Using the largest, unminified, single file I could find in my node_modules folder (which happened to be tsserver.js from typescript, 11mb and 185 000 lines long)

Raw: 11 403KiB

Raw gzipped: 1 881 KiB

Minified: 3 543 KiB

Minified gzipped: 865 Kib

A 2.17x reduction between the two gzips

Even with GZip, minification is huge

Most people aren't making webpages that need a quarter million lines of JS. For a normal sized webpage, difference between raw gzipped and minified gzipped is negligable.

Or maybe even "modern front end" hello world apps now need a quarter of a million lines because "modern" JS devs use super mega react typescript which installs 1000 npm dependencies and requires a 30 second "build" to generate a huge monolithic minified tree-shook js blob. I wouldn't know, I just use vanilla JS for my web pages.

Okay. Let's move goalposts.

For a small file (github.com/runk/node-chardet, release version 0.7.0, index.js, 154lines, 4KiB)

Raw - 3.30 KiB

Minified - 2.05 KiB

Gz - 1.01 KiB

Minified+Gz - 0.81 KiB

That's a 25% reduction

Still huge. If minifying before gzipping multiples the size of my transfers by a factor between 0.75 and 0.40, I'm not skipping it for the one oddball that wants the sources in a human-readable format on the production environment

They can use the sourcemaps, or find the files on github

Saving 200 bytes is "still huge"? For me 200 bytes is not worth the extra headaches minification introduces.
