Description

Hands-On Dependency Injection in Go takes you on a journey, teaching you about refactoring existing code to adopt dependency injection (DI) using various methods available in Go. Of the six methods introduced in this book, some are conventional, such as constructor or method injection, and some unconventional, such as just-in-time or config injection. Each method is explained in detail, focusing on their strengths and weaknesses, and is followed with a step-by-step example of how to apply it. With plenty of examples, you will learn how to leverage DI to transform code into something simple and flexible. You will also discover how to generate and leverage the dependency graph to spot and eliminate issues. Throughout the book, you will learn to leverage DI in combination with test stubs and mocks to test otherwise tricky or impossible scenarios. Hands-On Dependency Injection in Go takes a pragmatic approach and focuses heavily on the code, user experience, and how to achieve long-term benefits through incremental changes. By the end of this book, you will have produced clean code that’s easy to test.

What happens if an Early Access Course is cancelled?

Projects are rarely cancelled, but sometimes it's unavoidable. If an Early Access course is cancelled or excessively delayed, you can exchange your purchase for another course. For further details, please contact us here.

Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.

I have never used Go professionally but that din't stop me from enjoying this book. It goes over so many topics that everyone dealing with software need to know. I especially enjoyed how it tied DI to the SOLID principle and encouraged everyone to think about when DI might not be the right choice. A very balanced account on how DI can make your life easier with lots of examples that are easy to grasp but with enough details that can be used in everyday problems.

This is an excellent book for both beginners and experts in Go and is especially useful for folks who build complex systems in this language.Go is a relatively new language and if you're anything like me, coming from older, object-oriented languages, it may be easy for us starting exporting interfaces and organise packages in the similar manner to what we used to do in other languages. This would result in complex dependencies, tightly coupled packages and just more problems as your program grows. I wish I had this book when I started with Go couple of years ago.Besides going in depth through dependency injection, this book also goes through SOLID principles and explains how they related to DI and Golang (in Chapter 2). All-in-all, this is a great read!

This book is very helpful and has covered many ways on how to work your way and develop good code in Golang. As a developer coming from Java world, it is quite common to make mistakes in writing it the Java way and having conventions that I am already used to. This books has helped me basically get more comfortable writing code the Golang way. Dependency injection definitely needs to be part of the development and knowing how to do it the right way in Golang is really important. I recommend this book for everyone who would like to explore the possibilities of dependency injection in Golang.

This is the kind of book I wish I'd had when I was starting out with Go. It is one thing to be familiar with best practices in software development in general, but quite another to be able to apply it with a new programming language. As the author explains, naively bringing patterns from other languages isn't going to work with Go - it will lead to frustration and subpar results.Although the book's main focus is Dependency Injection (DI), many other design principles are covered along the way, and reading this made me realise how fundamental DI is to writing good Go code. This is a very practical book, and it contains a wealth of code and examples that can actually be used day-to-day.One of the things I appreciated most about this book is how the author balances both the advantages and disadvantages of the techniques described. No solution is perfect, and it is important to know the potential problems and pitfalls you might face before implementing a new idea.The benefits claimed by reading this book should appeal to every Go professional: more readable, maintainable and testable code. Those reading your code in future - your colleagues, or your future self - will thank you!

I have been writing golang for a year, but haven't put much serious thoughts in how to write my code better. By reading the first few chapters of this book, I have already gained some useful insights. The book showed useful examples of how to improve the structure of code with dependency injection. I highly recommend this book for anyone interested in improving his craft.
