Question

我遇到了使firebase 3.0.1正常工作的问题。我觉得这与我的webpack设置有关。我的文件在下面。使用webpack dev服务器运行我的应用程序时出现错误：

未捕获的TypeError：firebase.initializeApp不是函数

有趣的是，如果我在debugger;之后放置var firebase = require('firebase');或断点，它似乎是一个空对象。

webpack.config.js

const webpack = require("webpack");

module.exports = {
    entry: './src/index.js',
    output: {
        path: 'public',
        filename: 'bundle.js'
    },
    module: {
        loaders: [{
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'babel-loader?presets[]=es2015&presets[]=react'
        }]
    },
    plugins: process.env.NODE_ENV === 'production' ? [
        new webpack.optimize.DedupePlugin(),
        new webpack.optimize.OccurrenceOrderPlugin(),
        new webpack.optimize.UglifyJsPlugin()
    ] : []
};

index.js

var firebase = require('firebase');

var config = {

    databaseURL: "https://burn-56840.firebaseio.com",
    storageBucket: "burn-56840.appspot.com"
};
firebase.initializeApp(config);

我有same problem，虽然有一个简单的解决方法：

var firebase = require('firebase/app');

通过这种方式，您可以获得“真正的”firebase模块。但是，您现在必须要求您需要的每个模块，以便正确加载，如下所示：

var firebase = require('firebase/app');
// all 3 are optional and you only need to require them at the start
require('firebase/auth');
require('firebase/database');
require('firebase/storage');

在我看来，当前的初始化代码有问题，看它应该工作的来源;但又一次，有点像你，我正在使用browserify，并没有在它之外测试，所以它可能是相关的。
