Angular 8 hybrid app not recognizes AngularJS components
Question
I started developing a hybrid application. So I have done th folllowing steps:
- add Angular 8 dependencies
- add
polyfills.ts - remove
ng-appattribute from my root index.html - do a manual bootstrap of AngularJs app
How looks my Angular init module:
@NgModule({
imports: [
BrowserModule,
UpgradeModule
]
})
export class HubAngularModule {
ngDoBootstrap() {
}
}
platformBrowserDynamic().bootstrapModule(HubAngularModule)
.then(platformRef => {
console.log("Bootstrapping in Hybrid mode with Angular & AngularJS");
const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
upgrade.bootstrap(document.body, ['myAngularJsModule']);
});
How looks my index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<script src="dist/index.bundle.js"></script> <!--Webpack bundle-->
<link rel="stylesheet" href="dist/styles.css"/>
</head>
<body>
<div layout="column" layout-align="" ng-cloak>
<main-header></main-header> <!--AngularJS header component-->
<console-menu></console-menu> <!--AngularJS menu component-->
<md-content ui-view="main"></md-content> <!--AngularJS root ui-view-->
</div>
</body>
</html>
main-header, console-menu - are AngularJS components. Of course that configuration works well when ng-app is presented.
What I expect. Hybrid app starts just like old AngularJS app and I'm able to see login page, start page etc.
What I actually got. AngularJS app is actually bootstrapping. I can see method app.module().run(...) executes. But no component loads so I see only a blank page.

After a several hours of experiments I have found a soultion. I decided to check whether the manual bootstrap of the AngularJS will work:
angular.element(document)
.ready(() => {
angular.bootstrap(document.body, ['myAngularJsModule']);
});
And it had failed. Even if no Angular 8 present. So the reason it fails to start is a location of <script> tags with my webpack bundles. It located in <head> but should be located in <body> after all the app markup.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
</head>
<body>
<div layout="column" layout-align="" ng-cloak>
<main-header></main-header> <!--AngularJS header component-->
<console-menu></console-menu> <!--AngularJS menu component-->
<md-content ui-view="main"></md-content> <!--AngularJS root ui-view-->
</div>
<script src="dist/index.bundle.js"></script> <!--Webpack bundle-->
<link rel="stylesheet" href="dist/styles.css"/>
</body>
</html>
It is so dumb, but exactly that dumb thing like this make the biggest headache sometimes. And what disappointed me me the most not a single migration tutorial tells nothing about that detail!

Have you upgraded your angularJS components to make them work in Angular?
