Installation

npm install

npm test

Usage

CLI

Saves Abstract Syntax Tree (AST) to file:

./archaize.js -i someCode.js -o code-analysis --ast

Prints AST to standard output:

./archaize.js -i someCode.js --ast

Transpiles inputted JavaScript code (file) to another file:

./archaize -i someES6Code.js -o someES5Code.js --transpile

NPM package

const { transpile } = require('archaize-js/index.js');

// to avoid issues, it's recommended to firstly develop
// a read file function that returns the source code.

const transpiledCode = transpile(someExpression);
console.log(transpiledCode);
