Understanding React Rendering Part 1 When Does React Render Ui React is a library for “rendering” ui from components, but many users find themselves confused about how react rendering actually works. what do terms like “rendering”,. React is listening to any changes to states and props. then, it will render or re render ui elements if at least one change has been made to any of the ui elements. suppose your component makes up more than one ui element.
Understanding React Rendering Part 1 When Does React Render Ui The initial render in a react app is the first render when the application starts up, while re rendering occurs when there is a change in the state to figure out which parts of the ui need an update. React’s rendering process can be broken down into three main phases. we’ll explore each one using our counter example. first, something has to tell react that it needs to update the ui . The render phase is the first part of rendering where react builds a virtual ui. this phase doesn’t have side effects like dom mutations or data fetching. it has two main steps: creating. When react renders a component, two things happen. first, react creates a snapshot of your component which captures everything react needs to update the view at that particular moment in time. props, state, event handlers, and a description of the ui (based on those props and state) are all captured in this snapshot.

When react knows how to update the dom from the render phase. it will do so in the commit phase. in this phase, react actually writes to the dom, updating, inserting and deleting elements to update the ui accordingly with the current state of our application. Rendering is the process of react asking your components to describe what they want their section of the ui to look like, now, based on the current combination of props and state. during the rendering process, react will start at the root of the component tree and loop downwards to find all components that have been flagged as needing updates. By understanding how react decides when and how to render components, developers can write more efficient and performant applications. in this article, we will break down the various rendering techniques used by react and how you can optimize your components for a smoother user experience. Rendering in react is a fundamental concept that enables the creation of dynamic and efficient user interfaces. by understanding initial rendering, re rendering, conditional rendering, list rendering, the use of keys, and the virtual dom, you can build powerful react applications.
