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 🙏

3.Configuration

模块自带的一些配置信息:

  • Code List 1:
{
    host:'localhost',           //mysql host
    port:3306,                  //mysql port
    database:'test',            //mysql dbname
    user:'root',                //mysql username
    password:'',                //mysql password
    debug:false,                //true:使用 debug 模块输出 生成的sql语句,默认使用 DEBUG=SQL
    showSql:false,              //true:输出本模块生成的sql语句
    pool:{
        connectionLimit:10,     //链接池的配置
        queueLimit:0,
        waitForConnections:true
    }
}

在初始化的时候,可以通过传入的参数覆盖这些默认值

  • Code List 2:
var C = {
    host:'192.168.1.1',
    database:'test',
    username:'root',
    password:'root',
};
var M = require('yf-fpm-dbm')(C);

4.Useage

find
  • Code List 3:
// M 的初始化代码请参看 Code List:2
var arg = {
 table: "test",
 condition: "delflag=0",
 fields: "id,article,ptags,product"
};
M.find(arg, function(error, data){
  if(error){
   // do error here
  }else{
    // do success here
  }
});
first
  • Code List 4:
// M 的初始化代码请参看 Code List:2
var arg = {
 table: "test",
 condition: "delflag=0",

};
M.first(arg, function(error, data){
  if(error){
   // do error here
  }else{
    // do success here
  }
});
//condition 字段接受各种格式
//比如下面的格式同样支持
var arg = {
    table: "api_app",
    condition: [
      ['appid' , '=' , '10001'],
      "appkey = '45883198abcdc109'",
      ['or',['appname' ,'=','DEV_Activity']]
    ],
    fields: "id,appid,appname,apptype"
};
//最终解析出来的语句是这样的:
// where ( 1 = 1  and appid='10001' and appkey = '45883198abcdc109' or appname='DEV_Activity') and delflag = 0
