    two.js

    A renderer agnostic two-dimensional drawing api for the web

    Two.js is a two-dimensional drawing api geared towards modern web browsers. It is renderer agnostic enabling the same api to draw in multiple contexts: svg, canvas, and webgl.

    A curated collection of all country flags in SVG

    A curated collection of all country flags in SVG, plus the CSS for easier integration. For using the flags inline with text add the classes .fi and .fi-xx (where xx is the ISO 3166-1-alpha-2 code of a country) to an empty <span>. If you want to have a squared version flag then add the class fis as well. You could also apply this to any element, but in that case you'll have to use the fib instead of fi and you're set. This means that the flag is just going to appear in the middle of an...

    sharp

    High performance Node.js image processing module

    The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, AVIF and WebP images of varying dimensions. Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips. Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed. As well as image...
