klamar/compress repository overview

⁠Usage

docker run --rm -v `pwd`:/work klamar/compress
docker run --rm -v `pwd`:/work klamar/compress --verbose

The compressor inside the docker image is compressing everything in the /work directory. So mount the directory you want to run the compressor against into the /work directory.

By default the script will ensure the compressed files:

• have the same owner like the original one (uid/gid)
• have the same creation time
• have the same file permissions (chmod)

⁠Command line flags

• -v|--verbose Enable debug output
• -e|--exclude exclude files matching this given pattern (e.g.: --exclude="*.jpg,dir/*")
• -h|--help Shows some help information
• --follow-symlinks follows symbolic links (default=no follow)
• --no-png Skip png optimization
• --no-gzip Skip gzip compression
• --no-brotli Skip brotli compression

⁠Compressions perfomed

⁠gzip

Every file will get a gzip counterpart compressed with highest compression level (gzip -9)

foo.css -> foo.css.gz

⁠brotli

Every file will get a brotli counterpart compressed with highest compression level (brotli --quality 11)

foo.css -> foo.css.br

⁠png

PNG files are getting optimized using optipng with optimization level 5.

foo.png -> foo.png.orig (original)
foo.png (optimized using optipng)
