# uuid [](http://travis-ci.org/kelektiv/node-uuid) #
|
|
|
|
Simple, fast generation of [RFC4122](http://www.ietf.org/rfc/rfc4122.txt) UUIDS.
|
|
|
|
Features:
|
|
|
|
* Support for version 1, 3, 4 and 5 UUIDs
|
|
* Cross-platform
|
|
* Uses cryptographically-strong random number APIs (when available)
|
|
* Zero-dependency, small footprint (... but not [this small](https://gist.github.com/982883))
|
|
|
|
[**Deprecation warning**: The use of `require('uuid')` is deprecated and will not be
|
|
supported after version 3.x of this module. Instead, use `require('uuid/[v1|v3|v4|v5]')` as shown in the examples below.]
|
|
|
|
## Quickstart - CommonJS (Recommended)
|
|
|
|
```shell
|
|
npm install uuid
|
|
```
|
|
|
|
Then generate your uuid version of choice ...
|
|
|
|
Version 1 (timestamp):
|
|
|
|
```javascript
|
|
const uuidv1 = require('uuid/v1');
|
|
uuidv1(); // ⇨ '45745c60-7b1a-11e8-9c9c-2d42b21b1a3e'
|
|
|
|
```
|
|
|
|
Version 3 (namespace):
|
|
|
|
```javascript
|
|
const uuidv3 = require('uuid/v3');
|
|
|
|
// ... using predefined DNS namespace (for domain names)
|
|
uuidv3('hello.example.com', uuidv3.DNS); // ⇨ '9125a8dc-52ee-365b-a5aa-81b0b3681cf6'
|
|
|
|
// ... using predefined URL namespace (for, well, URLs)
|
|
uuidv3('http://example.com/hello', uuidv3.URL); // ⇨ 'c6235813-3ba4-3801-ae84-e0a6ebb7d138'
|
|
|
|
// ... using a custom namespace
|
|
//
|
|
// Note: Custom namespaces should be a UUID string specific to your application!
|
|
// E.g. the one here was generated using this modules `uuid` CLI.
|
|
const MY_NAMESPACE = '1b671a64-40d5-491e-99b0-da01ff1f3341';
|
|
uuidv3('Hello, World!', MY_NAMESPACE); // ⇨ 'e8b5a51d-11c8-3310-a6ab-367563f20686'
|
|
|
|
```
|
|
|
|
Version 4 (random):
|
|
|
|
```javascript
|
|
const uuidv4 = require('uuid/v4');
|
|
uuidv4(); // ⇨ '10ba038e-48da-487b-96e8-8d3b99b6d18a'
|
|
|
|
```
|
|
|
|
Version 5 (namespace):
|
|
|
|
```javascript
|
|
const uuidv5 = require('uuid/v5');
|
|
|
|
// ... using predefined DNS namespace (for domain names)
|
|
uuidv5('hello.example.com', uuidv5.DNS); // ⇨ 'fdda765f-fc57-5604-a269-52a7df8164ec'
|
|
|
|
// ... using predefined URL namespace (for, well, URLs)
|
|
uuidv5('http://example.com/hello', uuidv5.URL); // ⇨ '3bbcee75-cecc-5b56-8031-b6641c1ed1f1'
|
|
|
|
// ... using a custom namespace
|
|
//
|
|
// Note: Custom namespaces should be a UUID string specific to your application!
|
|
// E.g. the one here was generated using this modules `uuid` CLI.
|
|
const MY_NAMESPACE = '1b671a64-40d5-491e-99b0-da01ff1f3341';
|
|
uuidv5('Hello, World!', MY_NAMESPACE); // ⇨ '630eb68f-e0fa-5ecc-887a-7c7a62614681'
|
|
|
|
```

## API
|
|
|
|
### Version 1
|
|
|
|
```javascript
|
|
const uuidv1 = require('uuid/v1');
|
|
|
|
// Incantations
|
|
uuidv1();
|
|
uuidv1(options);
|
|
uuidv1(options, buffer, offset);
|
|
```
|
|
|
|
Generate and return a RFC4122 v1 (timestamp-based) UUID.
|
|
|
|
* `options` - (Object) Optional uuid state to apply. Properties may include:
|
|
|
|
* `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID. See note 1.
|
|
* `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence. Default: An internally maintained clockseq is used.
|
|
* `msecs` - (Number) Time in milliseconds since unix Epoch. Default: The current time is used.
|
|
* `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.
|
|
|
|
* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
|
|
* `offset` - (Number) Starting index in `buffer` at which to begin writing.
|
|
|
|
Returns `buffer`, if specified, otherwise the string form of the UUID
|
|
|
|
Note: The <node> id is generated guaranteed to stay constant for the lifetime of the current JS runtime. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)
|
|
|
|
Example: Generate string UUID with fully-specified options
|
|
|
|
```javascript
|
|
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'
|
|
|
|
```
|
|
|
|
Example: In-place generation of two binary IDs
|
|
|
|
```javascript
|
|
// Generate two ids in an array
|
|
const arr = new Array();
|
|
uuidv1(null, arr, 0); // ⇨ [ 69, 117, 109, 208, 123, 26, 17, 232, 146, 52, 45, 66, 178, 27, 26, 62 ]
|
|
uuidv1(null, arr, 16); // ⇨ [ 69, 117, 109, 208, 123, 26, 17, 232, 146, 52, 45, 66, 178, 27, 26, 62, 69, 117, 109, 209, 123, 26, 17, 232, 146, 52, 45, 66, 178, 27, 26, 62 ]
|
|
|
|
```

|
|
|
### Version 3

|
|
uuidv3(name, namespace, buffer);
|
|
uuidv3(name, namespace, buffer, offset);
|
|
```
|
|
|
|
Generate and return a RFC4122 v3 UUID.
|
|
|
|
* `name` - (String | Array[]) "name" to create UUID with
|
|
* `namespace` - (String | Array[]) "namespace" UUID either as a String or Array[16] of byte values
|

|
|
|
```javascript
|

|
|
```
|
|
|
|
### Version 4

* `offset` - (Number) Starting index in `buffer` at which to begin writing.
|
|
|

|
|
|

Example: Generate string UUID with predefined `random` values
|
|
|
|
