![]() I’ve added comments to explain what’s going on. import lozad from 'lozad' export default Ībove you can see the code of the AppImage component. In my opinion, this is a good enough fallback, but you can also use a polyfill if you want. Keep in mind, though, that not every browser (most notably Safari) supports the Intersection Observer API yet, but Lozad.js degrades very gracefully by simply loading all images immediately if the browser does not support the Intersection Observer API. The JavaScript Flash Detection Library (Flash Detect) and JavaScript Flash HTML Generator Library (Flash TML) are a legible, maintainable and standards compliant markup solution. Lozad.js has a very small footprint of only 1.8 kB and it’s very fast because it uses the Intersection Observer API. Building a custom lazy loading componentīecause we don’t want to implement the logic for detecting if an image is in the viewport, and therefore should be loaded, ourselves, we use Lozad.js to handle this for us. ![]() For those of you who’re constantly searching for ways of how to shave off a few kilobytes of your application or who’re interested in how to build stuff themselves, read on. As a remedy, we present Gordon, a method for the comprehensive analysis and detection of Flash-based. If a few kilobytes are not a great concern for you and if you’re not interested in how to actually build a lazy loading component, you can stop reading and just use Vue-Lazyload, it’s a great plugin. Adobe Flash Player increasingly su ers from vulnerabilities, and attacks using Flash-based malware regularly put users at risk of being remotely attackedmost prominently highlighted by numerous exploits made pub-lic during the past months. The custom solution only adds about 5 kb (overall bundle size: 92 kB). In the tests that I’ve done, Vue-Lazyload adds about 19 kB to the final bundle size (overall bundle size: 106 kB). The reason why I’m still writing this article is, that I wanted a more lightweight solution. If you don't do this, browsers that don't support the features you are using. Vue-Lazyloadīefore we get started: there already is a perfectly fine solution for lazy loading images with Vue.js: Vue-Lazyload. The idea behind feature detection is that you can run a test to determine whether a feature is supported in the current browser, and then conditionally run code to provide an acceptable experience both in browsers that do support the feature, and browsers that don't. If you want to take a look at the result of our work, you can look at a demo hosted on Netlify and you can check out the code on GitHub.
