Create forms using Uncontrolled Components in ReactJS |ReactJS Essentials|
In this video, I'll explain how to create and use uncontrolled components in React, which are components where form elements, like text inputs, checkboxes, and select dropdowns, manage their own state internally. Unlike controlled components, uncontrolled components do not rely on React’s state to manage the value of the input fields. Instead, the DOM itself handles the state of the form elements. For example, I'll show you how to create an uncontrolled form input that tracks the user’s input directly in the DOM, rather than React state. This is done by using React’s useRef hook to create a reference to the input field, which allows us to interact with the DOM directly and access the current value of the input without needing to bind it to React’s state. An uncontrolled component works by letting the form elements maintain their own internal state. When a user interacts with the input field, the value is updated in the DOM, and we can access that value using the ref—no need for React to re-render the component every time the input changes. If you're looking to simplify your code or work with a form where you don’t need full control over each field, this video will demonstrate how to build an uncontrolled component for a text input and explain why uncontrolled components can sometimes be a simpler, more performant solution. You’ll learn how to wire up refs to form elements, how to access their values directly, and when it might make sense to use uncontrolled components in your React apps.
