【问题描述】:
我正在使用 dotnet 核心在不同的子目录中提供独立的 Angular 应用程序。看到这个东西在起作用真是太棒了,但我遇到了一些我不明白的东西。
我的应用程序在这里:
wwwroot/
pap/
admin/
boot.ts
admin.component.ts
此应用的 MVC 路由是 /pap/admin/。在这种情况下,我希望 Angular2 路由有两种工作方式。首先是构建我所有的 Angular 路由以匹配 MVC 路由。这行得通,但感觉很便宜。第二种方法是这样设置基本标签:
<base href="/pap/admin/">
这两种方式都允许我独立使用服务器端和客户端路由,而无需在每条路由之前添加 /panel/admin/。例如,
@RouteConfig([
{ path: '/menu', name: 'Menu', component: MenuComponent, useAsDefault: true },
{ path: '/panels/:id', name: 'Panel', component: PanelComponent }
])
我的问题在于 SystemJS。我已经尝试,阅读,搜索,但我仍然不知道发生了什么。在快速入门中,Angular 库包含在脚本标签中。如果我理解正确,则不需要告诉应用程序从哪里加载 Angular 和 Rxjs,因为它们已经包含在文档中。
这些库位于 node_modules 中,就像它们位于 wwwroot/ 中一样提供服务。有了 ,我的应用程序自然会开始寻找 /pap/admin/angular2/ 中的文件,而不是它们所在的位置。如果我使用这个配置,
System.config({
baseURL: '/',
defaultJSExtensions: true,
packages: {
format: 'register',
'pap/admin': { defaultExtension: 'js' }
}
});
System.import('/pap/admin/admin.boot.js')
.then(null, console.error.bind(console));
然后整个事情都爆炸了,寻找我曾经进口过的所有东西,从
import {bootstrap} from 'angular2/platform/browser';
它在根目录(wwwroot 或 http://localhost:5000/angular2/platform/browser.js)而不是 /node_modules/angular2/ 中寻找它。这对我来说很有意义,虽然我不完全理解为什么它不使用我在脚本标签中加载的库。
如果我使用
System.config({
baseURL: '/node_modules/',
defaultJSExtensions: true,
packages: {
format: 'register',
'pap/admin': { defaultExtension: 'js' }
},
});
System.import('/pap/admin/admin.boot.js')
.then(null, console.error.bind(console));
应用程序栩栩如生。即使我从脚本标签中删除库,它也会这样做。当然,SystemJS 现在知道如果我从 'angular2/core' 导入某些东西,它可以在 /node_modules/ 中查找它。这里的缺点是,就初始而言,性能明显较慢。检查 dotnet core 的输出,我可以看到它正在加载这些库中的每个文件。哎呀。
我想如果我使用 baseURL: '/' 并将 Angular 位映射到它们所在的位置,一切都会好起来的,
map: { angular2: '/node_modules/angular2/' }
但结果是一样的;加载完最后一块。
还有一件事……SystemJS 说他们很快就会摆脱 defaultJSExtensions,但是一旦我添加并开始讨论 System.config 部分,没有它就无法工作。
如果任何有 SystemJS 经验或在新的 dotnet 核心内容之上构建的人提供一些指导,我将不胜感激。

我尝试开始使用 jspm,但正如我在下面评论的那样,要么我在做一些疯狂的事情,要么就是这样。这是我只运行 jspm install angular2 后的 config.js:

在浏览 jspm 在我的节点库中映射到的内容列表时,我注意到了这一点:
"npm:angular2@2.0.0-beta.9": {
"crypto": "github:jspm/nodelibs-crypto@0.1.0",
"es6-promise": "npm:es6-promise@3.1.2",
"es6-shim": "npm:es6-shim@0.33.13",
"process": "github:jspm/nodelibs-process@0.1.2",
"reflect-metadata": "npm:reflect-metadata@0.1.2",
"rxjs": "npm:rxjs@5.0.0-beta.2",
"zone.js": "npm:zone.js@0.5.15"
},
在其他地方,我看到有人分别安装这些库中的每一个,但现在安装 angular2 看起来像是在自行引入通常的依赖项。

您的问题已从如何从另一个目录提供 Angular2 变为如何使用 JSPM 安装 Angular2。我的观点是,在 StackOverflow 上,当有人提供有用的答案或完全回答了我们的问题时,我们会通过投票或将答案标记为正确来奖励他们。然后我们根据所学提出一个新问题。
