js2coffee is a JavaScript-to-CoffeeScript compiler available as a CLI tool and a Node.js/browser library. It parses JavaScript with Esprima and emits CoffeeScript code, warnings, and source maps.
Use cases
- convert javascript files to coffeescript
- migrate a legacy js codebase to coffeescript
- compile javascript to coffeescript from the command line
- use a javascript-to-coffeescript compiler in a node script
- convert js snippets to coffeescript in the browser
When to choose
- you need to translate existing JavaScript source into CoffeeScript
- you want both a CLI and a programmable API with warnings and source maps
When to avoid
- you want to convert CoffeeScript to JavaScript (use the CoffeeScript compiler instead)
- you need a general-purpose JavaScript transpiler like Babel
- the project's maintenance pace or CoffeeScript's declining usage is a concern
