Image compression executable to run as pre or post-commit. Compresses images in the same place, builds hash-manifest and stages changed images.

npm install --save-dev https://github.com/moovel/compressify.git

Image compression can run as standalone CLI command or used in combination with husky as pre-commit. It will try to read the --manifest file and filter the already compressed images. The remaining images in the pipe will be compressed using mozjpeg and added to the stage. After compression takes place the hash manifest will be recreated, added to the stage and everything is committed.
