Question

因为我是webpack的新手，所以我尝试采用现有的应用程序。所以我设法取得了一些结果，但是我想默认设置（通过启动应用程序）特定页面。（实际上是主页）。因为我使用的是没有顶部导航的路由，而且必须显示的第一页也必须是首页。

webpack.config.js

const webpack = require('webpack');

module.exports = {

    entry: './src/index.js',
    module: {
        rules: [
          {
            test: /\.(js|jsx)$/,
            exclude: /node_modules/,
            use: ['babel-loader']
          } , {
            test: /\.css$/,
            use: [
              { loader: "style-loader" },
              { loader: "css-loader" }
            ]
          } , {
            test: /\.(jpe?g|png|gif|woff|woff2|eot|ttf|svg)(\?[a-z0-9=.]+)?$/,
            loader: 'url-loader?limit=100000' }
        ]
      },
      resolve: {
        extensions: ['*', '.js', '.jsx']
      },
    output: {
      path: __dirname + '/dist',
      publicPath: '/',
      filename: 'bundle.js'
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
      ],
    devServer: {
      contentBase: './dist',
      hot: true,

  }
}

App.js

  render(){
  return (
    <Switch>
      <div>
        <ul>
          <li>
            <Link to="/">Home</Link>
          </li>
          <li>
            <Link to="/about">About</Link>
          </li>
          <li>
            <Link to="/topics">Topics</Link>
          </li>
        </ul>
        <div className='App'>
          <div className='mainContainer'>
            <Route exact path="/" component={Home} />
            <Route exact path="/home" component={Home} />
            <Route path="/about" component={About} />
            <Route path="/topics" component={Topics} />
          </div>
        </div>
      </div>
    </Switch>

也许我做错了事，但是请不要对我不好。正如我上面提到的，我是webpack的新手，所以...如果有人给我一个好的答案，我将感到满意。谢谢。
