I've used online diff checkers in the past for their convenience, but in the end I went out of my way to find a convenient way to quickly diff two texts locally. It's not that I believe that online diff checkers upload the contents to some third parties - in fact this one explicitly says everything is performed locally - but the fact that they _could_ made me feel uneasy.
I've been looking for an npm package that makes char-by-char diffs for small chunks of text like this, for a CLI script that generates HTML reports. Is there one in particular that you used?
Hey, congrats on shipping!
What do you think is the most likely use case for this?
