Server-side rendering with React

  • What is server-side rendering (SSR)?
  • Why SSR
  • Working with render To String and render To Static Markup methods

Feature of ReactJS

  • Virtual DOM- Like an actual DOM, virtual DOM is also a node tree that lists the elements and their attributes and content as Objects and their properties. React’s render function creates a node tree out of the react components. Then, it updates this tree in data model caused by various actions done either by the user or by the system.
  • JSX- JSX stands for JavaScript XML and is a React extension that allows us to write JavaScript that looks like HTML. JSX makes React a lot more elegant and it is an object-oriented programming language designed to run on modern web browsers.
  • Server-Side Rendering (SSR) - Server-Side rendering allows you to pre-render the initial state of your react components at the server side only. The server’s response to the browser becomes only the HTML of the page which is now ready to be rendered with SSR. Thus, the browser can now start rendering without having to wait for all the JavaScript to be loaded and executed.
  • One-way Data Binding- Unlike other frameworks, ReactJS follows unidirectional data flow or one-way data binding. The main benefit of One-Way-Data binding is that throughout the application the data flows in a single direction which gives you better control over it.
  • Learning Curve- With a basic knowledge of programming you can learn ReactJS. If you have previous knowledge of HTML, you can easily learn ReactJS.

Benefits of ReactJS

  • Single Page Application
  • Entire page remains the same but only a few components change
  • A Code is easy to scale and maintain
  • More functionalities as HTML is created from JS
  • Isomorphic Rendering (Server-side rendering)
  • Easy to learn and use
  • Simplicity
