Internet of things is a network of devices like sensors, beacons, actuators, and any other items embedded with electronics that enables them to send and exchange data through the internet. Generally, IoT systems pass data through devices to servers and from servers to web or mobile applications that process it and display it to users. It may consist of thousands of such devices, which makes it challenging to manage requests and data streams from and between the devices. Node.js is the best choice when working with the internet of things due to its event-driven architecture.

Node.js provides all functionalities for building real-time chat applications. Particularly, Node has a powerful Event API architecture that facilitates implementing all complex scenarios of a chat application of enterprise nature. The best example is socket.io, with it, all you have to do is create a basic live chat, install the socket.io library on the client's server, 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’s event-driven nature provides an out of the box feature of processing real time data for creating amazing data visualizations with charts and graphs responding to the user’s input instantly without the need to reload the page. Node.js development services are the right choice when your web application relies heavily on user input and output of various data types. Leading providers of such solutions often turn to a Node.js development company that can create efficient APIs in Node for web and mobile.

Real-time collaboration applications offer a wide variety of software solutions for co-browsing, project management, video and audio conferencing, application sharing, collaborative editing of documents, and more. Among the most famous collaboration applications, one should mention Slack for group chats and management of remote teams, Trello for project management, and Google Docs for collective editing of documents.

Node.js is excellent for the development of streaming applications thanks to its native Stream API. 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.
