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 🙏

gent-css

gentcss是一种类似BEM的css命名规范, postcss-gentcss是一个postcss插件,用来将css代码转换为gentcss规范。

gentcss命名规范

命名分为四部分:组件、节点、角色、状态, 每部分都采用驼峰命名方式,只能包含字符数字。

.libName-componentName-elementName {
  /**/
}

.libName-componentName-elementName.libName-is-roleName {
  /**/
}

.libName-componentName-elementName.libName-has-stateName {
  /**/
}

书写

编写时,类名用两个中划线(--)分割,左边标识这个类名是gentcss的哪一种,右边标识对应的名字。

  • .comp--componentName: 组件
  • .elem--elementName: 节点,必须包含在组件内,为组件的直接子元素
  • .is--roleName: 角色
  • .has--stateName: 状态
  • .sel--componentName-elementName: 直接生产节点选择器,不用包含在组件内

实例

输入:

.comp--componentName {
  background: #fff;

  .elem--elementName {
    line-height: 24px;

    &.is--roleNameA {
      background: red;
    }

    &.is--roleNameB {
      background: blue;
    }

    &.has--stateName {
      cursor: not-allowed;
    }
  }
}

.sel--componentName-elementName {
  line-height: 24px;

  &.has--stateName {
    cursor: not-allowed;
  }
}

输出:

.gent-componentName {
  background: #fff
}

.gent-componentName-elementName {
  line-height: 24px;

  &.gent-is-roleNameA {
    background: red;
  }

  &.gent-is-roleNameB {
    background: blue;
  }

  &.gent-has-stateName {
    cursor: not-allowed;
  }
}

.gent-componentName-elementName {
  line-height: 24px;

  &.gent-has-stateName {
    cursor: not-allowed;
  }
}
