blurhash-to-css-gradient

A zero-dependency function that converts a Blurhash value to a CSS gradient string, which can be used as an image placeholder background. While other blurhash libraries are available, this one is designed only for the decoding part. If you are building frontend applications, this library is for you.

Usage

import { blurhashToCssGradient } from 'blurhash-to-css-gradient';

const blurhash = 'UCHeUgK5ox~q~qX70Kod4=jFRPMx9bxuaLIU'; // this might be generated from your CMS like caisy.io
const backgroundColor = blurhashToCssGradient(blurhash);
console.log(backgroundColor);
