F# 4.0 Design Patterns

By: Gene Belitski

Overview of this book

Following design patterns is a well-known approach to writing better programs that captures and reuses high-level abstractions that are common in many applications. This book will encourage you to develop an idiomatic F# coding skillset by fully embracing the functional-first F# paradigm. It will also help you harness this powerful instrument to write succinct, bug-free, and cross-platform code. F# 4.0 Design Patterns will start off by helping you develop a functional way of thinking. We will show you how beneficial the functional-first paradigm is and how to use it to get the optimum results. The book will help you acquire the practical knowledge of the main functional design patterns, the relationship of which with the traditional Gang of Four set is not straightforward. We will take you through pattern matching, immutable data types, and sequences in F#. We will also uncover advanced functional patterns, look at polymorphic functions, typical data crunching techniques, adjusting code through augmentation, and generalization. Lastly, we will take a look at the advanced techniques to equip you with everything you need to write flawless code.

Preface

Chapter 11. F# Expert Techniques

So far in the book, we've dealt mostly with customary F# facilities that constitute the core of successful F# idiomatic use in diverse application fields. The common sign of (almost) all of the related usage patterns is that they are straightforward and ordinary. Their mastery is a must for any intermediate level F# practitioner.

In this chapter, I'm going to step out of the regular space where expressions always yield results, calculations take place sequentially, and code must be first written in order to be later used. I will walk you through some of expert level F# techniques, the area of exciting usage patterns that is often considered overcomplicated and error-prone in nonfunctional paradigms.

In this chapter I will cover the following topics in the context of F# idiomatic use:

  • Type providers

  • Concurrent programming

  • Reactive programming

  • Metaprogramming

I will approach each of these subjects by giving a brief overview accompanied with a concise usage sample...
