Developing Web Applications with Haskell and Yesod

Request Review copy

Sebastopol, CADeveloping Web Applications with Haskell and Yesod (O'Reilly Media, $34.99 USD) introduces a potent language/framework combination that supports high-performing applications that are modular, type-safe, and concise.

"This fast-moving guide was written for programmers with existing web experience, who are interested in taking the plunge into functional programming," explains author Michael Snoyman (@snoyberg). "Some familiarity with Haskell is required, but we provide an introduction to the more complex topics. Users will start off by learning the details of how to use Yesod at a high level, from RESTful routing to Shakespearean templates and data persistence."

By the time you finish this book, you'll create a production-quality web application with Yesod's ready-to-use scaffolding. You'll 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 Yesod's foundation datatype and Web Application Interface (WAI)
  • Use Shakespearean template languages for HTML, CSS, and Javascript output
  • Produce cleaner, more modular code by learning how Yesod monads interact
  • Implement the yesod-form declarative API to build forms on top of widgets
  • Learn how Yesod and Haskell store session data and handle persistence
  • Use techniques to serve an HTML page and a machine-friendly JSON page from the same URL
  • Create reusable components for several applications with Yesod subsites

"Yesod 1.0 was just released," Snoyman smiles. "As such, we're announcing to the world that Yesod is stable, and ready for general consumption. Now's a great time to get into Yesod."
