A tool for compressing files by means of Brotli and Gzip algorithms, works seamlessly with many CLI UI tools (Angular CLI, Vue CLI, create-react-app).
The flexibility of the algorithms could be extended by many options flags, including the gzip-level, gzip-strategy, gzip-memory-level, brotli-param-mode, brotli-quality, brotli-size-hint. All flags can be declared via ENV variables (ENV variables have higher priority over CLI arguments).
You can enable verbose mode for better visual representation, customize your file output using output-file-format or compress with incremental flag if you have a lot of files that rarely change.
By default gzipper compress all the files but you could use include or exclude options for flexibility.

gzipper c --incremental ./dist
A special type of compression that significantly decreases the time of compression (on the second run) if you have a lot of big and rarely updated files. It creates a .gzipper folder with pre-compressed files (cache) and config that stores all necessary metadata (.gzipperconfig).
gzipper c --verbose ./dist
Get more information about executed work. (Could increase time of compression because of gathering additional metrics)
gzipper c --exclude jpeg,png,ico ./dist
Exclude file extensions from compression (compression extensions like gz, zz, br, etc. excluded by default), example: jpeg,jpg...
gzipper c --include jpeg,png,ico ./dist
Include file extensions for compression(exclude others), example: js,css,html...
gzipper c --threshold 900 ./dist
Exclude assets smaller than this byte size. 0 (default)
gzipper c --gzip ./dist
Enable gzip compression. (default behavior)
gzipper c --deflate ./dist
Enable deflate compression.
gzipper c --brotli ./dist

gzipper c --gzip-strategy 3 ./dist
Gzip compression strategy 0 (default), 1 (filtered), 2 (huffman only), 3 (RLE), 4 (fixed)
gzipper c --deflate-level 8 ./dist

Output file format with artifacts, default format: [filename].[ext].[compressExt]. Where: filename -> name of your file, ext -> file extension, compressExt -> compress extension (.gz, .br, etc), hash -> uniq hash.

Removes compressed files that larger than uncompressed originals in your directory.
Ignores compressed files that have already exist in your directory. Works only with default --output-file-format.
Spawn workers for parallel compression, be aware of workers number because every worker creates an additional thread. More info there.

gzipper cache purge
Removes all pre-compressed files from cache that was generated via --incremental flag.
gzipper cache size
Returns the size of all pre-compiled files from cache.
