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 🙏

Weapp Class

🌞 微信小程序原子化 CSS 库

参考 tailwindcss,使用 sass 开发,拿来即用的原子化 CSS 库

使用

直接使用

将 dist 目录下的样式文件按需复制到项目内使用即可;

具体类名参考 tailwindcss 或查看 dist 内的样式文件

使用 NPM

npm i weapp-class

注意:在小程序中使用npm包前,需先构建 npm

/* app.wxss */

@import '../../miniprogram_npm/weapp-class/atomic.min.wxss';
<!-- index.wxml -->

<view class="flex justify-center w-full mt-10 text-center">
  <text class="text-orange">Weapp Class</text>
</view>

删除未使用 css

使用 gulp-uncss,具体步骤如下:

  1. 安装依赖 npm install -D [email protected] [email protected] postcss-uncss
  2. 在项目根目录新增 gulpfile.js
  3. 打开开发者工具右上角“详情”面板,选择“本地设置”,勾选“启用自定义处理命令”,在“预览前预处理”或“上传前预处理”中输入 gulp uncss,这样预览或上传前就会在指定目录生成新的样式文件
  4. 上传代码前引入新的样式文件并注释掉旧的引入即可
// gulpfile.js

const gulp = require('gulp')
const postcss = require('gulp-postcss')
const uncss = require('postcss-uncss')
const path = require('path')

const weappDir = './miniprogram'
const weappClassDir = `${weappDir}/miniprogram_npm/weapp-class`

gulp.task('uncss', gulp.series(function() {
  return gulp.src(path.join(weappClassDir, './atomic.min.wxss'))
    .pipe(postcss([
      uncss({
        html: [`${weappDir}/pages/**/*.wxml`]
      }),
    ]))
    .pipe(gulp.dest(path.join(weappClassDir, 'uncss')))
}))
/* app.wxss */

/* @import '../../miniprogram_npm/weapp-class/atomic.min.wxss'; */
@import '../../miniprogram_npm/weapp-class/uncss/atomic.min.wxss';

定制

源码内所有样式依赖于 sass 的函数指令生成,最终通过 gulp 转换成 css 文件;

你可以根据现有源码开发出自己的 CSS 库:

  • 自定义公共前缀
  • 自定义分隔符
  • 自定义样式名缩写
  • 自定义主题

开发

  1. 将源码克隆到本地 Gitee
  2. 安装 gulp
  3. 修改配置文件 config.js 内的各个配置项,执行 gulp dev 命令
# 进入源码根目录
cd weapp-class

# 安装所有依赖包
npm install

# 执行 gulp 命令
gulp dev

打包

执行 gulp build 命令,即可重新生成样式文件

注意事项

由于微信小程序有自己的响应式单位 rpx,有可能会有 rem 失效的问题,可以使用 page-meta 解决,或者修改配置文件 config.js 内的 rem2rpx 参数进行单位转换
