

支持query超時(shí)控制；

可控制的連接池支持，SQL總是盡可能早地被 可用的 空閑連接搶到并執(zhí)行；

支持master-slave模式，基于SHOW VARIABLES LIKE 'READ_ONLY'方式自動(dòng)判斷主庫和從庫，運(yùn)行期間自動(dòng)感知主從切換；

即將支持事務(wù)。

Install

$ npm install easymysql

var Client = require('easymysql');

var mysql = Client.create({

'maxconnections' : 10

});

'host' : '127.0.0.1',

'user' : 'write_user',

'password' : ''

});

mysql.addserver({

'host' : '127.0.0.1',

'user' : 'read_user',

'password' : ''

});

mysql.on('busy', function (queuesize, maxconnections, which) {

// XXX: write log and monitor it

});

mysql.query('SHOW DATABASES', function (error, res) {

console.log(res);

});

}, function (err, rows) {

console.log(rows);

});
