SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
Closure Compiler follows the same line of thinking:

This minify/gzip size effect is a well known quirk to developers of javascript minifiers. The minifier's symbol mangling algorithm often has a more pronounced effect than does advanced AST optimization.
This website has real life data on the matter for popular libraries:

Compare the trophies indicating smallest size for Minified versus Minzipped (gzip). Generally the smallest minified size yields the smallest minified+gzip size, but there are some notable anomolies outside the range of statistical noise. It is not practical for a javascript minifier to take a compression algorithm into account - it would blow up the minify timings exponentially.
