Angular 17 Defer block: Create a Lazy-loaded Youtube Player for a blog!
Today, we’re going to discuss how to create a lazy-loaded Youtube player for a blog using Angular 17’s defer block feature. This technique can help improve the performance of your blog by only loading the Youtube player when it’s needed, rather than loading it immediately when the page is loaded.
The first step is to ensure you have the Angular framework installed. You can do this by adding the following script tag in the head section of your HTML document:
Next, you’ll want to create a new component for your lazy-loaded Youtube player. Here’s an example of how to create a simple component using Angular’s defer block:
angular.module('lazyYoutubePlayer', [])
.controller('PlayerController', function($scope, $sce) {
$scope.youtubePlayer =
$scope.trustedUrl = $sce.trustAsResourceUrl('https://www.youtube.com/embed/videoId');
})
In this example, we create a new Angular module called ‘lazyYoutubePlayer’ and define a controller called ‘PlayerController’. Inside the controller, we use the $sce service to mark the Youtube video URL as a trusted resource and then bind it to the ng-bind-html directive within the view.
Finally, you’ll want to add the necessary CSS and JavaScript to style and initialize the Youtube player when it’s loaded. Here’s an example of how you might do this:
.youtube-player {
width: 100%;
height: 400px;
}
.youtube-player iframe {
width: 100%;
height: 100%;
}
By using Angular 17’s defer block feature, you can improve the performance of your blog by lazy-loading the Youtube player only when it’s needed. This can help reduce the initial page load time and improve the overall user experience.
