[feature req] minifier fails if input folder contains anything else than html files

Hi!

If there are images in the input directory, html-minifier breaks. For example, I use npm script task:

html-minifier --input-dir ./test1 --output-dir ./test2 --html-5 --collapse-whitespace

There is only 1 html file and 1 png image in the folder test1/.

I get the following error:

Minification error on test1/test-icon.png
Parse Error: <����O��... (and goes on)...

I’d like to use html-minifier to minify my static website’s output folder — it contains everything that normal website would contain, including images.

If there is a temporary solution to feed only .html files from the folder into html-minifier, please advise as well, I’m keen to minify all my .html files.

Thank you.

Updated the title. I’ll see what I can do 😃

I am curious though - what is the expectation when skipping over non-HTML files. Do we just store minified files in the output directory, or are we expected to copy over image files etc.?

I have a Hugo-diven static website and I want to run the minifier on the whole /public/ folder — everything that is generated by Hugo. It’s necessary because HTML partials often have spaces everywhere, what adds up when rendered and looks clearly computer-generated with ten spaces, opening <div>, twenty spaces and fifteen line breaks, then some text…

Thanks again for sorting folder recursion + filtering by extension in v3.0.1, I really appreciate that!
