webpack 打包vue代码，编译出来的代码是module.exports...形式，浏览器无法识别

Question

在electron-vue项目中，我想写一个vue的页面作为webview，我在项目根目录建立了webview文件夹存放vue页面，打包的文件输出到 wv 文件夹，在.electron-vue文件夹中增加了webpack.webview.config.js

webpack.webview.config.js

'use strict'

process.env.BABEL_ENV = 'webview'

const path = require('path')
const { dependencies } = require('../package.json')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const { VueLoaderPlugin } = require('vue-loader')

let whiteListedModules = ['vue']

let webviewConfig = {
  devtool: '#cheap-module-eval-source-map',
  entry: {
    print: path.join(__dirname, '../webview/print.js')
  },
  externals: [
    ...Object.keys(dependencies || {}).filter(d => !whiteListedModules.includes(d))
  ],
  module: {
    rules: [
      {
        test: /\.(js|vue)$/,
        enforce: 'pre',
        exclude: /node_modules/,
        use: {
          loader: 'eslint-loader',
          options: {

      },

module.exports = webviewConfig

.babelrc

{
  "comments": false,
  "env": {
    "test": {
      "presets": [
        ["env", {
          "targets": { "node": 7 }
        }],
        "stage-0"
      ],
      "plugins": ["istanbul"]
    },
    "main": {
      "presets": [
        ["env", {
          "targets": { "node": 7 }
        }],
        "stage-0"
      ]
    },
    "renderer": {
      "presets": [
        ["env", {
          "modules": false
        }],
        "stage-0"
      ]
    },
    "webview": {
      "presets": ["babel-preset-env", "vue"]
    },
    "web": {
      "presets": [
        ["env", {

        }],
        "stage-0"
      ]
    }
  },
  "plugins": ["transform-runtime"]
}

webview中的文件

printer.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div id="pw">just html</div>
</body>
</html>

print.js

import Vue from 'vue'
import axios from 'axios'

import pw from './pw'

if (!process.env.IS_WEB) Vue.use(require('vue-electron'))
Vue.http = Vue.prototype.$http = axios
Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  components: { pw },
  template: '<pw/>'
}).$mount('#pw')

pw.vue

<template>
    <div>this is vue page</div>
</template>

<script>
  export default {
    name: 'pw'
  }
</script>

<style scoped>

</style>

打包后启动项目，webview里面的内容依然是just html, 没有变成 this is vue page，我查看了wv文件夹中打包好的js，是module.exports...这样的形式，不是es5，是不是这个原因，浏览器识别不了

我是不是哪里配置有问题，如何才能打包出浏览器能识别的js代码

如知方法，请告知，感谢

Answer 1

你的webpack配置的output.libraryTarget不是commonjs2嘛，出来的当然是module.exports啦。

Answer 2

你需要把libraryTarget设置去掉，这样webpack才不会把js文件包装成commonjs格式。
