Nodejs Apps

10+ Reputed Node.js App Examples and Those You’ve Likely Never Heard of

In 2009, Node.js started a successful revolution of shifting JavaScript to the back-end. Today, this JS runtime environment tempts startups and sustainable businesses to build their digital products with it. Some of these Node.js app examples are commonly known, while others are underdogs still striving to reach a global user base.

Examples of Nodejs Apps

Types of apps that can be built with Node.js

Before we get to the main course, let’s learn what a typical Node.js application looks like. The technology is known for the capability to process multiple concurrent events in a single thread. That characteristic is crucial for projects associated with data-heavy workloads. At the same time, apps that require CPU-intensive tasks are beyond Node.js’ scope that we’ve already learned when compared Python vs. Ruby vs. Node.js. Having weighed all the benefits and downsides of the JS runtime environment, we get a set of particular applications best approached with Node.

Single-page applications

Today, you may encounter single-page applications (SPAs) in the form of different text or drawing tools, mail/networking solutions, etc. This type of apps can benefit from Node’s asynchronous data flow. It features a seamless data update due to the event loop. As a result, the page receives new data without the need to refresh. LinkedIn is a good example of a SPA created with Node.js.

Real-time applications

Versatile PM solutions, collaborative services, video conferencing, document sharing, and online communication (chats) tools are good places to implement real-time applications (RTAs). This type of app has numerous users that perform heavy I/O operations. The risk of overloading the server is extremely high. However, Node makes the collaboration environment update seamlessly due to Event API and WebSockets. Trello is an example of a Node.js application where real-time collaboration pattern is implemented.

Internet of Things

The typical structure of an IoT system has data transfer in the direction device-server-app where the last element processes and shows data to users. And the number of such devices can be immense. Node.js allows you to handle an ocean of concurrent requests sent by myriads of devices. The already mentioned attributes of the technology (asynchronous processing and event-driven architecture) allow the runtime environment to function as an app layer between databases and devices. As an example, we can take Monet, an IoT Energy Management Platform based on MongoDB, which has leveraged the benefits of Node.js for several years.

Streaming apps

Node’s native Stream API is the reason why technology is a perfect choice for building streaming applications. The technology enables you to transmit parts of the code without closing the connection if other components are required to download. No caching or temporary data is attached. Node provides an open connection for the app data streaming.

Why startups choose Node.js

Node.js possesses all the typical benefits of a popular tech stack for web development, like open source or expansive ecosystem. Nevertheless, it does draw the attention of startupers searching for a reliable and usable tool to digitize their ideas. It’s not magic – the technology simply has several key strengths, which allow it to outcompete other market players.

Practicability

One of the runtime’s killer-features is the shareability of JS on both sides of the fence. It means that you can use Node.js for backend and frontend as well. In practice, this means an acceleration in development speed and a reduction of server-side maintainers. And don’t forget about the code – it will be significantly smaller in scope. A bunch of tools available within the node package manager (NPM) also contribute to the development cycle optimization.

Microservices

Despite the settled trend of using monolithic architecture in app development, microservices architecture is planning to get back on the throne. The idea of splitting an app into small services is highly appealing to startups, not to mention industry giants like PayPal or Netflix. In that context, Node.js is a perfect solution to support the best of microservices due to event-driven I/O model and a plethora of ready-to-use modules available through NPM.

Mobile compatibility

Don’t believe posts and claims you may see about the direct mobile app building capabilities of the runtime. If you want to build a mobile app with Node.js, there are two ways to accomplish this. The first one is to opt for a framework like Ionic oriented at building hybrid apps. The second way is to go cross-platform with React Native. We’ve even made a review of Ionic vs. React Native to facilitate your choice of tech stack. The role of Node.js is limited to keeping the app’s business logic on the server. Using specialized frameworks like Angular), you’ll be able to run JavaScript on the client side to achieve performance close to native applications.
