The top 5 reasons you should look to Node.js for your next project
There isn’t a single enterprise today who couldn’t benefit from maximising their agility and responsiveness to market conditions. But for organisations whose technology infrastructure still rests on slow monolithic apps riddled with technical debt, that agility is hard to achieve.
So we thought it was time to reiterate the benefits of Node.js for those who still haven’t made the jump, while not forgetting that there’s no single silver bullet and just switching languages is never enough.
I’m sure many regular readers of the NearForm blog are wondering why we’re doing a post about adopting Node.js in 2019. Particularly given that some of us have been using it in production since 2011.
The reality is that the vast majority of software out there isn’t Node.js and all of the problems of legacy stacks continue to grow.
So let’s dive straight into the top 5 reasons you should look to Node.js for your next project.
If that title sounds familiar, we’ve got a fantastic e-book on the same topic that you may feel an overwhelming temptation to download after reading this blog.
But first: let’s look at those benefits, starting with my favourite:
1. Get apps to market faster
This has been the number one reason since the start of Node.js.
Developers are simply more productive with it.
When a competitor bank is releasing web app updates daily whilst you are on a 6-month cycle, you just can’t compete.
This is about far more than the language, it’s also about the 700,000 Node.js modules on NPM. Your developers can focus on building high-value business logic instead of generic boilerplate.
Is all the code on NPM of high quality?
Of course not. But for every bad module, there are 10 good ones which can do the job better.
Concerned about bad actors or security holes in packages?
Look at fantastic services like Snyk to protect you.
We have seen a huge increase in the number of Fullstack developers who can seamlessly move between Front-End and Back-End development as their projects evolve.
But equally important, both Front-End and Back-End developers have a much stronger understanding of each other’s challenges and can work more seamlessly as integrated teams when appropriate.
They achieved goals of lowering costs and removing duplication of work and systems.
“NearForm has an extremely strong competency in Node.js, and that was a big selling point for Condé Nast International. Node.js was ideal for this engagement: whether you’re looking at the front-end or the back-end engineering, it gives you increased flexibility” David Thorpe, Engineering Manager at Condé Nast International
2. Raw Performance
No end-customer wants to be kept waiting for a sluggish website or mobile app.
We have seen time and again that you can deliver more performant back-end services more quickly with Node.js.
Not only that, but it’s getting faster. According to the 2018 Node.js Foundation User Survey Report, it is continuing to have a positive impact on many users – primarily through increased productivity and satisfaction, reduced development costs and increased app performance.
Node.js’s programming model has continued to deliver the goods in terms of throughput and memory usage for high volume back-ends.
Node.js powers the backend for two of the biggest online marketplaces – eBay and AliExpress – a testament to its speed and reliability. And the addition of features like promises and async/await has made it much more approachable for traditional developers.
From a business perspective, higher performance means lower cost.
We’ve helped many companies over the years, highlighting common pitfalls and programming mistakes, and helping them achieve optimum performance.
“NearForm’s training has helped us to dramatically improve performance in one of our key customer-facing applications. Now we know where, why and how to target potential issues.” Robin Glen, Senior Developer, Net-A-Porter
With free open source tools like Node Clinic, designed and built by NearForm, teams of developers can identify and diagnose problems in their code which is an essential part of the journey toward highly performant applications.
3. Modern architectures and scalability
We’ve already mentioned that Node.js provides a quick startup time, low resource consumption and high performance.
It’s these features that make it perfect for supporting the new generation of apps which leverage microservices and are built to run in the cloud.
Microservices enable separate teams to develop, maintain and deploy each part of an application independently.
Interaction points between each of those parts are clearly defined through APIs over the network, and Node.js excels in ensuring that the communication among all those parts of the application is super fast.
So you already know that the ready-made modules in the Node.js ecosystem let you get to market faster, but what about having the Node.js skills in-house?
Many of the world’s most meteoric and disruptive companies have scaled globally, fast, and continue to innovate at impressive rates, thanks to their foundations in Node.js.
According to the 2018 Node.js Survey of more than 1,600 developers and development management, 68% cited Node.js as increasing developer productivity.
At Moody’s, with whom we worked to help migrate away from a .NET architecture to Node.js, developers’ productivity increased significantly, with the iterative build time (where developers change and re-test their code) reduced by 70 per cent.
With the introduction of a CI/CD environment, they have better visibility of the changes in the code and can be tested immediately.
Even if your developers haven’t used Node.js before, that’s not a deal-breaker: about half of the respondents in the 2018 Node.js survey said that it was generally easy to learn Node.js, while 62% cited increased developer satisfaction using Node.js.
Don’t underestimate the importance of developer satisfaction: happy developers aren’t just productive, they’re also more likely to stay with you, a big advantage in a competitive market for skills.
5. The power of community and open source
Open Source software and the philosophy of code reuse have become central, mainstream concepts in modern software development.
The sheer power of numbers in Open Source communities means that they become self-cleansing, with no greater chance of impactful vulnerabilities than in proprietary software.
The governance model that oversees collaboration between individuals in open source is also proven one, with Node.js improving both its quality and velocity when it was released from corporate control.
A perfect example of open source building on open source is Fastify, the fast low-overhead web framework written by NearForm’s Matteo Collina together with Tomas Della Vedova.
Fastify is powering a large ecosystem of organisations and products including such charitable projects as Hospitalrun.io.
The open-source community’s creativity and productivity has also been paid homage by the InnerSource movement, where innovative companies adopt a similar development model for their in-house software development, with a focus on code reuse.
Node.js and eyes on the prize of rapid application development
It’s no secret that the CTOs inside even some of the world’s most conservative industries and organizations are looking to transition to a more agile way of working, moving away from traditional waterfall software development, embracing microservices, and generally evolving how they build, deploy, maintain and update their code.
They’ve recognized the power and permanence of the open source movement, as well as the proven ability of Node.js, microservices and cloud-native architectures to deliver high-performance, fast-to-market applications that let their technology teams deliver more effectively on business goals.
We’re seeing this evolution every day at NearForm, in our interactions with enterprises.
It’s such an exciting time, as there seems to be a general, board-level recognition that enterprises can achieve a new and permanent improvement in their competitiveness and agility by transitioning to newer methods and tools.
And for organizations in some of the world’s most competitive sectors, that means everything.
