The answer to this question is that Node.js can be used as either a front end or back end technology, depending on the use case at hand. This article provides an overview of Node.js and how it can be used in both frontend and backend development scenarios.
What is NodeJS?
In addition to its capabilities as a server-side runtime environment, Node.js can also be utilized to write command line tools and for creating desktop applications. Furthermore, the library of modules available for Node.js makes it simple to broaden its features with custom functionality that meets your specific needs.
Front End Development with NodeJS
Node.js can be employed for both client-side (frontend) development as well as server-side (backend) development. On the client side, developers are able to employ the same language they would use in the backend by writing code with Node.js libraries such as Express or Koa, or with libraries such as React or AngularJS for constructing user interfaces (UIs). This makes it easier for developers to move between backend and frontend development without having to learn different languages or technologies for each one.
Furthermore, because Node.js can be used to write command line tools, developers are able to automate tasks that would normally require manual processes when setting up their development environments or deploying their applications to production servers, making the process easier and more efficient overall.
Back End Development with NodeJS
When it comes to server-side development, Node.js stands out due its asynchronous nature and non-blocking I/O API which allows it handle multiple requests simultaneously without having to wait for responses from external services such as databases or other web services before responding itself. This makes it suitable for processing real time data such as chat messages or streaming data from IoT devices in real time scenarios where speed is essential for providing a good user experience and meeting business goals.
In addition, since Node.js is open source, there are many frameworks available that make developing server side applications more straightforward than ever before such as Express JS or Sails JS which take care of many of the tedious configuration tasks associated with building modern web applications such as routing requests and setting up databases connections quickly so that developers can focus on building the application itself instead of managing infrastructure related tasks.
