Vue–Es6转Es5

核心部署:babel-loader

部署过程:

首先是加载Es5

npm install --save-dev babel-loader@7 babel-core babel-preset-es2015

然后是配置webpack.config.js

const path = require('path');

module.exports = {
    entry: './src/main.js',
    output:{
        path: path.resolve(__dirname,'dist'),
        filename: 'bundle.js',
        publicPath: 'dist/'
  },

    module: {
        rules: [
            {
                test: /\.css$/,
                use: [ 'style-loader', 'css-loader' ]
            },
            {
                test: /\.(png|jpg|gif)$/,
                use: [
                    {
                        loader: 'url-loader',
                        options: {
                            limit: 500
                        }
                    }
                ]
            },
            {
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['es2015']
                    }
                }
            },
            {
                test: /\.less$/,
                use: [{
                    loader: "style-loader" // creates style nodes from JS strings
                }, {
                    loader: "css-loader" // translates CSS into CommonJS
                }, {
                    loader: "less-loader" // compiles Less to CSS
                }]
            }
        ]
    }
}
