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 🙏

针对rax runtime的性能优化插件

支持

插件支持 微信小程序和阿里小程序

原理

rax 运行时实现上,因为无差别事件绑定,会导致的页面滑动卡顿,长列表性能不佳,据此,我们的插件通过去除大量无用事件,解决因此带来的性能瓶颈

目前会被优化的标签有:

<View></View>
<Text></Text>
<Image></Image>

目前会被去除的事件有:

onTouchMove="onTouchMove"
onTouchStart="onTouchStart"
onTouchEnd="onTouchEnd"
onTouchCancel="onTouchCancel"
onLongTap="onLongTap"

onFirstAppear="onViewFirstAppear"
onAppear="onViewAppear"
onDisappear="onViewDisappear"

对于需要使用这些事件的地方,推荐使用div标签作为代替。

效果

性能提升,在中低端机上尤为明显,长列表的性能堪比原生。 数据对比待更新...

使用

插件为build-scripts插件,在rax项目的根目录中的 build.json 中引入即可:

{
  "targets": [
    "miniapp"
  ],
  "plugins": [
    "@ali/build-plugin-rax-app-def",
    "build-plugin-rax-fly"
  ]
}
