Is it really worth minifying your HTML?
Just using gzip is good enough. You can do more, but it's a lot of work and there just isn't much to gain. Your time is better spent elsewhere, More on reddit.com

March 8, 2014How come none of the websites does HTML minification?
There's usually a lot to gain by minifying JavaScript and CSS. Most HTML files are pretty small anyway. And when they aren't, it's because there's a half meg of text that you can't minify. Unless you for some reason have hundreds of lines of comments there isn't much to gain. More on reddit.com

August 17, 2016How do I "minify" JS and CSS and combine them into one file?
Well, it will always be two files. You will have a minified JS and a minified CSS file. It won't be a single file concatenated. I use Grunt JS for my automated minification process. then you have CSSmin for CSS and Uglify for JS. I'd also recommend you use a tool like JSHint for JS validation and CSSLint for CSS validation. And, although I've never used it, there is the YUI Compressor that can handle both CSS & JS minification. There are also a ton of other plugins to automate your life using Grunt, so I'd recommend checking out their plugin repo - http://gruntjs.com/plugins Good Luck! More on reddit.com

This is quite a slow video. So I made these timestamps.
-
0.55 - minified code is unreadable (skips "what is JS and what is a minifier").
-
1.43 - minifying strips licences breaking library licences (that's not true. Badly configured minifying will strip licences.).
-
3.00 - gzip > minifying.
-
3.51 - gzip Vs uglifyjs.
-
4.40 - gzip Vs minifying then gzip (no data provided).
-
5.02 - gzip decompression speed.
-
5.40 onwards - some points at the end about build chains potentially breaking (I don't think browser native tech is quite ready to provide a "raw source" type delivery of JS). Some more points on licences breaking due to being omitted during the build chain.
No real points not to minify.
No hard evidence that minifying is bad - other than potential licensing issues, potential broken build chains, and that it makes it harder for users to learn from your code.

JavaScript Minify – Minifying JS with a Minifier or jsmin
November 2, 2022 - By minifying your JavaScript files, you can improve resource load times as the browser will require less time to completely download such files. When the browser fetches a JavaScript file, the JavaScript engine first tries to parse the file. Parsing involves going through the code line by line, explicitly ignoring whitespaces and comments, and checking if the code is syntactically correct.
