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 🙏

Mongoing

适合用于云函数的mongodb中间件

  • 连接数据库,提取collection
  • 函数逻辑结束自动关闭数据库连接

使用方法

搭配aliyun-function-compatfcapi使用

数据库连接地址从mongoing第二个参数获取,如果未指定这个参数,则从环境变量MONGODB获取,

如果环境变量未指定,则使用mongodb://127.0.0.1:27017/mongoing

连接成功后,会自动获取所有collection并转换成对象表附加到最后一个参数

如果需要使用未使用过的集合,并且连接地址不通过第二个参数设置,可以在第二个参数指定collection数组

或者在第三个参数指定

可以通过访问__client__db获取客户端连接对象和DB对象

const mongoing = require('mongoing')
const fcapi = require('fcapi')

exports.handler = fcapi(mongoing(async (event, context, {__client, __db, users}) => {
    // 客户端连接
    __client

    // db
    __db

    // collection
    users
}))

// 指定连接地址
mongoing(callback, url)

// 指定collection
mongoing(callback, ['users', 'posts'])

// 指定连接地址和数组
mongoing(callback, url, ['users'])
