FileMelt 📁🔥

An everything minifier for websites implemented in Python.

Pros	Cons
Write clean code without paying for extra bandwidth	Output folder increases git repo size quickly (but can be added to .gitignore)
Minifies HTML, CSS, JS, SVG	JS minifier is imperfect (but can be disabled)
Decreases load speeds

How it works

The only file you need is FileMelt.py. Add it to your repository, and assign the input and output directories at the top of the file (and optionally modify the settings also in the file). Each time you run FileMelt.py, it will generate a minfied output directory of all files in the input directory, including files that FileMelt cannot minify (yet). Work in your input directory and host in your output directory to minimize bandwidth costs with zero impact on development.

Contributing

This repo is active! All PRs will be reviewed ASAP. All the code is in FileMelt.py (this project is 100% Python). The source and docs folders are full of input/output test cases. Implement a roadmap feature, minify a new file type, or make any general improvement.

Roadmap:

• Basic HTML minification.
• CSS minification.
• Remove html comments.
• Minify style tag.
  • Remove type="text/css".
  • Remove spaces and newlines.
• Minify hexcodes in style attributes.
• Setting for removing console.log statements
