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 🙏

export-css-variables

npm version

English | 中文

export-css-variables 是一个用于将 CSS 变量导出到 CSS 文件的工具。它旨在简化在现存旧项目中提取 CSS 变量的过程,并提供一个简单的 CLI 和 API 接口。

安装

你可以通过 npm 或其他包管理器全局安装该工具:

npm i -g @levelii/export-css-variables
yarn global add @levelii/export-css-variables
pnpm add -g @levelii/export-css-variables
bun add -g @levelii/export-css-variables

CLI 使用

安装完成后,你可以使用命令行工具 ecv 来导出 CSS 变量。以下是一些常用命令:

导出 CSS 变量

# global installation
npx ecv -d <搜索css文件路径> -o <导出css文件路径>

# or use npx
npx @levelii/export-css-variables ecv
  • -d : directory 搜索 css 文件路径,该路径下所有 css 文件将被搜索并导出 CSS 变量。
  • -o : output 指定输出文件的路径,将导出的 CSS 变量保存到该文件中。
  • -b : basePath 如果css中存在相对路径引用,该参数会作为 baseurl 进行转换,默认值是 directory 参数。
  • -p : basePathPrefix basepath 的前缀,默认是 @

basePath 和 basePathPrefix 参数可以用于解决 css 中存在相对路径引用的问题。转换例子:

css文件所在目录是 apps/src/pages/component/bar.css, 在 css 中存在这样一个引用 url('../../../images/logo.png'), 如果 basePath 是 apps/src 则提取到的变量值为 url('@/pages/images/logo.png'), 其中的 @ 即 basePathPrefix 参数。

API 使用

该工具同时提供了 API 接口,你可以通过以下方式使用:

import { exportCSSVariables } from '@levelii/export-css-variables'

exportCSSVariables({
  directory: 'path/to/search/css/files',
  output: 'path/to/export/css/file',
  basePath: 'path/to/base/url',
  basePathPrefix: '@'
})
