Inline JS is not being minified

[javdl]

Hi, I would like to contribute a PR to minify inline JS. In the current form, HTML is being minified but any script tags are not. I know the place to add scripts is main.js most of the time, but in this case I want to add a measurement script that needs to be in the .
Besides, the Google Analytics script in the footer is also not being minified. So there's room left for optimization in both cases.
How do you think about this?

I tested this with https://www.npmjs.com/package/gulp-minify-inline Please let me know if you suggest a different package.
