If you want to process Javascript outside of the browser you can use
node.js and other
V8 engines.
Node.js is a JavaScript runtime built on
Chrome's V8 JavaScript engine.
Quote:
V8 is Google's open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

Since publication of the first edition in 1997, ECMAScript has grown to be one of the world's most widely used general-purpose programming languages. It is best known as the language embedded in web browsers but has also been widely adopted for server and embedded applications.

JavaScript::Minifier(3pm) User Contributed Perl Documentation JavaScript::Minifier(3pm)
NAME
JavaScript::Minifier - Perl extension for minifying JavaScript code
SYNOPSIS
To minify a JavaScript file and have the output written directly to another file
use JavaScript::Minifier qw(minify);
open(INFILE, 'myScript.js') or die;
open(OUTFILE, '>myScript-min.js') or die;
minify(input => *INFILE, outfile => *OUTFILE);
close(INFILE);
close(OUTFILE);
To minify a JavaScript string literal. Note that by omitting the outfile parameter a the minified code is returned as a string.
my minifiedJavaScript = minify(input => 'var x = 2;');
To include a copyright comment at the top of the minified code.
minify(input => 'var x = 2;', copyright => 'BSD License');
To treat ';;;' as '//' so that debugging code can be removed. This is a common JavaScript convention for minification.
minify(input => 'var x = 2;', stripDebug => 1);
The "input" parameter is manditory. The "output", "copyright", and "stripDebug" parameters are optional and can be used in any combination.
DESCRIPTION
This module removes unnecessary whitespace from JavaScript code. The primary requirement developing this module is to not break working
code: if working JavaScript is in input then working JavaScript is output. It is ok if the input has missing semi-colons, snips like '++ +'
or '12 .toString()', for example. Internet Explorer conditional comments are copied to the output but the code inside these comments will
not be minified.
The ECMAScript specifications allow for many different whitespace characters: space, horizontal tab, vertical tab, new line, carriage
return, form feed, and paragraph separator. This module understands all of these as whitespace except for vertical tab and paragraph
separator. These two types of whitespace are not minimized.
For static JavaScript files, it is recommended that you minify during the build stage of web deployment. If you minify on-the-fly then it
might be a good idea to cache the minified file. Minifying static files on-the-fly repeatedly is wasteful.
EXPORT
None by default.
Exportable on demand: minifiy()
