Key benefits

Comprehensive guide for establishing a strong foundation in Haskell and developing pragmatic code

Create a full fledged web application using Haskell

Work with Lens, Haskell Extensions, and write code for concurrent and distributed applications

Description

Haskell is a purely functional language that has the great ability to develop large and difficult, but easily maintainable software. Haskell Cookbook provides recipes that start by illustrating the principles of functional programming in Haskell, and then gradually build up your expertise in creating industrial-strength programs to accomplish any goal. The book covers topics such as Functors, Applicatives, Monads, and Transformers. You will learn various ways to handle state in your application and explore advanced topics such as Generalized Algebraic Data Types, higher kind types, existential types, and type families. The book will discuss the association of lenses with type classes such as Functor, Foldable, and Traversable to help you manage deep data structures. With the help of the wide selection of examples in this book, you will be able to upgrade your Haskell programming skills and develop scalable software idiomatically.

What you will learn

* Use functional data structures and algorithms to solve problems

* Understand the intricacies of the type system

* Create a simple parser for integer expressions with additions

* Build high-performance web services with Haskell

* Master mechanisms for concurrency and parallelism in Haskell

* Perform parsing and handle scarce resources such as filesystem handles

* Organize your programs by creating your own types and type classes

I've been learning Haskell using a chaotic combination of websites, library books, and "Hey, how do I do this?" email messages. This process has not been easy, especially after I got bogged down trying to figure out whether to use the Glasgow Haskell Compiler (and GHCi), or Cabal, or Stack, or learn all three, and maybe throw in Visual Studio, as well. As a writer and book reviewer, I often review software books aimed at newcomers to a particular programming language. So I'm grateful that Packt Publications gave me access to a review copy of its Haskell Cookbook, which was published five years ago. The book has brought me some solid how-to information and a straightforward strategy for learning Haskell. And I am pleased to recommend it to others learning Haskell. With a focus on using Stack, the book takes a very practical, nicely illustrated, three-step approach as it introduces and explains new topics and provides coding examples. The steps are: getting ready; how to do it; and how it works. The book is well-written, and its chapter organization has helped me get a better focus on my efforts. Note: It is very important to download the code samples associated with the Haskell Cookbook. I have encountered a small number of code examples in the book's text that either have a typo or are out of date because of Haskell changes. In those cases so far, when I've typed in some code from the book and it has not compiled, the downloaded code-example files have worked fine. Because of the book's current age, I can't give it a five-star rating. But for me at least, I'm pleased to give it four stars, and I'd add another half star if I could.

This is a great book to sharpen your understanding of Haskell concepts. The book will not teach you concepts like State Monad or Reader Monad, but is good at getting better understanding by trying out real world examples ( recipes). My understanding of Monad Trasformers definitely improved. This book is best to study Haskell along with other books like 'Programming in Haskell ' by Graham Hutton. Another plus point is that the examples are complete with stack build tool. Many Haskell books on fundamentals give toy examples to explain but you may not have much clue when and where to use them. Examples for data base connection in this book are solid.
