Dev Useful Stuff

SQIP - CLI utility that generates a lighweight preview for a given image in SVG format. Have you ever seen how Google, Pinterest or Facebook preload their pictures? Say, you open Google and search for a picture, the results appear in grid and each image has its own colored placeholder and only then the real image is loaded replacing the placeholder. It is very nice practice from UX point of view. The use case of SQIP is pretty simple. Firsly you need to generate the SVG preview: sqip -o output.svg ../myImage.jpg then, you calculate base64 from it: cat output.svg | base64 and now you can use it in your HTML code, something like this: <img width="600" height="400" src="myImage.jpg" style="background-size: cover; background-image: url(data:image/svg+xml;base64,PHN2ZyB4bWx....0iMjciLz48L2c+PC9zdmc+);"> And here you go! #js #images #svg https://github.com/technopagan/sqip
