In 2009, NodeJs was developed by a guy called Ryan Dahla and the current version of NodeJs is v16.9.0. Many established tech giant companies and newly created start-ups are using NodeJs framework in their company. Basically for doing all such calculations and processing, this NodeJs framework of JavaScript is used.įor running our web applications outside the client’s browser, NodeJS is basically used as an open-source and cross platform JavaScript runtime environment.For running the server side applications we use this.For building the I/O intensive applications like video streaming sites ,online chatting applications and many other applications, it is used. Whenever a client requests something from the client side of the application what happens is, the request is first sent to the server and then in that server some processing or calculations goes on for the validation of the client side request and after doing all such validation a response is sent to the client side. and for backend databases we use relational or non-relational databases. For backend servers we can use NodeJS, Java, Python, etc. Basically there are three parts of any application, one is Frontend with which the users are interacting, then comes to the backend server and backend database. If we talk about any application then the part with which the user is interacting is basically the frontend of our website whereas there are many things which happen in the background or in the backend of our website.
