webpack和kafka-node集成

问题描述：

我正在尝试将由我编写的Javascript集成到HTML文件中。由于脚本要求卡夫卡节点为了产生类似于this，我试图使用webpack捆绑一切。我正在使用此getting started指南并将其适用于我的特定情况。我改变的唯一的事情是index.js文件，把我的剧本中就有如下：webpack和kafka-node集成

import _ from 'kafka-node'; 

document.write("Starting Javascript Kafka Consumer..."); 

var kafka = require('kafka-node'), 
    Consumer = kafka.Consumer, 
    client = new kafka.Client("127.0.0.1:2181"), 
    consumer = new Consumer(... 

...

我使用相同的配置文件刊登在上面的入门简称链接。我做过npm install --save-dev webpack和npm install --save kafka-node。这是我的输出：

有什么想法？

我也是，刚才。如果我找到解决方案，会回到这里。 –

任何运气@Ricardo？尝试类似的东西，但到目前为止我们无法使用webpack打包node-zookeeper-client。 – 12N

答

该模块的测试写入的方式取决于should作为devDependency。即使母版处于开发模式，父项目中也不安装NPM开发依赖项。刚刚运行：

npm i -D should

即使您没有在您的项目中使用它。这为我解决了这个问题。我的项目还有其他要求，如摩卡已经安装。如果你错过了，你可能需要为多个包做这个。
