Dive Into Design Patterns
https://refactoring.guru/design-patte...
Design patterns are typical solutions to commonly occurring problems in software design. You can’t just find a pattern and copy it into your program, the way you can with off-the-shelf functions or libraries. The pattern is not a specific piece of code, but a general concept for solving a particular problem. They are like pre-made blueprints that you can customize to solve a recurring design problem in your code.
The book Dive Into Design Patterns illustrates 22 classic design patterns and 8 design principles that these patterns are based on.
- Every chapter starts from a discussion of a real life software design problem which is then progressively solved by applying one of the patterns.
- Then goes a detailed review of the pattern’s structure and its variations, followed by a code example.
- Then the books shows various applications of the pattern and teaches how to implement the pattern step by step, even in an existing program.
- Each chapter concludes with a discussion of pros and cons of the pattern and its relations, similarities and differences with other patterns.

The most interesting and clear-to understand interpretation of design patterns. Beautiful pictures and grate examples. Thanks!

Reminds me "the Gang of Four", but found that book is good for the beginners, i like the examples, they hook me up, easy to remember and to think about. I've bought this book after reading and using online patterns registry on the site of the Author.

A great and easy-to-grasp introduction to some of the most used Design Patterns. Every pattern is presented in a very clear and step-by-step way. It's right to the point with no meaningless fluffing. It also contains real-life examples and analogies, so it's even easier to get some sense of the pattern and the principles behind it and develop some kind of perception of when and how to apply it. Really recommend it, if you want an awesome introduction to some of the most popular design patterns.

Among all the conceptual software/technical books I've read very few have a decent way of phrasing the knowledge they are trying to offer , even less if we consider how readable their visual format is .
Those who reach such requirements are considered an industry classics , some go even beyond becoming a class of their own where if a book falls too short in comparison then it's not worth it some of them are : Clean Code , Improving Design of existing code ,The Pragmatic Programmer: From Journeyman to Master , Code Complete , Gang of Four Design patterns , Computer Networking: A Top-Down Approach ...etc
This book was so well written and formatted it beaten the Gang of four on explaining design patterns , explained SOLID principles with extremely well defined examples something that the original Clean Architecture lacked , Summarized the spirit of OOP in a single chapter better than entire books on the subject ! .
It delivers what the book says and more in the most efficient possible way . This book cannot be described by any words other than Perfect .

Great book. Concise, but well-structured and very clear.

I really like the book. It is very helpful for me and my job as I am in this field (software) for many years(~15).
The Design Patterns are something I was not very familiar with. I already learned a lot from the book and I hope I will be able soon to get a new role in my career and maybe to teach other people about the patterns.
Everything is explained very well, the introductory part includes SOLID and fundamentals of OOP which is very good. I would do more examples if I could. What I would put here is a brief of symptoms of a bad design like rigidity, fragility, immobility and viscosity. But for me, it's exactly what I was looking for - design patterns with explanations and concrete examples in one place. And to be honest it was at the best price - personally I wouldn't do it for this amount.
Thank you again and congratulations for your work. Good luck!

I'm in love with this book. It's my favorite book about design patterns so far. I'm recommending it to everybody I can. The illustrations are great, I love the writing style, it's easy to read and comprehend for a non-native English speaker. The examples, real world analogies, relations between patterns, pseudocodes... everything is really, really great. Can't recommend it enough.

The only resource you'll ever need. Lives up to "Everything should be made as simple as possible, but no simpler."
These are the fundamentals that will outlive any framework, language, specific domain knowledge, and career. Would say it is worth it's weight in gold, but is only available in ebook form (please make a physical book).

A nice little book going over the basic design patterns.
My favourite parts are the "How/When to use this pattern" and "How this pattern relates to other patterns" at the end of each patterns explanation. This allows me to quickly see if the pattern I am thinking of is the right for the job and which patterns are maybe better suited for the current problem.

Surely, the best book to learn design patterns. Everything is comprehensive and detailed. Examples are fun and close to real world and they are solved very clearly.

Um dos livros mais simples e diretos sobre padrões de projetos que já li, os exemplos e analogias com o mundo real facilita bastante a compreensão dos padrões. Talvez o ponto fraco fique por conta dos exemplos de código que são escritos em pseudocódigo sempre focando apenas nas interfaces principais (o que não vem a ser um problema para padrões que são mais facilmente compreensíveis).
Certamente será o livro que irei recomendar para quem gostaria de apreender mais sobre padrões de projetos, SOLID e orientação a objetos em geral.

This book is very useful. While reading it,I immediately related to my own projects and how I could employ the design patterns described (especially the Strategy pattern and Chain of Responsibility). I am a young developer who have worked on big projects with national scale in Brazil, and the benefits of employing these design patterns in such large codebases are obvious.
The best qualities of this book are the illustrations and the example applications (this quality includes the UML diagrams and analogies), which make you quickly understand the concepts.
For the moment, I can't really think of a suggestion for improving. I would say giving ideas on small projects to practice each design pattern, but this book already describes a real-life use case and how to implement (refactor) on existing projects. That's very well enough!

I own three books on design patterns and this one is my favorite. Each design pattern is discussed in multiple steps:
- a problem to solve
- the solution
- a real-world analogy
- the structure of the pattern with a UML diagram
- pseudocode
- where to apply it
- tips on implementing it
- pros and cons
- relations to other patterns
There is also an overview of SOLID design principles, and for several of the pattern overviews it is described how the pattern relates to a specific SOLID principle.
One of the things I like most about the book are the illustrations. They are hilarious and encapsulate the concepts quite nicely.

Too beginner oriented. Not useful for senior developers.

Tasarım paternlerine hızlıca aşina olmak istiyorsanız bu kitap oldukça iyi, anlatım oldukça direkt ve sistematik. Güzel analojilerle desteklenmiş.
Kitap öncelikle OOP'nin temellerinden bahsedip devamında SOLID denilen, OOP'yi bu kadar iyi yapan ve daha anlaşılabilir, esnek ve sürdürülebilir kod yazılması amacıyla geliştirilmiş 5 tasarım prensibini anlatıyor. Bunu hemen devamında Creational, Structural ve Behavioral tasarım türlerinin içerdiği yaygın tasarım paternlerini anlatmaya başlıyor.
Her bir tasarım paterni için o tasarım paterninin çözmeye çalıştığı problemin ne olduğu, o problemin nasıl çözüleceği, çözümün UML diyagramıyla gösterilen örnek yapısı, paterne ilişkin örnek bir psödokod, paternin artıları eksileri ve son olarak da diğer paternlerle arasındaki benzerlikler farklılıklar ve ilişkiler açıklanıyor.
Yazılımla uğraşan bir tanıdığım mevcut durumumu belirtmek için analoji olarak programlamanın yazı yazmaya benzediğini söylemişti. Bir dilde kitap yazmak için önce o dilin alfabesini, sonra o dildeki kelimeleri, sonra bu kelimelerin birbirleriyle nasıl etkileşime geçtiğini yani o dilin gramerini, sonra belli cümle kalıplarını öğrenmemiz gerekir. Benzer bir durum programlamada da geçerli, bir programlama dilini öğrenirken önce o dili oluşturan temel yapıtaşları olan bir takım keywordleri ve bu keywordlerin anlamlarını, sentaksı, bir takım algoritmaları ve veri yapılarını öğreniriz. Ancak nasıl ki bazı cümle kalıplarına aşina olmak tek başına kitap yazmak için yeterli değilse benzer bir durum "düzgün" projeler yapmak isteyen bir programcı için de geçerli. Yazarın kitap yazması için kapsamlı bir analiz sürecinden geçmesi, hikayenin iskeletini çıkarması, bir takım stratejileri izlemesi gerekir. Programcının da yazacağı programın hiyerarşik yapısını, programda kullanılacak paternleri vs. önceden belirlemesi gerekir.
Bu analojiyi yapan tanıdığım benim kitap yazmaktan çok deneme yazıları yazma aşamasında olduğum gözlemini yapmıştı, başka insanların projelerini gördükçe bu gözlemin doğruluğunu teyit etmiş oldum. Bunun sonucunda da daha iyi bir "yazar" (programcı) olmak için bu tasarım paternlerini öğrenme kararı aldım ve bu kitaba başladım. Kitabı okurken karşılaştığım bu paternlerin bir kısmını zaten halihazırda bazı yerlerde kullandığımı gözlemledim, bu paternlerin diğer bir kısmı ise üzerinde düşündüğüm ama çözümünü araştırmayı ertelediğim durumların çözümünü veriyordu, bir başka kısmı ise daha önce üzerinde düşünmediğim problemleri ve çözümlerini çözüyordu. Haliyle bu paternleri gözlemlemek de benim için eğitici oldu. Bunların bir kısmını, isimleri ile birlikte unuturum ama kavramsal olarak kafamda yerlerini edindiler.
Tasarım paternlerini öğrenmeyi programlama ve proje geliştirme ile ilgilenecek arkadaşlara da tavsiye ederim ve bu kitap iyi bir başlangıç noktası gibi duruyor.

I found this book at the right time. Recently I had the idea for an app and found a world of pain around DDD, DI, design patterns, etc. I was really good information and getting snippets from YouTube and the wider web, but this book stood out, as it was both technical and incredibly easy to read. What I really like about this ebook can be summarised as follows.
1. Epub: This format allows me to use my desktop ereader (Thorium) and get a great reading experience. The book has a very professional feel, which shows throughout. Since purchasing the book, I find I have it open on my desktop for quick reference purposes.
2. All in One Place: Having all design patterns in one place provides a really good and quick reference. As I don’t know which pattern may apply, I have find myself re-reading several patterns to understand which, if any, might apply to a particular situation. The internet has lots of great resources, but few pull all designs together in one coherent and yet compact resource. This book nails it for that and includes a summary of each design pattern for v. quick reference. No more saving web page favourites; I bookmark the ebook and I'm away.
3. Stories: This is a really big one. Providing a fictional but interesting story with pictures and UML for each pattern has been a huge thing for my design patterns education. Many internet examples have UML, but their technical language leave me cold and uncertain on how I to apply them. The slower reveal of the stories in this book have made them stick with me and I find myself thinking several days later, ah! I can rewrite this and use the strategy pattern. I've also read part of the Head First design patterns book and it has a similar style.
4. SOLID: Including this with design patterns reinforces the message around clean coding. What's more, I think this book has the best write-up of SOLID that I've read so far.

Книга отменная, все кратко, емко, наглядно и по делу; лучшая, наверное, на сегодняшний момент из всех, что я видел по данной тематике; можно смело рекомендовать как новичкам, так и специалистам;
Написано доходчиво, последовательно, упомянуты все важные темы, изложить постарались кратко и понятно (в HeadFirst примеры разжеваны сильнее, но тут они короче и нагляднее); можно рекомендовать прочесть даже до HeadFirst-овской книжки;
Если кратко сравнить с другими (возьму популярные):
- GoF - скорее каталог паттернов, эдакий справочник для программистов, которые уже с такими проблемами сталкивались и будут использовать книжку, чтобы вспомнить, какое можно взять решение для той или иной общей проблемы; новички из нее много не вынесут (т.к. паттерны - решения общих проблем, то они с такими проблемами даже не сталкивались, чтобы оценить элегантные способы их решения)
- Head First, Паттерны проектирования - учебник, специфика изложения - именно под обучение, чтобы лучше запомнить мысль, одно и то же рассказывается несколько раз, просто разными словами;
А здесь золотая середина - можно читать по порядку, либо пользоваться как справочником;
У книги замечательная методическая ценность, на наглядных примерах "на пальцах" гораздо проще объяснять паттерны (в той же GoF примеры более специфичны, их представить новичку будет сложнее; к примеру - Visitor для разбора синтаксического дерева, фасад - тоже что-то про компиляцию, либо State с примером про TCP-коннекты);
Особенно хорошо, что есть разделы "зачем знать паттерны", принципы SOLID и подобные вещи, неотъемлимо относящиеся к паттернам;
Псевдокод - хорошее решение, т.к. реализация паттернов на конкретных языках программирования будет различной, специфической для этого языка и будет отвлекать от сути;

This book definitely makes its way to the top 5 books a Software Engineering student should read. It's a must-have. My teacher recommended it to learn about design patterns and how to use them in projects. Thing is, there are many articles online explaining Design Patterns, but I just couldn't grasp the concepts with those. I needed an alternative, another read.
I found myself going to class with only this book and asking questions about specific cases I thought of as the class went on. I used it to study for my final exam. I passed. But, the class was pretty much based on this book, so I figured I should really use it and put it to the test. I knew the contents would be useful for every project. After all, Design Patterns and SOLID principles are best practices, right? I had to make sure that this book helped in a different way that just searching on the web.
I was astonished after just a week of using it for a real project. It's not just the patterns and the principles, it's the way they are explained and organized. It's having an actual guide that lets you know if using a pattern makes sense for a given case. It's making sure that every component does its job as it's supposed to and knowing why. It's understanding what's going on in your code. All of that, and maybe even more, is inside this book.
After just over a month, I was able to remove duplicated code, better organize my classes and the interactions between them, and improve the abstraction and overall performance of my app. I can't put into words how much I have improved as a developer thanks to this book. I realized that there is so much more to learn. I now know that this book, in the hands of young developers, can change the learning experience of software development for the better.

Книга отличная. Написано максимально доступно, без излишней терминологии и воды. Примеры достаточно понятные, из жизни.
Начал читать еще когда был только сайт, но захотел поддержать автора :)
Больше всего нравятся иллюстрации паттернов - иконки, по которым быстро запоминается назначение и разделы с практическими применениями и связями паттернов между собой.
Хотелось бы добавить еще паттернов. Я еще очень давно писал про "репозиторий". Достаточно удобный и популярный. Еще можно "единицу работы" добавить.
Вообще хотелось бы больше более специфических паттернов.
Общие можно где угодно найти, а вот более сложные нуждаются в простом объяснении, которого как раз в интернете не найдёшь.
Еще одно пожелание, как программиста на JS - возможность добавить где-то примеры для фронт-енд.
Сейчас много программистов работают на JS, даже не зная, как использовать тот или иной паттерн на практике. Или не зная, что задача уже решалась сотни раз.
P.S. Погружением я бы это не назвал. Так, мелководье :)

The project in general and the book in particular are making the great impression. It seems there are a lot of books on a subject, but yours is really the best and it's quite funny. Wonderful illustrations, they are amusing and helpful for memorizing.
I've started reading it just after buying. I've learned already how to use couple of described patterns in practice.
The book can be improved by publishing it in print, it would be convinient to give it as a present for example.
Проект в целом, и книга в частности, производят отличное впечатление. Казалось бы книг написано на эту тему довольно много, но у вас все "по полочкам" и довольно весело)
Замечательные иллюстрации, и забавно и запоминать помогают.
Начал читать сразу после покупки, пару - тройку из описанных паттернов уже научился довольно уверенно использовать на практике.
Книгу можно улучшить, издав ее на бумаге, это было бы удобно например для подарка.

I loved the book on design patterns.
Every pattern is described in such rich and comprehensive detail.
Not to mention the beautiful illustrations and UML diagrams alongside.
Also appreciate the discussion on SOLID and OOP basics.
I would have loved if it had Python real-world code though, since Python is my primary language.
But I guess, I can translate them from Java as an exercise! :)
Overall, it seems like a worthwhile purchase! No regrets!
A suggestion to the author:
The 'Related patterns' section at the end of every pattern is very helpful. Really appreciate the effort.
But I felt that it would have been better if all such relationships were mentioned after all the patterns had been introduced already, since the reader might not be acquainted with all the other patterns.
This would also help prevent the redundancy introduced by mentioning the relationships twice for every pair of patterns.

But I felt that it would have been better if all such relationships were mentioned after all the patterns had been introduced already, since the reader might not be acquainted with all the other patterns.
This would also help prevent the redundancy introduced by mentioning the relationships twice for every pair of patterns.

An excellent book! A worthy successor to the GOF. This updated take on Design Patterns is very refreshing. For a computer science book it is quite readable, much more so than the original. The real life examples provided in the book are very easy to follow. The code examples are very also easy to follow and provided in several different languages (C#, Java, PHP, Python,Ruby,Swift, and TypeScript). There are plenty of UML diagrams as well, clearly showing what is going on. He also does a good job of relating the various patterns and their ideal use cases.
Alexander broke from the original book and removed the text editor example and replaced it with an introduction to OOP. It includes a very concise and clear section on the SOLID principles with some very good examples.
Overall, I think this is probably a more approachable book for beginners than the original GOF. I highly recommned it!

Este libro supone un acercamiento a los patrones de diseño clásicos muy accesible. El lenguaje es sencillo y ameno (Sobre todo teniendo en cuenta que está en inglés).
Se explican todos y cada uno de los patrones de una forma muy clara sin exceso de tecnicismos. Y los que usa (conceptos de OOP y Digramas UML). Vienen explicados al principio del libro para poder repasarlos en cualquier momento.
Las abundantes ilustraciones te ayudan en la fijación de los conceptos. Y el pseudocódigo que viene en el libro te ayuda a clarificar como sería la implementación de un patrón. Con el libro, también vienen ejemplos de implementación en lenguajes concretos. Pero para mí, con el pseudocódigo ha sido suficiente.
En definitiva. Un libro tremendamente recomendado para todos aquellos interesados en aprender sobre patrones de diseño.

I have ~10 years of experience in software engineering, but I had always been in the mindset of "patterns should come naturally when trying to figure out a solution rather than trying to use them either way". I'm pretty happy that I decided to read it, because now I have a more in-depth idea of the basic patterns and can apply them much better. There's no need to reinvent design patterns when they are perfectly explained and documented in your book.
I reckon it's a book that I will read more than once, as some of the patterns might need more than one read to really understand all their details.
This book provides a very good and concise explanation of the most used patterns, where to apply them and how to get started with them. If anyone asked me for a book to get started with design patterns I would definitely recommend it.

Книга превзошла ожидания - помимо самого каталога паттернов, там есть хорошее введение тему ООП и SOLID, а также, разбор диаграмм классов. С первых страниц понимаешь, что книга сделана с умом и для людей, со вниманием к мелочам.
Будет ли книга полезна опытному разработчику? Да, это отличный справочник по паттернам проектирования. Примеры на псевдокоде и реализации на конкретных ЯП позволят максимально быстро разобраться.
Будет ли книга понятна новичку? Да, всё описано на примерах "из жизни", текст легко воспринимается и сопровождается прекрасными иллюстрациями.
Минусы:
Не советую читать перед сном, потому что в какой-то момент настолько захочется реализовать один из паттернов, что не сможешь уснуть! :D

September 1, 2019I rarely buy e-books but this was a great purchase. I read through every summary/intro but I have only skimmed the more detailed implementation and example code. I have been doing moderately in-depth coding projects in school for Creative Technologies but I only heard about design patterns a few days before I bought this book. I think it was a perfect way to get an idea of what I have been missing out on and now I know some better ways to think about coding. All of the examples were quite good and the arc of teaching about each method was incredibly consistent with starting place and pace throughout each chapter. This is in contrast to some Swift and iOS development books that I read recently that were really not good.

Dive into design patterns is one of the best books about design patterns,
If I may say the best one in the whole market.
The tips in your book have helped me become more productive! Before this book,
I was wasting so much time figuring out how to write solid code, and apply patterns on my projects.
But the moment I discovered this book, instantly patterns looks simple and understandable:
The illustrations, comments and explanations were all perfects,... etc.
The most enjoyable part for me was the real-world examples section.
Thank you for your instructions and for the Dive into design patterns book.
many libraries and frameworks internals start to become familiar to me.
