This is a CLI to run BlurHash utility commands in your terminal. This includes encoding image files into a BlurHash string, decoding a BlurHash string into an image file, and validating BlurHash strings.
$ npm install -g bh-cli
$ bh encode [options] <image_file>
$ bh decode [options] <blurhash>
$ bh validate <blurhash>
Go for it!
All credit goes to the BlurHash and sharp packages, I just smushed the two together into a CLI.
