golfy

library0.1.0jsnpmunverified

An aggressive JavaScript minifier specialized for code golf that prioritizes output length over stability, compatibility, and execution performance. Version 0.1.0 is a work-in-progress, experimental tool that performs transformations like replacing require() calls with inline expressions, stripping unnecessary variables, and other hacky optimizations. Compared to general-purpose minifiers (e.g., terser, uglify-js), golfy will break code in non-standard environments and is not suitable for production use. It is designed exclusively for competitive code golfing where byte count is the only metric that matters.

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.

golfy CLI

✓ golfy code.js

✗ node golfy code.js

golfy is primarily a CLI tool installed globally via npm. There is no programmatic API currently exposed.

stdin usage

✓ cat code.js | golfy

✗ golfy < code.js

Piping via cat or similar is the recommended way to process input from stdin.

Installation

✓ npm install -g golfy

✗ npm install golfy

Global installation is required for CLI usage; local install does not expose the binary.

Installs golfy globally and minifies a simple JavaScript expression, showing the shortened output.

npm install -g golfy echo 'const x = 1 + 2; console.log(x)' > input.js golfy input.js

Debug

Known issues

breakingOutput may produce code that only runs in specific JS engines (e.g., Node.js).

fix

Do not use golfy for production code. Only use for code golf where runtime is controlled.

affects: >=0.0.0

deprecatedThis project is highly experimental and may change without notice.

fix

Pin version if using in reproducible builds, but expect breaking changes.

affects: 0.1.0

gotchagolfy does not preserve side effects; it may remove code it deems unnecessary.

fix

Review output carefully. Test minified code to ensure intended behavior.

affects: >=0.0.0

gotchaStandard library functions may be inlined or replaced in ways that differ across Node versions.

fix

Use only well-known Node.js APIs and verify output on your target Node version.

affects: >=0.0.0

Errors

Common errors & fixes

golfy: command not found

global npm bin directory not in PATH

fix

Ensure npm global install location (e.g., /usr/local/bin) is in PATH, or use npx golfy.

SyntaxError: Unexpected token

Input contains unsupported modern JavaScript syntax

fix

Transpile code to ES5 or use a compatible version; golfy may not support all ES6+ features.

Error: Module not found

golfy tries to resolve require() calls but the module isn't available

fix

Ensure required modules are installed in the project or switch to Node.js built-ins.
