Attempted to load Angular multiple times

Question

Attempted to load Angular multiple times

I recently developed an app using the Yeoman scaffolded app (specifically, the Angular Fullstack generator).

While grunt serve works perfectly fine, I encountered a problem when running grunt build which results in the distribution locking up memory. This issue is likely caused by circular references within Angular.

To address this, I decided to upgrade Angular to version 1.2.15, but now I'm facing a new error message:

WARNING: Tried to Load Angular More Than Once

Prior to the upgrade, I was getting the following error:

Error: 10 $digest() iterations reached. Aborting!

The debugging process has been challenging as the error only surfaces after the build and minification process. Despite ensuring that all my modules are in Angular's array format to prevent DI issues during minification, the problem persists.

No single script seems to be causing this issue - the only workaround I've found is to not initialize with my app.js file. For reference, here is the content of my app.js file:

'use strict';

angular.module('myApp', [
  'ngCookies',
  'ngResource',
  'ngSanitize',
  'ngRoute',
  'ngTagsInput',
  'ui.bootstrap',
  'google-maps',
  'firebase'
]);

angular.module('myApp').config(['$routeProvider', function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/listing.html',
        controller: 'ListingCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  }]).constant('FIREBASE_URL', 'something');

javascript angularjs gruntjs

Answer 1

Answer №1

There are various potential issues at play here: essentially, the root cause seems to lie with routeProvider being unable to locate a file and continuously loading the default instead.

In my experience, the problem was not due to minification but rather the concatenation of JavaScript files that led to these issues.

angular.module('myApp').config(['$routeProvider', function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/listing.html',
        controller: 'ListingCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  }]).constant('FIREBASE_URL', 'something');

If the application cannot find a specified file (e.g., using otherwise), it will fallback to the root, which triggers the loading of the templateUrl. However, if the templateUrl is incorrect, it can result in a recursive loop where index.html constantly reloads angular (and other components).

In my case, the issue stemmed from grunt-concat modifying the templateUrl after building the project.

The issue may arise when $templateCacheProvider attempts to locate a template in the templateCache or within your project directory that is not present

For instance:

templateUrl: 'views/incorrectPathToTemplate'

Corrected version should be:

templateUrl: 'views/home.html'

This warning has nothing to do with app.js. Instead, it occurs when the Angular JS library is included multiple times.

I was able to replicate this issue in this JSBin. Take note of the two script tags pointing to different versions:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.14/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>

You can find relevant Angular code on GitHub.

I encountered a similar issue where I found myself stuck in an endless loop, with the page continuously reloading itself. Upon investigating further, I discovered that the problem stemmed from Angular being unable to load a template specified by a certain id because it was not present in the file.

It's important to double-check the URLs used in Angular applications. If there is an error in the URL, Angular may end up endlessly searching for it, resulting in a never-ending loop!

I hope this information proves helpful!

Encountering a similar problem, I discovered that it stemmed from a clash between JQuery and Angular. Since Angular didn't require the full JQuery library, simply including JQLite sufficed for most scenarios. To resolve the issue, I prioritized loading Angular before JQuery on my webpage, resulting in the elimination of the error.

Encountered a problem today and wanted to share how I solved it. I had an index.html page that looked like this:

<body ng-app="myApp" ng-controller="mainController"
   <div ng-view></div>
</body>

In my app.js file, I had the following code:

$routeProvider.when('/', {
    controller : 'mainController',
    templateUrl : 'index.html',
    title : 'Home'
  }).when('/other', {
    controller : 'otherController',
    templateUrl : 'views/other.html',
    title : 'other'
  }).otherwise({
    redirectTo : '/'
  });

The issue arose when I visited the page (base_url/) and saw that index.html was loading within itself multiple times, causing an endless loop of loading angular libraries.

To fix this, all I had to do was remove index.html from the $routeProvider, as shown below:

$routeProvider.when('/other', {
    controller : 'otherController',
    templateUrl : 'views/other.html',
    title : 'other'
  }).otherwise({
    redirectTo : '/'
  });

My experience was quite similar - what I found was that the root of the problem lay in missing semicolons within the controller. It seemed that when the app was minified, this led to the code not executing as intended (presumably resulting in state mutations, triggering view rendering, and causing the controller to repeatedly run the code in a recursive loop).

Answer №11

Remember, capitalization plays a key role! When working on my directive, I initially set it as:

templateUrl: 'Views/mytemplate'

This resulted in a warning about duplication. However, after changing it to:

templateUrl: 'views/mytemplate'

The warning vanished. My theory is that this occurred because the page where the directive was used resided under "views" rather than "Views" in the route config function.

A similar issue occurred to me while working with .NET and MVC 5 until I realized that the problem was originating from the label in my Index.cshtml file:

<div data-ng-view=""></div>

If you are also facing this issue, check if the scripts section is being included again. To resolve this server-side problem, return a partial view like so:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Login()
    {
        return PartialView();
    }

    public ActionResult About()
    {
        return PartialView();
    }
}

It is crucial to modify the angular route '/' for optimal functionality! The issue lies in the fact that the base url request is set as '/'. By changing it to '/home' or '/hede', you can ensure that Angular operates smoothly.

When working on my project, I encountered a situation where I had an index.html file that included two separate views, view1.html and view2.html. Initially, I developed these views separately from index.html and then attempted to embed them using routes. However, I soon realized that having all the script files defined in both view html files was causing a warning. This warning disappeared once I removed the inclusion of angularJS script files from the views.

To summarize, it is best practice to include script files such as AngularJS, jQuery, and angular-route.js only in the index.html file and not in individual view html files.

One interesting scenario involves Webpack, which bundles Angular along with the existing angular loaded from the index.html <script> tag.

This happened because we were explicitly importing angular in multiple files:

define(['angular', ...], function(angular, ...){

As a result, webpack included it in the bundle as well. By consolidating all these imports to:

define([...], function(...){

We were able to resolve the issue of

Tried to Load Angular More Than Once

once and for all.

One issue I encountered was with the following line of code in HAML:

The problem here is that I had both an Angular ng-click and an href attribute set to "#" which redirects to the same page. To resolve this, all I needed to do was remove the href attribute and everything worked smoothly.

Instead of the correct:

I mistakenly had:

I attempted to remedy the problem by loading jQuery after Angular, as suggested earlier. However, this approach only suppressed the error message and did not resolve the issue. Moreover, jQuery's '.find' function was dysfunctional thereafter.

The solution finally emerged when I corrected the missing closing tag.
