How to prevent Angular2 core making dozens of HTTP requests on page load?

Question

So I\'m developing an Angular2 application, and just by bootstrapping Angular2, I\'m sent over 250 requests for nearly every js file present in the @angular/core

Answer 1

There is new systemjs config in official quickstart https://angular.io/guide/quickstart

Here is the copy

// Add package entries for angular packages
  ngPackageNames.forEach(function(pkgName) {
    packages['@angular/'+pkgName] = { main: pkgName + '.umd.js', defaultExtension: 'js' };
  });

So we can use their UMD bundle, and I tried it, from ~400 requests to about ~60 requests.
