webpack和kafka-node集成

我正在嘗試將由我編寫的Javascript集成到HTML文件中。由於腳本要求卡夫卡節點爲了產生類似於this，我試圖使用webpack捆綁一切。我正在使用此getting started指南並將其適用於我的特定情況。我改變的唯一的事情是index.js文件，把我的劇本中就有如下：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門簡稱鏈接。我做過npm install --save-dev webpack和npm install --save kafka-node。這是我的輸出：

我也是，剛纔。如果我找到解決方案，會回到這裏。 –

任何運氣@Ricardo？嘗試類似的東西，但到目前爲止我們無法使用webpack打包node-zookeeper-client。 – 12N

該模塊的測試寫入的方式取決於should作爲devDependency。即使母版處於開發模式，父項目中也不安裝NPM開發依賴項。剛剛運行：

npm i -D should

即使您沒有在您的項目中使用它。這爲我解決了這個問題。我的項目還有其他要求，如摩卡已經安裝。如果你錯過了，你可能需要爲多個包做這個。
