Haskell 웹프레임워크 Yesod 퀵 스타트 가이드
Yesod 웹 프레임워크의 주요 특징은 다음과 같다.
- safety & security guaranteed at compile time
- developer productivity: tools for all your basic web development needs
- raw performance
- fast, compiled code
- techniques for constant-space memory consumption
- asynchronous IO
- this is built in to the Haskell programming language (like Erlang)
