Haste is a dialect of the Haskell programming language geared towards web applications.
Ranked in these QuestionsQuestion Ranking
Pro Automatic, type safe program slicing
Haste lets you write client and server as a single program, automatically generating code for the server as well as the client, giving you full type safety even across the Internet.
Pro Almost full power of Haskell
Haste supports the Haskell 2010 standard except for Template Haskell as well as most GHC extensions.
Pro Client and Server as the same application
Haste was designed to allow both the client and server to be written as parts of the same, type-safe application. This is in stark contrast to most other options, where the client and server are considered two separate entities, resulting in extra manual validation code and more chances for type errors.
Pro Generates small, reasonably performant code
Con Lacks some minor Haskell functionality
Lacks support for Template Haskell.
