今天被問到說要怎麼升 angularjs 到 angular … 老實說沒啥心情想管 , wtf 硬著頭皮寫這篇
目前只研究到讓他活在 cshtml 裡面 , 不過這種方式感覺不是很優 , 整個超亂 XD
可以參考這篇

先開個 asp.net core mvc 專案 , 接著在專案底下開個 angular 專案

1
ng new ClientApp

找到 angular.json 調整設定 outputPath 為 ../Scripts/ClientApp

5
"architect": {
  "build": {
    "builder": "@angular-devkit/build-angular:browser",
    "options": {
      "outputPath": "../Scripts/ClientApp",

設定完後編譯他就會在專案底下的 Script\ClientApp 產生出 angular 網站的東西

1
ng build --watch

安裝 WebOptimizer 並在 Program 底下設定這樣

builder.Services.AddWebOptimizer(pipeline =>
{
    pipeline.AddJavaScriptBundle("/js/clientapp",
        "Scripts/ClientApp/runtime.*",
        "Scripts/ClientApp/polyfills.*",
        "Scripts/ClientApp/main.*"
        )
    .UseContentRoot();

    pipeline.AddCssBundle("/css/clientapp",
        "Scripts/ClientApp/styles.*")
    .UseContentRoot();

});

記得要設定 UseWebOptimizer 在 UseStaticFiles 才會生效

1
2
app.UseWebOptimizer();
app.UseStaticFiles();

設定 MapFallbackToController 路徑 , 這樣 angular 的 route 才能動

1

3

5
6
app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}"
    );

app.MapFallbackToController("Index", "Home");

最後設定 _Layout

 *@
    <script src="~/js/clientapp"></script>
    @await RenderSectionAsync("Scripts", required: false)
</body>
</html>

在 angular 專案上則是讓 app.component.html 只留下 <router-outlet></router-outlet> 即可

app-routing.module.ts 則需要設定 routing

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HelloWorldComponent } from './HelloWorld/HelloWorld.component';

const routes: Routes = [
  {
    path: 'HelloWorld',
    component: HelloWorldComponent,
  },
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule],
})
export class AppRoutingModule {}

然後新開的頁面也是需要一個 Index.cshtml 當作入口

public class HelloWorldController : Controller {
	public IActionResult Index(){
		return View();
	}
}

接著 cshtml 大概會長下面這樣

@{
    ViewBag.Title = "HelloWorld";
    Layout = "_LayoutAngular";
}

@Html.Partial("_PartialBreadCrumb")


<app-root></app-root>
<app-hello-world></app-hello-world>
