Node.JS is a cross-platform runtime environment. It is open source, and the environment is meant for developing networking and server-side apps. NodeJS App is the powerful itself to run across Windows, OSX and Linux platforms within the Node.JS runtime. NodeJS web development companies can use an extensive JS module library simplifying the entire developmental process.
Key Features of NodeJS:
- Event Driven and Asynchronous– All Node.JS library APIs are non-blocking or are asynchronous. Servers running on NodeJS backend do not wait for APIs to return data and move to the next API. Node.JS employs an event notification mechanism to do the needful from an earlier API call.
- Single Thread Highly Scalable Architecture- JS adopts the single-threaded model along with event looping. Such an event mechanism prevents blocks in server response contributing to its scalability. The typical server creates several limited threads to handle requests. Through its single threaded model Node.JS can manage a far larger number of requests than its competitors like Apache HTTP Server.
- Non-Buffering –JS apps simply don’t buffer data and output the same in chunks.
- License − The MIT license governs the use and development of Node.JS
NodeJS Development consideration:
When you need to develop real-time apps
NodeJS web development companies hail the technology for its performance and speed. A real-time communication app is the archetypal Node.JS use case. Node.JS comes into its own from its capability to handle heavy traffic consisting of several short messages and chatrooms with the need to show the real-time content to many users.
Creating IoT apps
The synergy needs of IoT applications development is arguably best met by Node.JS. Not only does Node.JS provide the speed and power necessary to manage large data flows, but further NodeJS web development companies and developers can also integrate it with different IoT protocols like WebSocket and MQTT with relative ease.
Lastly, the technology comes with the Node Package Manager component which comes built-in with several helpful IoT modules. By using them it is quite possible to create even significantly ambitious IoT projects.
It comes with a lot of collaborative tools
The superior handling of real-time flow processing was one of the primary reasons why the popular project management and collaboration tool, Trello used Node.JS for developing its app. The app became more effective due to the event-driven, non-blocking features of Node.JS. The tech is perfectly suited for apps that need instantaneous updates like most online documentation and collaboration tools.
Create data streaming applications
The streaming ability of Node.JS is essential for video/audio streaming apps. Node.JS comes with built-in modules that help data streaming. Further, the data streams involved can be both readable and writable. The leading video streaming platform Netflix uses Node.JS.
Need scalable apps
Node.JS can deal with high peak loads with relative ease. Its scalability is a clear winner when high loads are involved. Uber used the platform to develop its app and Node.JS has remained the reliable platform for the business as it extended to the four corners of the world. Even peak demands of holidays could not deter Node.JS and Uber.
When require hardware programming
When building microservices
Node.JS is not just yet another programming language through which you can build a microservice, it is one of the best options at hand for that purpose. The Node.JS architecture lets it assign I/O tasks to internal threads without keeping the main thread blocked. Further, the ease with which one can decouple due to the event driven Node.JS architecture makes it a clear favourite for creating microservices.
