404 Not Found @angular/platform-browser.js


I try setup ASP.NET MVC 5 (not Core) + Angular 2.0.0 + JSPM + SystemJS + TS Loader.

When I run app I get error:

Failed to load resource: the server responded with a status of 404 (Not Found)
http://localhost:59711/@angular/platform-browser.js

Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:59711/@angular/platform-browser.js(…)

@angular packages are in folder jspm_packeges/npm.

Now I really don’t know what is root of problem some breaking change in Angular or something in SystemJS.

Here are my configuration files:

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    /* target of the compilation (es5) */
    "module": "system",
    /* System.register([dependencies], function) (in JS)*/
    "moduleResolution": "node",
    /* how module gets resolved (needed for Angular 2)*/
    "emitDecoratorMetadata": true,
    /* needed for decorators */
    "experimentalDecorators": true,
    /* needed for decorators (@Injectable) */
    "noImplicitAny": false
    /* any has to be written explicity*/
  },
  "exclude": [
    /* since compiling these packages could take ages, we want to ignore them*/
    "jspm_packages",
    "node_modules"
  ],
  "compileOnSave": false
  /* on default the compiler will create js files */
}

config.js (jspm, configuration files is simplified)

System.config({
  baseURL: "/",
  defaultJSExtensions: true,
  transpiler: "babel",
  babelOptions: {
    "optional": [
      "runtime",
      "optimisation.modules.system"
    ]
  },
  typescriptOptions: {
    "tsconfig": true
  },
  paths: {
    "github:*": "jspm_packages/github/*",
    "npm:*": "jspm_packages/npm/*"
  },

  packages: {
    "app": {
      "main": "bootstrap",
      "format": "system",
      "defaultExtensions": "ts",
      "meta": {
        "*.ts": {
          "loader": "ts"
        }
      }
    }
  },

  map: {
    "@angular/common": "npm:@angular/[email protected]",
    "@angular/compiler": "npm:@angular/[email protected]",
    "@angular/core": "npm:@angular/[email protected]",
    "@angular/http": "npm:@angular/[email protected]",
    "@angular/platform-browser-dynamic": "npm:@angular/[email protected]",

    "github:frankwallis/[email protected]": {
      "typescript": "npm:[email protected]"

      //...
  }
});

index.html

<script>
    System.config
    ({
        transpiler: "ts",
        packages:
        {
            "app": {
                "defaultExtension": "ts",
            }
        }
    });

System.import('app/bootstrap').catch(console.log.bind(console));
</script>

Visual Studio complains for all angular imports.

bootstrap.js

import {bootstrap} from "@angular/platform-browser"
import {provide} from "@angular/core"

Solution

  • Seems like: '@angular/platform-browser': 'npm:@angular/[email protected] package is missing.

    map: {
        "@angular/common": "npm:@angular/[email protected]",
        "@angular/compiler": "npm:@angular/[email protected]",
         ...
         ...
        '@angular/platform-browser': "npm:@angular/[email protected]"
         ...
         ...
    }
    

    Note: Also add it to package.json if already not there,

    "dependencies": {
        "@angular/common": "2.0.0",
        "@angular/compiler": "2.0.0",
         ...
         ...
        "@angular/platform-browser": "2.0.0",
         ...
    }
