In the world of enterprises, strong and quick software became a must-have, whether you’re looking for services to use inside the company or you’re offering a product to your audience. Usually, enterprise applications and websites need to handle a lot of users with minimum delay in response and show high performance. Another parameter is time and budget of development: if it’s possible to optimize them both, that’s definitely a win.
So what technology to choose? We believe that Node.js is the most appropriate one for enterprise software. At this point, you may ask: “But why Node.js if we still have good-old PHP and Java?” We will guide you through the ecosystem of this technology, explaining what Node.js is good for and how it works.
What is Node.js?
Advantages of Node.js
Developers all over the world choose to use Node.js because it is very suitable for real-time applications like social media, online gaming, or instant messaging. There is a high demand for this type of apps, and Node.js offers them the following advantages:
- Efficient development: with Node.js, your team can use one language across the entire project. Client-side and back-side developers are able to understand code written by each side without a lot of time needed for explaining any disconnects. Prepared node.js code can also be reused for the general operation from project to project.
- Speed: we already mentioned the V8 engine that powers the code, which allows Node.js code to execute so quickly. Node.js usage only expands over time, and Google keeps investing in support and updates for V8.
- Cross-platform development: it’s possible to develop a cross-platform desktop app along with your web app. With the help of other platforms, you can use some part of the Node.js code for desktop applications without deep expertise in app programming languages.
- Community: Node.js is an open-source technology, meaning that there are a lot of enthusiasts who constantly share new libraries and support the evolution of the language.
Features of Node.js
Asynchronous and Event-Driven
The nature of Node.js is asynchronous with a non-blocking input/output model. It means that while working with one request, Node won’t block the handling of others. It differs dramatically from the opposite synchronous nature of the application.
Synchronous apps usually have multiple threads: each of them is allocated to a new request. So, it works like this: one thread receives a request and queries it from a database. While database processing, the thread is waiting for the result, and sometimes it takes some time. If there is another request simultaneously, another thread will proceed. But if your app has thousands of users? Either they will be forced to wait, or you need to increase the number of servers. Of course, you can switch to asynchronous nature, but it will take more effort.
Node’s single thread handles all the incoming requests. It transfers it to the database but doesn’t wait for the result and goes ahead and processes the next requests. When the result of the requests is prepared, the message is put into the event loop. When Node.js finds out that the request is ready, it uses a callback to deliver it back to the user.
This makes Node.js efficient for data-intensive apps with a constant flow of requests. But when there is a heavy computation request, for example, video encoding or machine learning, the single thread will block all other requests and cause a delay.
Caching helps to improve user experience by temporarily saving the content of web pages closer to the user and speeds the further download. Node.js has various services to improve caching, and that’s an additional point to the high speed of this technology.
Node Package Manager
One of the coolest Node.js benefits is npm, or Node Package Manager. Basically, it’s installed automatically with Node.js and used for downloading (or uploading) ready-made packages from the cloud server. With npm, a developer doesn’t need to reinvent the wheel: the most common tool your application may require were already developed by someone and publicly shared as modules, thanks to the open-source approach of Node.js.
Node.js Usage Statistics
These Node.js benefits make it so attractive for developers all over the world. But if you still have doubts, check these statistics and let the data convince you:
- 43% of Node.js developers use it for building enterprise applications (2018 Node.js User Survey Report);
- At least 1.2% of websites from all Internet use Node.js (W3Tech);
- 56% of users claimed that Node.js reduced development cost (2018 Node.js User Survey Report);
- PayPal states that Node.js decreased its average response time by 35%;
Looks impressive, right?
Why do Enterprises Choose Node.js?
Node.js is one of the most common choices of big corporations. They even created the Node.js Foundation in 2015, counting large-name companies such as IBM, Intel, Microsoft, GoDaddy, and SAP as its members. So what’s so special about Node.js, what does it offer enterprises that make it so unique?
Performance and Scalability
Enterprises are interested in big applications for multiple users. They usually have a long life cycle, therefore regular improvement is necessary to stay relevant and attractive. Scaling is baked into the concept of Node.js from the beginning, providing developers with the power of flexibility.
One of the bottlenecks of Node development is memory and processing limits, but it can be solved with the help of the Node.js Cluster Module. The module allows splitting a single process (workers) into multiple, which will balance the workload over several CPU cores, and that’s how you can increase the availability of scaling and decrease the amount of hardware.
Most enterprise applications have a huge data exchange between the user and database, and every company is in the race for the best user experience. Non-blocking IO and other Node.js features contribute to that by giving the better capacity to handle huge amounts of traffic and speeding the uploading time.
Node.js Success Stories
Due to its features, Node.js is widely used by successful enterprises, including the top companies from Fortune 500. We found a few examples of world-renowned companies that benefit from Node.js.
Another perk of embracing Node.js is that frontend and backend developers became able to understand each other’s code. The communication improved, everyone could detect bugs on both sides of the app which increased the speed of development.
Node.js helped to create a cross-functional team that again could pay more attention to the user experience and needs.
This social network used Node.js to speed up their mobile app, previously built on Ruby on Rails. The engineering team was looking for an easy solution for larger-scale and efficient interaction between API and database, therefore Node.js came in handy.
As a result, LinkedIn was able to decrease the number of servers and hardware for service hosting, wherein traffic capacity was increased.
The biggest space agency on Earth uses Node.js, too! As you can imagine, NASA’s employees operate a huge amount of information every day. It’s also crucial to keep the historical data and have easy access to it at any moment, especially in case of emergencies.
So when in 2013 astronaut Luca Parmitano discovered that his helmet was leaking with water while he was spacewalking, NASA’s engineers needed to access all the info about the spacesuits astronauts were equipped with. And here they faced the problem: the data was scattered across several databases, and it was impossible to collect it quickly. To prevent this from happening again, the agency decided to focus on Node.js enterprise architecture and create a separate cloud database with easy access.
eBay built its ecosystem using Node.js. This technology helps to improve the support of the platform, as a lot of updates are implemented every day. It gave them an opportunity to turn common elements like automation libraries or development tools into Node.js modules, which saves the time of development.
Combining Node.js with a Microservices Pattern
As we already mentioned, Node.js is very efficient in I/O intensive work, meaning it can handle a lot of requests simultaneously, like adding or reading info from a database. It’s also lightweight, and that’s why it’s considered one of the best languages to build a microservice architecture. Microservices are independent, but they are connected via APIs. This is how it works:
Microservices may have different roles, for example, they may be used for:
- payment systems etc.
Microservices are perfect when you need to scale your application: you need to add a new tool and build required connections, but you don’t need to change or update the services already developed.
Building Cross-Functional Teams
There are two approaches to assembling a team: functional and cross-functional. A functional team usually consists of the same specialists, for example, it can be a team of front-end developers or a team of testers. Therefore, a few different teams are working on the project. Another approach means that one team is working on the project, but its members are different specialists: front-end and back-end developers, testers, architects, designers, etc.
A cross-functional team usually creates a product with a better user experience than a functional team. When people with different responsibilities work together, they get an alternative perspective on the project and become invested in the whole production cycle instead of their sole part.
How to hire Node JS Development Team
Choosing to work with a dedicated team for Node development proved to be the most efficient approach for software creation. It saves your time, money, and effort: you get a synchronized group of people who have deep expertise in the required technology pool.
Cooperating with a dedicated team is much faster than hiring an in-house team from scratch: you don’t need to conduct job interviews and test every specialist with tasks, which may take months of precious time. But even if your staff includes tech specialists, a dedicated team may strengthen their effort and offer knowledge of new technologies.
When looking for a qualified Node.js dedicated team, pay attention to the following aspects:
- portfolio and previous cases demonstrating quality of development;
- testimonials and reviews from previous clients on Clutch, GoodFirms, or other directories;
- methodologies and approaches, which determine the flexibility and efficiency of the development.
