Why are Companies Migrating from Java to Go? 

But its tainted by Oracle

@@johnyepthomi892 Go is tainted by Google. Typescript is tainted by Microsoft...

@@johnyepthomi892 ​ Had people from Oracle visit our company few years ago. They wanted to sell our product on their Oracle Cloud marketplace and also tried to convince us that their Oracle DB is better than Postgres that we were using.🤣We literally laughed at their face.

A few lines of code and a couple hundred megabytes of runtime environment

tfw open the task manager and see how bloated jvm really is, spoiler alert, it's even more bloated than a web browser literally. It's only a personal server? how is it taking so much memory ? because it's java 🤪🤪

True... Time to replace it with chi or some other minimal library.

@@hermes6910 Just no longer being maintained so it's not getting any new features nor security updates

I like echo

Let’s drink Gin to it 🥃

This is the problem with not having a first party support for basic stuff, like websockets. Compare this to ASP(c#) you will never see Microsoft doing this to it.

I personally use pocketbase for my startup. But if you are looking for extreme performance and ease of use, you should go for gofiber

API's don't really require a framework at all, but if you feel inclined to use something, Fiber is good (though it's not compatible with net/http), so is Echo (same incompatibility as Fiber) or Chi for routing. GORM is a nice ORM that comes with a lot of useful methods.

The Go standard library has great general purpose library for building web services called "net/http". It is best to learn this first and then look at other frameworks and packages. Most other frameworks and packages have a specific focus or purpose. It is best to start with built-in library and then add things depending on what you need/want. For example the Fiber framework uses a modified router (fasthttp) to be much faster than the built-in net/http. The tradeof is that it does not implement HTTP2 and uses custom (and smaller) structures for the http requests. So it is faster for small/medium requests but cannot do other things and does not integrate well with other tools because of the custom structs. Also be aware that in Go there are not just big frameworks that do everything. Since you can do everything with just the standard net/http, there are a lot of packages that just do 1 specific thing. For example just a router package, or just a middleware package, ... You can always combine multiple packages depending on your needs. Once you know the standard net/http you can look at other packages/frameworks. Some interesting ones are: - Gin - Beego - Echo - Fiber - Chi - Buffalo

@@NotMIFood thank you

I like Gin-gonic.

But old construction injection is hard when you have many objects that depend on many other objects because you must be careful to instantiate the objects in the right order...

It's not hard, you just type your params and your ide won't let you fail. And that's true for any language.

@@fieldmojo5304 you must be very careful to create the right constructor and use just the right one and you must be careful not to send null pointers... With dependency injection framework it is so easy to make sure you always have the right objects ready to serve the client objects and at the right moment.

It's not about java being boring, but it being a crap. Other even older languages aren't that hated as java because they're not THAT bad.

@akashic seer Don't be that angry and come to rust

@akashic seer And you have got rust for that, as long as you have rust installed, after compiling what else will you need?

@akashic seer What language should I learn if I am at the start of my career and interested in working as a backend developer? I know C, a little of C++, python and basics of Java and seeing the hype around Go I was thinking to learn it but now I am really confused

@akashic seer I see, I'll do that thank you so much for the insight :)

​@akashic seer Because c and cpp are terrible languages.

How do you structure and test your code without dependency injection?

​@@krigeDI using construction bruh!! Why the hell u need a framework for DI????

true, just manually wire everything together in the main.go Imo it is much easier to debug and navigate than placing some magic annotations all over the place

Plus if I remember correctly it has no final modifier, right? So while I am scanning some code I have to keep track within that function/method for any possible change in that variables, whereas in Java I just label the variables as final and let know the reader he can continue reading without worrying if the variable changes later on.

@@IvanRandomDude Could you provide some proofs, please. And when I say "migrate" it means total refusal to use Java but not use Go only in some new projects. How many companies have replaced Java code with Go code? I don't like Java, I really like Go but I hate click bate titles and messages! The truth is: there are many companies used Go for new projects or modules.

​​@@aka_vitfil 1 - Shiprocket 2 - Gojek 3 - ConnectWise 4 - Swiggy 5 - Uber (Micro Services) 6 - Bank Of America

Uber, American Express, Master Card, Netflix, Bank of America, a lot of Banks, Docker and previously Discord, all use go now. I am former java dev and senior dev for one of the North America's biggest banks, and we migrated our entire payment gateway backend to go over last couple of years. And we process literally 78% of all NA's large B2B transactions. Now we are migrating document management service and Loan Origination application to go

@@theashenone564 Awesome job! But what the real profit of this migration for business?

Yes

If one would suggest Java developers to migrate to go then it would certainly be the same for javascript developers. Although javascript/typescript is probably the biggest ecosystem, I don't see companies switching from anything to it in the future. Nodejs has it's place but it can never compete with "real" languges in terms of performance and reliability, Go will beat nodejs in terms of performance by a big margin in almost any case while it still maintains the simplicity that you get with nodejs, and you don't have to deal with all the bs that comes with javascript.

that said, if you just want to get a job as quickly as possible and you don't care about anything else, then learn nodejs.

@@hermes6910 But wouldn't you agree that go is even easier to deploy, you get an executable and execute it, while with node you have to deal with actually having the nodejs installed then pm2 bs, versioning etc... I'm actually not a Go dev, but to me Go doesn't seem like a "low-level". And my advice was aligned with the narrative of the video. Again, my opinion is that, same as companies are moving from Java backends to Go backends, they will be moving from Javascript backends to Go backends as well. Doesn't mean either Java or Nodejs are now suddenly extinct, in fact they're both bigger than Go currently.

@@nerminkarapandzic5176 I’m a go dev, and very few entry level devs are hired into go roles. It’s better to start with node as it will be much easier to get a job and experience and then learn go and apply those backend principles.

​@@hermes6910 is it a Linux ?

Yes, it is.

Executor framework?

Java virtual threads

Learn Project Loom.

I use java 21 and Spring boot. Currently thinking to learn Web Flux. We have Virtual Thread and graalVM. Do you think i should learn webflux?

But most companies don't even use Oracle Java anymore. Sure, they are still the ones designing the language. But many companies gravitate towards open source Java like with OpenJDK

it's garbage inside out all the way down the very moment you have a corporation calling all the shots.

I mean the IDE itself fills in 90% of the stuff with autocomplete / intellisense. What are you complaining about? I can write C# or Java code in half the time that will blow your Go code out of the water. I can also write Go code in half the time that will blow your C# or Java code out of the water. The problem is your code not the language. Please don't be stupid.

there is no way that documentation generator is useful - like javadocs lol

sadly, most ruby jobs are rails jobs.

Can you tell more about your opinion ? :D

Ok you win!!!

Why

Then I doubt you don't write proper OOP code.

Go is strongly typed procedural language. You don't make much of sense.

Go is procedural, not object-oriented. Tf you talking about?

Lol

True! But languages came and go ;-)
