Use npm uuid in reactjs

As of September,2020 I got this working by first, installing the types as

yarn add @types/uuid

then as

import React from "react";
import ReactDOM from "react-dom";
import { v4 as uuidv4 } from 'uuid';

function App() {
  return (
    <div className="App">
      <h1>{uuidv4()}</h1>
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

If this code don't work in future, refer to this section of official docs.

Try this:

import React from "react";
import ReactDOM from "react-dom";
import uuid from "uuid";

function App() {
  return (
    <div className="App">
      <h1>{uuid.v4()}</h1>
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

This is a working example: https://codesandbox.io/s/0pr5vz48kv

You don't have to require the package always. Just require it only once and use it wherever you want.

const uuidv1 = require('uuid/v1');

if (condition) {
    some_id = uuidv1();
    some_function(some_id);

} else {
    other_id = uuidv1();
    other_function(other_id);
}

It's as simple as that.
