Vue Custom Element无法在Dist中构建独立的JS文件

Question

我按照说明在这里注册和使用自定义元素:

https://alligator.io/vuejs/custom-elements/

我正在使用Vue的标准Webpack模板.

我跑的时候

npm run build

我希望在dist目录中获得一个名为element.js的打包Web组件文件.但是没有任何事情发生.有谁知道是否需要额外的步骤？文档没有说清楚.

这在我的项目中产生了以下文件:

<template>
  <div id="app">
    <example myProp="I can pass props!"></example>

  </div>
</template>

<script>
import Example from './components/example.Vue'

export default {
  name: 'app',
  components: {
    Example
  }
}
</script>

<style>
</style>

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import vueCustomElement from 'vue-custom-element'

Vue.config.productionTip = false

Vue.use(vueCustomElement);
/* eslint-disable no-new */

import Example from './components/Example.vue';

// Configure Vue to ignore the element name when defined outside of Vue.
Vue.config.ignoredElements = [
    'example-component'
];

// Enable the plugin
Vue.use(vueCustomElement);

// Register your component
Vue.customElement('example-component', Example, {
    // Additional Options: https://github.com/karol-f/vue-custom-element#options
});


new Vue({
  el: '#app',
  template: '<App/>',
  components: { App }
})

组件/ example.vue

<template>
  <p>Dynamic prop value: {{myProp}}</p>
</template>

<script>
export default {
  props: ['myProp']
}
</script>

的package.json

{
  "name": "example",
  "version": "1.0.0",

  },
  "browserslist": [
    "> 1%",

    "not ie <= 8"
  ]
}

包含自定义元素和vue库的脚本文件后,我的index.html如下所示:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>example</title>
    <script src="vue/dist/vue.min.js"></script>
    <script src="vue-custom-element/dist/vue-custom-element.js"></script>

  </head>

  <body>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>

</html>

文档和 alligator.io 文章没有解释它，但为了工作，vue-custom-element 仍然需要 Vue.js 和vue-custom-element库。

所以你必须使用<script>webpack 在index.html.

找到一个教程提到： http: //vuetips.com/vue-web-components

此实现需要将 Vue.js 核心文件和 vue-custom-element 库包含在您的页面中。

它还提到https://github.com/kartsims/vue-customelement-bundler这是一个将所有内容构建到单个.js文件中的模板。
