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.

ENV Variables have higher priority over CLI arguments.
gzipper c ./src --incremental
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 ./src --verbose
Get more information about executed work. (Could increase time of compression because of gathering additional metrics)
gzipper c ./src --exclude jpeg,png,ico
Exclude file extensions from compression (compression extensions like gz, zz, br, etc. excluded by default), example: jpeg,jpg...
gzipper c ./src --include jpeg,png,ico
Include file extensions for compression(exclude others), example: js,css,html...
gzipper c ./src --threshold 900
Exclude assets smaller than this byte size. 0 (default)
gzipper c ./src --gzip
Enable gzip compression. (default behavior)
gzipper c ./src --deflate
Enable deflate compression.
gzipper c ./src --brotli
Enable brotli compression.
gzipper c ./src --zopfli
Enable zopfli compression.
gzipper c ./src --gzip-level 8
Gzip compression level 6 (default), 0 (no compression) - 9 (best compression)
gzipper c ./src --gzip-memory-level 2
Amount of memory that will be allocated for gzip compression 8 (default), 1 (minimum memory) - 9 (maximum memory)
gzipper c ./src --gzip-strategy 3
Gzip compression strategy 0 (default), 1 (filtered), 2 (huffman only), 3 (RLE), 4 (fixed)
gzipper c ./src --deflate-level 8
Deflate compression level 6 (default), 0 (no compression) - 9 (best compression)
gzipper c ./src --deflate-memory-level 2
Amount of memory that will be allocated for deflate compression 8 (default), 1 (minimum memory) - 9 (maximum memory)
gzipper c ./src --deflate-strategy 3
Deflate compression strategy 0 (default), 1 (filtered), 2 (huffman only), 3 (RLE), 4 (fixed)
gzipper c ./src --brotli-param-mode text
Available values are default, text (for UTF-8 text), font (for WOFF 2.0 fonts), only for --brotli
gzipper c ./src --brotli-quality 10
Brotli compression quality 11 (default), 0 - 11, only for --brotli
gzipper c ./src --brotli-size-hint 6
Expected input size 0 (default), only for --brotli
gzipper c ./src --zopfli-num-iterations 15
Maximum amount of times to rerun forward and backward pass to optimize LZ77 compression cost. Good values: 10, 15 for small files, 5 for files over several MB in size or it will be too slow, only for --zopfli
gzipper c ./src --zopfli-block-splitting
If true, splits the data in multiple deflate blocks with optimal choice for the block boundaries. Block splitting gives better compression, only for --zopfli
gzipper c ./src --zopfli-block-splitting-last
If true, chooses the optimal block split points only after doing the iterative LZ77 compression. If false, chooses the block split points first, then does iterative LZ77 on each individual block. Depending on the file, either first or last gives the best compression, only for --zopfli
gzipper c ./src --zopfli-block-splitting-max 5
Maximum amount of blocks to split into (0 for unlimited, but this can give extreme results that hurt compression on some files), only for --zopfli
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.
Example: Expected project structure.

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.
