Course Description
Web API is usually the most important part in a web app.
This is how you expose your web app to the world, and to other users, and it must be fast, easy to use, and up-to-date.
gRPC is one of the most advanced and exciting web APIs in the industry today, and it adds a lot of value to any web app. Capabilities such as server and client streaming, strongly-typed messages, blazing-fast performance and more make it an important asset in every developer and architect toolbox.
And this practical, hands-on course will make you an expert in gRPC.
We are going to cover all aspects of gRPC, from the very basics to the most advanced topics.
Here are some of the topics we're going to discuss:
- How gRPC stacks against REST API
- Basic concepts of gRPC
- The 4 communication types of gRPC:
- Unary RPC
- Client-side streaming
- Server-side streaming
- Bi-directional streaming
- Best practices of designing gRPC API
- Using Protobuf, the message serialization format used by gRPC
- Error handling in gRPC
- Authorization and Security
And lots more.
Now, in order to make this course as valuable as possible, I made it extremely practical and hands-on.
We're going to build, together, a fully-functional, full-blown gRPC-based chat app, utilizing all the concepts we'll learn in the course, and we're going to use multiple platforms for that - nodeJS and .NET.
Note: You don't have to be a .NET or nodeJS developer to take this course. I'm going to guide you through all the steps in the development process, and make sure everything will work as expected.
By the end of this course, you'll be an expert in gRPC, not just in theory, but in practicality.
There is no other course like this! This is the only course that will take you all the way to be an expert in gRPC, from the very beginning to topics known to few, and will do that in an extremely practical and hands-on fashion.

Buen curso, aunque difícil de seguir el ritmo si no se tiene configurado correctamente el ambiente y no se le dedica tanto tiempo a ello; lo cual es entendible ya que no es un curso de programación de esos lenguajes, aunque comenta que no es necesario saberlo, pero puedes tardar sino estás acostumbrado al lenguaje.

Der Kurs ist didaktisch richtig aufgebaut, geht also auf Grundlagen ein. Manches klingt banal, aber das macht nichts, wenn man will, kann man das ja überspringen. Vielleicht kann Memi das nächste Mal etwas auf die Nebengeräusche achten, sein Mikro nimmt die dumpfen Tischgeräusche auf.

Another excellent training from you. 4.75 out of 5 stars from me. This training could only be improved if the four components were used in four different programming languages. My recommendation would be to add Python and Golang. Thank you very much!

Great course! It provides a lot of concepts and clarifies both the big picture and the details. The hands-on is very useful and helps a lot in understanding.
By Ben van der Harg on 12/26/2024
It was a good course, and I learned a lot about gRPC and some useful things about other technologies that built on top of it (e.g. gRPC Web). Overall I do think some parts could still improve: 1. In some cases the teacher asks to download pre-written code and incorporate it in your own codebase. Even though the code does get explained and discussed, I personally enjoy writing the code myself line-by-line to actually gain the experience of working with the libraries, seeing which parts do and do not get code-completed etc. I can imagine it would make the videos a bit longer, but I think it's worth the learning experience. Repetition does help to make it stick in your mind. 2. The explanation on OAuth2 is good conceptually, however, the actual implementation is very minimal and only concerns the client side. While in my experience (having implemented OAuth authentication in various ways), most of the work and complexity are on server-side which is barely touched upon, but could be a great way to introduce gRPC Interceptors (which are not covered by the course). Apart from the above I enjoyed the course and would definitely recommend it in combination with Clement Jean's Protobuf course (which goes a bit more in depth on how to use protobuf in 3 other programming languages).

It's a great course to introduce what is GRPC and how to implement a basic functionality using .NET Core. It covers most of what you need to understand when to use the framework and its benefits while keeping the focus in a practical approach. Thanks!

A very interesting course that shows all the essential aspects of gRPC. I especially liked the practical example that was used for explanation.
By Sebastian Ignacio Toro Severino on 7/6/2023
It is an interesting course that goes from the basics of gRPC and that is focused on the practial part. Imo the order of the lessons is correct and doesn't require any kind of previous knowledge, as the instructor mentions at the beginning of it. Keep in mind that the course is mainly using .NET. I would have liked to have some small examples with other types of frameworks as well, but no further knowledge about C# is required.

Very helpful to demo concepts behind gRPC. Those with DotNet experience will get more out of it, but as promised, it isn't needed. Excellent coverage of some of the more advanced topics. Doesn't spend too much time in the weeds and sticks to the gRPC concepts. My only minor issues: 1. Could use some more details for Mac/Linux users where extra or modified code are needed to get things working. 2. Boiler plate code is outdated if you have DotNet 7.0 Both of these are minor issues that are resolved with the help of the internet, but if you don't know the DotNet system, they can be a wrench in the machine. Overall very happy I took the course.

Another fascinating course by Memi Lavi, presented in a thorough, clear and interesting way and opens the mind to new ideas for implementation.
