# hyperid
|
||||
|
||||
[](https://github.com/mcollina/hyperid/actions)
|
||||
|
||||
Uber-fast unique id generation, for Node.js and the browser.
|
||||
Here are the benchmarks:
|
||||
|
||||
```
|
||||
crypto.randomUUID x 12,969,725 ops/sec ±0.88% (91 runs sampled)
|
||||
hashids process.hrtime x 419,350 ops/sec ±0.66% (94 runs sampled)
|
||||
hashids counter x 819,049 ops/sec ±0.58% (93 runs sampled)
|
||||
shortid x 40,820 ops/sec ±2.49% (87 runs sampled)
|
||||
crypto.random x 372,773 ops/sec ±2.39% (84 runs sampled)
|
||||
nid x 1,614,450 ops/sec ±0.38% (93 runs sampled)
|
||||
uuid.v4 x 1,446,051 ops/sec ±0.60% (98 runs sampled)
|
||||
napiRsUuid.v4 x 8,676,151 ops/sec ±0.49% (97 runs sampled)
|
||||
uuid.v1 x 2,051,072 ops/sec ±0.15% (99 runs sampled)
|
||||
nanoid x 4,293,733 ops/sec ±0.31% (97 runs sampled)
|
||||
hyperid - variable length x 25,937,129 ops/sec ±1.48% (91 runs sampled)
|
||||
hyperid - fixed length x 24,970,478 ops/sec ±1.48% (92 runs sampled)
|
||||
hyperid - fixed length, url safe x 25,856,735 ops/sec ±1.93% (92 runs sampled)
|
||||
|
||||
Fastest is hyperid - variable length,hyperid - fixed length, url safe
|
||||
Slowest is shortid
|
||||
```
|
||||
|
||||
_Note:_ Benchmark run with Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz and Node.js v22.0.0
|
||||
|
||||
As you can see the native `crypto.randomUUID` is almost as fast as hyperid
|
||||
on Node.js v16, but not on v14.
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
npm i hyperid --save
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
```js
|
||||
'use strict'
|
||||
|
||||
const hyperid = require('hyperid')
|
||||
const instance = hyperid()
|
||||
|
||||
const id = instance()
|
||||
|
||||
console.log(id)
|
||||
console.log(instance())
|
||||
console.log(hyperid.decode(id))
|
||||
console.log(hyperid.decode(instance()))
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### hyperid([fixedLength || options])
|
||||
|
||||
Returns a function to generate unique ids.
|
||||
The function can accept one of the following parameters:
|
||||
- `fixedLength: Boolean`
|
||||
If *fixedLength* is `true` the function will always generate an id
|
||||
that is 33 characters in length, by default `fixedLength` is `false`.
|
||||
- `options: Object`
|
||||
If `{ fixedLength: true }` is passed in, the function will always generate an id
|
||||
that is 33 characters in length, by default `fixedLength` is `false`.
|
||||
If `{ urlSafe: true }` is passed in, the function will generate url safe ids according to RFC4648.
|
||||
If `{ startFrom: <int> }` is passed in, the first counter will start from that
|
||||
number, which must be between 0 and 2147483647. Fractions are discarded, only the
|
||||
integer part matters.
|
||||
If `{ maxInt: <int> }` is passed in, the uuid will be re-generated once the *maxInt* is reached. The lesser the *maxInt*, higher the performance because of SMI (a V8 optimization).
|
||||
|
||||
### instance()
|
||||
|
||||
Returns an unique id.
|
||||
|
||||
### instance.uuid
|
||||
|
||||
The uuid used to generate the ids, it will change over time.
|
||||
If `maxInt` is provided in options, then it will regenerated every `maxInt`, else it will be regenerated every `Math.pow(2, 31) - 1` to keep the integer a SMI (a V8 optimization).
|
||||
|
||||
### hyperid.decode(id, [options])
|
||||
|
||||
Decode the unique id into its two components, a `uuid` and a counter.
|
||||
If you are generating *url safe* ids, you must pass `{ urlSafe: true }` as option.
|
||||
It returns:
|
||||
|
||||
```js
|
||||
{
|
||||
uuid: '049b7020-c787-41bf-a1d2-a97612c11418',
|
||||
count: 1
|
||||
}
|
||||
```
|
||||
|
||||
This is aliased as `instance.decode`.

## [8.0.0](https://github.com/uuidjs/uuid/compare/v7.0.3...v8.0.0) (2020-04-29)
|
||||
|
||||
### ⚠ BREAKING CHANGES
|
||||
|
||||
- For native ECMAScript Module (ESM) usage in Node.js only named exports are exposed, there is no more default export.
|
||||
|
||||
```diff
|
||||
-import uuid from 'uuid';
|
||||
-console.log(uuid.v4()); // -> 'cd6c3b08-0adc-4f4b-a6ef-36087a1c9869'
|
||||
+import { v4 as uuidv4 } from 'uuid';
|
||||
+uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'
|
||||
```
|
||||
|
||||
- Deep requiring specific algorithms of this library like `require('uuid/v4')`, which has been deprecated in `uuid@7`, is no longer supported.
|
||||
|
||||
Instead use the named exports that this module exports.
|
||||
|
||||
For ECMAScript Modules (ESM):
|
||||
|
||||
```diff
|
||||
-import uuidv4 from 'uuid/v4';
|
||||
+import { v4 as uuidv4 } from 'uuid';
|
||||
uuidv4();
|
||||
```
|
||||
|
||||
For CommonJS:
|
||||
|
||||
```diff
|
||||
-const uuidv4 = require('uuid/v4');
|
||||
+const { v4: uuidv4 } = require('uuid');
|
||||
uuidv4();
|
||||
```
|
||||
|
||||
### Features
|
||||
|
||||
- native Node.js ES Modules (wrapper approach) ([#423](https://github.com/uuidjs/uuid/issues/423)) ([2d9f590](https://github.com/uuidjs/uuid/commit/2d9f590ad9701d692625c07ed62f0a0f91227991)), closes [#245](https://github.com/uuidjs/uuid/issues/245) [#419](https://github.com/uuidjs/uuid/issues/419) [#342](https://github.com/uuidjs/uuid/issues/342)
|
||||
- remove deep requires ([#426](https://github.com/uuidjs/uuid/issues/426)) ([daf72b8](https://github.com/uuidjs/uuid/commit/daf72b84ceb20272a81bb5fbddb05dd95922cbba))
|
||||
|
||||
### Bug Fixes
|
||||
|
||||

## [7.0.0](https://github.com/uuidjs/uuid/compare/v3.4.0...v7.0.0) (2020-02-24)
|
||||
|
||||
### ⚠ BREAKING CHANGES
|
||||
|
||||
- The default export, which used to be the v4() method but which was already discouraged in v3.x of this library, has been removed.
|
||||
- Explicitly note that deep imports of the different uuid version functions are deprecated and no longer encouraged and that ECMAScript module named imports should be used instead. Emit a deprecation warning for people who deep-require the different algorithm variants.
|
||||
- Remove builtin support for insecure random number generators in the browser. Users who want that will have to supply their own random number generator function.
|
||||
- Remove support for generating v3 and v5 UUIDs in Node.js<4.x
|
||||
- Convert code base to ECMAScript Modules (ESM) and release CommonJS build for node and ESM build for browser bundlers.

||||
|
||||
```javascript
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'
|
||||
```
|
||||
|
||||
... or using CommonJS syntax:
|
||||
|
||||
```javascript
|
||||
const { v4: uuidv4 } = require('uuid');
|
||||
uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'

## API
|
||||
|
||||
### uuid.NIL
|
||||
|
||||
The nil UUID string (all zeros).
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { NIL as NIL_UUID } from 'uuid';
|
||||
|
||||
NIL_UUID; // ⇨ '00000000-0000-0000-0000-000000000000'
|
||||
```
|
||||
|
||||
### uuid.parse(str)
|
||||
|
||||
Convert UUID string to array of bytes
|
||||
|
||||
| | |
|
||||
| --------- | ---------------------------------------- |
|
||||
| `str` | A valid UUID `String` |
|
||||
| _returns_ | `Uint8Array[16]` |
|
||||
| _throws_ | `TypeError` if `str` is not a valid UUID |
|
||||
|
||||
Note: Ordering of values in the byte arrays used by `parse()` and `stringify()` follows the left ↠ right order of hex-pairs in UUID strings. As shown in the example below.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { parse as uuidParse } from 'uuid';
|
||||
|
||||
// Parse a UUID
|
||||
const bytes = uuidParse('6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b');
|
||||
|
||||
// Convert to hex strings to show byte order (for documentation purposes)
|
||||
[...bytes].map((v) => v.toString(16).padStart(2, '0')); // ⇨
|
||||
// [
|
||||
// '6e', 'c0', 'bd', '7f',
|
||||
// '11', 'c0', '43', 'da',
|
||||
// '97', '5e', '2a', '8a',
|
||||
// 'd9', 'eb', 'ae', '0b'
|
||||
// ]
|
||||
```
|
||||
|
||||
### uuid.stringify(arr[, offset])
|
||||
|
||||
Convert array of bytes to UUID string
|
||||
|
||||
| | |
|
||||
| -------------- | ---------------------------------------------------------------------------- |
|
||||
| `arr` | `Array`-like collection of 16 values (starting from `offset`) between 0-255. |
|
||||
| [`offset` = 0] | `Number` Starting index in the Array |
|
||||
| _returns_ | `String` |
|
||||
| _throws_ | `TypeError` if a valid UUID string cannot be generated |
|
||||
|
||||
Note: Ordering of values in the byte arrays used by `parse()` and `stringify()` follows the left ↠ right order of hex-pairs in UUID strings. As shown in the example below.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { stringify as uuidStringify } from 'uuid';
|
||||
|
||||
const uuidBytes = [
|
||||
0x6e,
|
||||
0xc0,
|
||||
0xbd,
|
||||
0x7f,
|
||||

||||
|
||||
uuidStringify(uuidBytes); // ⇨ '6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b'
|
||||
```
|
||||
|
||||
### uuid.v1([options[, buffer[, offset]]])
|
||||
|
||||

|
||||
| [`options`] | `Object` with one or more of the following properties: |
|
||||
| [`options.node` ] | RFC "node" field as an `Array[6]` of byte values (per 4.1.6) |
|
||||
| [`options.clockseq`] | RFC "clock sequence" as a `Number` between 0 - 0x3fff |

|
||||
| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
|
||||
| _throws_ | `Error` if more than 10M UUIDs/sec are requested |
|
||||
|
||||
Note: The default [node id](https://tools.ietf.org/html/rfc4122#section-4.1.6) (the last 12 digits in the UUID) is generated once, randomly, on process startup, and then remains unchanged for the duration of the process.
|
||||
|
||||
Note: `options.random` and `options.rng` are only meaningful on the very first call to `v1()`, where they may be passed to initialize the internal `node` and `clockseq` fields.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { v1 as uuidv1 } from 'uuid';
|
||||
|
||||
uuidv1(); // ⇨ '2c5ea4c0-4067-11e9-8bad-9b1deb4d3b7d'
|
||||
```
|
||||
|
||||
Example using `options`:
|
||||
|
||||
```javascript
|
||||
import { v1 as uuidv1 } from 'uuid';
|
||||
|
||||
const v1options = {
|
||||
node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
|
||||
clockseq: 0x1234,
|
||||
msecs: new Date('2011-11-01').getTime(),
|
||||
nsecs: 5678,
|
||||
};
|
||||
uuidv1(v1options); // ⇨ '710b962e-041c-11e1-9234-0123456789ab'
|
||||
```
|
||||
|
||||
### uuid.v3(name, namespace[, buffer[, offset]])
|
||||
|
||||
Create an RFC version 3 (namespace w/ MD5) UUID
|
||||
|
||||
API is identical to `v5()`, but uses "v3" instead.
|
||||
|
||||
⚠️ Note: Per the RFC, "_If backward compatibility is not an issue, SHA-1 [Version 5] is preferred_."
|
||||
|
||||
### uuid.v4([options[, buffer[, offset]]])
|
||||
|
||||
Create an RFC version 4 (random) UUID
|
||||
|
||||
| | |
|
||||
| --- | --- |
|
||||
| [`options`] | `Object` with one or more of the following properties: |
|
||||
| [`options.random`] | `Array` of 16 random bytes (0-255) |
|
||||
| [`options.rng`] | Alternative to `options.random`, a `Function` that returns an `Array` of 16 random bytes (0-255) |
|
||||
| [`buffer`] | `Array \| Buffer` If specified, uuid will be written here in byte-form, starting at `offset` |
|
||||
| [`offset` = 0] | `Number` Index to start writing UUID bytes in `buffer` |
|
||||
| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
|
||||
uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
|
||||
```
|
||||
|
||||
Example using predefined `random` values:
|
||||
|
||||
```javascript
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
|
||||
const v4options = {
|
||||
random: [
|
||||
0x10,
|
||||
0x91,
|
||||
0x56,
|
||||
0xbe,
|
||||
0xc4,
|
||||
0xfb,
|
||||
0xc1,
|
||||
0xea,
|
||||
0x71,
|
||||
0xb4,
|
||||
0xef,
|
||||
0xe1,
|
||||
0x67,
|
||||
0x1c,
|
||||
0x58,
|
||||
0x36,
|
||||
],
|
||||
};
|
||||
uuidv4(v4options); // ⇨ '109156be-c4fb-41ea-b1b4-efe1671c5836'
|
||||
```
|
||||
|
||||
### uuid.v5(name, namespace[, buffer[, offset]])
|
||||
|
||||
Create an RFC version 5 (namespace w/ SHA-1) UUID
|
||||
|
||||
| | |
|
||||
| --- | --- |
|
||||
| `name` | `String \| Array` |
|
||||
| `namespace` | `String \| Array[16]` Namespace UUID |
|
||||
| [`buffer`] | `Array \| Buffer` If specified, uuid will be written here in byte-form, starting at `offset` |
|
||||
| [`offset` = 0] | `Number` Index to start writing UUID bytes in `buffer` |
|
||||
| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
|
||||
|
||||
Note: The RFC `DNS` and `URL` namespaces are available as `v5.DNS` and `v5.URL`.
|
||||
|
||||
Example with custom namespace:
|
||||
|
||||
```javascript
|
||||
import { v5 as uuidv5 } from 'uuid';
|
||||
|
||||
// Define a custom namespace. Readers, create your own using something like
|
||||
// https://www.uuidgenerator.net/
|
||||
const MY_NAMESPACE = '1b671a64-40d5-491e-99b0-da01ff1f3341';
|
||||
|
||||
uuidv5('Hello, World!', MY_NAMESPACE); // ⇨ '630eb68f-e0fa-5ecc-887a-7c7a62614681'
|
||||
```
|
||||
|
||||
Example with RFC `URL` namespace:
|
||||
|
||||
```javascript
|
||||
import { v5 as uuidv5 } from 'uuid';
|
||||
|
||||
uuidv5('https://www.w3.org/', uuidv5.URL); // ⇨ 'c106a26a-21bb-5538-8bf2-57095d1976c1'
|
||||
```
|
||||
|
||||
### uuid.validate(str)
|
||||
|
||||
Test a string to see if it is a valid UUID
|
||||
|
||||
| | |
|
||||
| --------- | --------------------------------------------------- |
|
||||
| `str` | `String` to validate |
|
||||
| _returns_ | `true` if string is a valid UUID, `false` otherwise |
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { validate as uuidValidate } from 'uuid';
|
||||
|
||||
uuidValidate('not a UUID'); // ⇨ false
|
||||
uuidValidate('6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b'); // ⇨ true
|
||||
```
|
||||
|
||||
Using `validate` and `version` together it is possible to do per-version validation, e.g. validate for only v4 UUIds.
|
||||
|
||||
```javascript
|
||||
import { version as uuidVersion } from 'uuid';
|
||||
import { validate as uuidValidate } from 'uuid';
|
||||
|
||||
function uuidValidateV4(uuid) {
|
||||
return uuidValidate(uuid) && uuidVersion(uuid) === 4;
|
||||
}
|
||||
|
||||
const v1Uuid = 'd9428888-122b-11e1-b85c-61cd3cbb3210';
|
||||
const v4Uuid = '109156be-c4fb-41ea-b1b4-efe1671c5836';
|
||||
|
||||
uuidValidateV4(v4Uuid); // ⇨ true
|
||||
uuidValidateV4(v1Uuid); // ⇨ false
|
||||
```
|
||||
|
||||
### uuid.version(str)
|
||||
|
||||
Detect RFC version of a UUID
|
||||
|
||||
| | |
|
||||
| --------- | ---------------------------------------- |
|
||||
| `str` | A valid UUID `String` |
|
||||
| _returns_ | `Number` The RFC version of the UUID |
|
||||
| _throws_ | `TypeError` if `str` is not a valid UUID |
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { version as uuidVersion } from 'uuid';
|
||||
|
||||
uuidVersion('45637ec4-c85f-11ea-87d0-0242ac130003'); // ⇨ 1
|
||||
uuidVersion('6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b'); // ⇨ 4
|
||||
```
|
||||
|
||||
## Command Line
|
||||
|
||||
UUIDs can be generated from the command line using `uuid`.
|
||||
|
||||
```shell
|
||||
$ uuid
|
||||
ddeb27fb-d9a0-4624-be4d-4615062daed4
|
||||
```
|
||||
|
||||
The default is to generate version 4 UUIDS, however the other versions are supported. Type `uuid --help` for details:
|
||||
|
||||
```shell
|
||||
$ uuid --help
|
||||
|
||||
Usage:
|
||||
uuid
|
||||
uuid v1
|
||||
uuid v3 <name> <namespace uuid>
|
||||
uuid v4
|
||||
uuid v5 <name> <namespace uuid>
|
||||
uuid --help
|
||||
|
||||
Note: <namespace uuid> may be "URL" or "DNS" to use the corresponding UUIDs
|
||||
defined by RFC4122
|
||||
```
|
||||
|
||||
## ECMAScript Modules
|
||||
|
||||
This library comes with [ECMAScript Modules](https://www.ecma-international.org/ecma-262/6.0/#sec-modules) (ESM) support for Node.js versions that support it ([example](./examples/node-esmodules/)) as well as bundlers like [rollup.js](https://rollupjs.org/guide/en/#tree-shaking) ([example](./examples/browser-rollup/)) and [webpack](https://webpack.js.org/guides/tree-shaking/) ([example](./examples/browser-webpack/)) (targeting both, Node.js and browser environments).
|
||||
|
||||
```javascript
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
|
||||
```
|
||||
|
||||
To run the examples you must first create a dist build of this library in the module root:
|
||||
|
||||
```shell
|
||||
npm run build
|
||||
```
|
||||
|
||||
## CDN Builds
|
||||
|
||||
### ECMAScript Modules
|
||||
|
||||
To load this module directly into modern browsers that [support loading ECMAScript Modules](https://caniuse.com/#feat=es6-module) you can make use of [jspm](https://jspm.org/):
|
||||
|
||||
```html
|
||||
<script type="module">
|
||||
import { v4 as uuidv4 } from 'https://jspm.dev/uuid';
|
||||
console.log(uuidv4()); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
|
||||
</script>
|
||||
```
|
||||
|
||||
### UMD
|
||||
|
||||
To load this module directly into older browsers you can use the [UMD (Universal Module Definition)](https://github.com/umdjs/umd) builds from any of the following CDNs:
|
||||
|
||||
**Using [UNPKG](https://unpkg.com/uuid@latest/dist/umd/)**:
|
||||
|
||||
```html
|
||||
<script src="https://unpkg.com/uuid@latest/dist/umd/uuidv4.min.js"></script>
|
||||
```
|
||||
|
||||
**Using [jsDelivr](https://cdn.jsdelivr.net/npm/uuid@latest/dist/umd/)**:
|
||||
|
||||
```html
|
||||
<script src="https://cdn.jsdelivr.net/npm/uuid@latest/dist/umd/uuidv4.min.js"></script>
|
||||
```
|
||||
|
||||
**Using [cdnjs](https://cdnjs.com/libraries/uuid)**:
|
||||
|
||||
```html
|
||||
<script src="https://cdnjs.cloudflare.com/ajax/libs/uuid/8.1.0/uuidv4.min.js"></script>
|
||||
```
|
||||
|
||||
These CDNs all provide the same [`uuidv4()`](#uuidv4options-buffer-offset) method:
|
||||
|
||||
```html
|
||||
<script>
|
||||
uuidv4(); // ⇨ '55af1e37-0734-46d8-b070-a1e42e4fc392'
|
||||
</script>
|
||||
```
|
||||
|
||||
Methods for the other algorithms ([`uuidv1()`](#uuidv1options-buffer-offset), [`uuidv3()`](#uuidv3name-namespace-buffer-offset) and [`uuidv5()`](#uuidv5name-namespace-buffer-offset)) are available from the files `uuidv1.min.js`, `uuidv3.min.js` and `uuidv5.min.js` respectively.
|
||||
|
||||
## "getRandomValues() not supported"
|
||||
|
||||
This error occurs in environments where the standard [`crypto.getRandomValues()`](https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues) API is not supported. This issue can be resolved by adding an appropriate polyfill:
|
||||
|
||||
### React Native / Expo
|
||||
|
||||
1. Install [`react-native-get-random-values`](https://github.com/LinusU/react-native-get-random-values#readme)
|
||||
1. Import it _before_ `uuid`. Since `uuid` might also appear as a transitive dependency of some other imports it's safest to just import `react-native-get-random-values` as the very first thing in your entry point:
|
||||
|
||||
```javascript
|
||||
import 'react-native-get-random-values';
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
```
|
||||
|
||||
Note: If you are using Expo, you must be using at least `react-native-get-random-values@1.5.0` and `expo@39.0.0`.
|
||||
|
||||
### Web Workers / Service Workers (Edge <= 18)
|
||||
|
||||
[In Edge <= 18, Web Crypto is not supported in Web Workers or Service Workers](https://caniuse.com/#feat=cryptography) and we are not aware of a polyfill (let us know if you find one, please).
|
||||
|
||||
## Upgrading From `uuid@7.x`
|
||||
|
||||
### Only Named Exports Supported When Using with Node.js ESM
|
||||
|
||||
`uuid@7.x` did not come with native ECMAScript Module (ESM) support for Node.js. Importing it in Node.js ESM consequently imported the CommonJS source with a default export. This library now comes with true Node.js ESM support and only provides named exports.
|
||||
|
||||
Instead of doing:
|
||||
|
||||
```javascript
|
||||
import uuid from 'uuid';
|
||||
uuid.v4();
|
||||
```
|
||||
|
||||
you will now have to use the named exports:
|
||||
|
||||
```javascript
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
uuidv4();
|
||||
```
|
||||
|
||||
### Deep Requires No Longer Supported
|
||||
|
||||
Deep requires like `require('uuid/v4')` [which have been deprecated in `uuid@7.x`](#deep-requires-now-deprecated) are no longer supported.
|
||||
|
||||
## Upgrading From `uuid@3.x`
|
||||
|
||||
"_Wait... what happened to `uuid@4.x` - `uuid@6.x`?!?_"
|
||||
|
||||
In order to avoid confusion with RFC [version 4](#uuidv4options-buffer-offset) and [version 5](#uuidv5name-namespace-buffer-offset) UUIDs, and a possible [version 6](http://gh.peabody.io/uuidv6/), releases 4 thru 6 of this module have been skipped.
|
||||
|
||||
### Deep Requires Now Deprecated
|
||||
|
||||
`uuid@3.x` encouraged the use of deep requires to minimize the bundle size of browser builds:
|
||||
|
||||
```javascript
|
||||
const uuidv4 = require('uuid/v4'); // <== NOW DEPRECATED!
|
||||
uuidv4();
|
||||
```
|
||||
|
||||
As of `uuid@7.x` this library now provides ECMAScript modules builds, which allow packagers like Webpack and Rollup to do "tree-shaking" to remove dead code. Instead, use the `import` syntax:
|
||||
|
||||
```javascript
|
||||
import { v4 as uuidv4 } from 'uuid';
|
||||
uuidv4();
|
||||
```
|
||||
|
||||
... or for CommonJS:
|
||||
|
||||
```javascript
|
||||
const { v4: uuidv4 } = require('uuid');
|
||||
uuidv4();
|
||||
```
|
||||
|
||||
### Default Export Removed
|
||||
|
||||
`uuid@3.x` was exporting the Version 4 UUID method as a default export:
|
||||
|
||||
```javascript
|
||||
const uuid = require('uuid'); // <== REMOVED!
|
||||
```
|
||||
|
||||
This usage pattern was already discouraged in `uuid@3.x` and has been removed in `uuid@7.x`.
