Node.js vs Ruby on Rails: Which to Choose
Choosing between Node.js and Ruby on Rails when you select your development platform is a key decision. It will impact the way your project unfolds over time and how much server resources you’ll need. Both languages can support web applications of great complexity, but each has distinct advantages and disadvantages. Knowing these pros and cons will help you pick the optimal solution to fit your intended project.
A Quick Intro to Node.js and Ruby on Rails
What’s the background and purpose of each of these languages? Let’s take a quick look.
Ruby on Rails
Built on the Ruby programming language, Ruby on Rails ( RoR, or sometimes just “Rails”) is a fully-fledged website framework which includes everything you need to complete a website project including the ability to manage logic, routing and applications, all out of the box. These handy tools also include database integration and controllers which makes it easier to facilitate web development on an end to end basis. Popular applications running on RoR include GitHub and AirBnB.
Node.js vs Ruby on Rails: Where Node.js Wins
Node.js is best known for its speed. Partly thanks to a combo of programming centered events and programming which is not synchronised. Plus, input output that avoids blockages. All of which maximises the use of a single processor core and computer memory.
Effectively, Node.js can handle more requests at the same time, and by definition, the workload of many web servers. Node.js allows programs to keep working even the input, output demands when a server is high. Keeping app performance up no matter the load.
One language only
Node.js is also good for scalability
The mix of Node workers and clusters can easily create additional Node.js processes, all depending on the workload. This makes Node.js applications easy to grow. The way Node.js is designed means that what you can do is really only limited by the number of server processors you have access to. Making Node.js a good platform if you’re planning on rolling out enterprise apps.
Points to watch out for with Node.js
Efficiency when operations are CPU intensive
Node.js is great for applications which involve small, frequent and simultaneous requests. However, it can struggle with applications which create high CPU usage in each thread. Because Node.js is single-threaded. If you’re going to manipulate images and video on your server, you may find that Node.js bogs down. There are workarounds. But it adds to development time and cost.
Quality of modules and documentation
Node is flexible but this can be a problem. Sometimes modules are low-quality and the documentation on offer can be short on specs. As the developer, you have a choice of modules with Node.js. And it’s not always obvious which module is best. Choosing a template engine, for example, can take time.
So Node.js is less of an out-of-the-box solution compared to RoR. Modules can be tricky to integrate too, while also being buggy and introducing unexpected behavior for devs. It’s, therefore, key to have an experienced Node.js developer on your team who can help solve issues.
Ruby on Rails vs Node.js: Where Ruby on Rails Wins
Web development best practice
Rails comes with a view to create best practice for web development. The creator intended to make it easy to develop sites according to a set framework which puts convention before configuration. As such, Ruby On Rails ships with every necessary library and module. And they all implement the model, view and controller paradigm. The intention is to make web development as predictable and smooth a process as possible.
Infrastructure that is expansive
RoR’s built for quick site development. So, it includes an integrated web server. Plus, it has a database with generators and scripts. These are powerful and hence make it easy to put together a Rails application. You can automatically put all the necessary bits and pieces a functioning Rails site requires in place. It’s absolutely great for rapid development.
You can easily migrate Rails databases. Because the model that supports the Rails database, ActiveRecord, can easily translate the differences amongst the numerous SQL interactions. Instead of writing out SQL code, users of Rails can use the Rails language to describe changes to database tables.
So, in effect, the schema being created is agnostic of the database in use. Which means you can run your Rails application in many different database environments.
Points to watch out for with Ruby on Rails
Flexibility can be an issue
Often, for every advantage, there is a matching drawback. This is the case with RoR too. Due to Rails creator’s development vision, you may feel restricted with RoR if your particular application is too unique. The Rails platform imposes a lot of authority on the developmental process. So there can come a point where adjusting RoR to fit your requirements takes up a huge amount of your time. Whereas simply starting from scratch would have been quicker.
Performance is not always optimized
Again, a positive point that can also be a negative. Because of the large number of modules in the box, RoR can seemingly bog down when running in the real world. The overall framework is heavier than alternatives, including Node.js. So it’s not so efficient at managing a barrage of requests – typical of many website applications. You can add more server instances, but these use up your memory.
Debugging can be tedious
Because of Ruby on Rails’ complexity and multiple layers, it can be difficult to troubleshoot a Ruby application. Finding an error in the mix can be very time-consuming. So if something goes wrong, perhaps compounded by your application’s custom requirements, you can find Ruby on Rails a very tedious platform to develop on.
How to pick between Node.js and Ruby on Rails
The only thing that’s clear is that neither Node.js nor Ruby on Rails provides a solution ideal for every development situation. But each environment is suited to a specific kind of task. Let’s look at the types of tasks each environment is most appropriate for.
Where Node.js works better than Ruby on Rails
By now you may have gathered that Node.js is great for applications that are real-time. And which handle a lot of concurrent requests. Under these scenarios, data constantly goes between the client and server. These Real-Time Applications (RTAs) include chat apps, applications for collaborating and video conferencing.
Because Node.js is event-based, it’s great for handling these apps. Running on a single page (known as SPAs or Single Page Applications) involves a lot of processing on the client side. The main function for the back-end under these scenarios is to just provision a REST API. Whenever you’re worried about performance and scalability, you should turn to Node.js first before you consider Ruby on Rails.
Where Ruby on Rails is preferable to Node.js
As I said before, Rails is a better solution where your applications are very CPU intensive. And where development needs to happen quickly. Because Node.js is a single-threaded environment, it cannot cope well with handling data such as images and graphics. A computation on a big dataset in Node.js can simply block all the other requests that are coming in. Hence, rendering the advantage of Node.js void.
Second, Rapid Application Development, or RAD, is an important aspect of rolling out websites too. And here, Ruby on Rails is the clear winner. You can have a prototype in short thrift, with little work, when you use Rails. Whereas just starting out on Node.js involves quite a lot of choices. As much as Node.js provides generator scripts to speed up development, it’s simply never as fast as Rails.
When you pick between the two platforms, the main points you should consider are the development speed you need, and the server performance parameters. Are you running lots of simple, concurrent requests through the application? Or more complex, CPU intensive requests? Go with Node.js for concurrency, and Ruby on Rails for CPU intensive applications.
