Node.js can be used for different purposes – here are some areas where it excels in performance:
The most obvious advantage of Node.js as a back-end for such networks is its ability to process multiple concurrent requests and events emitted by thousands or even millions of devices on the network. The avalanche of requests and data coming from IoT devices does not block Node.js servers thanks to their event-driven architecture and asynchronous processing suitable for I/O-heavy operations on the IoT network.
This makes Node.js fast as an application layer between these devices and databases used to store data originating from them.
IoT developers working in data-intensive scenarios can leverage the low resource requirements of Node.js. Low memory requirements allow for the easy integration of Node.js as software into single-board controllers such as Arduino, widely used for building digital devices that make up IoT systems.
Finally, the Node community has been an early adopter of the IoT technology, creating over 80 packages for Arduino controllers and multiple packages for the Pebble and Fitbit wearable devices widely used in IoT systems.
Real-time chats can take the form of one-to-one or one-to-many group chats built on instant messaging (IM) or Internet Relay Chat (IRC) technologies.
Node.js provides all basic functionalities for building real-time chats of any complexity. In particular, Node has a powerful Event API that facilitates creating certain kinds of objects (“emitters”) that periodically emit named events “listened” by event handlers. Thanks to this functionality, Node.js makes it easy to implement server-side events and push notifications widely used in instant messaging and other real-time applications.
Node’s event-based architecture also works well with the WebSockets protocol that facilitates a fast two-way exchange of messages between the client and the server via one open connection. By installing WebSockets libraries on the server and the client side, you can implement real-time messaging that has lower overheads and latency, and faster data transfer than most other, more conventional, solutions.
In Node, you have excellent support for WebSockets via such libraries as socket.io, ws, or websocket-node, thanks to which you can easily deploy efficient real-time chats and applications. With socket.io, for example, all you have to do to create a basic live chat is to install the socket.io library on the server and the client, and create event emitters and broadcasters that will push messages across the WebSockets open connection – this basic functionality can be achieved with just a few lines of code.
Node.js is a great fit for SPAs thanks to its efficient handling of asynchronous calls and heavy I/O workloads characteristic of these applications. Node.js’s event loop allows to “delay” multiple concurrent requests from the client, which ensures smooth transitions between views and seamless data updates. Also, Node.js works well with data-driven SPAs, where the server acts as a backend that provides data to the client whereas the client does all the HTML rendering.
With such framework as Express available via the NPM repository, you can turn Node.js into a REST API streaming data and services from specific routes. Such approach helps reduce the server’s load while ensuring API sharing across different applications and environments. In this scenario, Node.js would only return the index page (index.html) while data would be sent via REST interfaces and controllers implemented server-side. From the design point of view, such approach will ensure the clear separation of concerns (SoC) between models, controllers, and views with all data-related services implemented server-side.
As in the case of the real-time chats, Node’s asynchronous and event-based architecture is a great fit for collaboration apps. In these applications, many events and I/O requests occur concurrently. For example, several users can edit the same paragraph, comment, post messages, and attach media. Changes to one piece of content might be applied only after a cascade of events, where each step depends on the previous one.
Node’s WebSockets and Event API will ensure that heavy I/O operations performed by many users do not make the server hang and that all server-side events and data are sent back to the client on time. By emitting push notifications to the client, Node.js will also instantly update the collaboration environment so that all users have a single and coherent representation of the application. This is precisely the reason why the team of the project management application Trello uses the Node.js stack.
The engineering team of Trello decided that Node.js would be great to instantly propagate a lot of updates and hold a lot of open connections, thanks to its event-driven and non-blocking architecture. Among other real-time collaboration apps built on Node.js, we should also mention Yammer, a freemium social networking service facilitating private communication in enterprises.
Node.js is excellent for the development of streaming applications thanks to its native Stream API. In particular, Node.js has an interface of readable and writable streams that can be processed and monitored very efficiently. Stream instances are basically Unix pipes that allow transmitting parts of the app’s executable code to the local machine while keeping a connection open for new components to download on demand.
Streams allow users to pipe requests to each other, and stream data directly to its final destination. As a bonus, streams do not require caching and temporary data – just an open connection to stream application data from one place to another.
Node.js is an excellent solution for developing microservices and creating easy-to-use APIs to connect them. In particular, the Node.js repository features Express and Koa frameworks, which make it easy to mount several server instances for each microservice and design routing addresses for them. Node.js with Express allows for creating highly flexible modules responsible for specific parts of your application.
In addition, Node.js can be easily integrated with Docker and will thus allow you to encapsulate microservices in hermetic containers to avoid any conflicts between the application development environments used in each of them. Using Node.js for microservices also benefits from Node’s lightweight requirements. Node.js with microservices significantly reduces application deployment time and enhances efficiency, maintainability, and scalability of your applications. Microservices architecture also helps manage the division of labor in your engineering teams efficiently, enabling them to work on specific tasks without affecting other parts of your application.

What is Node.js and how can it help my business?Here are answers to some of the most common questions asked by our clients: Let’s work together!
Depending on the technology you are building the app with, the way your development team will work will be different.
The first thing to consider is the time scope of your project. In the long run, Node.js offers relatively low costs of development. Your initial budget will be bigger in comparison to Ruby on Rails, for instance, but with the app’s expansion, scale, new features, and further maintenance, the costs will drop and the development time will be shorter. That’s why it’s more efficient to build a demo or an MVP and a prototype your application with Ruby on Rails. That said, with RoR, the costs will grow more rapidly with time.
Node.js is an unopinionated environment, which means that it comes with few guidelines. Developers need to pick and write solutions on their own. Therefore, at the start of the project, their experience and knowledge about different frameworks should be more extensive than in the case of RoR projects, where many things will be predefined at the get-go.
Finally, you should consider that with the growing popularity of Node.js, there is a rising demand for skilled and experienced developers, which will make finding members of your team more difficult. You should consider that, if you are planning to scale your application in the near future.
If you want to hire more devs for your team, specify the recruitment needs and plan it way ahead so that the lack of coders won’t hamper your work.
An e-commerce platform is a complex system from a technical perspective.
Node.js supports multitasking by giving better outcomes with lower costs. Comparing it to - say - PHP, it’s way more convenient. As the buyer's journey at an e-commerce store involves numerous operations, such as adding things to the basket, changing product features, choosing payments etc., it’s crucial from the performance viewpoint that the technology serve such tasks efficiently. And Node.js effectively handles different operations conducted at the same time, which makes it a good choice for e-commerce.
Node.js enables quick scalability. In a short period, your e-commerce store can grow substantially. It is an important factor to consider when choosing the technology. Node has an inbuilt mechanism that helps to manage scalability and adjust it to your individual needs.
The Node.js community is a very active and vibrant group of developers who contribute to the constant improvement of Node.js. Thanks to their cooperation, the framework is well-documented, up-to-date and continuously supported, which makes the development much easier and faster. They produce a ton of ready solutions, codes in Github, plugins, modules and many more possibilities. In addition, if a problem pops up, chances are you already have the answer on StackOverflow.
Node.js comes with a great deal of packages that can be easily implemented in your app. That way, developers don’t need to write everything from scratch but can leverage reliable open-source solutions. It significantly increases the speed of development. There are great packages available for e-commerce too.
Finally, with no technological diversity recruiting new people in case of scaling up won’t be a problem.
It offers many benefits for building applications such as real-time collaboration tools, streaming apps, chats, or Internet-of-Things apps. Node.js requires a slightly different approach and poses different challenges when it comes to maintenance.
Learning where you can find the biggest problems and knowing the right solutions is crucial to your app’s success:
Node.js doesn’t provide any specific convention for developing the application. Frameworks that use Node.js are mostly unopinionated, meaning that they don’t give you any specific guidelines for the way code should be written.
That’s why each application requires an individual approach and, as a result, more experienced programmers who have worked out good processes for developing and maintaining code internally.
Many problems with Node.js stem from the lack of good practices. The open-source community is very active and offers plenty of ways of building applications. Having too many options however, could be a problem for unexperienced developers and could lead to application structure incongruency.
The ecosystem is still relatively immature. Implementing well tested design patterns borrowed from other more traditional environments like Java is crucial for later code maintenance.
Node.js is a single-threaded process, which makes scaling a little bit more complicated. Developing more complex applications with CPU/MEM-heavy computations might require dividing it into smaller microservices that handle different operations.
When architecting a performant and scalable Node.js application, keep in mind it should be relatively small and stateless. Recent years have brought development in the area in the form of different architectural approaches such as the aforementioned microservices or serverless as well as Node.js threading support (still in the experimental form, but they should be a regular feature in Node v12)
Documentation is crucial to every IT project – it gives you an idea of how the app works. It tells developers what the main components are, how they relate to each other, and what the main purpose of the application is.
It provides explanations as to why certain solutions, especially the less obvious ones, were applied. Poor documentation will very likely extend the development time, and make the whole process more difficult. It can expose the application to problems with performance and inhibit the implementation of new features.
