Running the Demo

Ruby2JS provides a web-based demo tool you can use to try out Ruby code and see how it converts to JavaScript. (This is same tool used for the online demo).

Usage

The following commands will start a local demo server:

git clone https://github.com/ruby2js/ruby2js.git
cd ruby2js
bundle install
ruby demo/app.rb

Then open http://localhost:4567 in your browser.

The demo provides a live editing experience - JavaScript output updates as you type Ruby code. Dropdowns are provided to change the ECMAScript level, filters, and options. A checkbox is provided to show the Abstract Syntax Tree (AST) produced.
