What is the Snap Framework?

Snap is a simple web development framework for unix systems, written in the Haskell programming language.

Snap aims to be the de facto web toolkit for Haskell, on the basis of:

  • High performance
  • High design standards
  • Simplicity and ease of use, even for Haskell beginners
  • Excellent documentation
  • Robustness and high test coverage

What is the project's status?

Snap launched to the public in May, 2010. The core framework contains:

  • A fast HTTP server library.
  • A sensible and clean monad for web programming.
  • An HTML-based templating system for generating pages that allows you to bind Haskell functionality to tags without getting PHP-style tag soup all over your pants
  • A high-level system called Snaplets for building modular web applications.
  • Built-in snaplets for templating, session management, and authentication.

Snap runs on *nix platforms; it has been tested on Linux and Mac OSX Snow Leopard. Windows support was added more recently, but it not as well-tested.
