Building a module in Go (Golang) (Udemy.com)

I have taken a number of courses from this instructor, and this is one of the shorter ones, but I have to say I have had a lot of fun working through it. Students are walked through the process of building, testing, and publishing, and versioning a Go package that contains a number of utility methods for web development.

I have taken several of Trevor Sawler’s Go courses, and this one stands out as especially practical. Trevor’s teaching style focuses on quickly demonstrating real working code and then applying it in ways you will actually use in real projects. What made this course different for me is that it forced me to follow along rather than just watch. Repeating the steps for building modules, updating versions, and working with Go workspaces builds real muscle memory. After a short time, concepts like project organization and reuse stopped feeling confusing and started to feel natural. If I had finished this course when I first bought it, it would have saved me a lot of time and frustration. Many delays in past projects came from not fully understanding how to structure reusable Go code. This course would have eliminated much of that. If you are serious about Go and want to stop rewriting the same code across projects, this course is absolutely worth taking.

A good introduction to creating Go modules with simple examples that includes guidance on publishing repository versioning. By the end of the course I had successfully created my own Go module, published it, and imported it into a new project. -- Thanks Dr. Sawler, your courses are always a pleasure and, though some may not, I appreciate the dedicated time you give to writing testing and consistently updating them. Too often in my teams I see this being overlooked as an afterthought or as a separate task, but the way you incorporate that flow into every feature for your courses is how we should all operate as professional programmers.

Overall OK, but I feel there were too many errors made by the lecturer. It's OK to have a typo and correct it "live", but I think that bigger mistakes - as e.g. malformed json spec that makes the app not compile - are too much, and should have been edited out. As it is, the course feels hastily made, without much attention to detail. The other courses by T. Sawler I've attended so far were top notch.

It was a very nice course. I have some suggestions: the second example was a bit long (or complex for me), maybe it should be at the end. In my case, some projects were not easy to understand the objective, it would be nice if at the beginning of each lecture we can got a view or a simple diagram of the functionality. Thanks.

Content, instructor's knowledge, pace, all are great. I'd recommend the course to all of you out there if that's the kind of content that you are looking for. As for me, it was a bit more advanced than I first thought. I am very new to Go and new to web development, and so it wasn't really possible to follow and understand all of it. But, that is about my level. Thanks for the course!

Another very useful course within the Golang programming series from Trevor Sawler. Once again I found this course very practical, not only from the point of view of handling JSON but other practical aspects such as using workspaces within VS Code and the principle of semantic versioning. The result is a useful module for future projects. A very practical course from an equally practical teacher... highly recommended.

The course starts strong by getting you started with organizing your project in sections 2-3. Then it all pulls together in section 9. The prior sections are there to help reinforce the importance and how to write good tests, but a good listen. I will definitely implement this pattern of creating modules in my future work as it keeps everything clean and separated into individual projects, making things manageable when the code base starts getting large and you work with multiple teams. This course is an excellent addition if you want to learn how to organize your GoLang work for others and your future self to consume.

The content of the course is nice and the result of having a simple toolkit is good. But it is hard for non-native listeners to follow the videos and writing the code while listen. There should be some more breaks for writing them. Otherwise it will leads to, that all code will be downloaded instead of writing it. And imho it is better if trhe code will be written by very one as self to understand them.

I wished there was more background on Go modules, for instance, before Go workspaces have been introduced and afterwards, a bit more about the best practice to structure a project and the use of go commands to deal with modules and packages. There is more focus to create small utilities that are then delivered as part of that module. This is nice for doing some initial steps with Go as you code along with the instructor, but conceptual background is missing. I would find it better, if the instructor left coding the utilities as a challenge for the students, of course giving hints how to solve this in order not to get lost. It is good that the functions added to the module are also covered in a module test. Here again, I'd expect a brief intro to not just code along w/o knowing the details. It is a pity that the instructor doesn't write the tests first before he codes the actual function, as this would teach students the TDD-approach. Overall, the course delivers what I'd expect but I wished more theoretical background was provided.
