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 🙏

Promisify-wxa

将微信小程序的 API promise 化

微信小程序的 API 大部分是回调风格的:

wx.navigateTo({
  url: 'someUrl',
  success() {
    // 成功回调
  }
})

大多数小程序的框架都会将对应的 API 改为 Promise 风格:

Taro.navigateTo({ url: 'someUrl' })
  .then(res => {
    // 成功回调
  })

如果你不想使用任何框架,可以直接用这个库。这个库只做一件事,就是将微信小程序的 API 代理到一个对象上,并且将相应回调风格的 API 转换成 Promise 风格(见使用方法)。

安装

npm install -S promisify-wxa

使用方法

import promisify from 'promisify-wxa'

App({
  onLaunch() {
    promisify(this) // app 实例上代理了 wx 全部方法,其中回调风格的 API 全部转换成 Promise 风格
  }
})

// 在小程序中可以这样使用
const app = getApp()

app.navigateTo({ url: 'someUrl' })
  .then(res => console.log('it works'))

实现

copy 了 taro 的实现,感谢 MIT 协议。
