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 🙏

让你的微信小程序项目拥有类似与vue的响应式数据的特性,从而让你不用在代码中显式调用setData函数。

  • 如果你的微信微信基础库版本>2.1.1,你可以直接在项目中引入npm包
npm install --save wx-reactdata

//app.js
import 'wx-reactdata'
  • 如果你的项目不支持npm,那么需要你手动引入
//app.js
import './node_modules/wx-reactdata/src/index'

如何使用

在app.js中引入'wx-reactdata'之后,你就可以在页面中更新页面数据

this.$data.name = 'lee'
this.$data.pets[0].type = 'dog'
this.$data.pets = [1,2,3]
this.$data.info.name = 'limei'
this.$data.info = { a: 2 }

// 等同于
this.setData({
  name: 'lee',
  pets: [1,2,3],
  info: { a: 2 }
})

理论上每次对this.$data的属性赋值都会执行一次setData,如上面的代码可能是要执行5次setData,这违背了小程序不能频繁setData的原则。其实这种担心是多余的,它会缓存所有的setData的操作,知道当前队列函数执行完成后才会执行真正的setData操作,也就说上面其实只执行了一次setData操作。
