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 🙏

      Uni(),
      UnoCSS()

  })
}
// vite.config.mts,不支持 HBuilderX

const Uni = uniModule.default || uniModule

export default defineConfig({
  plugins: [
    Uni(),
    UnoCSS()
  ]
})
// uno.config.ts,支持 HBuilderX
import { defineConfig } from 'unocss'
import { presetUni } from '@uni-helper/unocss-preset-uni'

export default defineConfig({
  presets: [
    presetUni()
  ]
})

完整配置示例可参考 uni-helper/vitesse-uni-app

选项

uno

  • 默认值:true

是否启用 @unocss/preset-uno。对于小程序平台,使用基于 @unocss/preset-uno 分叉而来的 @unocss-applet/preset-applet 以获取更佳支持。

默认启用。要禁用,请传递 false

除了传递 boolean 值,你也可以传递 @unocss/preset-uno 以及 @unocss-applet/preset-applet 的选项,具体选项请查看上方提供的文档链接,此时仍视为开启。

remRpx

  • 默认值:true

是否启用 @unocss-applet/preset-rem-rpx

默认启用,将 rpx 转换成 rem(即 mode: "rpx2rem")。要禁用,请传递 false

除了传递 boolean 值,你也可以传递 @unocss-applet/preset-rem-rpx 的选项,具体选项请查看上方提供的文档链接,此时仍视为开启。

attributify

  • 默认值:true

是否启用 @unocss/preset-attributify。对于小程序平台,还会自动启用 @unocss-applet/transformer-attributify 以获取更佳支持。

默认启用,匹配属性,忽略 blockfixed。要禁用,请传递 false

除了传递 boolean 值,你也可以传递 @unocss/preset-attributify 的选项,具体选项请查看上方提供的文档链接,此时仍视为开启。

注意:部分情况下组件库的属性命名可能会与此模式冲突,如果出现样式无效的情况,请尝试关闭此选项,或者设置 prefixedOnly 选项值为 true,只扫描前缀匹配的属性。

import { defineConfig } from 'unocss'
import { isMp } from '@uni-helper/uni-env'
import { presetUni } from '@uni-helper/unocss-preset-uni'

export default defineConfig({
  presets: [
    presetUni({
      attributify: {
        prefixedOnly: true,
      }
    })
  ]
})

示例

默认地,用法与 @unocss/preset-uno 一致,额外支持以下功能。

按平台编写

开箱即用的平台支持,允许你按平台编写相应样式。

<!-- 只在 H5 编译出 mx-auto 类 -->
<div class='uni-h5:mx-auto'></div>

<!-- 只在 APP 编译出 mx-auto 类 -->
<div class='uni-app:mx-auto'></div>

<!-- 只在小程序编译出 mx-auto 类 -->
<div class='uni-mp:mx-auto'></div>

<!-- 只在微信小程序编译出 mx-auto 类,类名也可以写成 uni-mp-weixin:mx-auto -->
<div class='uni-weixin:mx-auto'></div>

<!-- 只在支付宝小程序编译出 mx-auto 类,类名也可以写成 uni-alipay:mx-auto -->
<div class='uni-mp-alipay:mx-auto'></div>
...

你也可以通过自定义 theme.platforms 来自定义平台匹配规则:

// uno.config.ts
import { defineConfig } from 'unocss'
import { presetUni } from '@uni-helper/unocss-preset-uni'

export default defineConfig({
  presets: [
    presetUni()
  ],
  theme: {
    platforms: {
      'wechat': 'mp-weixin', // 支持 uni-wechat,等同于 uni-mp-weixin
      'my-app': 'my-app', // 自定义平台,支持 uni-my-app
    }
  }
})
<!-- 注意:你不能省略 uni- 的类名前缀 -->
<div class='uni-wechat:mx-auto'></div>
<div class='uni-my-app:mx-auto'></div>
platforms = {
  '360': 'mp-360',
  'mp': 'mp',
  'app': 'app',
  'quickapp': 'quickapp',
  'app-plus': 'app-plus',
  'h5': 'h5',
  'mp-360': 'mp-360',
  'mp-alipay': 'mp-alipay',
  'alipay': 'mp-alipay',
  'mp-baidu': 'mp-baidu',
  'baidu': 'mp-baidu',
  'mp-jd': 'mp-jd',
  'jd': 'mp-jd',
  'mp-kuaishou': 'mp-kuaishou',
  'kuaishou': 'mp-kuaishou',
  'mp-lark': 'mp-lark',
  'lark': 'mp-lark',
  'mp-qq': 'mp-qq',
  'qq': 'mp-qq',
  'mp-toutiao': 'mp-toutiao',
  'toutiao': 'mp-toutiao',
  'mp-weixin': 'mp-weixin',
  'weixin': 'mp-weixin',
  'quickapp-webview': 'quickapp-webview',
  'quickapp-webview-huawei': 'quickapp-webview-huawei',
  'quickapp-webview-union': 'quickapp-webview-union'
}
