AngularJS Question

Using angular1 component (requirejs module) inside angular2 component

I have an ng1 component in javascript written as requirejs module.
I need to use this component inside my ng2 component (until my old ng1 app is fully ported to ng2).
Here is the plnkr : https://plnkr.co/edit/IYuoZZE4sPGr97pxB04l?p=preview
Here is my bootstrap logic:

import {App} from './app';
import {upgradeAdapter} from './adapter';

var appComponent = upgradeAdapter.downgradeNg2Component(App);

requirejs( ['ng1App'],
function(ng1App) {
angular.module('ng1App').directive('myApp',appComponent);
// following line throws error
upgradeAdapter.bootstrap(document.body, ['ng1App']);
} );


it gives me following error

angular2-polyfills.js:286 Uncaught Error: AngularJS v1.x is not loaded!


Appreciate any pointers.

The other question i have is how do i import the requirejs modules for individual ng1 components in my ng2 component :

import {Component} from '@angular/core'
import {upgradeAdapter} from './adapter';

// How do i dynamically load the ng1-comp rquirejs module here?

@Component({
selector: 'my-app',
providers: [],
template: `
<div>
<h2>Hello {{name}}</h2>
</div>
<ng1-comp></ng1-comp>
`,
directives: [upgradeAdapter.upgradeNg1Component('ng1Comp')]
})
export class App {
constructor() {
this.name = 'Angular2 (Release Candidate!)'
}
}

Answer

Finally figured it out.. The requirejs config needs to be converted to systemjs or other module loader config. Converting to system js is easy..

// map systemJS apis to corresponding apis in requirejs
window.require = System.amdRequire;
window.requirejs = System.amdRequire;
window.define = System.define;
System.config(function getNG1Config() {
  return {
    defaultJSExtensions: true,
    baseUrl: '/',
    waitSeconds: 0,
    paths: {
      'angular-ui-router': 'https://npmcdn.com/angular-ui-router@0.3.0/release/', //needs to be defined before 'angular'
