Great stuff, thank you!
I appreciate your devotion to Go! Go has been a huge success with American Express and hopefully other major companies come along.
I like Go, but I see too much hate on Java these days. Java is not the bloated beast it was 10 years ago. These days I can boot a web service with a few lines of code. Later versions of the language also lets you write very compact code. With the addition of virtual threads in Java 19 it will also scale the same way Go does. I feel Java gets too much negativity due to cultural baggage, not because it's a bad language or plattform.
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 🤪🤪
It would be much great if you could accompany some of those points with benchmarks
Are we going to ignore all that smoke/steam going on in the back?
Go doesn't need a dependency injection framework because it doesn't have java beans. You can just use plain old construction injection.
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.
gorilla mux just died, please don't recommend it anymore
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.
Im not sure who hes worked for but every Java project uses Maven in my experience or at most Gradle. There is no proliferation of dependency management tools in the Java ecosystem.
Tried to get your cheatsheet but your website is down.
Can you please suggest some popular and fast Go framework for API development? Also which ORM shall I use? Any sample applications which I can look at? Thanks!
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.
bro are you still using java in your job?
Thanks. I’m a C dev who’s confused to choose between Go and Java to pivot my career towards web. This video helps.
@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.
NGL, a lot of new tools doesn't sound that appealing. Normally if you want a scalable product, you also want a stable, battletested, product. So having some older but reliable tools sounds better. (Ofc, not 20 years old :) )
Java is a good language with a bad (outdated) concurrency model. If Java had something like async/await (multiplexed onto a threadpool), I would use it, but the problem is that any library can spawn a thread and nothing can be strictly enforced
Executor framework?
Go is full of weird symbols. And it has no structure -I have seen production Go code where they would define an empty object and then have about 2000 lines of receiver methods in that file - but how you know they are all like that? You have to scan every one of them, unlike in Java where you would just need to follow the opening-closing bracket of the class to figure out everything in between is a class' method. Very hard to read language.
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.
Go is in the same Java stage in 2010. Probably in the next years, Go will have very popular frameworks, libraries, etc. They'll be industry standard and you'll be forced to learn them. In this moment, Go will be so boring as Java. Java standardization brought a lot of benefits for the development teams, since we don't have to take hard decisions like C or C++. Go is very lightweight and this can help companies to save money in a Cloud environment, since it doesn't require so much computation and a huge runtime.
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.
Simplicity and Performance are interested point to migrate to golang.
I've been using go for 4 years and never felt the need to use a dependency injection framework
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
Dependency injection: good!
Dependency injection frameworks: bad!
Yeah, it's not a bug that Go doesn't have a sanctioned framework.
Prototyping can be extremely fast in Java if you can move comfortably inside Spring or Quarkus ecosystem and if you skip the pattern gabbage. Gradle can be complex but the init command bootstraps your gradle project as quick as go mod init. Java is extremely robust and the invest into the recent java versions is pretty good. Its moving into the right direction, albeit very slow.
We migrated to net core
Java 21, WebFlux, RxJava, Micronaut and etc….
java compilation is slow? whaaaaaat
Go is more exciting than Java because is newer, and the ecosystem is starting to form, is just like Java was in the early 2000s
I guess version 1.22 fixes the http router issue.
How many companies migrated from Java to Go?
5
@@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.

What about node js , how is it performing in the industry should i learn it as I have javascript typescript background?
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 ?
Isn't Gorilla Mux abandoned?
Yes, it is.
yea i prefer GO, but in the midst of studying those machine learning and most of the things there using python as framework :|
Dude, something is burning beside you.
This and the fact that the owners of Java who is Oracle, and they're a garbage company.
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.
Go will be replaced with Bun in future
halfa year? lol wat what that enterprise java calculator? :D :D :D
WTF is this smoke behind your bed?
You see, when I hear jAvA, I instinctively twitch in disgust out of habit. Now, hold on, before you call me names, I also programmed in Java for over 3 years. If you are using hyping Java because "eVerYbOdy UsE iT". Then I don't care how famous the language, I'm talking about solo development. If you take two projects, one made with Java, the other with Javascript, then you would get 10/1 Time to code. And the Java code is only 50% faster than the Javascript one.
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.
Big techs have been firing. I hope soon propagate to small tech. Too many parasites in this industry with no better thing to do. To be frank it's a crime again humanity if anyone have the decency and the literary to understand what's going on.
In Ruby you can 20x performance by just not using Rails, Rails is just slow as fuck, use a standalone rack app is so much better alternative, Ruby is such a nice language that you don't really need frameworks. Rails has always been a mistake.
And if you use truffle ruby instead of MRI you are going to get 40x or 50x performance increase.
By avoiding rails and focusing on building small rack apps with nginx, roda and sequel you can scale horizontally better than with rails alone.
And if you self-host the predictable traffic of your platform and you only use AWS for the overloads you can save a ton on infrastructure.
developer time is a lot more expensive than cpu time.
but I agree, Go is always going to be better than Ruby and Python, because allows to save developer time and also simplifies deployment time because all you deploy is one binary.
sadly, most ruby jobs are rails jobs.
As a backend developer I very much dislike Dependency Injection
Can you tell more about your opinion ? :D
Ok you win!!!
Why
Then I doubt you don't write proper OOP code.
go is the shit. and it's documentation generator is the shit plus plus.
there is no way that documentation generator is useful - like javadocs lol
because java is garbage that is why the garbage collector pauses so much because is trying to collect the jvm itself 🤣
Java has only one selling point - it is widely used. There is nothing else good about Java. Java was a big improvement over C++ but now there are MUCH better and more productive languages than Java.
I mean, Java sucks. Always has, but it emerged at a time when there were few options to address the issues it was trying to solve. And it had a great marketing campaign behind it.
True!
But languages came and go ;-)
Go has lots of same things I hate about Java.
C syntax and dependency on environment variables, object oriented programming, lack of a sound type system that actually saves you from yourself or saves your future self from your past self and from the work of others from the past.
Go is strongly typed procedural language. You don't make much of sense.
Go is procedural, not object-oriented. Tf you talking about?
Lol
Java and C are the past, Go and Rust are the future.
