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 🙏

简单的用于node.js的MySql操作方法的集合

Readme

概述

初次学习node.js的服务器端开发,Express是一个很好的框架,但是并没有提供相对应的database的操作方法,之前写了一段时间的PHP,因此根据PHP常用的DB类修改了一个适用于node.js的DB操作方法的集合。

1.安装

npm install mysql-operate

2.初始化

var sql = require('mysql-operate')
sql.constract({
    host: '127.0.0.1',
    user: 'root',
    password: 'root',
    database: 'db_name',
    port: 3306
})

3.使用

1) getAll

let condition = {
    name: 'Tom',
    sex: '男'
}
sql.getAll('tablename', condition, 'id DESC', '0,20')

getAll方法可以传入四个参数:

  • table:表名称(必填)
  • condtion:查询条件(对象,非必填)
  • order:排序方式(非必填,默认 id DESC)
  • limit:限制天剑(非必填, 默认 0,20)

2) getRow

let condition = {
    name: 'Tom',
    sex: '男'
}
sql.getRow('tablename', condition, 'id DESC')

getRow方法可以传入三个参数:

  • table:表名称(必填)
  • condtion:查询条件(对象,非必填)
  • order:排序方式(非必填,默认 id DESC)

3) create

let data = {
    name: 'Tom',
    sex: '男'
}
sql.create('tablename', data)

create方法可以传入两个参数:

  • table:表名称(必填)
  • data:插入数据(对象,必填)

4) update

let data = {
    name: 'Cindy',
    sex: '男'
}
let condition = {
    name: 'Tom'
}
sql.update('tablename', data, condition)

update方法可以传入三个参数:

  • table:表名称(必填)
  • data:插入数据(对象,必填)
  • condition:条件数组(对象)

5) delete

let condition = {
    name: 'Tom'
}
sql.delete('tablename',  condition)

delete方法可以传入三个参数:

  • table:表名称(必填)
  • condition:条件数组(对象,必填)

6) query

sql.query('原生sql')

调用形式

sql.getRow('user', {
    name: 'Tom'
}).then(response => {
//do something
}).catch(err => {
//do something
})
