Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

express-mysql-pool

express middleware for mysql pooling connection 一个能让你更方便连接并操作mysql的express中间件。只使用连接池模式连接mysql,并将连接挂载到request对象上。 (更多数据库连接方式可使用 express-mysql-connection

安装 Install

npm install express-mysql-pool

策略 Strategies

使用连接池进行数据库连接,并且使用的连接会在请求响应后自动释放回连接池。 creates pool of connections on an app instance level, and serves a single connection from pool per request. The connections is auto released to the pool at the response end.

使用 Usage

使用中间件

var mysql = require('mysql'); // 需要引入mysql模块
var myConn = require('express-mysql-connection'); //引入本模块
var dbOptions = {
    host: 'localhost',
    user: 'dbuser',
    password: 'password',
    port: 3306,
    database: 'mydb'
} // 数据库配置
var useConnRoutRs = ['/api', '/test']; // 声明需要使用数据库的路径
app.use(useConnRoutRs, myConn(mysql, dbOptions)); // 使用

// 当然你也可以全局使用: 
// app.use(myConn(mysql, dbOptions));

数据库查询

基本用法

app.get('api/foods', function(req, res, next) {
    var sql = 'SELECT * FROM food';
    // 获取连接
    req.getConnection(function(err, conn) {
        if(!err) {
            // 执行sql查询
            conn.query(sql,function(err, sqlResult) {
                if(!err) {
                    // 响应结果
                    res.json(sqlResult);
                }else {
                    throw err;
                }
            });
        }else {
            throw err;
        }
    });
});
