Hands-On Design Patterns and Best Practices with Julia

By: Tom Kwong

Overview of this book

Design patterns are fundamental techniques for developing reusable and maintainable code. They provide a set of proven solutions that allow developers to solve problems in software development quickly. This book will demonstrate how to leverage design patterns with real-world applications. Starting with an overview of design patterns and best practices in application design, you'll learn about some of the most fundamental Julia features such as modules, data types, functions/interfaces, and metaprogramming. You'll then get to grips with the modern Julia design patterns for building large-scale applications with a focus on performance, reusability, robustness, and maintainability. The book also covers anti-patterns and how to avoid common mistakes and pitfalls in development. You'll see how traditional object-oriented patterns can be implemented differently and more effectively in Julia. Finally, you'll explore various use cases and examples, such as how expert Julia developers use design patterns in their open source packages. By the end of this Julia programming book, you'll have learned methods to improve software design, extensibility, and reusability, and be able to use design patterns efficiently to overcome common challenges in software development.

Functional pipes pattern

Sometimes, when building an application, we face a large problem that requires complex calculations and data transformation. Using structured programming techniques, we can often break down the large problem into medium-sized problems and then break these down further into small-sized problems. When a problem is small enough, we can write functions to tackle each problem individually. 

Of course, these functions do not work in isolation it is more likely that the results of one function will feed into another function. In this section, we will explore the functional pipes pattern, which allows data to be passed seamlessly through a data pipeline. This is not uncommon in functional programming languages but is seen less in Julia. Nevertheless, we will take a look and see how it can be done.

First, we will go over a sample use case...
