打造自己的前端组件库(奶妈版，超详细)

打造自己的前端组件库

demo是开源的，自己上npm 或者 github 上都能搜到
@mhfwork/yt-ui

新建vue项目(sass + js + vue2)

vue create yt-ui	
1

修改文件目录(如下)

修改： 1.src 更名 examples; 2. src/components移动到项目最外层；3.vue.config.js更改入口文件

// vue.config.js
1

const {defineConfig} = require('@vue/cli-service')
module.exports = defineConfig({
    transpileDependencies: true,
    pages: {
        index: {
            entry: 'examples/main.js',
            template: 'public/index.html',
            filename: 'index.html'
        }
    }
})

编写ytDemo组件并在app.vue中使用

新建文件目录结构如上图：

 // components/demo/index.js
    
    import ytDemo from "./src/main.vue";
    
    ytDemo.install = (Vue) => {
      Vue.component(ytDemo.name, ytDemo);
    };
    
    export default ytDemo;

    // components/src/main.vue
    <!--
     * @Description: main 页面
     * @Author: mhf
     * @Date: 2023/10/21
    -->
    <template>
      <div>
        <div class="a">
          a
          <div class="b">b</div>
        </div>
      </div>
    </template>
    
    <script>
    export default {
      name: "ytDemo",
      components: {},
      props: {},
      computed: {},
      watch: {},
      filters: {},
      data() {
        return {};
      },
      methods: {},
      created() {},
      mounted() {},
      destroyed() {},
    };
    </script>
    
    <style lang="scss" scoped>
    .a {
      width: 200px;
      height: 200px;
      border: 1px solid red;
    
      .b {
        width: 100px;
        height: 100px;
        border: 1px solid green;
      }
    }
    </style>
    
    

    // example/main.js
    
    import Vue from 'vue'
    import App from './App.vue'
    
    import ytDemo from "../components/ytDemo";
    Vue.use(ytDemo)
    
    Vue.config.productionTip = false
    
    new Vue({
      render: h => h(App),
    }).$mount('#app')

根据如上步骤则出现如下效果

---

打包

// components/index.js

// 整个包的入口
// 统一导出
import ytComp from "./ytComp";
import ytDemo from "./ytDemo";
const components = [
    ytComp,
    ytDemo,
]
// 定义install方法
const install = function (Vue) {
    // 注册所有的组件
    components.forEach(component => {
        Vue.component(component.name, component)
    })
}
// 判断是否直接引入文件，如果是，就不用调用Vue.use()
if (typeof window !== 'undefined' && window.Vue) {
    install(window.Vue)
}
// 导出install方法
export default {
    install,
    ytDemo,
    ytComp
}

发布流程

todo: 更新 readeMe.md、package.json版本号   
 1. npm run lib   
 2. npm get registry 
 3. npm login     					// 登陆自己的npm账号，没有请自行注册
 4. npm publish --access public		// 正常的话 npm publish 即可，因本项目中使用@mhfwork/xxx 需注明是public库

使用发布成功的组件库

新项目中

npm i @mhfwork/yt-ui

main.js中注册	

    import ytComp from "@mhfwork/yt-ui/components/ytComp";
    import ytDemo from "@mhfwork/yt-ui/components/ytDemo";
    Vue.use(ytComp)
    Vue.use(ytDemo)

Vue文件中使用

<template>
  <div class="home">
    <yt-comp page-name="aaahahah"/>
    <yt-demo />
  </div>
</template>

<script>
// @ is an alias to /src

export default {
  name: 'HomeView',
  components: {
