An aggressive JavaScript minifier for code golf.

---

golfy is a program that converts the input code into code optimized for code golf.

Example

The following code

const fs = require('fs');
const input = fs.readFileSync('/dev/stdin');
console.log(input);

can be transformed as follows

console.log(require("fs").readFileSync(0))

Goals

The goals of this project are as follows:

• Shorter code over stability
• Optimization of the output over processing time
• The shortest possible expression, even if it's hacky

The things this project does not aim for:

• Ensuring compatibility across various runtime environments and backward compatibility
• Maintaining internal implementation consistency with the input code (as long as the same input produces the same output, it's fine)
• Execution performance (code length takes priority)

Usage

Warning

WIP project and is highly experimental and unstable.

npm install -g golfy
