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 🙏

  width: 100%;
  position: relative;
  font-size: 14px;
  display: inline-block;
  .hm-input__inner {
    -webkit-appearance: none;

    width: 100%;

    &:focus {
      outline: none;
      border-color: #409eff;
    }
  }
}

props处理placeholde, type,name

  • placeholer
<input type="text" class="hm-input__inner" :placeholder="placeholder">
  props: {
    placeholder: {
      type: String,
      default: ''
    }
  }
  • type属性-密码框
    <input
      class="hm-input__inner"
      :placeholder="placeholder"
      :type="type"
      :disabled="disabled"
    >
    type: {
      type: String,
      default: 'text'
    },

禁用按钮-disabled

结构

<div class="hm-input">
  <input
         class="hm-input__inner"
         :class="{'is-disabled': disabled}"
         :placeholder="placeholder"
         :type="type"
         :disabled="disabled"
         >
</div>

js

    disabled: {
      type: Boolean,
      default: false
    }

样式

    &.is-disabled {
      background-color: #f5f7fa;
      border-color: #e4e7ed;
      color: #c0c4cc;
      cursor: not-allowed;
    }

v-model语法糖

  • v-model语法糖
给普通表单元素元素使用v-model
<input type="text" v-model="mes">
<input v-bind:value="mes"  v-on:input="mes= $event.target.value"/>
  
给组件使用v-model指令,实质上相当于给组件传递了value属性以及监听了input事件
<hm-input v-model="msg">
等价与
<hm-input v-bind:value="mes"  v-on:input="mes= arguments[0]"/>
  • html结构
<div class="hm-input">
  <input
         class="hm-input__inner"
         :class="{'is-disabled': disabled}"
         :placeholder="placeholder"
         :type="type"
         :disabled="disabled"
         :value="value"
         @input="handleInput"
         >
</div>

js

  
props: {
  value: [String, Number]
},
methods: {
    handleInput (e) {
      this.$emit('input', e.target.value)
    }
  }

clearable与show-password处理

如果给input组件传入clearable属性,会显示一个清空的按钮,如果传入show-password,则会显示一个用于切换密码显示的处理

  • 基本结构
<span class="hm-input__suffix">
  <i class="hm-input__icon hm-icon-circle-close"></i>
  <i class="hm-input__icon hm-icon-view"></i>
</span>
  • props接收
clearable: {
  type: Boolean,
  default: false
},
showPassword: {
  type: Boolean,
  default: false
}
  • 控制按钮显示和隐藏
<span class="hm-input__suffix">
  <i class="hm-input__icon hm-icon-circle-close" v-if="clearable"></i>
  <i class="hm-input__icon hm-icon-view" v-if="showPassword"></i>
</span>

样式

.hm-input--suffix {
  .hm-input__inner {
    padding-right: 30px;
  }
  .hm-input__suffix {
    position: absolute;
    height: 100%;
    right: 10px;
    top: 0;
    line-height: 40px;
    text-align: center;
    color: #c0c4cc;
    transition: all .3s;
    z-index: 900;

      color: #c0c4cc;
      font-size: 14px;
      cursor: pointer;
      transition: color .2s cubic-bezier(.645,.045,.355,1);
    }
  }
}
  • 控制hm-input--suffix的类名
<div class="hm-input" :class="{'hm-input--suffix': this.clearable || this.showPassword}">

<span class="hm-input__suffix" v-if="this.clearable || this.showPassword">
  • 使用计算属性优化
computed: {
  showSuffix () {
    return this.clearable || this.showPassword
  }
}
  • 注册事件-清空内容和切换密码显示
    clear () {
      // console.log('123')
      this.$emit('input', '')
    }
  • 控制密码显示
data () {
  return {
    // 是否显示密码
    passwordVisible: false
  }
},
  
<input
  class="hm-input__inner"
  :class="{'is-disabled': disabled}"
  :placeholder="placeholder"
  :type="showPassword ? (passwordVisible ? 'text': 'password') : type"
  :name="name"
  :disabled="disabled"
  :value="value"
  @input="handleInput"
  ref="input"
>
    
handlePasswordVisible () {
  // 切换type类型
  this.passwordVisible = !this.passwordVisible
}

其他常见事件的支持

    handleFocus (e) {
      this.$emit('focus', e)
    },
    handleBlur (e) {
      this.$emit('blur', e)
    },
    handleChange (e) {
      this.$emit('change', e.target.value)
    }

switch组件

参数支持

| 参数名称 | 参数描述 | 参数类型 | 默认值 | | ------------- | -------------------- | -------- | ------ | | v-model | 双向绑定 | 布尔类型 | false | | name | name属性 | string | text | | activeColor | 自定义的激活的颜色 | string | | | inactiveColor | 自定义的不激活的颜色 | string | |

事件支持

| 事件名称 | 事件描述 | | -------- | ------------------ | | change | change时触发的事件 |

基本结构

  • 页面
<template>
  <label class="hm-switch">
    <span class="hm-switch__core">
      <span class="hm-switch__button"></span>
    </span>
  </label>
</template>
  • 样式
.hm-switch {
  display: inline-flex;
  align-items: center;
  position: relative;
  font-size: 14px;
  line-height: 20px;
  height: 20px;
  vertical-align: middle;
  .hm-switch__core {
    margin: 0;
    display: inline-block;
    position: relative;
    width: 40px;
    height: 20px;
    border: 1px solid #dcdfe6;
    outline: none;
    border-radius: 10px;
    box-sizing: border-box;
    background: #dcdfe6;
    cursor: pointer;
    transition: border-color .3s,background-color .3s;
    vertical-align: middle;
    .hm-switch__button {
      position: absolute;
      top: 1px;
      left: 1px;
      border-radius: 100%;
      transition: all .3s;
      width: 16px;
      height: 16px;
      background-color: #fff;
    }
  }
}

v-mode双向绑定

  • 接收value值
props: {
  value: {
    type: Boolean,
    default: false
  }
},
  • 注册点击事件
<div class="hm-switch" @click="handleClick">
  • 事件处理程序
methods: {
  handleClick () {
    this.$emit('input', !this.value)
  }
}
  • 选中样式
.hm-switch.is-checked {
  .hm-switch__core {
    border-color: #409eff;
    background-color: #409eff;
    .hm-switch__button {
      transform: translateX(20px);
    }
  }
}
  • 控制选中样式
<div class="hm-switch" @click="handleClick" :class="{'is-checked': value}">

自定义颜色

在使用switch时,希望能够自定义开关的颜色

<hm-switch
  v-model="value"
  active-color="#13ce66"
  inactive-color="#ff4949">
</hm-switch>
  • props接收
activeColor: {
  type: String,
  default: ''
},
inactiveColor: {
  type: String,
  default: ''
}
  • 封装设置颜色的方法
setColor () {
  if (this.activeColor || this.inactiveColor) {
    let color = this.value ? this.activeColor : this.inactiveColor
    this.$refs.core.style.borderColor = color
    this.$refs.core.style.backgroundColor = color
  }
}
  • 页面一进入调用
mounted () {
  // 设置颜色
  this.setColor()
},
  • 改变状态后调用
async handleClick () {
  this.$emit('input', !this.value)
  // 改变input框的值
  await this.$nextTick()
  this.setColor()
},

name属性支持

用户在使用switch组件的时候,实质上是当成表单元素来使用的。因此可能会用到组件的name属性。因此需要在switch组件中添加一个checkbox,并且当值改变的时候,也需要设置checkbox的value值

  • 结构
<input
  class="hm-switch__input"
  type="checkbox"
>
  • 样式
.hm-switch__input {
  position: absolute;
  width: 0;
  height: 0;
  opacity: 0;
  margin: 0;
}
  • name属性的支持
name: {
  type: String,
  default: ''
}
  • 控制checkbox的值与value同步
  mounted () {
    this.$refs.input.checked = this.value
  },
  methods: {
    async handleChange () {
      this.$emit('input', !this.value)
      // 修改checkbox的值
      await this.$nextTick()
      this.$refs.input.checked = this.value
    }
  }

radio组件

前置知识点

radio的基本使用

参数支持

| 参数名称 | 参数描述 | 参数类型 | 默认值 | | -------- | --------------- | ------------------- | ------ | | v-model | 双向绑定 | 布尔类型 | false | | label | 单选框的value值 | string,num,boolean | '' | | name | name属性 | string | |

      }
    }
  }
  .hm-radio__label {
    color: #409eff;
  }
}

label与插槽的处理

  • props接收
props: {
  label: {
    type: String,
    default: ''
  },
  name: {
    type: String,
    default: ''
  }
}
  • 处理插槽
<span class="hm-radio__label">
  <slot></slot>
  <!-- 如果没有插槽内容,那么label就是内容 -->
  <template v-if="!$slots.default">{{label}}</template>
</span>

v-model处理

  • 接收props数据
name: {
  type: String,
  default: ''
},
value: {
  type: [String, Boolean, Number],
  default: ''
}
  • 结构
<input
  class="hm-radio__original"
  type="radio"
  :name="name"
  value="label"
  v-model="model"
>
  • 提供计算属性
computed: {
  model: {
    get () {
      return this.value
    },
    set (value) {
      this.$emit('input', value)
    }
  }
},
  • 控制选中样式
<label class="hm-radio" :class="{'is-checked': model === label}">

radio-group组件

使用radio组件的缺点,需要给每个组件都绑定v-mode,可以使用radio-group包裹

前置知识

provide与inject

基本结构

结构

<template>
  <div class="radio-group">
    <slot></slot>
  </div>
</template>

数据

export default {

      RadioGroup: this
    }
  },
  props: {
    value: null
  }
}

修改radio组件

  • 接收inject
inject: {
  RadioGroup: {
    default: ''
  }
},
  • 计算属性判断是否包裹在group中
// 判断包裹在group中
isGroup () {
  return !!this.RadioGroup
}
  • 修改代码
model: {
  get () {
    return this.isGroup ? this.RadioGroup.value : this.value
  },
  set (value) {
    this.isGroup ? this.RadioGroup.$emit('input', value) : this.$emit('input', value)
  }

封装成UI组件库

目录调整

  • 根目录创建两个文件夹packagesexamples
packages: 用于存放所有的组件
examples: 用于进行测试,把src改成examples
  • 把components中所有的组件放入到packages中

  • 把fonts放到packages中

  • 删除原来的src目录

vue.config.js配置

新增vue.config.js配置

const path = require('path')
module.exports = {
  pages: {
    index: {
      entry: 'examples/main.js',
      template: 'public/index.html',
      filename: 'index.html'
    }
  },
  // 扩展 webpack 配置,使 packages 加入编译
  chainWebpack: config => {
    config.module
      .rule('js')
      .include.add(path.resolve(__dirname, 'packages')).end()
      .use('babel')
      .loader('babel-loader')
      .tap(options => {
        // 修改它的选项...
        return options
      })
  }
}
  • 统一导出packages中所有的组件
// 统一导出
// 导入颜色选择器组件
import Button from './button'
import Dialog from './dialog'
import Input from './input'
import Checkbox from './checkbox'
import Radio from './radio'
import RadioGroup from './radio-group'
import Switch from './switch'
import CheckboxGroup from './checkbox-group'
import Form from './form'
import FormItem from './form-item'
import './fonts/font.scss'

// 存储组件列表
const components = [
  Button,
  Dialog,
  Input,
  Checkbox,
  Radio,
  RadioGroup,
  Switch,
  CheckboxGroup,
  Form,
  FormItem
]

// 定义 install 方法,接收 Vue 作为参数。如果使用 use 注册插件,则所有的组件都将被注册
const install = function (Vue) {
  // 遍历注册全局组件
  components.forEach(component => {
    Vue.component(component.name, component)
  })
}

// 判断是否是直接引入文件,如果是,就不用调用 Vue.use()
if (typeof window !== 'undefined' && window.Vue) {
  install(window.Vue)
}

// 导出的对象必须具有 install,才能被 Vue.use() 方法安装
export default {
  install
}

测试

在examples中的main.js中进行导入测试

import Vue from 'vue'
import App from './App.vue'

import HeimaUI from '../packages'

Vue.use(HeimaUI)

Vue.config.productionTip = false

new Vue({
  render: h => h(App)
}).$mount('#app')
