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.

Go doesn't need a dependency injection framework because it doesn't have java beans. You can just use plain old construction injection.

[@tongobong1]

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...

[@fieldmojo5304]

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

[@tongobong1]

@@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.

[@dandogamer]

I've been using go for 4 years and never felt the need to use a dependency injection framework

[@johnboy14]

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.

[@albtein]

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.

[@gato-rs]

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.

[@lubeckable]

bro are you still using java in your job?

[@kqvanity]

It would be much great if you could accompany some of those points with benchmarks

[@fischi9129]

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 :) )

[@TheSiddhaartha]

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!

[@johnsonkengne6229]

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

[@banditosdoritos]

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.

[@NotMIFood]

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

[@anxaje]

@@NotMIFood thank you

[@CheefCoach]

I like Gin-gonic.

[@nyahhbinghi]

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

[@lmaoded7505]

Executor framework?

[@always-ask-why]

Tried to get your cheatsheet but your website is down.

[@kozas0]

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.

[@kozas0]

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.

java compilation is slow? whaaaaaat

[@MrJohnnyImba]

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.

What about node js , how is it performing in the industry should i learn it as I have javascript typescript background?

[@nerminkarapandzic5176]

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.

[@nerminkarapandzic5176]

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.

[@nerminkarapandzic5176]

@@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.

[@mfc1190]

@@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.

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.

[@vacc1001]

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.

[@laughingvampire7555]

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.
