Node.js is open-source, but it’s perfect for enterprises too. Take it from Netflix, eBay, PayPal, Groupon, even NASA who use Node.js on a daily basis.
This article will bust the myths about Node.js and enterprises, keep going.
Myth 1. Node.js Isn't Secure
To say the truth, Node.js is one of the most secure environments in the world.
Recently NPM rolled out an enterprise version of its package manager (also known as npmE). The package manager for enterprises lets you run NPM’s infrastructure behind the firewall. It’s like a gatekeeper, letting you filter out all the unwanted packages. Therefore, large companies shouldn’t be concerned about keeping data in the cloud.
With npmE you can bring all your development under one roof. npm Enterprise has a nice infrastructure. Businesses have their own private registry with advanced security features. They can control access to code, quickly detect vulnerabilities and replace the faulty code.
In addition, npmE will notify you about any vulnerable packages early on, during ‘npm install’ phase. This ensures that the faulty packages don’t enter CI/CD pipeline.
In the end, users can always report security bugs in Node.js using Hacker.one. The security experts will then send you guidelines on how to proceed within 48 hours.
Myth 2. Node.js Is Slow
Node.js is pretty fast without any exclusive thread hacks. It handles multiple connections at the same time thanks to its single-threaded, event-driven architecture.
Meanwhile, many web platforms create a new thread whenever a request is made. This uses up your RAM resulting in lower speed. On the other hand, Node.js makes use of the event loop and the callbacks for I/O operations.
Roughly, this model can be compared to the restaurant. The waiter takes your order, gives it back to the chef and proceeds taking orders from other customers. So he doesn’t just wait until the chef cooks your food; he continues to handle other customers’ requests. This is exactly how Node.js works - it can handle thousands of connections at the same time, using resources more effectively.
This is much faster than the typical synchronous and blocking systems. They would create a new thread every time a new request comes in. So, if there are lots of requests, eventually you can run out of threads. These new requests will have to wait, meanwhile your threads will be just doing nothing. So it isn’t as effective as it may seem, right?
Myth 4. Node.js Isn’t Convenient for Java .NET Developers
Node.js might be harder for .NET developers. It just doesn’t let you code in the same convenient manner. But there’s a solution too – try using Nest.js.
The cherry on the top: it lets you see how your application may potentially look like in your personal browser.
Myth 5. Node.js Isn’t Suitable for Building Complex Architecture
That's a huge misconception. Node.js is incredibly efficient when it comes to microservices or serverless architecture. The platform allows you to create highly scalable, robust web apps based on microservices.
Microservices are becoming more and more popular. Thanks to microservices companies can be more agile: you can develop your app unit by unit, in different programming languages, using different frameworks and deploying them independently. For the record - Amazon, Netflix, PayPal have already implemented this.
Meanwhile, monolithic architecture doesn’t let you scale easily. So if your app sees a traffic surge, you will need to upgrade your servers. But in a monolithic environment, everything should be scaled together. So even if just one part of your app can’t handle the load – you need to scale everything, wasting your resources.
This is not the issue for microservices though – you simply need to scale the exact part separately, that’s it.
Myth 6. Node.js Isn’t Convenient for FinTech
Fintech is number-sensitive. The problem is that Node.js is dynamically typed, so such silly things like ‘100' + ’10’ will turn into ‘10010’. Small stuff like this can get pretty annoying. Yet, the issue can be solved pretty easily. All you need to do is just to use the libraries here and here.
What are the Benefits of Using Node.js?
1) Frequent Updates and Support
All these updates make the development game easier, and keep your products in sync with the new tech. What’s more, Node.js promises to maintain any major Node.js release for 18 months since it’s made an LTS version.
Besides, there’s a very large community around Node.js. There are tons of developers that add value to the network each day.
2) Top-Notch Performance
Node Js is asynchronous; it features single-threaded, event-driven architecture. Thus, it can handle tons of requests at the same time. The response time of your app becomes muuuuuuch faster. This saves your resources too – since you don’t have to fork out for advanced hardware.
What’s more, Node.js works well with microservices architecture, and it helps you scale, dramatically.
Case in point: Currently Netflix experiences a sudden traffic surge due to the lockdown: many new users subscribed to the platform and they consume more content. Nevertheless, the company managed to scale quickly, thanks to its microservices architecture and Node.js.
3) Single Package Manager
npm registry comprises over 190,000 modules. It gives developers a chance to use lots of tools and modules in their work. They don’t have to write typical features from scratch, instead, they can use open-source ready-made solutions. So, is it surprising that PayPal reported 100% productivity boost after switching to Node Js?
Large companies might be worried about security. But as we stated above, npm released an enterprise edition too. You can take advantage of private registries and share the code safely w/ your team members.
4) Node Js Is Easy to Adopt
5) JSON Formats
JSON is a run-of-the-mill format for data interchange, it’s everywhere. So it’s pretty great that Node.js makes use of JSON (as opposed to Java objects). Node.js returns the data in JSON, which means that transforming JSON will be fast by default and you won’t need any additional parser for data processing.
Guess it’s clear now that nothing stands between your business and Node.js framework. Actually, it’s the opposite, since Node.js offers tons of gains helping you to boost your performance.
