useId hooks
useId
is a React Hook for generating unique IDs that can be passed to accessibility attributes. This hook helps components to become a unique identifier. By generating and managing unique IDs dynamically, components can enhance accessibility by ensuring proper labeling and identification, particularly for interactive elements.
Syntax:
const id = useId()
Parameters:
useId
does not take any parameters.
Returns:
useId
returns a unique ID string associated with this particular useId
call in this particular component.
Usage
- Generating unique IDs for accessibility attributes
- Generating IDs for several related elements
- Specifying a shared prefix for all generated IDs
- Using the same ID prefix on the client and the server
Example: In this example we are providing same id’s to both password and confirm password to display the same content.
Javascript
import { useId } from 'react' ; function PasswordField() { const passwordHintId = useId(); return ( <> <label> Password: <input type= "password" aria-describedby={passwordHintId} /> </label> <p id={passwordHintId}> The password should contain at least 18 characters </p> </> ); } export default function App() { return ( <> <h2>Choose password</h2> <PasswordField /> <h2>Confirm password</h2> <PasswordField /> </> ); } |

Other Hooks in React
React provides specialized built-in hooks for building reusable components and libraries. While they are used less, these hooks are important in providing library authors to create robust and user-friendly applications. Among these specialized hooks are useDebugValue
and useId
, that provides unique functionalities that enhance the developer experience and facilitate the creation of reusable and accessible components. In this article, we’ll look into these hooks.
