I started developing a hybrid application. So I have done th folllowing steps:
add Angular 8 dependencies
add polyfills.ts
remove ng-app attribute 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 ?

We had created a component named contact using angularjs#1.6 and angular-ui-router#1.0.0-rc.1.The problem lies on click of a button,nothing is displayed in the home page.It would be great if someone could help us to figure out the error.

angular.module('app',[]);

angular
.module('contactApp', ['ui-router']);

angular
.module('contactApp')
.config(['$stateProvider',function ($stateProvider) {
$stateProvider.state('contact', {
url: '/contact',
component: 'contact'
})
}])
.component('contact',{
template: `<h1>Contact</h1>`
})
You app module, where component is registered, is contactApp. You need to change html to that app module:
<div ng-app="contactApp">
EDIT
If we assume that app is the main app module and there are other modules declared, then all the other have to be registered under that main app like this:
angular.module('app', ['contactApp']);
and then in html you use app, as you already do:
<div ng-app="app">
*You can also have multiple apps in the same html but it is not the recommented way
I was trying to merge AngularJS and VueJS projects together since we need to have a requirement of calling the flow designed in VueJS from inside an AngularJS app. For merging AngularJS and VueJS projects together, I included the dependencies in package.json file of Angular and Vue together and few other files too.
Now since both Vue and Angular have an index.html file created in the project root directory, I made the Angular one as my index.html file and renamed VueJS index file as index23.html. Then from the link from where I need to call VueJS flow, I provided the path in the router of AngularJS config file as shown:
'use strict';
app.config(function ($routeProvider) {
$routeProvider
.when("/errorinput", {
templateUrl: "src/index23.html"
});
});
app.controller('ErrorInputCtrl', ['$scope', '$http', function ($scope, $http) {
// Implement me!
}]);
But on doing so, my VueJS page doesn't comes up but rather it comes up in background I think as current page gets surrounded with a white background on clicking that link. I am really not sure if I need to code something inside the app.controller method of above file since this is a Vue component which I am talking about.
Is there any way we can make this work? Please let me know if I need to provide additional details. Contents of index.html file from where this call is made are below:

This is the Angular page and link(Manage Error Descriptions) from where I need to call VueJS app:

app.config(function ($routeProvider) {

Vue and Angular can co-exist on a page just fine.
Because you're using Angular to render Vue's HTML, you'll need to make sure your Vue initialization fires after the new HTML is rendered. You could accomplish this a couple of ways:
Paste your Vue script where it says // Implement me in your code above
Use a hook in your Angular router to load your Vue-specific .js file after the route has loaded
First option is probably more performant, while second option probably keeps your dev setup cleaner.
I have a node.js application running Express and express handlebars as the templating framework. I have recently started learning Angular and integrating it in my node.js app.
The only issue is, the markup for express-handlebars and angular is same. Both framework use {{}}. I did some research and found this Stackoverflow question: Using Express Handlebars and Angular JS
The accepted answer suggests changing the markup symbols using the interpolateProvider. I implemented this and it does not work for me (I have commented under that answer).
My code looks like this:
main.handlebars
<!DOCTYPE html>
<html ng-app="myapp">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>GETTING STARTED WITH Angular</title>
<meta name="description" content="An interactive getting started guide for Brackets.">
<link rel="stylesheet" href="/css/style.css"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular-route.min.js"></script>
<script>
var app = angular.module("myApp", []);
app.config(function($interpolateProvider) {
$interpolateProvider.startSymbol('//');
$interpolateProvider.endSymbol('//');
});
app.controller('DemoController', function() {
this.label = "This binding is brought you by // interpolation symbols.";
});
</script>
</head>
<body>
{{{body}}}
<input ng-model="name">
<h3>Hi, //name// how are you doing</h3>
<div ng-controller="DemoController as demo">
//demo.label//
</div>
</body>
</html>
The above code is from the main.handlebars layout file. I even tried to put that code in the actual view but it did not work. What am I missing?
Thanks.
This issue is occurring because of an incorrect app name reference or a simple typo. Change ng-app="myapp" to ng-app="myApp".

This way of coding is not supported by angular 1.4.7 however it is supported by angular <1.3.0.
I recommend you to follow this style of coding https://docs.angularjs.org/api/ng/directive/ngController
ngApp: ng-app description
<body ng-app>
Or
<html ng-app>
Use this directive to auto-bootstrap an AngularJS application. The ngApp directive designates the root element of the application and is typically placed near the root element of the page - e.g. on the or tags.
This automatically bootstraps your angular application and then all is good to go. But I like to bootstrap it manually on DOM ready event.
It's upto you. If you are building a sample app and trying to learn then ng-app is fine for you, but in case of large application you should need to make Modules.
I've been sitting with this problem for a few hours and found a few answers, none of which have worked for me so far (AngularJs ReferenceError: angular is not defined). For some reason I can't seem to get my app to use Angular.JS. After adding the required js-files, my main file looks like this:
<!DOCTYPE html>
<html ng-app="AppName">
<head>
<title></title>
<link rel="stylesheet" href="/stylesheets/main.css">
</head>
<body>
<!-- Wrapper-->
<div id="wrapper">
<div id="page-content-wrapper">
<div class="page-content inset" ng-view>
</div>
</div>
</div>
<!-- /WRAPPER-->
<!-- ANGULAR CUSTOM -->

<script src="javascripts/controllers/MainCtrl.js"></script>
<script src="javascripts/controllers/SettingsCtrl.js"></script>
<script src="javascripts/services/SettingsService.js"></script>
</body>
</html>
When I run the app it never seems to finish loading (see the image: http://imgur.com/FIAH4tH) and then crashes. In Firefox, I get the following error: http://imgur.com/UT3g7wY
Does anyone know how I can solve this problem?
--EDIT--
I've updated the position of the scripts in the app.
My AngularApp.js file looks like this:
angular.module('AppName', ['ngRoute', 'appRoutes', 'MainCtrl', 'SettingsCtrl', 'SettingsService']);
If your module AppName is defined in AngularApp.js, that needs to come before MainCtrl js.
Are your .js files separate angular modules? If so, they should not be listed as modules in your angular.module dependencies.
angular.module('AppName', ['ngRoute']);
Definitely include any of the libs/ files before your own custom code.
So put <script src="libs/angular/angular.js"></script> and <script src="libs/angular-route/angular-route.min.js"></script> before your other javascripts files and you should find the problem fixed.
I was having the same problem. Declaring the angular script tag in html's <head> tag worked for me. Therefore:
<!doctype html>
<html lang="en" ng-app>
<head>
<meta charset="utf-8">
<title>AngularJS tryout</title>
<script src="../../node_modules/angular/angular.js"></script>
</head>
<body>
<h1>AngularJS tryout</h1>
<p>Nothing here so {{ 'far' + '!' }}</p>
</body>
</html>
