Having difficulty making my directive function in Angular

I'm encountering an issue with my directive not working properly. I suspect that I may have registered it incorrectly, but I can't seem to figure out the mistake. Could it be related to the naming convention? Here's the code snippet in question -

My Directive -

'use strict';

angular.module('demoApp')
.directive('packeryAngular', ['$rootScope', '$timeout',
function($rootScope, $timeout) {
return {
  restrict: 'A',
  scope: true,
  link: function(scope, element, attrs) {

};

}
]);

When using this directive on a div like so

<div packeryAngular>

However, nothing happens as expected. I thought registering it on my app might be the solution, like this:

angular.module('demoApp', [ 'packeryAngular ']

But doing so results in the following error in the console :

Error: [$injector:modulerr] Failed to instantiate module packeryAngular due to:
Error: [$injector:nomod] Module 'packeryAngular' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

As a newbie in this field, I'm struggling to find the root cause of the issue here. Despite trying to follow other examples closely, I haven't been successful. Any assistance would be greatly appreciated. Thank you for taking the time to read!

Answer №1

No need to manually inject the directive, simply include it in your HTML code. The second word in the directive should start with a lowercase letter, followed by hyphens before each subsequent capital letter. For example, YourCustomDirective should be written as your-custom-directive.

<div my-custom-angular-directive>

Avoid injecting the directive in the module declaration.

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

Answer №2

To ensure proper functionality, be sure to include the following attribute on your element:

<div angular-packery>

When defining directives in AngularJS, it is important to use lower camel case for directive names. However, HTML is not compatible with uppercase letters in attribute names, so AngularJS requires that any uppercase letter be replaced by a dash followed by its corresponding lowercase letter.

For example, if your directive name in JavaScript code is myDirectiveName, in your HTML code it should be referenced as my-directive-name.
