javascript - Angular 2 缓慢的初始加载

当我启用跨源资源共享时，我的应用需要 8-9 秒才能加载。当它被禁用时需要 1-2 秒。我真的很陌生。任何想法可能是主要问题？以及如何加快速度？该项目处于非常早期的阶段，8 秒的时间真的很长，因为应用程序现在没有发出任何数据请求。

这是我的 index.html

<!DOCTYPE html>
<html>

  <head>
    <script src="https://unpkg.com/zone.js@0.6.21/dist/zone.js"></script>
    <script src="https://unpkg.com/reflect-metadata@0.1.3/Reflect.js"></script>
    <script src="https://unpkg.com/systemjs@0.19.31/dist/system.js"></script>
    <script src="config.js"></script>
     <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
            <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>


    <script>
    System.import('app/js/bootstrap')
      .catch(console.error.bind(console));
  </script>
   <script src="app/js/xml2json.js"></script>
    <script src="app/js/div.js"></script>
        <script src="app/js/divY.js"></script>

    <style>
  body,html{width:100%;height:100%;padding:5px;margin:0;}

  </style>
  <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="//cdn.jsdelivr.net/interact.js/1.2.6/interact.min.js"></script>
  </head>


  <body>
    <app>
    loading...
  </app>
  </body>

</html>

这是我的 config.js

System.config({
  //use typescript for compilation
  transpiler: 'typescript',
  //typescript compiler options
  typescriptOptions: {
    emitDecoratorMetadata: true
  },
  paths: {
    'npm:': 'https://unpkg.com/'
  },
  //map tells the System loader where to look for things
  map: {
    'app': "./app",
    'ng2-translate': 'npm:ng2-translate',
    '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
    '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
    '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
    '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
    '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
    '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
    '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
    '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

    '@angular/core/testing': 'npm:@angular/core/bundles/core-testing.umd.js',
    '@angular/common/testing': 'npm:@angular/common/bundles/common-testing.umd.js',
    '@angular/compiler/testing': 'npm:@angular/compiler/bundles/compiler-testing.umd.js',
    '@angular/platform-browser/testing': 'npm:@angular/platform-browser/bundles/platform-browser-testing.umd.js',
    '@angular/platform-browser-dynamic/testing': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic-testing.umd.js',
    '@angular/http/testing': 'npm:@angular/http/bundles/http-testing.umd.js',
    '@angular/router/testing': 'npm:@angular/router/bundles/router-testing.umd.js',

    'rxjs': 'npm:rxjs',
    'typescript': 'npm:typescript@2.0.2/lib/typescript.js'
  },
  //packages defines our app package
  packages: {
    app: {
      main: './bootstrap.ts',
      defaultExtension: 'js'
    },
    rxjs: {
      defaultExtension: 'js'
    },
    'ng2-translate': {
      defaultExtension: 'js'
    }
  }


});

最佳答案

我解决了。这是工作文件。我从 map 中删除了 rxjs 并将其添加到路径

System.config({
  //use typescript for compilation
  transpiler: 'typescript',
  //typescript compiler options
  typescriptOptions: {
    emitDecoratorMetadata: true
  },
  paths: {
    'npm:': 'https://unpkg.com/',
    'rxjs*': 'https://unpkg.com/@reactivex/rxjs@5.0.0-beta.12/dist/global/Rx.js'
  },
  //map tells the System loader where to look for things
  map: {
    'app': "./app",
    'ng2-translate': 'npm:ng2-translate',
    '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
    '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
    '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
    '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
    '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
    '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
    '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
    '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

    '@angular/core/testing': 'npm:@angular/core/bundles/core-testing.umd.js',
    '@angular/common/testing': 'npm:@angular/common/bundles/common-testing.umd.js',
    '@angular/compiler/testing': 'npm:@angular/compiler/bundles/compiler-testing.umd.js',
    '@angular/platform-browser/testing': 'npm:@angular/platform-browser/bundles/platform-browser-testing.umd.js',
    '@angular/platform-browser-dynamic/testing': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic-testing.umd.js',
    '@angular/http/testing': 'npm:@angular/http/bundles/http-testing.umd.js',
    '@angular/router/testing': 'npm:@angular/router/bundles/router-testing.umd.js',

    // 'rxjs':  'https://unpkg.com/rxjs@5.0.0-beta.12',
    'typescript': 'npm:typescript@2.0.2/lib/typescript.js'
  },
  //packages defines our app package
  packages: {
    app: {
      main: './bootstrap.ts',
      defaultExtension: 'js'
    },
    rxjs: {
      defaultExtension: 'js'
    },
    'ng2-translate': {
      defaultExtension: 'js'
    }
  }


});
