UGLIFY-JS(1)

🌸 NAME 🌸

okay so bestie, welcome to uglify-js — that's the manual page, section 1, the whole User Commands situation 💅 — and she is literally a JavaScript parser, mangler/compressor and beautifier toolkit. all of that. one tool. main character energy fr fr 👑

✨ SYNOPSIS ✨

uglifyjs [files...] [options]

---

💖 OPTIONS 💖

• -h, --help — prints the usage info. want the deets on every single option available? hit --help options and she'll spill 🫶
• -v, -V, --version — prints the version number. three whole ways to ask, iconic.
• -p, --parse <options> — specify parser options.
• -c, --compress [options] — enable the compressor / specify compressor options.
• -m, --mangle [options] — mangle names / specify mangler options.
• --mangle-props [options] — mangle properties / specify mangler options.
• -b, --beautify [options] — beautify the output / specify output options.
• -O, --output-opts <options> — output options, but with beautify disabled.
• -o, --output <file> — the output file. default is STDOUT, no cap.
• --annotations — process and preserve comment annotations.
• --no-annotations — ignore and discard comment annotations.
• --comments [filter] — preserve copyright comments in the output. gotta protect the legal vibes ✨
• --config-file <file> — read minify() options from a JSON file.
• -d, --define <expr>[=value] — global definitions.
• -e, --enclose [arg[,...][:value[,...]]] — embed everything in a big function, with configurable argument(s) & value(s).
• --expression — parse a single expression, rather than a program.
• --ie — support non-standard Internet Explorer. yes bestie, that Internet Explorer 😭
• --keep-fargs — do not mangle/drop function arguments.
• --keep-fnames — do not mangle/drop function names. useful for code relying on Function.prototype.name.
• --module — process input as an ES module (implies --toplevel).
• --no-module — process input with improved JavaScript compatibility.
• --name-cache <file> — file to hold mangled name mappings.
• --rename — force symbol expansion.
• --no-rename — disable symbol expansion.
• --self — build UglifyJS as a library (implies --wrap UglifyJS).
• --source-map [options] — enable source map / specify source map options.
• --timings — display operations run time on STDERR.
• --toplevel — compress and/or mangle variables in toplevel scope. going all the way up, periodt.
• --v8 — support non-standard Chrome & Node.js.
• --validate — perform validation during AST manipulations.
• --verbose — print diagnostic messages.
• --warn — print warning messages.
• --webkit — support non-standard Safari/Webkit.

🛠️ (internal debug use only)

these two are not for casual usage bestie, they're the backstage pass 🎀

• --in-situ — warning: replaces original source files with minified output. like, it will eat your originals. be so careful, this is not a drill 💀
• --reduce-test — reduce a standalone test case (assumes cloned repository).

ngl this is the whole page. no options skipped, no flags dropped, we did not play about it 🫶

and that's a wrap, bestie — this was uglify-js version 3.19.3, from April 2026, and you just read the whole thing. slay, ate, left no crumbs 💖✨🎀🦋
