Accelerate Isomorphic Web Application Development
A Component of MEAN Stack
The developers can further accelerate isomorphic web application development by using NodeJS as a core component of MEAN stack. MEAN stack is the acronym for its four open source components – MongoDB, ExpressJS, NodeJS, and AngularJS. AngularJS simplifies client-side development by allowing programmers to use HTML as a templating language. At the same time, MongoDB is a modern and non-relational database and ExpressJS comes with features to simplify the development of web applications and APIs. The open source components of MEAN stack further help small businesses and startups to curtail web development cost significantly.
Supports Asynchronous Programming
NodeJS is designed with a non-blocking and event-driven I/O module. The I/O module keeps the cross-platform runtime environment lightweight and extensible. Also, NodeJS performs I/O operations through a single-threaded event loop. While executing code, NodeJS send the asynchronous tasks to the single-threaded event loop and keep executing the remaining code. Once the asynchronous tasks are executed the event loop returns to the task. Hence, it becomes easier for developers to improve web applications’ performance and user experience by processing a large number of requests simultaneously and efficiently.
Facilitates File Streaming
The non-blocking I/O model further makes it easier for programmers to accelerate streaming of files from the file system. The web developers can even use the model to read and write the streams directly to HTTP and WebSockets. Hence, it becomes easier for them to reduce the time required to stream audio and video files. They can even accelerate transcode audio or video processing by following some simple programming hacks. For instance, the developers can easily display the audio or video output in real-time to users by shifting stdout from the web server to the web browser by using WebSockets.
Real-Time and Multi-User Application Development
As noted earlier, web developers can leverage NodeJS to build a variety of applications efficiently. But NodeJS is currently being used by web developers for building complex real-time chatting, gaming, and communication applications. NodeJS simplifies real-time application development by allowing programmers to use WebSockets as a two-way communication channel between the clients and web servers. WebSockets further speeds up client-server communication without putting additional overhead on HTTP. The loop used by NodeJS further enables programmers to build multi-user applications
Easy to Scale and Extend
Large Repository of Packages and Modules
NodeJS enables web developers to take advantage of a large and robust ecosystem of open source libraries – Node Package Manager (npm). The developers even have the option to use npm in a number of ways. They can use npm as an online repository to search and find relevant NodeJS packages and modules. At the same time, they can even use rpm as a robust command line utility to install, update, and uninstall various NodeJS packages and modules efficiently.
