A JavaScript mangler/compressor toolkit for ES6+.

note: You can support this project on patreon: [link] The Terser Patreon is shutting down in favor of opencollective. Check out PATRONS.md for our first-tier patrons.

Terser recommends you use RollupJS to bundle your modules, as that produces smaller code overall.

Beautification has been undocumented and is being removed from terser, we recommend you use prettier.

Why choose terser?

uglify-es is no longer maintained and uglify-js does not support ES6+.

terser is a fork of uglify-es that mostly retains API and CLI compatibility with uglify-es and uglify-js@3.

Install

First make sure you have installed the latest version of node.js (You may need to restart your computer after this step).

From NPM for use as a command line app:

npm install terser -g

From NPM for programmatic use:

npm install terser

Command line usage

terser [input files] [options]

Terser can take multiple input files. It's recommended that you pass the input files first, then pass the options. Terser will parse input files in sequence and apply any compression options. The files are parsed in the same global scope, that is, a reference from a file to some variable/function declared in another file will be matched properly.

Command line arguments that take options (like --parse, --compress, --mangle and --format) can take in a comma-separated list of default option overrides. For instance:

terser input.js --compress ecma=2015,computed_props=false

If no input file is specified, Terser will read from STDIN.

If you wish to pass your options before the input files, separate the two with a double dash to prevent input files being used as option arguments:

terser --compress --mangle -- input.js

Command line options

``` -h, --help Print usage information. --help options for details on available options. -V, --version Print version number. -p, --parse rties/specify mangler options: builtins Mangle property names that overlaps with standard JavaScript globals and DOM API props. debug Add debug prefix and suffix. keep_quoted Only mangle unquoted properties, quoted properties are automatically reserved. strict disables quoted properties being automatically reserved. regex Only mangle matched property names. only_annotated Only mangle properties defined with /*@__MANGLE_PROP__*/. reserved List of names that should not be mangled. -f, --format [options] Specify format options. preamble Preamble to prepend to the output. You can use this to insert a comment, for example for licensing information. This will not be parsed, but the source map will adjust for its presence. quote_style Quote style: 0 - auto 1 - single 2 - double 3 - original wrap_iife Wrap IIFEs in parenthesis. Note: you may want to disable negate_iife under compressor options. wrap_func_args Wrap function arguments in parenthesis. -o, --output Output file path (default STDOUT). Specify ast or spidermonkey to write Terser or SpiderMonkey AST as JSON to STDOUT respectively. --comments [filter] Preserve copyright comments in the output. By default this works like Google Closure, keeping JSDoc-style comments that contain e.g. "@license", or start with "!". You can optionally pass one of the following arguments to this flag: - "all" to keep all comments - false to omit comments in the output - a valid JS RegExp like /foo/ or /^!/ to keep only matching comments. Note that currently not *all* comments can be kept when compression is on, because of dead code removal or cascading statements into sequences. --config-file Read minify() options from JSON file. -d, --define [=value] Global definitions. --ecma Specify ECMAScript release: 5, 2015, 2016, etc. -e, --enclose [arg[:value]] Embed output in a big function with configurable
