新的 Angular 2.0.0-rc.5 项目需要最少的包？

Question

我正在做涉及 Angular 2 的第二个项目。在第一个 Angular 2 项目热身后，从 Angular 1.5 跳转时，我真的对如何 trim 下包感兴趣。我想知道我可以在不丢失核心功能的情况下从 package.json 文件中删除什么。每个包有什么作用，我应该保留什么？

目前我的理解是这样的：

{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    "start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
    "lite": "lite-server", // I use Webstorm, Visual Studio or Xampp
    "postinstall": "typings install", // ???
    "tsc": "tsc",
    "tsc:w": "tsc -w", // Maybe I will keep
    "typings": "typings"
  },
  "license": "ISC",
  "dependencies": {
    "@angular/common": "2.0.0-rc.5", // ng-if, ng-for seem to reside in here
    "@angular/compiler": "2.0.0-rc.5", // renders the templates
    "@angular/core": "2.0.0-rc.5", // :)
    "@angular/forms": "0.3.0", // I could manage without, I use custom css
    "@angular/http": "2.0.0-rc.5", // Need it
    "@angular/platform-browser": "2.0.0-rc.5", // ???
    "@angular/platform-browser-dynamic": "2.0.0-rc.5", // ???
    "@angular/router": "3.0.0-rc.1", // Need it
    "@angular/router-deprecated": "2.0.0-rc.2", // Nope
    "@angular/upgrade": "2.0.0-rc.5", // Nope
    "systemjs": "0.19.27", // importing modules
    "core-js": "^2.4.0", // Some polyfills, Does Chrome 52.0 needs it?
    "reflect-metadata": "^0.1.3", // Decorators ??
    "rxjs": "5.0.0-beta.6", // depdency for EventEmitter 
    "zone.js": "^0.6.12", // data bindings don't work wihtout
    "angular2-in-memory-web-api": "0.0.15", // ???
    "bootstrap": "^3.3.6" // No need, I do all my css hand forged to perfection.
  },
  "devDependencies": {
    "concurrently": "^2.0.0", // Nope
    "lite-server": "^2.2.0", // Nope
    "typescript": "^1.8.10", // Nope ? I learned that Webstorm can do this job
    "typings":"^1.0.4" // Nope ?
  }
}

你找错人了。

如 the official blog post accompanying the RC5 release

中所述

Roughly 60% of Angular’s code size is the compiler [...] so enabling AoT compilation means you don’t have to ship that code to your users

如果您关心的是减少网络传输的字节数，我建议您学习如何通过将 AoT 编译合并到您的构建过程中来利用它（对于您的问题，这将允许您删除 compiler 和 platform-browser-dynamic 生产包中的模块）

还值得注意的是，在准备最终发布时削减这些模块的大小 is one of the major focuses for RC6，因此恕我直言，使用 RC5 执行您正在执行的操作主要是浪费时间。
