UUID v4 in React-Javascript

UUID stands for Universally Unique Identifier which is a string of 32 characters that is used to identify something in a uniquely defined way. These strings are generated random and can be used in instances where unique identifiers are required such as for generating IDs, session IDs, transaction IDs, or for creating unique keys in react-apps.

Generating UUID v4 in React-Javascript

In order to generate UUID v4 in React-Javascript, we can make use of the uuid library which can be installed using npm. The package can be installed using the following command:

npm install uuid

Once installed, we can import the v4 function from the package in our React component and use it to generate UUID v4 as shown in the following code snippet:

import { v4 as uuidv4 } from 'uuid';

function App() {
  const uuid = uuidv4();
  return (
    <div>
      <h1>UUID v4 Generated: {uuid}</h1>
    </div>
  );
}

In the above code, we imported the v4 function from the uuid package and aliased it as uuidv4. We then used the uuidv4 function to generate the UUID v4 and stored it in the uuid constant. Finally, we displayed the generated UUID in our react component.

Summary

In conclusion, we can generate UUID v4 in React-Javascript using the uuid library which is a simple and efficient way to generate UUIDs. We can use these UUIDs to generate unique identifiers for different purposes in our React applications.
