Blog minification in a fancy way with PowerShell

There is no built-in support for minification in Hugo engine, which isn’t a bad thing on its own. But I had to figure out a way to minify my files while keeping building and maintenance extremely simple.

At first point I added minify for text files. It’s a single binary (written in Go), and with a single call it can run recursively over Hugo’s public folder, minifying output files in-place, just as I needed.

But minifying images is a more tricky task. I decided to use jpegtran and optipng, but they can’t be run recursively. Some scripting is required to use them. While the task of finding all the images in a folder and applying minifiers on them is trivial and can be solved with PowerShell one-liner, it was not satisfying enough, so I end up with the thing described below in this post.

Additional motivation is to have a tool that can be adopted easily to any other processing task and will give me a fancy progress report.
