Course Description

Have you ever called a REST API from your Go program? Did you implemented your own HTTP client or did you ended up using some of the thousand libraries out there? Do you know what your HTTP client is doing in the background?


In this course we're starting from scratch! We're going to remember how a basic HTTP call looks like by digging into the request & response objects. We're going to write a basic HTTP client to perform HTTP requests and then use it in productive applications. What issues do we have? Can we scale our applications by following this approach? Of course not! That's why we're creating an HTTP client library that provides:

  • Fast, reliable and friction-free HTTP connections.

  • Support for all HTTP methods: GET, POST, PUT, DELETE, PATCH and more!

  • A Concurrency-Safe HTTP client that you can use without worrying about performance.

  • Content type management and optimization.

  • Mocking features out of the box.

  • A clean interface in case you want to unit test your code without relying on integration testing features.

  • A robust implementation so you won't need any external dependency whatsoever.

  • Completely customizable interface: timeouts, transport layer, custom HTTP client and lots of useful features.

  • A library that is PRODUCTION-READY!

If you're looking to integrate a 3rd party REST APIs in your code, you'll need to perform an HTTP call to it. Make sure you take a look at this course before even considering alternatives out there that will force you to use different dependencies for running, testing and extending your code! As Robert Pike says: "A little copying is much better than a little dependency". In this course we're not only getting rid of the dependencies but we're also getting rid of the copying. We're not using anything more than the Go's standard library to design & develop our own HTTP client.


This client will the baseline for all of the applications we're going to build later, making our business scale and grow as fast as we can Go.


Take a look at the preview lessons you have available to have an idea about the structure and content of the course. I know you're going to enjoy it! If you have any doubt, take a look at my other courses and see what my students have to say!


See you on the other side!

Hi! I'm Fede, a graduated Software Engineer and Software Architect from Argentina, with over 15 years of experience building real-world systems that run in production every single day.


I specialize in designing and implementing high-performance microservices, cloud-native infrastructure and scalable backend architectures. I’ve worked across startups, enterprise systems and now lead the development of tools and platforms used in production environments.


But beyond writing code, I teach and I do it with a hands-on, real-world approach. My courses are built from real experience, not just theory. If I teach something, it’s because I’ve used it in critical systems and I know it works.


Expect practical examples, clean architectures, modern tooling (Go, Kubernetes, CI/CD, gRPC...) and content designed to make you productive from day one.


Let’s build something great together.

There are definetely some things I learned from this course regarding how to structure my Golang projects and some idiomatic ways of building interfaces and structs. But overall until now the return on investment is not the greatest. The tutor does explain things often in a great manner but also I feel like a lot is beeing omitted or the reasoning is incomplete.

As i have Udemy for Business I am doing many courses at once and I can tell you, this is one of the best Golang courses out there. It's very easy to follow and the contents are very good.

By Anonymized User on 12/23/2021

I liked this Go course, because it is showing the real programming practice. Choosing "HTTP client" as an example app is a very good idea :)

By Sidharth Mohanty on 8/20/2021

Nice explanations, and I am always a fan of Federico. The videos are sometimes long but it's not at all a minus to take this course.

By Henrique Alexandre on 6/24/2021

Teacher has charisma and engages really well with the content and virtual audience. The code he delivers is outstanding. His code is also outstanding. Kudos!

By Gustav A. on 3/27/2021

Apart from the tutor is unreachable for Q&A, this course is great. I would appreciate if the tutor did showed everything he does recorded instead of off camera.

By Tom Price on 2/13/2021

Great course, please do some more. Also, please make all the changes as lectures, so we can understand what you've done without having to search your code.

I found this very difficult and frustrating to follow. The IDE the presenter is using is black on black which makes seeing what file the presenter has active almost impossible. The presenter is constantly jumping between open files, deleting things and cutting and pasting all over the place. This means it takes 5 times as long as the video to attempt to follow along. If you are trying to follow along on your own you will see there are parts of chapters that appear to have been edited together and code will appear in the presenter's editor that you don't have. There is constantly broken code(red in the Goland IDE) and the author doesn't bother to make sure it's all fixed before moving on to another chapter. This makes for an incredibly frustrating experience. Given these things I'm wondering if the point is just watching someone else code. There is also no reference to a stable git version before or after each chapter.

Excellent course. Really appreciate your work. Thanks for shortening lectures and awesome content. I have learned a lot. Looking forward for next high quality content from you.

By Markg on 10/7/2020

I have all of Federico's courses, he's an excellent instructor and to me his courses are simply the best, real world design, clean code, great examples, well executed, cant wait for the rest of his courses - keep them coming federico!
