SystemJS捆绑应用程序对Angular 5的依赖性

我有角5应用程序。我想尽可能缩小和捆绑我的应用程序。

这是SystemJS的配置:

(function (global) {
    System.config({
        paths: {
            'npm:': "node_modules/"
        },
        map: {

GulpFiel.JS:

var gulp = require('gulp');
var tsc = require('gulp-typescript');
var systemjsBuilder = require('systemjs-builder');
var angularEmbed = require('gulp-angular-embed');
var del = require('del');

var tsProject = tsc.createProject('tsconfig.json');
var builder = new systemjsBuilder('', 'systemjs.config.js');

gulp.task('bundle-config', function () {
    return gulp.src('systemjs.config.js')
        .pipe(gulp.dest('dist/configs'));
});

gulp.task('embed-template', ['bundle-config'], function () {
    return gulp.src('app/**/*.ts')
        .pipe(angularEmbed())
        .pipe(gulp.dest('dist2'));
});

gulp.task('tsc', ['embed-template'], function () {
    return gulp.src('dist2/app/**/*.ts')
        .pipe(tsProject())
        .js.pipe(gulp.dest('dist'));
});

gulp.task('clean', ['tsc'], function () {
    return del(['dist2/**']);
});

gulp.task('bundle-app', ['clean'], function () {
    return builder
        .bundle('[dist/**/*]', 'production/app.bundle.min.js', {
                minify: true,
                mangle: true
            })
        .then(function () {
            console.log('Build complete');
        })
        .catch(function (err) {
            console.log('Build error');
            console.log(err);
        });
});

gulp.task('bundle-dependencies', ['clean'], function () {
    return builder
        .bundle('dist/**/* - [dist/**/*.js]', 'production/dependencies.bundle.min.js', {
                minify: true,
                mangle: true
            })
        .then(function () {
            console.log('Build complete');
        })
        .catch(function (err) {
            console.log('Build error');
            console.log(err);
        });
});

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

和index.html包含以下内容:

<!DOCTYPE html>
<html>
<head>...</head>
<body>
  <my-app></my-app>

  <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="production/dependencies.bundle.min.js"></script>
  <script src="production/app.bundle.min.js"></script>
  <script>
      System.import('dist/configs/systemjs.config.js').then(function() {
          System.import('app').catch(function(err){ console.error(err); });
      });
  </script>
</body>
</html>

结果我在“dist”文件夹中编译了应用程序(JS文件中包含HTML)。我还有“生产”文件夹 app.bundle.min.js “我的所有应用程序文件和” dependencies.bundle.min.js “在这里,我所有的依赖,比如Angular、Kendo、RXJS框架。 当我启动我的应用程序时,它会分别加载这两个小型文件和所有依赖项,例如:

/node_modules/rxjs/add/operator/mergeMap.js
/node_modules/@progress/kendo-angular-grid/dist/npm/data/data.iterators.js
/node_modules/@angular/animations/bundles/animations.umd.min.js

但他们都在 依赖项.bundle.min.js “。

我如何解决?
