This fast-moving guide introduces web application development with Haskell and Yesod, a potent language/framework combination that supports high-performing applications that are modular, type-safe, and concise. Fully updated for Yesod 1.4, this second edition shows you how Yesod handles widgets, forms, persistence, and RESTful content. Author Michael Snoyman also introduces various Haskell tools to supplement your basic knowledge of the language.By the time you finish this book, youll create a production-quality web application with Yesods ready-to-use scaffolding. Youll also examine several real-world examples, including a blog, a wiki, a JSON web service, and a Sphinx search server.Build a simple application to learn Yesods foundation datatype and Web Application Interface (WAI)Output HTML, CSS, and Javascript with Shakespearean template languagesGet an indepth look at Yesods core monads for producing cleaner, more modular codeProbe Yesods internal workings: learn the request handling process for a typical applicationBuild forms on top of widgets by implementing the yesod-form declarative APILearn how Yesod and Haskell handle persistence and session dataServe an HTML page and a machine-friendly JSON page from the same URL
