Compactor - Frontend compression without pain

Compactor is a efficient alternative to generate fully compressed HTML projects, including all JS, CSS images and ony other resource files.

It was primary designed to work with static websites where you don't have, don't need or don't want to use NodeJS and their crap system but you can also use it with your server side rendered website.

The ideia is very simple: you give the root folder of the project, and compactor builds the compressed version of the project for you with all possible optimizations. Start with no configuration needed.

• Compress images in GIF, JPG, JPEG, PNG and SVG format.
• Automatically create WEBP copy from JPG, JPEG and PNG as progressive enhancement.
• Watch mode for automation and live development.
• CLI flags to fine tuning control.
• Just works!

RoadMap (In Development)

• HTML include feature for code splitting.
• A way of create source-map for HTML (maybe simple comment).
• Single output from multiple files for SASS and TypeScript (these languages does not include it out of the box, you have to use a 'index' file).
• Single output and merge for JSON, XML e SVG.
• Avif copy format from others images formats.

CLI - Installation and Usage

For now, you first need to install dependencies:

sudo apt install -y nodejs npm libjpeg-progs

Then download the most recent binary file and make it executable:

GIT_URL=https://raw.githubusercontent.com/mateussouzaweb/compactor
sudo wget $GIT_URL/master/bin/compactor -O /usr/local/bin/compactor
sudo chmod +x /usr/local/bin/compactor

Done! To check command flags use:

compactor --help

To compress a project source into a destination, run:

compactor \
    --source /path/to/source/ \
    --destination /path/to/destination/

To watch live changes while developing a project, add the watch flag:

compactor \
    --watch
    --source /path/to/source/ \
    --destination /path/to/destination/

File Mappings and Bundles

If you are using custom file mappings or package bundle features, please make sure to require the correct file or path in our HTML files and related code that require such files. You should always use the final file path.

For example, if you have 2 scripts (lib.js and events.js) that are merged and placed in scripts.js by compactor, set the reference of the file like bellow:

<script src="scripts.js"></script>

The same applies to CSS, JS files or any other file that use others files as reference:

/* CSS */
.bg {
    background-image: url('final-name.png')
}

// JS
required('bundled.js')

That is it! Enjoy!
