Node vs Go for a REST API | Which is best?

Node vs Go

This articl is about which is best Golang or Go and Nodejs when you’re making a rest API.  When would someone choose one over the other for REST API’s and I think that’s an excellent question, you see the thing that I consider when I use Golang versus Nodejs, it basically just boils down to two main things and that is whether or not, I need what node is offering as opposed to what nodejs is offering now.

I know that’s a little bit fuzzy but let me walk you through the same, so the benefits of you seeing something like nodejs, it’s all JavaScript and depending on your viewpoint, that’s a good thing and a bad thing will touch on exactly why that is in just a moment. But what is fundamentally good about nodejs is, that there are a lot of resources both learning resources, there are tons of libraries, there are tons of tutorials, there’s so much.

Golang really shines when it comes to REST APIs

Node vs Go

Now go comes into picture that JavaScript does well, it’s easy to access, it’s easy to learn, and it’s also very easy to find people who know it the amount of people that you will find that know JavaScript is going to be failed, like there is a lot more people who know JavaScript and there are people who know go now.

When would you use Golang, if javascript is such a good great thing, the thing is that Golang really shines when it comes to REST API’s. If you’re looking for performance and types, why in the world would this thing matter! Well performance if we look at performance for example go has the ability to actually leverage more of the machine that it’s running on, you can run multiple threads, you have all these different like Golang routines.

For example, it can actually squeeze more out of each container because I’m assuming that you’re running things in a container than node will be able to do. Now you can do certain things like you can create multiple thread workers and so forth nodejs, but in general, you don’t! That’s where go really comes in and it kind of comes into its own. Go is really great for a small service that needs performance and a REST API depending. It kind of depends of course, on the size of the REST API as well, but for the most part it’s a really great choice for that sort of work.

JavaScript doesn’t have a type system at scale

Node vs Go

Second thing, I mentioned was types now the biggest problem with JavaScript is that, it doesn’t have a type system at scale, trust me guys at small-scale it may not matter so much but it becomes a really important at scale and it also becomes important in very specific sort of situations, where you really need a type system to work effectively.

I’ll give you a great Example, never ever if you can avoid, it create any type of application that uses JavaScript, you have to do money calculations with a lot of rounding and stuff of that nature because it simply is not good at that sort of work, if you are simply taking in data saving it to a database and sending it back to somebody then node is perfect but go has a typing system and it doesn’t have all these sort of issues, so for me it really boils down to what type of application that you’re writing if you are making a REST API it read.

As I said, it really depends on your setup if you are making a standard simple REST API, for you that does not have a very specific type of use case then I would choose nodejs because as I said there are a lot of other benefits to using nodejs.

NodeJs is great for boilerplate

Node vs Go

In theory, you could use something like typescript for example, or flow to get the typing system but on average that’s the way that I think about it.  I said nodejs is great for boilerplate like you suddenly some standard type of rest API, but if you need to squeeze the absolute living out of the performance or you need a typing system to help you out.

In other words you have a really large rest API or maybe you’re doing something like stripe for example like a payment providing type of rest interface then go every single day of the week because, it’s going to handle more load over time and as I said with the typing system you can actually maintain your code and keep it good for longer that’s at least how I feel about it.

So that’s a kind of where it boils down to you go with nodejs if you’re making something small or something very standard that doesn’t need any type of specific thing, it’s just a normal old application or normal old rest API and you go with go if you need extra performance and a typing system that’s at least how I feel about it, this actually exactly what uber found to be true for them when they switched over, they have a lot of nodejs microservices in their ecosystem and one of them was specifically under a lot of stress because it was needed in order to make a lot of other services work.

So it was like bombarded by tons and tons and tons of requests every second so they rewrote that in Golang in order to improve the overall performance because they could actually realize that they could actually squeeze more out of the hardware that the  container was running on by simply leveraging go. So that’s my answer to you use nodejs if you don’t have anything specific in mind and use Golang if you need a type system, in other words you’re dealing with money or some type of very advanced rest  API and you need the extra performance.

What exactly is Node.JS | Introduction, Benefits of Nodejs

introduction of nodejs

Node.Js introduction

Node.Js is an open source and cross-platform runtime environment for executing JavaScript code outside of a browser quite often we use no to build back-end services also called API’s or application programming interfaces.

These are the services that power our client applications like a web app running inside of a web browser or mobile app running on a mobile device. These client apps are simply what the user sees and interacts with, they’re just the surface they need to talk to some services sitting on the server or in the cloud to store data, send emails or push notifications to kick off workflows and so on.

NodeJs is ideal for building highly scalable data-intensive

NodeJs is ideal for building highly scalable data-intensive and real-time back-end services that power our client applications. Now you might ask but most there are other tools and frameworks out there for building back-end services such as a Spirit, Rails Django and so on. What’s so special about Nodejs is easy to get started and can be used for prototyping and agile development but it can also be used for building super fast and highly scalable services.

It’s used in production by large companies such as PayPal, Uber, Netflix, Walmart and so on. In fact at PayPal that rebuilt one of their Java and spring based applications using nodeJs and it found that the node application was built twice as fast with fewer
people in 33% fewer lines of code and 40% fewer files and more importantly they double the number of requests served per second while decreasing the average response time by 35%.

So nodejs is an excellent choice for building highly scalable services.

In NodeJs applications we use JavaScript.

We use javascript in nodejs

Another reason for using nodejs is that in node applications we use JavaScript. So if you’re a front-end developer and know JavaScript you can reuse your JavaScript skills. A full-stack developer can get a better job with better pay you don’t have to learn a new programming language.

Also because you can use JavaScript both on the front end and on the back end your source code will be cleaner and more consistent.  So you will use the same naming conventions, the same tools, and the same best practices.

And finally another reason for using nodeJs is that it has the largest ecosystem of open source libraries available to you, so for pretty much any features or building blocks you want to add your application, there is some free open source library out there that you can use. So you don’t have to build this building blocks from scratch and instead you can focus on the core of your application.

7 Reasons to use Node.JS

7 reasons to use nodejs

The blog is about, seven reasons to use Nodejs and I could have come up with ten or five but I decided to go with 7 because it’s just stayed off the top of my head. Without having to do a bunch of research and I’ve created some Nodejs frameworks and I’ve worked with the frameworks with many of them out there like, ExpressJs.

The Seven reasons to use NodeJs

And I’ve also hosted a few NodeJS websites, so anyway I’m just pen down the pros because people have asked me – how do you choose between node and Python and this isn’t really a comparison directly between Dot net and Python. But I’m just going to go ahead and list some of the reasons, why I would use NodeJS and why I think it’s a good choice!

The First reason to use NodeJs

Source: nodejs development services

So number one, it’s really fast and when I say that it means, it’s non-blocking. So what is non-blocking, file reading and writing is one of the things that servers need to do really well and that’s something that NodeJS does, as well as it is able to read from a file system or a database and then you know to send that data back, you’re not going to find a better technology out there, so the chrome v8 JavaScript engine was what Nodejs was built from and it’s extremely fast.

If you look at the core code, that actually makes a makes up the node.js framework. Now, you’re looking at a more low-level code as compared to a language like JavaScript. Also, it is used by many modern companies and a lot of major companies are using it but just to name a few, LinkedIn, Walmart their entire web stack is built on node then PayPal, uber and Netflix so those are all major companies that are scaling Nodejs.

The Second reason to use NodeJs

7 reasons to use NodeJs

one language for the frontend and backend. Another reason why you would want to use node is that you’re going to be forced to write JavaScript for your client side and you’re going to be probably using one of the modern JavaScript libraries like react or angular or ember or any of the millions that it seems like we have. That means you will be writing JavaScript and it’s so much easier than Python on the backend or Java, c-sharp and then having to switch over to JavaScript on the frontend. You can write JavaScript.

Because JavaScript is how you interact with, it is the language that actually write your NodeJS website. So even though you know Nodejs at it it’s a technology and it’s the chrome v8 engine and also written in c JavaScript is what you actually write, so being able to write JavaScript on both the front end and the back end it goes a long way especially when you know it really goes hand-in-hand with use a react angular and ember and all the other frameworks.

The Third reason to use NodeJs

Cross-platform and this is a huge deal because if you’re going to run a node.js application, you might need people that might need to run it on a Linux web server or it could be a Windows web server or even you know running it on a Mac. So the fact that Nodejs can install in all those machines whether you’re running Linux or Windows or Mac and you’re going to be able to run the application so you have Microsoft and c-sharp.

You know moving with they’re not there, Dot Net core over to a Linux based system so it works on Linux because that was always a major disadvantage for Microsoft and c-sharp was that it didn’t run on Linux and Nodejs doesn’t have that problem so it’s a major benefit!

The Fourth reason to use NodeJs

7 reasons to use NodeJs

One of the most active development communities. If you look at the communities, the amount of questions that have been asked on not just JavaScript but also on Nodejs, it actually it definitely competes with Python, Ruby, c-sharp and Java so anybody that says that that Nodejs isn’t an enterprise language or enterprise technology at this point is probably full of it.

The Fifth reason to use NodeJs

It’s not new and hip, that it’s no longer a fad there’s so many fads that come and go in the technology world like we don’t know where technology’s headed any given month or a year we don’t really know, we can’t see that but the argument for a long time was that Nodejs wasn’t going to be this all-encompassing thing that everybody jumps on that to replace Python and Ruby. It’s done that to some extent, but it’s not going to completely replace those technologies. However, I think it’s safe to say that Nodejs isn’t some sort of up-and-coming thing anymore, so the fact is, it’s not new and hip, is actually a good thing.

The Sixth reason to use NodeJs

7 reasons to use NodeJs

Node is not a bloated framework. It means that, it does not come with the bells and whistles of a full stack framework.  You can’t compare Node to Python Django or Python flask or Ruby on Rails, it’s nothing like that, it’s it web server technology that you can use a bunch of different frameworks that exist for Nodejs, like Express.

But the fact is that if you don’t need that stuff and you just want a bare-bones Web API like a lot of people tells you that, the go language and Go language is very good at that and I’m sure it is. But, so is Nodejs, and Nodejs has been around a little bit longer and has a larger community, so depending on how slim you need your server-side API to be, Node can be as slim as you need it to be.

An additional feature like templating and things like that, when things get a little bit more bloated and slowed down but you know, node is itself a very bare-bones thing that you get if you’re building just a web server from it.

The Seventh reason to use NodeJs

7 reasons to use NodeJs

the future is lean. JavaScript you know we’ve seen a lot of confusion in the industry about which frameworks and things like that you should be using but the fact that matter one thing, that we don’t want bloated full stack frameworks, because bloated full stack frameworks are slow and they do not built with the modern-day client-side library. like react or angular in mind and the thing you need your server to be lean and efficient, it needs to be serving JSON data so that these newer client-side libraries can then take it and build your UI from it.

JavaScript now is the front, in handling, routing and everything else, so you need a lean mean server-side setup and Nodejs is probably the best option out there. If I compare it to some of these other languages that have been around the block for quite some time, if I compare, I would choose Nodejs over Python, Python – tornado, even though Python tornado is very good that the documentation just isn’t there, the community just isn’t there, Ruby on Rails is way too bloated compared to a server-side language server-side, you know stacked to set up with Nodejs. You might not be able to compare the speed between the two Nodejs, it is just going to be much faster. So the future of web development I think, more with Nodejs than any other older technologies that I just mentioned, but those are my top seven reasons why you would want to use node.js for your next project.
