Ng服务的工作是为我们的应用程序的开发目的服务。生产方面呢?如果我们看看我们的包装。Json文件，我们可以看到有我们可以使用的脚本:

"scripts": {
  "ng": "ng",
  "start": "ng serve",
  "build": "ng build --prod",
  "test": "ng test",
  "lint": "ng lint",
  "e2e": "ng e2e"
},

构建脚本使用Angular CLI的ng build，并带有——prod标志。我们现在试试。我们有两种方法:

#使用NPM脚本

npm run build

#直接使用cli

ng build --prod

这次我们得到了四个文件而不是五个。——prod标志告诉Angular把我们的应用缩小很多。

2.0.1 Final using Gulp (TypeScript - Target: ES5)

前设置

npm安装(在cmd中运行时目录是projectFolder)

捆绑销售的步骤

运行bundle(当目录为projectFolder时在cmd下运行) bundle被生成到projectFolder / bundles /

输出

bundles/dependencies.bundle.js[大小:~ 1 MB(尽可能小)] 包含RXJS和angular依赖项，而不是整个框架 bundle /app.bundle.js[大小:取决于你的项目，我的是~ 0.5 MB] 包含您的项目

文件结构

projectFolder / app /(所有组件、指令、模板等) projectFolder / gulpfile.js

var gulp = require('gulp'),
  tsc = require('gulp-typescript'),
  Builder = require('systemjs-builder'),
  inlineNg2Template = require('gulp-inline-ng2-template');

gulp.task('bundle', ['bundle-app', 'bundle-dependencies'], function(){});

gulp.task('inline-templates', function () {
  return gulp.src('app/**/*.ts')
    .pipe(inlineNg2Template({ useRelativePaths: true, indent: 0, removeLineBreaks: true}))
    .pipe(tsc({
      "target": "ES5",
      "module": "system",
      "moduleResolution": "node",
      "sourceMap": true,
      "emitDecoratorMetadata": true,
      "experimentalDecorators": true,
      "removeComments": true,
      "noImplicitAny": false
    }))
    .pipe(gulp.dest('dist/app'));
});

gulp.task('bundle-app', ['inline-templates'], function() {
  // optional constructor options
  // sets the baseURL and loads the configuration file
  var builder = new Builder('', 'dist-systemjs.config.js');

  return builder
    .bundle('dist/app/**/* - [@angular/**/*.js] - [rxjs/**/*.js]', 'bundles/app.bundle.js', { minify: true})
    .then(function() {
      console.log('Build complete');
    })
    .catch(function(err) {
      console.log('Build error');
      console.log(err);
    });
});

gulp.task('bundle-dependencies', ['inline-templates'], function() {
  // optional constructor options
  // sets the baseURL and loads the configuration file
  var builder = new Builder('', 'dist-systemjs.config.js');

  return builder
    .bundle('dist/app/**/*.js - [dist/app/**/*.js]', 'bundles/dependencies.bundle.js', { minify: true})
    .then(function() {
      console.log('Build complete');
    })
    .catch(function(err) {
      console.log('Build error');
      console.log(err);
    });
});

projectFolder / package。json(与快速入门指南相同，只是显示了捆绑所需的devDependencies和npm脚本)

{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    ***
     "gulp": "gulp",
     "rimraf": "rimraf",
     "bundle": "gulp bundle",
     "postbundle": "rimraf dist"
  },
  "license": "ISC",
  "dependencies": {
    ***
  },
  "devDependencies": {
    "rimraf": "^2.5.2",
    "gulp": "^3.9.1",
    "gulp-typescript": "2.13.6",
    "gulp-inline-ng2-template": "2.0.1",
    "systemjs-builder": "^0.15.16"
  }
}

projectFolder / systemjs.config.js(与快速入门指南相同，不再可用)

(function(global) {

  // map tells the System loader where to look for things
  var map = {
    'app':                        'app',
    'rxjs':                       'node_modules/rxjs',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    '@angular':                   'node_modules/@angular'
  };

  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'app/boot.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { defaultExtension: 'js' }
  };

  var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/forms',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/router-deprecated',
    '@angular/testing',
    '@angular/upgrade',
  ];

  // add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
  packageNames.forEach(function(pkgName) {
    packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
  });

  var config = {
    map: map,
    packages: packages
  };

  // filterSystemConfig - index.asp's chance to modify config before we register it.
  if (global.filterSystemConfig) { global.filterSystemConfig(config); }

  System.config(config);

})(this);

projetcFolder / dist-systemjs.config.js(刚刚显示了与systemjs.config.json的区别)

var map = {
    'app':                        'dist/app',
  };

projectFolder / index.html(生产)——脚本标记的顺序很关键。将dist-systemjs.config.js标记放在bundle标记之后仍然允许程序运行，但是依赖包将被忽略，依赖项将从node_modules文件夹中加载。

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8"/>
  <meta name="viewport" content="width=device-width, initial-scale=1"/>
  <base href="/"/>
  <title>Angular</title>
  <link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>

<my-app>
  loading...
</my-app>

<!-- Polyfill(s) for older browsers -->
<script src="node_modules/core-js/client/shim.min.js"></script>

<script src="node_modules/zone.js/dist/zone.min.js"></script>
<script src="node_modules/reflect-metadata/Reflect.js"></script>
<script src="node_modules/systemjs/dist/system.js"></script>

<script src="dist-systemjs.config.js"></script>
<!-- Project Bundles. Note that these have to be loaded AFTER the systemjs.config script -->
<script src="bundles/dependencies.bundle.js"></script>
<script src="bundles/app.bundle.js"></script>

<script>
    System.import('app/boot').catch(function (err) {
      console.error(err);
    });
</script>
</body>
</html>

projectFolder / app / boot。t是自举点所在的位置。

这是我能做的最好的:)

你可以在github上使用 angular-cli-ghpages

请查看链接，以了解如何使用此cli进行部署。

部署的网站通常会存储在github的某个分支中

gh-pages

使用可以克隆git分支和使用它像静态网站在您的服务器

“最佳”取决于场景。有时你只关心最小的单个包，但在大型应用程序中，你可能不得不考虑延迟加载。在某种程度上，将整个应用程序作为一个单一的bundle提供是不切实际的。

在后一种情况下，Webpack通常是最好的方法，因为它支持代码分割。

对于单个包，我会考虑Rollup，或者Closure编译器，如果你有勇气的话:-)

我已经在这里创建了我使用过的所有Angular捆绑器的示例:http://www.syntaxsuccess.com/viewarticle/angular-production-builds

代码可以在这里找到:https://github.com/thelgevold/angular-2-samples

Angular版本:4.1.x

        **Production build with

         - Angular Rc5
         - Gulp
         - typescripts 
         - systemjs**

        1)con-cat all js files  and css files include on index.html using  "gulp-concat".
          - styles.css (all css concat in this files)
          - shims.js(all js concat in this files)

        2)copy all images and fonts as well as html files  with gulp task to "/dist".

        3)Bundling -minify angular libraries and app components mentioned in systemjs.config.js file.
         Using gulp  'systemjs-builder'

            SystemBuilder = require('systemjs-builder'),
            gulp.task('system-build', ['tsc'], function () {
                var builder = new SystemBuilder();
                return builder.loadConfig('systemjs.config.js')
                    .then(function () {
                        builder.buildStatic('assets', 'dist/app/app_libs_bundle.js')
                    })
                    .then(function () {
                        del('temp')
                    })
            });


    4)Minify bundles  using 'gulp-uglify'

jsMinify = require('gulp-uglify'),

    gulp.task('minify', function () {
        var options = {
            mangle: false
        };
        var js = gulp.src('dist/app/shims.js')
            .pipe(jsMinify())
            .pipe(gulp.dest('dist/app/'));
        var js1 = gulp.src('dist/app/app_libs_bundle.js')
            .pipe(jsMinify(options))
            .pipe(gulp.dest('dist/app/'));
        var css = gulp.src('dist/css/styles.min.css');
        return merge(js,js1, css);
    });

5) In index.html for production 

    <html>
    <head>
        <title>Hello</title>

        <meta name="viewport" content="width=device-width, initial-scale=1">
        <meta charset="utf-8" />

       <link rel="stylesheet" href="app/css/styles.min.css" />   
       <script type="text/javascript" src="app/shims.js"></script>  
       <base href="/">
    </head>
     <body>
    <my-app>Loading...</my-app>
     <script type="text/javascript" src="app/app_libs_bundle.js"></script> 
    </body>

    </html>

 6) Now just copy your dist folder to '/www' in wamp server node need to copy node_modules in www.

2到14 (TypeScript)使用Angular CLI

前设置

NPM install -g @angular/cli 创建一个新的应用程序

捆绑销售的步骤

ng build(当目录为projectFolder时在命令行中运行)。 flag prod bundle for production现在是默认的(如果需要，请参阅Angular文档自定义它)。 使用Brotli压缩使用以下命令压缩资源 对于dist/*/*中的I;Do brotli $i;完成

包默认生成到projectFolder/dist(/$projectFolder for v6+)**

输出

Angular 14.0.2的大小和CLI 14.0.2的选项CSS没有Angular路由

dist/main.[hash].js Your application bundled [ size: 118 KB for new Angular CLI application empty, 36 KB compressed]. dist/polyfill-[es-version].[hash].bundle.js the polyfill dependencies (@angular, RxJS...) bundled [ size: 34 KB for new Angular CLI application empty, 11 KB compressed]. dist/index.html entry point of your application. dist/runtime.[hash].bundle.js webpack loader dist/style.[hash].bundle.css the style definitions dist/assets resources copied from the Angular CLI assets configuration

部署

可以使用ng serve——prod命令预览应用程序，该命令启动本地HTTP服务器，这样就可以使用http://localhost:4200访问带有生产文件的应用程序。这在生产中使用并不安全。

对于生产应用，必须从所选择的HTTP服务器中的dist文件夹中部署所有文件。
