The Snap Framework: A Web Toolkit for Haskell

Haskell is an advanced functional programming language. The product of more than 20 years of research, it enables rapid development of robust, concise, and fast software. Haskell supports integration with other languages and has loads of built-in concurrency, parallelism primitives, and rich libraries. With its state-of-the-art testing tools and an active community, Haskell makes it easier to produce flexible, maintainable, high-quality software. The most popular Haskell implementation is the Glasgow Haskell Compiler (GHC), a highperformance optimizing native-code compiler. Here, we look at Snap, a Web-development framework for Haskell. Snap combines many other Web-development environments' best features: writing Web code in an expressive highlevel language, a rapid development cycle, fast performance for native code, and easy deployment in production.
