✎ Unhar - Extract, Unminify, Beautify Javascript files from .Har file

In the previous post, I explained my approach to capturing and downloading a website’s JavaScript resources into a .HAR file for further local analysis. Now, let’s take it a step further with unhar and process that HAR files.

unhar turns a raw .HAR file into a structured set of web assets for local analysis. It extracts unique JavaScript and HTML resources while preserving the original URL structure, fetches available source maps, beautifies/unminifies JavaScript, and extracts inline scripts from HTML pages.

In short: HAR → Extract → Source Maps → Beautify → Ready for Analysis

● Installation

git clone https://github.com/Spix0r/unhar

● Usage

# custom output directory
python3 unhar.py site.har --output folder

# skip source map fetching
