Typescript-AMD

While there are some existing efforts to bring typescript to the asset pipeline (and ruby), I didn't find them acceptable for the following reasons:

• existing solutions compile to commonJS modules, which are not terribly useful for the browser (requirejs is an AMD implementation)

• Typescript compilation through tsc is crazy slow (2s for a single trivial file on my machine). This is because they are massively optimizing for interactive compilation

• Typescript as a language has a bit of a wart -- the /// <reference src='path' /> comments. The typescript team is exploring alternative syntaxes, but to get around the clunkyness, all reference files (.d.ts) in a configured directory (app/assets/references by default) will get included into every file. This is according to my opinion, which is that those comments should only ever be used for declares and possibly interfaces, nothing else.

Installation

Because it uses an interactive compiler, node.js is required to be installed and accessible on the PATH. It uses the typescript.api node module, which provides the typescript compiler as a service.

Add this line to your application's Gemfile:

gem 'typescript-amd-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install typescript-amd-rails
