Question

我有一个具有这种结构的Angular 2应用程序：
Structure of my Angular app

我看到有两个模块依赖项文件夹，但我不知道我应该保留哪一个。

这是我的index.js文件：

  const express = require('express');
  const path = require('path');
  const http = require('http');
  const bodyParser = require('body-parser');

  // Get our API routes
  //const api = require('./server/routes/api');

  const app = express();

  // Parsers for POST data
  app.use(bodyParser.json());
  app.use(bodyParser.urlencoded({ extended: false }));

  // Point static path to dist
  app.use(express.static(path.join(__dirname, 'client/portfolio')));

  // Set our api routes
  //app.use('/api', api);

  // Catch all other routes and return the index file
  app.get('*', (req, res) => {
    res.sendFile(path.join(__dirname, 'client/portfolio/src/index.html'));
  });

  /**
   * Get port from environment and store in Express.
   */
  const port = process.env.PORT || '3001';
  app.set('port', port);

  /**
   * Create HTTP server.
   */
  const server = http.createServer(app);

  /**
   * Listen on provided port, on all network interfaces.
   */
  server.listen(port, () => console.log(`API running on localhost:${port}`));

当我启动服务器时，我收到此消息：

在此处加载AppComponent内容...

但它停在这里并且不会渲染Angular应用程序。

index.html文件：

<!DOCTYPE html>
<html>
   <head>
      <title>Angular QuickStart</title>
      <base href="/">

      </script>
   </head>
   <body>
      <my-app>Loading AppComponent content here ...</my-app>
   </body>
</html>

以下是将AngularJS与NodeJS集成的一个很好的示例[open tutorial]

诀窍就在这个块中

 <div id="about-desc">
    <p>
 Lorem ipsum dolor sit <span class="animation">amet</span>, consectetur adipisicing elit. <span class="animation"> Officia reprehenderit</span>, <span class="animation"> sit eligendi</span> deserunt, blanditiis quas porro omnis provident quidem voluptate! Fugit ipsa mollitia, atque commodi asperiores, rerum dicta ratione aut.
    </p>
 </div>

$(document).ready(function () { 
  $(".animation").addClass("animated shake");
});

如何将现有的Angular 2应用程序链接到Nodejs Server？
