Node.js vs Swift: What are the differences?

What is Node.js? A platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

What is Swift? An innovative new programming language for Cocoa and Cocoa Touch. Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

Node.js belongs to "Frameworks (Full Stack)" category of the tech stack, while Swift can be primarily classified under "Languages".

"Npm", "Javascript" and "Great libraries" are the key factors why developers consider Node.js; whereas "Ios", "Elegant" and "Not Objective-C" are the primary reasons why Swift is favored.

Node.js and Swift are both open source tools. It seems that Swift with 48.4K GitHub stars and 7.76K forks on GitHub has more adoption than Node.js with 35.5K GitHub stars and 7.78K GitHub forks.

Uber Technologies, Netflix, and Medium are some of the popular companies that use Node.js, whereas Swift is used by Uber Technologies, Slack, and Lyft. Node.js has a broader approval, being mentioned in 4104 company stacks & 4039 developers stacks; compared to Swift, which is listed in 994 company stacks and 541 developer stacks.

Currently, I am a university student, and it is my second last semester with a major in Computer science. I want to start my career in full-stack web development. I know Python with Django + PHP with Laravel, and my focus is on learning MERN stack. I am a little bit confused as to which technology I should choose: Django or Magento or MERN stack.

I suggest you to go with MERN Stack (Mongo,express,react,Node). As you know python and django which is a plus point because you can use python and node as your backend and for front-end use react(easy to learn) and database of your choice.(Mongo or SQL)

Currently working on my company's new saas, the main goal is to manage content and user. I'm familiar with the rails framework and how it is easy to code and deploy. The thing is I'm the only dev on the project, and in terms of the tech stack, there is no preference. However, because Node.js is everywhere and there is enough dev on the market, I am stuck between choosing Rails or Node.js. I don't mind implementing Vue.js or React on the frontend, but I need a solid argument to explain to people that aren't necessarily tech-savvy as to why we should choose Rails over Nodejs.

Node.js

You are probably referring to ruby on rails for web development and nodejs for building the backend. Nodejs has frameworks such as express and next which not only provides a minimal code to build a backend but also gives the flexibility to try and experiment with the framework choices. For example you can have express framework + Passport for OAuth .... etc. The flexibility and the constant improvement of the language provides a good reason to opt for nodejs. Nodejs uses javascript which makes your code uniform when you are working full stack i.e react in front end and nodejs in backend.

Rails API

I'd use the following metaphor to non-technical people. Rails is like a prepackaged toolkit, which can get most of the common tasks done fairly with ease. Whereas, node.js with whatever backend framekwork of choice, is like a DIY toolkit assembled by mix-and-match different tools in a large tool shop. Of course, at times DIY toolkit can do better on specific tasks. Given that you are the only dev on the project, I'd assume that the resource is fairly limited. And looks like you are not building some next-gen super duper fast smart application. So Just go with the prepackaged toolkit then. Rails is a very opinionated framework, there're pros and cons to it. But thanks to that, many of the gems are coded with it in mind. For example, they are all designed with same naming convention. Many will work well together out-of-box, for example devise and cancancan. Besides, many stuff are built in the framework. For example, logging utility, csrf protection, session encryption, etc. Yes, many of those stuff may not be useful or necessary at the beginning of the project life-cycle. However, down the road, there is a good chance you will need some of those. And the moment you realize that you already have it, it's so delightful. In addition, it's usually easier to debug a rails app than a node app in my experience. Personally, the cases where I would pick node.js over rails would be projects either require a) high-performance, or b) certain core functionality that has been implemented by some node packages but not by any ruby gems. In term of performance, node has a clear advantage over any other major web frameworks, except the ones built with go. It's simply a language feature. Node allows developer to easily write code that runs db query, external api calls, or other stuff of that nature in parallel. And that is THE MOST COMMON performance bottleneck of web applications.

Rails is currently a very mature and feature complete framework.

It's the ideal one if you're the only dev for your project because you get so many things already baked-in the framework that you'd only need to deeply care about specific stuff.

I won't say any NodeJS framework isn't good enough but in my experience with NodeJS frameworks you have to code a lot of the things Rails already provides. There's many people in Twitter and IRL asking for a "Rails for JavaScript" framework.

And you know? In the early stages of any project we have to validate it first with real users/customers. With Rails you can get to production real quick and fast.

I'm going to mention some of the features you get from day 1 when you run rails new app_name:

  • File uploading with Active Storage
  • Rich text editor with Action Text
  • Emailing with Action Mailer
  • ORM, migrations, validations with Active Record
  • Web sockets with Action Cable
  • Internationalization
  • Modern frontend stuff with Webpacker

and more.

The JavaScript community is on its moment, growing and gathering more people everyday but the Rails community is also a big one and there's always going to be a Rails developer to hire whenever you're ready to hire someone.

I suggest you to go with Rails because is a good choice, gives you less things to worry about and it's a very good and mature framework.

I hate to admit it, because I loved my time with Rails (and I still love the framework), I have a hard time justifying new Rails applications these days. Core team has made some tragic design decisions, and developers just don't perceive it as being "cool" any more. The latter is a terrible metric for which to base a technology decision, but I think you'll find it more difficult to recruit additional engineers if you choose Ruby on Rails.

Without knowing too much of the details, Node/Express (ideally with Typescript) seems like a better solution here, given you'll be building out the front-end in Vue or React. It might be worth looking at NestJS, as it's the closest I've seen to a well-formed opinionated framework on the Node side of things. We're also fans of Objection ORM.

I hope that's helpful!

I need a solid argument to explain to people that aren't necessarily tech-savvy as to why we should choose Rails over Nodejs

Hi Max, it sounds like that you are proficient in both stacks and probably have a higher expertise in Rails (correct me if I am wrong) and since you are the only dev on a project, a good argument that comes to mind is probably the velocity and maturity (enterprise grade, battle tested in production) that Rails provide with proven success stories in the tech industry such as Airbnb, Stripes, Shopify to name a few. You can also make the argument that Rails is great to run the backend and React+Vue (and nodejs for tooling) is ideal for the front-end development (see or find companies example that use both). You can also build and show a prototype using both and share your experience which could help you find and forge the selling points to those non tech savvy folks, why not.

Eventually, are you going to have other developers on your project? if yes then you will need to take in account, onboarding and ramp up to contribution time when they are hired.

IMHO, I am not a fan of the debate Rails vs Nodejs, they are just tools at the disposal of the developer it's just a matter of figuring out what makes the most sense.

Let me know if you wanna discuss further, happy to help out!

ps: markdown preview on stack share... no good.

Rails has advantages over node.js (specifically express) when working a more complicated backend. While Express has some speed advantages to Rails, this is mitigated if your software is more CPU intensive.

Django

If you are currently not working my first suggestion is to study both the frameworks and get a good grasp of those. If you didn't get confident with Django in the first place you should reconsider going back and study more. Get a video course with some code-along and produce some simple application you can showcase on your interviews. If you already took a course take a different one. Another trainer could be more effective and you could experience something new with different excercises. There are lots of both free and paid courses out there. When you will get confident with Django get your feet wet with Node.js because it surely worth it. Node is very different from Django from some perspective, it looks more like an asynchronous version of Flask to me. Be sure to have a good knowledge of ES6 first, because it will be really useful to understand the Node best practices. Study as much as you can now if you are not working. It will supercharge you for the future...

From my experience of the early startup world, a majority of companies these days use Node.js. Python and Go are the next biggest languages, but significantly smaller than Node.

However, if you're having trouble with the front end aspect of Django, using Node probably won't make that easier for you. You'll have a lot more options between front end frameworks (React, Vue.js, Angular 2) , but they'll definitely take more time to learn than Django's templating system.

Think about whether you want to focus on front end or back end for now, and make a decision from there.

I had the same question myself a few months ago. I finally chose Node.js, and it was one of the best options I did back then. From when I started programming, I always believed that Python was for me the best language, secure and stable. However, it is not flexible for web development, there are more packages & libraries that are built and work only with JavaScript / TypeScript, and the community, resources & support is much bigger. I was also fascinated by the Django ORM, which I still am, & the admin interface. But those are things, that can be replaces by other tools, such as TypeORM, and the admin interface was not needed at all finally for my case. I know understand that Python is not the language that I should use everywhere and every time, but I can say that it is really good for algorithms, computer science, maths, statistics, analytics & AI. To be honest, I chose TypeScript (TS) with Node.js & Express, because it has auto-completion and "strict" code checking. I hope this helps you, and let you take a look at various aspects of choosing a programming language to work with.

Jinja

Jinja is a template rendering engine and you will encounter some sort of template rendering engine in each language. Jinja is a pretty standard tool and almost every language has some sort of Jinja equivalent. Ruby has Liquid, Node has Nunjucks, Java has Jinjava, Go's default templating engine is easy to pick up if you know Jinja, Helm charts are easier to pick if know Jinja . So learning Jinja is a good thing.

We actually initially wrote a lot of networking code in Kotlin but the complexities involved prompted us to try and compile NodeJS for Android and port over all the networking logic to Node and communicate with node over the Java Native Interface.

This turned out to be a great decision considering our battery usage fell by 40% and rate of development increased by a factor of 2.

As a small team, we wanted to pick the framework which allowed us to move quickly. There's no option better than Rails. Not having to solve the fundamentals means we can more quickly build our feature set. No other framework can beat ActiveRecord in terms of integration & ease-of use. To top it all of, there's a lot of attention paid to security in the framework, making almost everything safe-by-default.

Hey guys,

My backend set up is Prisma / GraphQL-Yoga at the moment, and I love it. It's so intuitive to learn and is really neat on the frontend too, however, there were a few gotchas when I was learning! Especially around understanding how it all pieces together (the stack). There isn't a great deal of information out there on exactly how to put into production my set up, which is a backend set up on a Digital Ocean droplet with Prisma/GraphQL Yoga in a Docker Container using Next & Apollo Client on the frontend somewhere else. It's such a niche subject, so I bet only a few hundred people have got a website with this stack in production. Anyway, I wrote a blog post to help those who might need help understanding it. Here it is, hope it helps!

What are some alternatives to Node.js and Swift?
AngularJS
AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.
PHP
Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
JavaScript
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
React
Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

Review of
Swift

The performance of Swift is almost the same as that of C++, which is considered the fastest in algorithm calculation arithmetics. Apple had this idea in mind and worked to improve the speed of Swift. For example, Swift 2.0 has beaten C++ in several computation algorithms, such as Mandelbrot algorithm. Objective-C is slower because it contains C API legacy.

Swift is faster than Objective-C, because it removed the limitations of C language and has been improved with the help of advanced technologies that were unavailable when C was developed. As mentioned by Apple, Swift was originally designed to operate faster.

Despite the fact that languages are different, they both integrate, and work with Cocoa and Cocoa Touch APIs, for all Apple platforms. Therefore, a regular app-user would not recognize the difference in operating speed between Objective-C vs Swift. Speed also depends on a programmer’s level and capabilities, since a slow app can be written in Swift as well.

How developers use Node.js and Swift
MaxCDN uses
Node.js

We decided to move the provisioning process to an API-driven process, and had to decide among a few implementation languages:

  • Go, the server-side language from Google
  • NodeJS, an asynchronous framework in Javascript

We built prototypes in both languages, and decided on NodeJS:

  • NodeJS is asynchronous-by-default, which suited the problem domain. Provisioning is more like “start the job, let me know when you’re done” than a traditional C-style program that’s CPU-bound and needs low-level efficiency.
  • NodeJS acts as an HTTP-based service, so exposing the API was trivial

Getting into the headspace and internalizing the assumptions of a tool helps pick the right one. NodeJS assumes services will be non-blocking/event-driven and HTTP-accessible, which snapped into our scenario perfectly. The new NodeJS architecture resulted in a staggering 95% reduction in processing time: requests went from 7.5 seconds to under a second.

Trello uses
Node.js

The server side of Trello is built in Node.js. We knew we wanted instant propagation of updates, which meant that we needed to be able to hold a lot of open connections, so an event-driven, non-blocking server seemed like a good choice. Node also turned out to be an amazing prototyping tool for a single-page app. The prototype version of the Trello server was really just a library of functions that operated on arrays of Models in the memory of a single Node.js process, and the client simply invoked those functions through a very thin wrapper over a WebSocket. This was a very fast way for us to get started trying things out with Trello and making sure that the design was headed in the right direction. We used the prototype version to manage the development of Trello and other internal projects at Fog Creek.

All backend code is done in node.js

We have a SOA for our systems. It isn't quite Microservices jsut yet, but it does provide domain encapsulation for our systems allowing the leaderboards to fail without affecting the login or education content.

We've written a few internal modules including a very simple api framework.

I ended up picking Node.js because the game client is entirely in JavaScript as well. This choice made it a lot easier for developers to cross borders between being "client side" game developers and "server side" game developers. It also meant that the pool of knowledge/best practices is applicable almost across the company.

Tony Manso uses
Node.js

Node.js is the foundation for the server. Using Express.js for serving up web content, and sockets.io for synchronizing communications between all clients and the server, the entire game runs as Javascript in Node.js.

I don't know how well this will scale if/when I have hundreds of people connected simultaneously, but I suspect that when that time comes, it may be just a matter of increasing the hardware.

As for why I chose Node.js... I just love JavaScript! My code is all original, meaning that I didn't have to inherit anyone's bad Javascript. I'm perfectly capable of creating my own bad Javascript, thank you! Also, npm rocks!

It just like a baby. playground can only use without connect to other library...you can not do a simply refactor of renaming a variable. You can go to definition and find reference, but you can not go to implementation....I should write them on xcode not here basically it is not the fault of swift, but it tightly to it, unless you want to use a notepad to write it.
