angularjs - Component does not displays in UI page -


i started learning angular2 , tried "hello world" program. have created .ts file this:

appcomponent.ts

import {   ngmodule,   component } '@angular/core'; import {browsermodule} '@angular/platform-browser'; import {platfrombrowserdynamic} '@angular/platfrom-browser-dynamic';  @component({   selector:'hello-world',   template:`   <div>     hello world   </div>` }) class helloworld { } @ngmodule({   declaration: [helloworld],   imports:[browsermodule],   bootstrap:[helloworld], }) class helloworldappmoduel{ }  platformbrowserdynamic().bootstrapmodule(helloworldappmoduel); 

but when deployed , ran code in tomcat, didn't show anything, should show "hello world". not able why nothing appeared in ui.

/* importing component decorator function anularjs library module */  system.register(['@angular/core', '@angular/platform-browser'], function(exports_1, context_1) {      "use strict";      var __modulename = context_1 && context_1.id;      var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {          var c = arguments.length, r = c < 3 ? target : desc === null ? desc = object.getownpropertydescriptor(target, key) : desc, d;          if (typeof reflect === "object" && typeof reflect.decorate === "function") r = reflect.decorate(decorators, target, key, desc);          else (var = decorators.length - 1; >= 0; i--) if (d = decorators[i]) r = (c < 3 ? d(r) : c > 3 ? d(target, key, r) : d(target, key)) || r;          return c > 3 && r && object.defineproperty(target, key, r), r;      };      var __metadata = (this && this.__metadata) || function (k, v) {          if (typeof reflect === "object" && typeof reflect.metadata === "function") return reflect.metadata(k, v);      };      var core_1, platform_browser_1;      var helloworld, helloworldappmoduel;      return {          setters:[              function (core_1_1) {                  core_1 = core_1_1;              },              function (platform_browser_1_1) {                  platform_browser_1 = platform_browser_1_1;              }],          execute: function() {              helloworld = (function () {                  function helloworld() {                  }                  helloworld = __decorate([                      core_1.component({                          selector: 'hello-world',                          template: "\n<div>\nhello world\n</div>\n"                      }),                       __metadata('design:paramtypes', [])                  ], helloworld);                  return helloworld;              }());              helloworldappmoduel = (function () {                  function helloworldappmoduel() {                  }                  helloworldappmoduel = __decorate([                      core_1.ngmodule({                          declaration: [helloworld],                          imports: [platform_browser_1.browsermodule],                          bootstrap: [helloworld],                      }),                       __metadata('design:paramtypes', [])                  ], helloworldappmoduel);                  return helloworldappmoduel;              }());              platformbrowserdynamic().bootstrapmodule(helloworldappmoduel);          }      }  });  //# sourcemappingurl=appcomponent.js.map

main.ts file

import {bootstrap} 'angular2/platform/browser'  import {appcomponent} './appcomponent'  bootstrap(appcomponent); 

pfb snippet. what's going on?

edit 2: here's systemjs.config.js file:

/**  * system configuration angular samples  * adjust necessary application needs.  */ (function (global) {   system.config({     paths: {       // paths serve alias       'npm:': 'node_modules/'     },     // map tells system loader things     map: {       // our app within app folder       app: 'app',       // angular bundles       '@angular/core': 'npm:@angular/core/bundles/core.umd.js',       '@angular/common': 'npm:@angular/common/bundles/common.umd.js',       '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',       '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',       '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',       '@angular/http': 'npm:@angular/http/bundles/http.umd.js',       '@angular/router': 'npm:@angular/router/bundles/router.umd.js',       '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',       '@angular/upgrade': 'npm:@angular/upgrade/bundles/upgrade.umd.js',       // other libraries       'rxjs':                      'npm:rxjs',       'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'     },     // packages tells system loader how load when no filename and/or no extension     packages: {       app: {         main: './main.js',         defaultextension: 'js'       },       rxjs: {         defaultextension: 'js'       }     }   }); })(this); 

edit 3: after editing package.json file this

{   "name": "angularjs2-app",   "version": "1.0.0",   "scripts": {     "start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",     "tsc": "tsc",     "tsc:w": "tsc -w",     "lite": "lite-server",     "typings": "typings",     "postinstall": "typings install"   },   "license": "isc",   "dependencies": {     "angular2": "2.0.0-beta.14",      "@angular/common": "~2.1.1",     "@angular/compiler": "~2.1.1",     "@angular/core": "~2.1.1",     "@angular/forms": "~2.1.1",     "@angular/http": "~2.1.1",     "@angular/platform-browser": "~2.1.1",     "@angular/platform-browser-dynamic": "~2.1.1",     "@angular/router": "~3.1.1",     "@angular/upgrade": "~2.1.1",      "angular-in-memory-web-api": "~0.1.5",     "core-js": "^2.4.1",     "systemjs": "0.19.25",     "es6-shim": "^0.35.0",      "es6-promise": "^3.0.2",     "reflect-metadata": "0.1.2",     "rxjs": "5.0.0-beta.2",     "zone.js": "0.6.6"    },   "devdependencies": {     "concurrently": "^2.0.0",     "lite-server": "^2.2.0",     "typescript": "^1.8.9",     "typings":"^0.7.12"   } } 

most of error has gone still 1 error persisted

zone.js:306 error: referenceerror: platformbrowserdynamic not defined         @ execute (http://localhost:3000/angularassign/appcomponent.js:50:13)         @ zonedelegate.invoke (http://localhost:3000/node_modules/zone.js/dist/zone.js:306:29)         @ zone.run (http://localhost:3000/node_modules/zone.js/dist/zone.js:201:44)     error loading http://localhost:3000/angularassign/appcomponent.js 

please let me still remaining add?

here working example , few things whatch when creating new components,

  1. anytime create component must add

app.module.ts example

import { ngmodule }                         '@angular/core'; import { browsermodule }                    '@angular/platform-browser';     import { hellocomponent }                  './hello.component';     @ngmodule({         declarations: [ hellocomponent ],         imports: [             hellocomponent,         ],         bootstrap: [appcomponent]     })     export class appmodule {      } 

then create route,

app.routing.ts

import { routes, routermodule }     "@angular/router"; import { hellocomponent }                  './hello.component';  const app_routes: routes = [     { path: '', component: hellocomponent } ]; export const routing = routermodule.forroot(app_routes); 

then have 2 component files,

once

hello.component.ts

   import { component, oninit } '@angular/core';      @component({       templateurl: './hello.component.html',     })      export class hellocomponent {        constructor() { }      } 

and can see instead ot using template , injecting html specify template. load html file specify. last file is,

hello.component.html 

make sure have , run. every time want add new component or view follow these steps.
