## About
`easymysql` 基于[`node-mysql`](https://github.com/felixge/node-mysql) 开发而来，提供一个简单、高可用的mysql连接基础库。主要特性如下：
* 支持query超时控制；
* 可控制的连接池支持，SQL总是尽可能早地被 **可用的** 空闲连接抢到并执行；
* 支持master-slave模式，基于`SHOW VARIABLES LIKE 'READ_ONLY'`方式自动判断主库和从库，运行期间自动感知主从切换；
* 即将支持事务。
## Install
```bash
$ npm install easymysql
```
## Usage
```javascript
var Client = require('easymysql');
var mysql = Client.create({
'maxconnections' : 10
});
mysql.addserver({
'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);
});
// bind params
mysql.query({
sql: 'select * from user where user =:user',
params: {user: 'xxoo'}
}, function (err, rows) {
console.log(rows);
});
```
