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.

I received a review copy of the book and I enjoyed it thoroughly. The author does a great job covering the Go language from the basics all the way to advanced concepts. In particularly, I appreciated the chapter on templates (coming in Go 1.18). It is one of the features I personally wait for. The author's style is very engaging. He explains the concepts concisely, yet in detail and demonstrates with code samples. I highly recommend it to beginners as well as seasoned Go developers.

Mastering Go is a book that I picked up recently, in order to develop better APIs than I was able to with Node.js. Mastering Go is designed as a book that teaches Go holistically, first teaching the fundamentals of the language, then teaching common software engineering concepts as they relate to Go, such as multithreading, testing, profiling, and writing APIs. I really liked the exercises and additional resources that the book provided at the end of each chapter, because they helped me go from writing the bare-minimum amount of Go code to cover each concept, to writingmany programs with Go to gain a deeper understanding of the language.With this book, I have learned quite a bit about Go. I have learned how to make REST APIs. With some additional study, I've even learned how to connect with databases in order to have a persistent data store linked to my API. Overall, learning Go with Mastering Go has been a pleasure, because it has taught me a new programming language, allowed me to learn exactly what I intended regarding REST APIs, and now I have a new tool in my tool belt. There's also a lot about other networking services in the book, including writing TCP and UDP clients, and working with gRPC. I believe that this information is going to come in handy for me down the line.I plan on using Go to create my own full-stack video streaming site for software demos, and learning the language via Mastering Go is going to make it fairly simple to create the REST API side of this app. I feel comfortable using Go for production-grade applications, and I hope to use it in my projects in the future.

Go is a beautiful programming language and this book makes the learning of Go easier.Have in mind that you still need to write your own programs to learn Go. No book can replace practice.

The book feels more like a journal than a tech manual. the golang use case and it's origin story is compelling.

Mastering Go is truly a great resource for learning and mastering the Go programming language. I don't use Go professionally but have always wanted to really learn it well to no avail. I decided to finally sit down and spend some focused time with this book and few distractions to patch gaps in the knowledge I've acquired over the years and have finally been able to grasp concepts that evaded me previously. I'm particularly interested in Go's concurrency model which seemed so mysterious before but has finally clicked with the help of this book. One piece of advice for anyone using this book to learn Go is to download the source code when it's omitted for brevity in a chapter but type up as much as you can on your own while reading the relevant explanations given by the authors. What I really love about Mastering Go is that code is not shown in its entirety and then explained from the top down; it's explained (mostly) line by line which helps a lot when coming from a language like JavaScript or Ruby (like me), which oftentimes can be explained top down with no loss of understanding. Go's a different beast which is what makes it such a great language to learn. Like any language, it requires dedication to really learn properly, but the Go team has managed to create an amazingly terse language to solve a variety of programming challenges, keeping performance in mind all along. I highly recommend learning Go and absolutely recommend Mastering Go as a resource in that adventure.
