Yesod is a high-performance web framework for Haskell focused on enabling productive development of type-safe, RESTful web applications. It leverages Haskell's strong static typing, compile-time safety checks, Template Haskell, and domain-specific quasiquoters to ensure high reliability and performance. 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).

Features

  • Compile-time type safety for routes, forms, and database access
  • RESTful architecture with strong typing of URLs and handlers
  • Fast, compiled code with constant-space memory consumption
  • Asynchronous I/O out of the box, powered by Haskell runtime
  • Template Haskell-based DSL for HTML templates (QuasiQuotes)
  • Comprehensive documentation, examples, and scaffolding via Stack templates
