Second, such an approach can lead to invalid HTML, as you’re going to see.įor example, let’s say you have a Table component which renders an HTML table, whose columns are rendered with another component called Columns. First, by using this approach consistently, you’re making your DOM more nested, and consequently slower to be rendered. By using the empty tag syntax one doesn’t have to either import React or write the long keyword React.Fragment every time. From a logical point of view, this extra can usually be considered irrelevant, but it does have consequences. Create fragment instance, and objects will be added to container. The easiest solution would be to use a wrapper. A button with a label and react on click event Create styles from scratch for buttons. However, some key differences make them suitable. The first argument ( child) is any renderable React child, such as an element, string, or fragment. ![]() This is because React requires that components return only one HTML element. In React, the React Fragment and the div element serve as containers for grouping multiple elements together. These new documentation pages teach modern React and include live examples: Portals provide a first-class way to render children into a DOM node that exists outside the DOM hierarchy of the parent component. Issue: In React, when you create a component that returns multiple HTML tags, you'll often need to wrap them in a single parent element like a
.
To achieve this, you must wrap all these elements with an HTML tag. React fragments can help you wrap multiple components within an HTML tag without disrupting the DOM nodes in your codebase. Why React Fragments ExistĪs stated in the official React documentation, returning more than one HTML element is a commonly desired behavior for React components. So, let’s see everything you need to master React Fragments, by diving into the Why, the What, the How, and the When.
