Angularjs 1.2 $injector:modulerr

Routing dependencies: The right sidekick for Angular 1.2

Routing in AngularJS 1.2 demands the sidekick, ngRoute module, to hop in onto the stage. Since version 1.1.6, ngRoute operates independently. So, always:

• Befriend angular-route.min.js using <script> tag:

<script src="angular-route.min.js"></script>


• Invite ngRoute to your main module's awesome party:

angular.module('myApp', ['ngRoute']);
// Who doesn't love partying with ngRoute, right? 🎉


$injector:modulerr appears when ngRoute feels left out. AngularJS 1.2.0rc1 or later versions take good care of ngRoute.

Consistency and order: the key to peace

Keep your app naming rituals consistent. AngularJS plays the strict enforcer when it comes to module names, any oversight and you face the wrath of the modulerr. Match your ng-app in HTML, with your JavaScript file, every time.

Just like your morning cereal comes before milk, load your AngularJS script before your app to avoid spoiling your day with $injector:modulerr. Prior proper planning saves seconds of sorrow.

Organized and secure with IIFE

IIFE (Immediately Invoked Function Expression) capsulates modules, keeping away global scope contamination, much like your antivirus keeps off sneaky malware. It prevents uninvited guests from crashing your app party:

(function(){
    angular.module('myApp', ['ngRoute']);
    // ...rest of your top-secret code...
})();
// You enter the bloc, you follow the rules. 🕶️

Version matchmaking

Ensure your AngularJS version pairs well with your preferred modules. $routeProvider and $locationProvider share a good cocktail with ngRoute in AngularJS 1.2. Similar to avoiding spicy food with your martini, keep your version compatibility complimentary.

Debug, debug, debug

Those hidden bugs of typos, missing files, or incorrect configurations in your app.config can give you the $injector:modulerr hiccups. Debug your code, scrutinize each line, every variable, no stone unturned. Using developer tools and good old console logs can be your magnifying glass in this detective work.
