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

dbfactory主要用于提供数据库连接服务

(1)使用

var db = require('dbfactory');

db('[provider name]', function(err, client) {
	client.query('[sql]', function(err, results, fields) {
	});
})
	

(2)配置

配置文件地址在:'./cfg/settings.js', 参考配置文件内的具体说明

(3)范例

参考'./example/run.js'

querytemplate用来参数化sql语句, 避免拼接sql, 解决sql注入的问题 使用依赖于dbfactory 类似上面的例子 var db = require('dbfactory'); db.compile('select * from some_table where some_key = ?').setInt(0, "1").execute(db, 'provider', function(err, results){ // deal with errs and results });

compile()的参数为一个模板, 其中的参数用?替代. 之后使用setInt, setFloat, setBoolean和setString方式设置参数, 这几个方法的第一个参数为index, 含义是第几个?(start from 0) 第二个参数为参数的值, 字符串或者数值都可以 使用链式调用 例如 db.compile('?,?,?').setInt(0,0).setBoolean(1,'true').setString(2,"value").execute(...)
