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
