An asset pipeline wrapper for the typescript language

branch: master

TypeScript for Rails Build Status

Looking for a new maintainer: Since I am no longer working with TS in my day to day life, and there are some major changes coming up, I'm looking for someone who wants to take over development of this gem

This is a wrapper for the TypeScript JavaScript superset language by Microsoft.

It enables you to use the .ts extension in the Asset Pipeline and also in ActionView Templates.

This gem uses the typescript-node-ruby library by KAWACHI Takashi for the typescript parsing with node js.

The credit for the overall structure and the tests goes to the people that wrote the coffee-rails Gem, since I shamelessly copy&pasted some of their code.


The current version requires that node.js is installed on the system.

The requirement for node is tested upon starting the application. If the node command is not available you get the following error message:

typescript-node requires node command, but it's not found. Please install it. Set TS_NODE environmental variable If you want to use node command in non-standard path.


Add this line to your application's Gemfile:

gem 'typescript-rails'

And then execute:

$ bundle


Just add a .js.ts file in your app/assets/javascripts directory and include it just like you are used to do.
