Gzipper

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 better flexibility.

Examples

CLI

Globally usage

gzipper compress [options] <path> [outputPath]

Locally usage

Add module to scripts in your package.json and run compress command npm run compress.

  "scripts": {
    "gzipper": "gzipper",
    "compress": "gzipper compress ./dist"
  }

Use npx command.

  "scripts": {
    "compress": "npx gzipper compress ./dist"
  }

UI build tools (e.g. Angular CLI)

  "scripts": {
    "build": "ng build && gzipper compress ./dist"
  }

Compress files to a certain directory ./gzipped (folders structure inside dist will be saved)

  "scripts": {
    "build": "ng build && gzipper compress ./dist ./gzipped"
  }

Compress files to very deep folder ./very/deep/folder (all folders will be automatically created if not exist)

  "scripts": {
    "build": "ng build && gzipper compress ./dist ./very/deep/folder"
  }

Compress a single file

  "scripts": {
    "build": "ng build && gzipper compress ./dist/awesomeness.txt"
  }

Node.js Module

const { Compress } = require('gzipper');
const gzip = new Compress('./test', './dist', { verbose: true });

try {
  const files = await gzip.run();
  console.info('Compressed files: ', files);
} catch (err) {
  console.error(err);
}

Run multiple algorithms at the same time.

const { Compress } = require('gzipper');
const gzip = new Compress('./test');
const brotli = new Compress('./test', null, { brotli: true });

try {
  const [gzipFiles, brotliFiles] = await Promise.all([
    gzip.run(),
    brotli.run(),
  ]);
  console.info('Compressed gzip files: ', gzipFiles);
  console.info('Compressed brotli files: ', brotliFiles);
} catch (err) {
  console.error(err);
}

ENV Variables have higher priority over CLI arguments.

--incremental

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).

-v, --verbose

gzipper c --verbose ./dist

Get more information about executed work. (Could increase time of compression because of gathering additional metrics)

-e, --exclude

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...

-i, --include

gzipper c --include jpeg,png,ico ./dist

Include file extensions for compression(exclude others), example: js,css,html...

-t, --threshold

gzipper c --threshold 900 ./dist

Exclude assets smaller than this byte size. 0 (default)

--level

gzipper c --level 8 ./dist

Compression level 6 (default), 0 (no compression) - 9 (best compression)

--memory-level

gzipper c --memory-level 2 ./dist

Amount of memory which will be allocated for compression 8 (default), 1 (minimum memory) - 9 (maximum memory)

--strategy

gzipper c --strategy 3 ./dist

Compression strategy 0 (default), 1 (filtered), 2 (huffman only), 3 (RLE), 4 (fixed)

--deflate

gzipper c --deflate ./dist

Enable deflate compression.

--brotli

gzipper c --brotli ./dist

Enable brotli compression, Node.js >= v11.7.0.

--brotli-param-mode

gzipper c --brotli-param-mode text ./dist

Available values are default, text (for UTF-8 text), font (for WOFF 2.0 fonts), only for --brotli

--brotli-quality

gzipper c --brotli-quality 10 ./dist

Brotli compression quality 11 (default), 0 - 11, only for --brotli

--brotli-size-hint

gzipper c --brotli-size-hint 6 ./dist

Expected input size 0 (default), only for --brotli

--output-file-format

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.

--remove-larger

Removes compressed files that larger than uncompressed originals in your directory.

--skip-compressed

Ignores compressed files that have already exist in your directory. Works only with default --output-file-format.

Cache

Command
`purge`
`size`

purge

gzipper cache purge

Removes all pre-compressed files from cache which was generated via --incremental flag.

size

gzipper cache size

Returns the size of all pre-compiled files from cache.
