It spins around assets where each part is a component and an asset is gotten to by a common interface utilizing HTTP standard strategies. REST was firstly presented by Roy Fielding in 2000.  In REST architecture, a REST Server just gives access to assets and REST client gets to and modifies the assets. Here every asset is recognized by URIs/worldwide IDs. REST utilizes different representations to represent an asset like text, JSON, XML. JSON is the most famous one. The following four HTTP methods are commonly utilized in REST-based architecture. GET         - Provide read-only access to a resource.

Presented by TJ Holowaychuk in 2010 and propelled by Sinatra software, Express is a lightweight framework with complete in-assembled application features.  Express.js is a standard server for Node.js and back-end parts of the MEAN stack. Express JS Manages: Routing Session HTTP Requests Error Handling It removes the development time of the developers and helps in conveying effective and fast applications. Express is anything but easy to modify and configure and can be easily associated with the database like MongoDB, Redis, MySQL. As Express.js is written in JavaScript, it is an exceptionally simple language to learn and manipulate.

Getting Started with React JS

React Components A Component is considered as the main building block of a React application. It makes the undertaking of building UIs a lot simpler. Every part exists in a similar space, yet they work independently from each other and merge all in a parent component, which will be the last UI of your application.  Each React component have their own structure, strategies just as APIs. They can be reusable according to your needs. For better understanding, consider the whole UI as a tree. Here, the root is the beginning component, and every one of the other pieces becomes branches, which are additionally partitioned into sub-branches. In ReactJS, we have primarily two sorts of components. They are  Functional Components  Class Components Component Life Cycle In ReactJS, each component creation process includes different lifecycle strategies. These lifecycle methods are named as the segment's lifecycle. These lifecycle methods are not extremely complex and called

But what does that mean?   Node JS runtime environment includes everything that we want to execute a program written in JavaScript. Node JS came into existence intending to create real-time websites with WebSockets. It is an open-source, free, cross-platform runtime environment for developing server-side and networking applications.      Why Should I Use Node JS? Extremely Fast Node JS is created on Google Chrome's JavaScript Engine(V8 Engine). So in code execution, its library is really fast. I/O is Event-Driven and Asynchronous All APIs of the Node JS library are asynchronous. Because of that Node JS based server never waits for an API to return data. The server goes to the next API after calling it and a Node JS notification mechanism events support the server to get a response from a previous API call. Single-Th
