Unable to bring in Angular2 bootstrap function

I am currently setting up a basic Angular 2 (beta 2) app using TypeScript. I have the code for app.ts file taken from Angular's most recent setup guide

import {Component, View, bootstrap} from 'angular2/angular2';
@Component({
    selector: 'app'
})
@View({
    template: `
        <div></div>
    `
})
class AppComponent {
    constructor() {}
}

bootstrap(AppComponent);

However, when trying to compile it, I encounter an error message:

Error TS2307: Cannot find module 'angular2/angular2'.

Alternately, if I use a different format from other sources with angular2/core instead of angular2/angular2, like this:

import {Component, View, bootstrap} from 'angular2/core';

I receive the following error:

Error TS2305: Module '"node_modules/angular2/core"' has no exported member 'bootstrap'.

What steps should I take to import all these modules successfully?

Answer №1

The bootstrap has been relocated from angular2/angular2 to angular2/platform/browser. Therefore, you must now import it as:

import {Component, View} from 'angular2/core';
import {bootstrap} from 'angular2/platform/browser';

Answer №2

Updates in Angular2 alpha-53 have altered the list of imports, moving away from the traditional angular2/angular2

With Angular2 alpha-53, it's now possible to import bootstrap from angular2/platform/browser.

For those in need, here is a comprehensive list of all the imports:

import{Component,View,Directive,Input,Output,Inject,Injectable,provide,ElementRef} from 'angular2/core'; 

import {bootstrap} from 'angular2/platform/browser';

import{CORE_DIRECTIVES,FORM_DIRECTIVES,NgClass,NgIfNgForm,Control,ControlGroup, FormBuilder, Validators} from 'angular2/common';

import{RouteConfig,ROUTER_DIRECTIVES,ROUTER_PROVIDERS,Router,LocationStrategy, HashLocationStrategy} from 'angular2/router';

import {Http, HTTP_PROVIDERS, RequestOptions, Headers, Request, RequestMethod} from 'angular2/http'

Note: The import list has undergone significant changes, as detailed in the official Angular changelog for version 2.0 alpha 53 dated December 13, 2015.
