uglify-lite

library2017.2.19jsnpmunverified

A browser-compatible, zero-dependency JavaScript minifier based on UglifyJS v1.3.5. Version 2017.2.19, released as a snapshot of the ancient UglifyJS 1.x branch. It packages the old minifier for use in both Node.js and browser environments via a bundled rollup file. Key differentiator: no dependencies and includes a CDN-ready bundle, but it's a very old version of UglifyJS (v1 from 2013), lacking ES6+ support and modern optimizations. Release cadence: last published in 2017 and appears abandoned.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ const uglify = require('uglifyjs-lite');

✗ import uglify from 'uglifyjs-lite';

Package does not provide ESM exports; only CommonJS require() works. Browser usage should use the CDN bundle instead.

minify

✓ const uglify = require('uglifyjs-lite'); const result = uglify.minify('code');

✗ const { minify } = require('uglifyjs-lite');

The API exposes `minify` as a method on the default export, not as a named export. The CDN bundle also exposes `uglifyjs.minify`.

parser

✓ const uglify = require('uglifyjs-lite'); const ast = uglify.parser.parse('code');

Access to the parser is available via `uglify.parser.parse()`. This is an internal API from UglifyJS v1.

Shows how to minify a simple function using the Node.js require() and the minify method.

const uglify = require('uglifyjs-lite'); const code = 'function add(a, b) { return a + b; }'; const result = uglify.minify(code); console.log(result); // 'function add(a,b){return a+b}' // For browser, use the CDN bundle: // <script src="https://kaizhu256.github.io/node-uglifyjs-lite/build..beta..travis-ci.org/app/assets.uglifyjs.rollup.js"></script> // then call window.uglifyjs.minify(code);

Known issues

deprecatedUglifyJS v1.3.5 is extremely outdated. Not maintained since 2013.

fix

Use a modern minifier like terser (recommended) or uglify-js (v3+).

affects: *

gotchaPackage only claims Linux/macOS support. May not work on Windows.

fix

Use a cross-platform minifier like terser.

affects: *

gotchaThe CDN link in the README points to a beta branch build; may be unstable or change without notice.

fix

Pin to a specific version or host your own copy.

affects: *

breakingNo ES6+ syntax support. Will throw errors on arrow functions, classes, etc.

fix

Use terser which supports modern JavaScript.

affects: *

gotchaPackage name 'uglifyjs-lite' is easily confused with 'uglify-js' (official) or 'uglifyjs' (other forks).

fix

Double-check you are using the intended package.

affects: *

Errors

Common errors & fixes

SyntaxError: Unexpected token: punc ())

Input code contains ES6+ syntax like arrow functions that UglifyJS v1 cannot parse.

fix

Use a modern minifier (e.g., terser) that supports ES6+.

Module not found: Can't resolve 'uglifyjs-lite'

Attempting to import the package in a bundler that expects ESM, but package only provides CJS.

fix

Use require('uglifyjs-lite') or configure bundler to handle CJS.
