Snaplet Coffee

Snaplet Coffee is a snaplet for the Haskell web framework Snap. It will let you easily use CoffeeScript in your Snap web applications.

This snaplet is based off of the Snaplet-Fay And I've made it so that they basically work the same way.

Example Usage

Practically copied from Snaplet-Fay

Site.hs:

import Snap.Snaplet.Coffee

routes = [..., ("/coffee", with coffee coffeeServe)]

app :: SnapletInit App App
app = makeSnaplet "app" "A snaplet example application." Nothing $ do
  coffee' <- nestSnaplet "coffee" coffee initCoffee
  return $ App { _coffee = coffee' }

Application.hs:

import Snap.Snaplet.Coffee

data App = App { _coffee :: Snaplet CoffeeScript }

makeLenses ''App

Run your application now.

A snaplet config file will be generated at snaplets/coffee/devel.cfg the first time your application initializes the snaplet. The defaults are the recommended ones for development.

Place your CoffeeScript .coffee files in snaplets/coffee/coffee. Note that a default devel.cfg will not be created if you have already created the coffee directory. If this happens to you, move snaplets/coffee, start your application, and then move the files back into snaplets/coffee.

Any requests to the specified directory (in this case /coffee/) will compile the appropriate CoffeeScript file and serve it.
