decaffeinate is a CLI tool that converts CoffeeScript source code into modern JavaScript. It is a mature, production-tested converter used to migrate large codebases away from CoffeeScript.

Use cases

  • convert coffeescript to javascript
  • migrate codebase off coffeescript
  • rewrite .coffee files as modern js
  • bulk convert a project from coffeescript
  • modernize legacy coffeescript code

When to choose

  • you need to migrate CoffeeScript projects to JavaScript
  • you want a battle-tested converter used on millions of lines of production code
  • you want a CLI plus an online repl for quick conversions

When to avoid

  • you need live transpilation of CoffeeScript at runtime rather than one-time conversion
  • your project is not CoffeeScript
  • you expect active feature development - the project is complete and in maintenance
