Awesome Content ! Precise

[@farishuskovic8486]

Thanks Tensor. I started learning Go in the middle of 2018. The Golang videos you've put out have definitely been a contributing factor to me further exploring this technology. Really appreciate the time and effort and look forward to future Go videos. I recently started learning React. I noticed you're profile pic is of the react symbol but you don't have any react videos. I definitely have an interest in combining Go and React into a stack along with an advanced API technology like using protobufs and GRPC or GraphQL. Wondering what your thoughts are on those technologies or if we might see something like react and or Graphql on the channel in the future ?

[@TensorProgramming]

Firstly, thank you. Its always great to hear when people find my content useful. I make this content to help people learn and if I've helped at least one person then I've done my job. Its not actually a react symbol; its an Atom. I mean of course its also the react symbol but that wasn't what I had in mind. I've done some react reasonML stuff on this channel and I do have plans to do some clojurescript stuff with OM/OM next, but there will be no JavaScript based tutorials on this channel for the foreseeable future. The main reason for this is due to the fact that there are a ton of JavaScript/React tutorials already out there. Also, I don't personally like using JS when I can avoid it. GraphQL on the other hand is a thing that I certainly love to play with. I have some stuff on it with Elixir and also intend to add some Go based GraphQL stuff in the near future. Likely, If I do a large project with gRPC/GraphQL and Go, the frontend will be built with a language like Reason, Elm or ClojureScript for the sake of those users.

[@JalerSekarMaji]

It gives me more insight about the implementation of gRPC. thankyou very much!

[@adilrasiyani4240]

For Mac, if you use brew you can install everything with brew install grpc. It will install the proto stuff for you automatically.

[@RajeshSamson]

Great explanation ... very beautiful video

[@PandemicGameplay]

Question: is GRPC async? I guess my question is how are multiple clients handled since you are using only 1 connection throughout the lifetime of the main client server?

[@TensorProgramming]

The protocol gRPC has nothing to do with the synchronicity of the client/servers; its just a protocol after all. That being said, you can make asynchronous calls with gRPC data just as you could with JSON data or XML data. Our server here can handle multiple clients as it currently is since we are serving over TCP. Thing is, you don't have to manually create a bunch of concurrent logic with servers in Go. The "net/http" library naturally uses Concurrency/Goroutines and so when you call http.ListenAndServe you spawn as many goroutines as are needed to handle the incoming connections. If you want to try it for yourself, just make a simple http server with go and open a bunch of browser windows at the same time or create a client which pings it multiple times with many different go routines.

[@feziletati2958]

Great tutorial, well done.

[@romsthe]

So your client is actually a REST server itself, could be confusing. Well good tuto anyway, I never used golang but it was easy to follow and understand. Thanks a lot

[@TensorProgramming]

This client is a rest server sure, but it can be any type of client you want, a CLI, a GUI etc.

[@SouvikHaldarmustang]

One point seems to be wrong:- The numbers beside the fields are not their size but their position in the structure. Correct me if I'm wrong.

[@cryptopatrick]

Absolutely amazing videos! I went through the RPC video, took study notes, and then wrote the code as you instructed in the video - made my first RPC calls! YAY!! :D Mr. Tensor, may I ask: what is your goto language? If you just want to explore an idea, what language do you usually reach for? Cheers!

[@TensorProgramming]

It really depends on the use-case that I am working on. I've never really been the type of person to stick to one language for everything because I often find that there are better solutions. I like Go for microservices and for small-medium backend web apps. I also like Rust for small-medium backend web apps and for WASM compilation (and some games). I like Elixir for Microservices and Larger Web apps along with Clojure for Large web apps and ML etc.

It's nothing personal, but the one thing that drove my classmates and I crazy the most is when you're following a tutorial and the author makes some sudden jump or does something all of a sudden that makes no sense and they don't explain why they did it. That's exactly what you did with third_party. If you're assuming that the audience doesn't know the most basic of things, like how to download gRPC, why would you assume that they would just know why to create the third_party folder and what to put in it?

I do explain where the third_party folder came from and all that. The main issue I think you and your classmates are seeing is that it pops in and out of the video because that little part at 2:30 was recorded after I had gone through the stuff at 3:10. Basically, I went back and recorded more explanation while I was editing the video because I felt that it was missing. At the time, I should have just overdubbed it on a few looped frames but I didn't think to do that. Glad you enjoy the content regardless.

[@shayaxelrod7691]

Welcome to the Golang! Any COD fans?

[@Wallawallawallawalla]

I think you mispoke when talking about the use of the field number. It isn't used to specify the size of what is stored in it, it's used to have a small reference to the field so it may be identified in the message binary format. Field numbers 1-15 take do take just one byte to encode, and should therefore be reserved for frequently occurring fields. The type (as in actual type like int64, string, etc) of data in the field should never influence the field number. Source: am googler, use these every day, and double checked my expectations against the docs to verify.

@@Wallawallawallawalla Its not a problem. Thank you for pointing out the issue. Another subscriber mentioned the same problem a little while ago when the video came out. One of the side effects of doing everything "Live" is that the explanations can suffer somewhat. I did try to make the concept clear in the follow up video on gRPC so I am hoping that makes up for it (since it is a fairly fundamental concept for gRPC and protobuffers).

I'm caught between this go grpc stuff and phoenix liveview. I appreciate it's a bit like comparing apples and oranges but I want to start a new project for my github resume and want to know which you suggest I start with. I can't bear json restful, I come from a c++ desktop background so both grpc and websockets seem a much better way forward. Just your thoughts on this really please.

[@TensorProgramming]

With both you can setup websockets and serve your data (GRPC can be restful and LiveView is all about phoenix channels). If you really want something that is graphically focused then liveview is really the way to go. And if you don't want to have to mess with JavaScript frameworks; then I also recommend LiveView. On the other hand, you could do a stack with go GRPC as the main backend and some JS frontend framework if that's the style you prefer.

in 1:40, I extracted it on C:/Program Files/protocolbuffers, then I ran the protoc --version command but the protoc command is not recognized, how was that? where is the right path? well my Go directory is in C:/Program Files/Go and go run is working anywhere...

[@TensorProgramming]

Its because you don't have the binary for protoc on your path variable where as Go must be if its working anywhere. Look in the protocol buffer folder and you should see a bin folder which has the proper executable in it. If you add that to your path variable then it will be globally available in any terminal/command line; otherwise you need to use the full path to it for the terminal to know what you are referring to.

[@empaguia]

[@danielvega646]

What I want to know is... Another company has a regular API on RESTful architecture, is it possible to send a POST request from my gRPC API? And if not, is it worth it the process of passing my gRPC request through some proxy that converts it into regular REST request and viceversa? The JSON response from the REST api is it worth it to translate it into protobuff for my gRPC API? Or I wouldn't notice an improvement in performance and just a regular REST APIs connection would be enough?

[@TensorProgramming]

You can call rest apis from a gRPC client via certain plugins. Theres one that lets you encode the data to/from Json. You won't get the advantages of using protobuf from these calls, but it doesn't add any extra overhead to a normal rest call. In other words, you don't really need to build your own logic for this, just use one of the many plugins.

I was thinking... Well, I just need to do the regular REST JSON HTTP 1.0 POST request to the vendors API inside my microservice gRPC method, retrieve the response and propagate it back through gRPC to my gateway server and then it can answer to my client graphQL request. Does that architecture make sense? I am new to this, I am sorry if what I am saying sounds stupid.

No you really don't need gin-gonic nor does the language need a lot of library support. Go's standard library has tons of http stuff in it (along with many other useful things).

what about returning slices of structs and structs in structs// . for GoLang. What would the Protofile look like and how would they be addressed?

[@TensorProgramming]

You should checkout the syntax rules for protobuf: developers.google.com/protocol-buffers/docs/proto3 You can use the repeated keyword to specify that you want to return multiple items of the same type with the same name. If you wanted to return a slice of a struct, you would define the struct in the protobuf and then wrap it in another message marking it as repeated.

Thanks for the video. My question to you, what's the point of using Protobuf and gRPC if you're going to be using endpoints and JSON?

[@TensorProgramming]

Well this particular example is a case where you might want to have two individual microservices on the same machine or on multiple machines and then you want to serve the data through a RESTful API. You could always not use the JSON endpoints and make a client that just uses the data. While this example is fairly contrived, I have built systems that have similar architecture in the past. A service that deals with a database, a service that deals with the business logic on a server, a service that serves content through nodes and a client. Its a pretty common architecture pattern with microservices that are service some data or service to other devs/users.

[@mustache2295]

So, basically, I'm a noob and all this pretty much went over my head. What knowledge serves as a prerequisite in understanding this material? I've only recently started studying programming and such but mostly I've been studying web development. As of now I've only reached JavaScript after learning HTML and CSS. I've also learned a bit of Python but truthfully still at a very basic level for it all, really. I've also just learned about API's and have been researching them since TechLead says that coding is so "10 years ago" and that you should be using API's and I'm not really sure what he means. After some time researching API's I am still rather confused as to how it fits into the puzzle of programming. Can you help me understand this a little better? I apologize for any vague language I may be using. As I said, I'm very new to programming and I'm just trying to improve my understanding of the technologies before me in order to make an informed decision on the skills I should be focusing on. Thanks, Ian

[@TensorProgramming]

You probably shouldn't listen too much to what techlead says. That guy tends to be hypercritical/hypocritical and hes opinions generally are not very relevant for the average developer. If you want to learn about RPCs and APIs, I recommend that you look into the basics of building servers and the difference between client and server side architecture. There are many different ways to structure a web app; you can build serverless apps, client side progressive web apps, servers with API endpoints that feed into multiple clients, servers that use server side rendering with small clients etc. APIs and more generically RPCs just serve the purpose of connecting one application to another. They are interfaces that define how an application can access some data from another application. When you get on a website like Facebook or Google, your browser accesses a client facing web application which renders out the user interface (Html/Css etc) and that app fetches data from multiple APIs to allow you to do things. There are also many different types of APIs that you can use; GraphQL, Rest, Restful, SOAP, Json-RPC, Proto-RPC etc. Start with something small; for instance, you can look at my Go playlist and follow along with the Wiki series (its old but most of it should still be relevant) or you can find whatever other resources are out there for building basic web applications.
