webpack配置

var webpack = require('webpack');
var path = require('path');

module.exports = {
    entry: './public/js/app.js',
    output: {
        path: path.join(__dirname, 'dist'),
        filename: 'bundle.js',
        publicPath: '/static/',
        vendor: ['jquery', 'backbone', 'underscore']
    },
    plugins: [
        new webpack.ProvidePlugin({
            $: "jquery",
            Backbone: "backbone",
            _: "underscore"
        }),
        new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.js')
    ]

回复内容：

var fs   = require("fs");
var path = require('path');

下面的path模块就没问题，fs直接就报错了，什么情况？

你先告诉我:

为什么前端项目要引用 fs 模块？
