What is Node.js?
Node.js is a JavaScript runtime environment with a formidable ecosystem and is built on Chrome’s V8 JavaScript engine. It is a fast, lightweight, scalable, and efficient environment. Node.js is the world’s largest ecosystem of open source libraries with outstanding features such as an event-driven model, serverless architecture, and many more.Node.js development trends in 2020 maximize the value you get out of this framework. Therefore, Node.js is currently the first choice of 98% of the Fortune 500 companies. Not just that, it also tops the list of the most used frameworks and libraries.
Types of applications you can build with Node.js
Node.js offers great advantages for a wide range of applications. Following are the top 6 kinds of applications you can build using Node.js:1. Internet of Things (IoT)
Why use Node.js for IoT
The biggest reason to choose Node.js for such networks is its remarkable ability to process multiple concurrent requests. Node.js has an event-driven architecture and facilitates asynchronous data processing. As a result, the servers of Node.js do not get blocked and the data requests are processed conveniently.Secondly, Node.js serves as a smooth and efficient application layer between the IoT devices and the databases that store the information emitted by these devices.Moreover, Node.js has minimal memory requirements. As a result, node.js developers can easily integrate it with single-board controllers like Arduino. These are commonly used in the creation of digital devices that constitute an IoT system.2. Real-Time Chat Apps
Why build real-time chat apps with Node.js
Node.js has an Event API that allows developers to work in an event-driven approach with any data. This functionality greatly helps in implementing server-side events and push notifications. Both of these features are frequently used in real-time communication applications.The event-driven structure of Node.js also allows it to establish and maintain collaboration with WebSockets. A web socket is crucial for a quick exchange of messages between the client and server via one open connection. Thus, Node.js plays a hugely beneficial role in real-time chat apps.Node.js is capable of carrying out real-time messaging with lower latency and faster data transfer if you choose to install the WebSockets on the server-side as well as on the client-side.3. Single-Page Applications (SPAs)
Why build SPA with Node.js
Node.js is a robust runtime environment that can handle asynchronous calls and heavy I/O workloads with great efficiency. This makes it well-suited for complex SPAs.The event loop characteristic of Node.js authorizes it to delay multiple concurrent requests from the client. Thus, it ensures a subtle and consistent transition accompanied by seamless data updates.Lastly, Node.js is written in the same language (JavaScript) as used to build SPAs. This makes the work of developers quite simple because they can use the same language and data structure on the server and the client-side. In turn, the development process speeds up and enhances the maintainability of the SPAs.4. Real-Time Collaboration Tools
Why build real-time apps with Node.js
Real-time collaboration apps present a case similar to that of real-time chats. Node.js asynchronous and event-based architecture provides a great edge in building these apps.Collaboration apps generate multiple events and I/O requests simultaneously. For example, a group of students can edit the same document or even the same paragraph of that document. In this scenario, Node.js utilizes the WebSockets and Event API to make sure that the requests and data submitted by multiple users do not hang the server and that all the server-side data is delivered to the client without any delay.The push notifications given by Node.js promptly update the collaboration environment. This is to ensure that all the users have a single and coherent view of the application.5. Streaming Apps
Why build streaming apps with Node.js
An inherent feature of Node.js, Stream API, makes it an excellent choice for designing such streaming apps.Moreover, Node.js possesses a comprehensive interface of readable and writable streams that can be controlled and processed effectively.6. Apps with microservices architecture
Why use Node.js for microservices architecture
Native Node.js frameworks like Koa and Express which enable you to create some highly flexible microservices modules.When integrated with Docker, Node.js contains microservices in their respective containers in a clean, well-differentiated manner. As a result, there is little chance of microservices hampering one another’s functionalities.Node.js is extremely lightweight and has minimal resource requirements. So building microservices with Node.js makes applications efficient and quickly deployable.Top Famous Apps Built With Node.js
Because of its advanced features and limited resource requirements, a large number of corporate giants have adopted Node.js application development. So here is a list of 5 Node.js applications built by famous companies.1. Node.js in PayPal
PayPal, the world’s most popular online payment platform, decided to use Node.js in its application in 2013. Having to write the front end and the back end codes with different languages was the main challenge PayPal’s engineering team was facing. Node.js was the only way for them to solve this problem. Jeff Harrell, Director of Engineering at Paypal, explains,“Node.js helps us solve this by enabling both the browser and server applications to be written in JavaScript. It unifies our engineering specialties into one team which allows us to understand and react to our users’ needs at any level in the technology stack.”
2. Node.js in LinkedIn
The world-famous professional networking platform LinkedIn used to run its back-end on Ruby on Rails. However, the company decided to use Node.js for its mobile-app backend in 2011.As a result, the LinkedIn app became 20% faster with the help of Node.js. Kiran Prasad, VP of Product at LinkedIn, elaborated,“One reason was the scale. The second is, if you look at Node, the thing it’s best at doing is talking to other services. The mobile app has to talk to our platform API and database. We’re not doing massive data analytics. Node showed us huge performance gains compared to what we were using before, which was Ruby on Rails.”
3. Node.js in Netflix
The global favorite video streaming app Netflix chose to build their entire user interface using Node.js. It sped up the development process manifolds. Moreover, Node.js also reduced the app startup time by over 70%.Kristofer Baxter, the then UI engineering manager at Netflix, wrote in a blog,“Three large pain points shaped our new Node.js architecture:
Context switching between languages was not ideal.
Enhancement of markup required too much direct coupling between server-only code generating markup and the client-only code enhancing it.
We’d rather generate all our markup using the same API.”
4. Node.js in Uber
Uber, one of the largest on-demand apps, needed a feasible solution for handling millions of data requests daily. Node.js, with its exceptional data processing features, was chosen by Uber as one of the app’s leading technologies.Matt Ranney, a senior staff engineer at Uber, had shared,“One of the things that make Node.js uniquely suited to running in production is that you can inspect and change a program without restarting it. So very few other languages offer that capability. Not a lot of people seem to know that ability exists, but indeed you can inspect and even change your program while it’s running without restarting it.”
5. Node.js in GoDaddy
A leading web hosting and domain registrar company, GoDaddy migrated the back end of its app to a full-fledged Node.js infrastructure. With the help of Node.js, GoDaddy app was able to reduce its dependence on hardware to a great extent. Antonio Silveira, the then VP of engineering at GoDaddy, had written in a statement,“We are now using about 10x fewer servers to host our customer websites and we reduced the Time To First Byte (TTFB) considerably from ~60ms to something around ~12ms. Performance is a key differentiator when we talk about web applications, including a better position in Google’s search results.”
The Bottom Line
Node.js is efficient, runs on JavaScript, and speeds up the development process. So from SPA to IoT, there are many different kinds of applications you can build with Node.js.
