How can I add comments in AngularJS without making them visible in the source code?

When working with JSPs, I always opt for <%-- --%> over <!-- --> when adding comments to ensure they do not appear in the final HTML output. Now that I'm diving into using AngularJS, I find myself wondering if there is a similar method for commenting that I could utilize. While it's not crucial for the comments to remain hidden in the HTML source, I prefer keeping them out of sight.

Having only just started exploring AngularJS, I am unsure if there are any techniques to prevent comments from appearing in the HTML source. I simply wanted to inquire about this and also learn more about any best practices related to commenting in AngularJS. Any insights on this would be greatly appreciated.

Answer №1

AngularJS is a powerful tool for adding dynamic elements to HTML, JavaScript, and CSS pages. Unlike JavaServer Pages, AngularJS does not rely on a templating language and therefore does not have its own unique syntax for comments. However, developers can still implement standard HTML-style comments within their code.

Answer №2

One recommended practice is to utilize a pre-deployment processing tool like grunt uglify. This tool offers the ability to remove unnecessary comments and perform essential deployment tasks such as code minification.

Answer №3

Utilize directives:

myApp.directive('customDirective', ['$rootScope', function($rootScope) {

    return {
        restrict: 'E',
        link: function($scope, element, attrs){
            $(element).hide();
        }
    };
}]);

illustrative example:

<customDirective>Hide me</customDirective>
