Accepted answer

Because the uuid package has not default export, as the error clearly states.

(it used to exist, but has been removed)

Once installed, decide which type of UUID you need. RFC4122 provides for four versions, all of which are supported here.

(documentation at https://www.npmjs.com/package/uuid)

so you need to choose one of the following

import {v1 as uuid} from "uuid"; 
// import {v3 as uuid} from "uuid"; 
// import {v4 as uuid} from "uuid"; 
// import {v5 as uuid} from "uuid"; 

depending on the implementation you want.


If you are using an older version of the package you could use one of

import uuid from 'uuid/v1'
// import uuid from 'uuid/v3'
// import uuid from 'uuid/v4'
// import uuid from 'uuid/v5'

  1. yarn add uuid
  2. import {v4 as uuid} from 'uuid'
  3. console.log(uuid());

Create Version 4 (Random) UUIDs

import { v4 as uuidv4 } from 'uuid';

id:uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d' https://www.npmjs.com/package/uuid

It worked for me after removed the node_modules and package-lock.json and reinstalled the npm install and npm install react-scripts.

As others have already stated, destructure the variable:

const { v4 as uuid } from 'uuid';

For use in your code:

const id = uuid();

If you are coming across this error in your Jest tests add the following to your moduleNameMapper:

moduleNameMapper: {
    '^uuid$': 'uuid'
}

In the command line, run

npm i react-uuid

then in your project, try

import uuid from 'react-uuid';
const id = uuid();

score:0

write

const uuid = require('uuid');

instead of

import uuid from 'uuid'

score:0

import uuid from 'uuid/dist/v4'
this will work

Sometimes and often times (due to some incomplete/interrupted dependency installations) all you need to do is delete the node_modules folder and run npm install once more.
Voila (in most cases).

I think if you add to uuid when you import it v4 I think it will work

What I mean is like this

import uuid from 'uuid/v4';

score:1

Instead of doing: import uuid from 'uuid'

This worked for me(For creating random string): import uuid from 'uuid/v4'

score:1

I used this:

import v1 from 'uuid/v1.js' 

const uuid = v1;

and it worked!!

Default exports have been removed as stated on the npm page of UUID.

From nmpjs.com

Default Export Removed

uuid@3 was exporting the Version 4 UUID method as a default export:

const uuid = require('uuid'); // <== REMOVED!

This usage pattern was already discouraged in uuid@3 and has been removed in uuid@7.

in the command line install uuid:

npm i react-uuid

in your project:

import { v4 as uuid } from "uuid";

const id = uuid();

score:3

Use react-uuid

npm i react-uuid
import uuid from 'react-uuid';

const id = uuid();

score:3

Earlier it was possible to access the default state, which is not available in new release.
Kindly go through the updates: https://www.npmjs.com/package/uuid.

import { v4 as uuidv4 } from 'uuid';

There are other possible access ways provided in package in npm documentation.

This worked for me.

Firstly, run

npm install uuid

then

import { v4 as uuidv4 } from 'uuid';

To use it just call uuidv4().

Once you do yarn add uuid, the uuid folder in node_modules contains v1,v2,v3,v4 modules. import any of them according to your choice as uuid.

import {v4 as uuid} from 'uuid'
const id = uuid()

This solved my problem. versions "uuid": "^7.0.3" and "react": "^16.13.1",
