  • sharp

    High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, AVIF and TIFF images. Uses the libvips library.

    Project mention: How to generate dynamic OG (OpenGraph) images with Satori and React | dev.to | 2024-06-27

    If necessary, you will need to return it as an image by itself. For that, we can use the sharp to handle it for yourself. See the example below:

  • react-virtualized

    React components for efficiently rendering large lists and tabular data

    Project mention: The Secret Weapon of Top Developers: 7 React JS Libraries You Can't Afford to Ignore | dev.to | 2024-02-21

    You may increase the rendering efficiency of tabular and huge list data by using the React Virtualized module. React apps perform better overall when the quantity of requests and DOM elements is limited. React Virtualized is comparable to many other tools; however, what sets it apart from the competition is the sheer volume of features and excellent upkeep.

  • ava

    Node.js test runner that lets you develop with confidence 🚀

    Project mention: Painless CLI integration testing | dev.to | 2024-01-10

    We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

    Developers also employ alternative methods for lazy loadings, such as the scroll event listener, besides the Intersection Observer API and the loading property. Unlike the Intersection Observer API, which only monitors the elements targeted for lazy loading, developers attach a scroll event listener to every element on the page. Once the element marked for lazy loading is within the visibility range of the user, a function is invoked to switch the image or video URL with the attribute previously holding it, just like with the Intersection Observer API. This approach is costly for a web project. As the developer seeks to optimise page load by integrating lazy loading to some elements on the webpage, the developer slows down the page's performance due to multiple firing of an event as the function meets each element. Moreover, packages for JavaScript that deal with lazy loading exist. For instance, the LazyLoad library uses the Intersection Observer API, a lightweight JavaScript library. It supports many lazy loading features, such as preloading, responsive image loading, and custom loading animations. Additional lazyloading libraries include Yall.js, Lozad.js, LazyLoad XT for jQuery, and many more.
