summary Refactoring Improving the Design of Existing Code

As the application of object technology particularly the Java programming language has become commonplace a new problem has emerged to confront the software development community Significant numbers of poorly designed programs have been created by less experienced developers resulting in applications that are inefficient and hard to maintain and extend Increasingly software. While this book is of a reference book than a book to read through a memorise and I intend to use it as such in the future this book is well worth having for software engineers looking to improve their practices Even if you don t subscribe to Martin Fowler s lots of small methods and classes style of programming and I admit it takes some getting used to the techniues in this book are still useful and applicable to any software project The book consists mainly of a catalog of refactorings These can be thought of as a toolbox for a programmer looking to clean up their code and improve the code s design with each refactoring giving a description of how to apply it and a rationale as to when you may wish to The tail end of the book consists of some large scale refactorings which are much less mechanical and hazy due to their much larger scope and some chapters written by proponents of refactoring including the renowned Kent Beck of XP and Smalltalk fameIn a manner very similar to the GoF Design Patterns book the refactorings are grouped into sections of similar functionality and most of the refactorings have an inverse refactoring extract method has an inverse of inline method there is both push up hierarchy and push down hierarchy for fields and methods and so on which are useful in different circumstances This aids the book as a reference book and many refactorings also refer to other refactorings within the book as potential followups or re use them as smaller sub sets of a larger refactoring such as extract superclass involving pushing methods and fields up the class hierarchyOverall the book is worth a read through to familiarise yourself with the content and keeping close at hand for if you need to remember the details of a specific refactoring The writing is clear and concise and the refactorings are mostly self contained so you don t need to go searching over many sections to find all the details A solid although not exactly thrilling book and definitely a foundation for programmers looking to improve their coding skills

Refactoring Improving the Design of Existing Code

System professionals are discovering just how difficult it is to work with these inherited non optimal applications For several years expert level object programmers have employed a growing collection of techniues to improve the structural integrity and performance of such existing software programs Referred to as refactoring these practices have remained in the domain of. The second edition of the classic Refactoring book by Martin Fowler is than just an update It switched from Java to JavaScript for most of the examples what lead to many renames of refactorings for example extract function instead of extract method Most of the classical refactorings are still there and it had space for new ones like Split Phase one practice I found by myself and now can refer to using a name This tradition of giving names to practices around refactoring is continued and will be useful for the years to come The most significant change beside the programming language is that Fowler uses and smaller steps to explain the refactoring This makes it much easier to apply a refactoring to your own code and may change the perception of small steps being slow The opposite is most often the case smaller steps result in lot less fixing and debugging and that speeds up refactorings significantly I got the print edition and I m disappointed with the thin paper they used The back of the page can be seen and the headings use a rather bad combination of black and red that looks like a defect than an intended design decision

Experts because no attempt has been made to transcribe the lore into a form that all developers could use until now In Refactoring Improving the Design of Existing Software renowned object technology mentor Martin Fowler breaks new ground demystifying these master practices and demonstrating how software practitioners can realize the significant benefits of this new process. This book is a must read for every software developer I would personally recommend it to my team membersI totally agree with Martin and his vision that the changes should be incremental I think everyone that tried a complete rewrite at some point failed or at least achieved unsatisfactory results Maybe they didn t completed in time or didn t achieve the expected resultsThe most important aspect that is emphasized in the book is that you should apply refactoring when you need to not just going blindly and refactoring everything What we have in our team as a good rule of thumb is basically what is promoted in this book once you start working on a new feature or fixing a bug and you see any issues with the code your started working on you start refactoring and then implement the feature or fix the bug In some cases you can fix the bug and refactor later but the important thing is doing only ONE thing a timeI liked that Martin says that these refactoring are not a silver bullet and gives them in pairs eg remove class with extract class I think he makes the readers think if they actually need to perform any refactorings at all and that they all depend on the contextRemember that refactoring is a process not an event

    Overall I was disappointed in this book Modern tools and IDE's have removed nearly all of the pain points that are laid out in this book which made reading annoying and tiresome I skipped the Mechanics section of every single refactor because they are just not relevant in 2016 Your compiler and IDE will tell you every t

    Refactoring is the process of rewriting software without changing the way it functions in order to improve its readability testability or maintanability A book has been written on the subject by Martin Fowler Some of the chapters were written by other people“Refactoring Improving the Design of Existing Code” is focused on OO programming lots of Java examples and Agile practices It is setup as a catalog of refactoring techni

    If you are interested in improving and maintaining the uality of your code this book should be on your reading list It is not the kind of book you read once and forget about it When you are doing refactoring it’s always recommended to come back and check the categories explained in it What I really enjoyed is that it confirmed some of the ideas I already had about software development On the first hand you should have a robust t

    This book is not just for refactoring it's for understanding how professional are thinking about their code You can use these methods even in writing the first line of your code This is one of the books that every developer should read to transform his knowledge to be in readable and flexible code

    Refactoring is definitely an educational read for any programmer It covers many areas of refactoring from why we need it to how we should do it and get it done The only regret that I have right now is reading the first edition of this book 20 years old while there was a second edition which was published 2 years ago When I read the change l

    You hear something about refactoring and you want to see what it is ?You want to make your code better but don't know how to do it ?If your answer is yes then this book is for youMartin Fowlers 'Refactoring' is in my opinion the best book about this subjectAuthor describes many refactoring techniues and explain how and when to use themEach techniue has it's own example write in javascript code is very easy to

    Biggest takeaway is to take really small steps when refactoring which the book demonstrated a lot with detailed examples A lot of times I felt uncomfortable during refactoring but now I know it's because that I cut corners and didn't take small enough stepsThe book also refactors to patterns a lot which I found helpful reading immediately after the design pattern book
