miku :: MikuMonad -> Application
This template project shows how to incorporate sandboxing, auto-reloading and other cool stuff.

- It's recommended to use your own html combinator / template engine. Try DIY with, e.g. moe.
- Example view using custom html combinator (moe in this case)
- When inspecting the request, use
askdefined inReaderTmonad to get theHack2.Environment, then use helper method defined inHack2.Contrib.Requestto query it. Responseis inStateT,htmlandtextare simply helper methods that update the state, i.e. setting the response body, content-type, etc.- You do need to understand monad transformers to reach the full power of
miku.
