What you’ll learn

  • Understand the paradigms behind the Go programming language.
  • What an HTTP client is.
  • How to perform HTTP calls in Go.
  • Issues and blocks when working with native HTTP client.
  • How to design a Go library from scratch using Modules.
  • How to design a public API: Interfaces and methods.
  • How to provide mocking features out of the box.
  • Unit, integration and functional testing our HTTP client.
  • Most important: End up with a production-ready HTTP client that you can use without worrying about performance!

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!

    I can definitely see this course helping breaking through that initial barrier when it comes to learning a programming language. I’m positive I’ll finish it and hopefully master python by then.

  2. Abdallah Galal Abouhussein

    I would like to share my personnel experience, i`m very pleased and happy for taking this impressive course because Dr. Angela always makes it simple and easy to understand and always makes a precaution section before or after any bug that may appear to some students and also write or record the solution for us, and each word she said is very real and easy to understand.
    Thanks Dr. Angela

    Very good course. Dr Angela explains things very clearly. The exercises are interactive and helpful.

    Angela’s voice is like ASMR in most lessons. So you won’t lose focus?

  4. Jaime Sánchez Blanco

    Every concept is very well explained so you can assimilate it, and the teacher insists in practicing daily to get the habit of programming. It really motivates to keep studying and practicing every day.

  5. Bradley Carouthers

    3 days in and I’ve already learned more than other training programs where I’ve put months in. Her teaching style is both efficient and effective.

    Edit: Now on day 29 and the course has held up my expectations and hopes. The rise in complexity is not too sharp, and every day feels like an accomplishment. Angela takes her time to explain things without rushing, yet is able to pack tons of information in nuggets of time.

    Still recommend supplemental exposure for a more wholesome grasp. Though, this should be quite enough

  6. Tommy Prévost

    Very good course.

    PROs: lots of coding exercises, clear explanations, great examples, adapted to 2021’s reality.

    CONs: past the first 30 lessons, many similar coding hands-on.

  7. Quang Tu

    I love all the lectures and challenges of this course. I finally find myself in love with coding. This is definitely a fun course. Thank you Angela for this great course.

  8. Fortunate Eze

    This course is nothing short of AMAZING. The level of love and sincere desire to see students succeed present in this course is a rare sight. This course is fun, it’s challenging, it’s suspense-filled, it makes you feel good about yourself solving those challenges. You don’t take this course and memorise codes, you take it and you know what you’re doing because you literally do it yourself.

    It couldn’t possibly be any more obvious that Angela brought out her whole heart, time, energy and resources to give us a course that if priced based on it’s value, many of us certainly can’t afford. I mean, she kept advising and encouraging us to keep going, because she knows the road could get bumpy, she made a few jokes and used funny animations so we smile along the way keeping it fun. Why some people can’t see this and would rather subscribe to trying to bend courses to fit their own personal preferences is beyond me, but I guess people will always be people.

    Dear Angela, I cannot speak for everyone but I certainly can speak for myself and I’m saying thank you. The efforts you put into making this course outstanding didn’t go unnoticed.

    Let as many of us as appreciate your efforts make you happy and energize you to create more life changing courses for us.

    Just the course fits me. Learn by doing, it is easy to start and just follow the flow and at day 15 you realized how to program in Python. Then the magic happen. I am on day 27 and I am looking forward to start a new section everyday.

  10. Caspar Cheng

    Angela is my favourite teacher on Udemy, her courses always come with clear and concise demonstration, make it really easy to understand the content. Meanwhile, she also provide a lot of tips to encourage us moving further on the way of coding. I’m definitely a super fan of her. I had finished her web development boot camp and now I’m learning Python 100 days of code. This course is amazing as she provided one particular project for each day’s learning, which is, really useful and handy. Also, those projects are really interesting and won’t let me feel disappointed about myself. Although some of them are a little bit difficult, they’re still resolvable after some struggling and searching online. I’ll recommend this course for those who really want to learn Python well and write real python projects from scratch!

  11. Jonas Weber

    The course was awesome in the first half! Really helped me to get back to programming and learning new techniques. Also the course got way to much focused on web development in the second half, which I’m not really interested in and is redundand to your dedicated web development course. The lack of videos in the last quarter was rather sad. I really would’ve liked some video explanations for pandas and matplotlib. The challenges and capstone projects were great and challenging!
    All in all I can really recommend this course for beginners and those who want to learn python and/or get back to programming!

  12. Rohit Prasad

    Angela is the best teacher I have ever experienced. The way she explains all the topics and makes use of it in the projects is commendable. Thank you so much Angela for this course.
