 
### A Unique Hexatridecimal ID generator.
It will always create unique id's based on the current time, process and machine name.
```js
// install with npm
npm install uniqid
// install with yarn
yarn add uniqid
```
## Usage
```js
import uniqid from 'uniqid';
console.log(uniqid()); // -> 4n5pxq24kpiob12og9
console.log(uniqid(), uniqid()); // -> 4n5pxq24kriob12ogd, 4n5pxq24ksiob12ogl
```
## Usage with Require
```js
var uniqid = require('uniqid');
console.log(uniqid()); // -> 4n5pxq24kpiob12og9
console.log(uniqid(), uniqid()); // -> 4n5pxq24kriob12ogd, 4n5pxq24ksiob12ogl
```
## Usage in Browser

```html
<!DOCTYPE html>
<html lang="en">
<head>
<script src="https://unpkg.com/browse/uniqid@5.5.0/UMD/uniqid.min.js"></script>
<script>
alert(`Here is an ID: ${uniqid()}`)
</script>

```
## Features
- Very fast
- Generates unique id's on multiple processes and machines even if called at the same time.
- Shorter 8 and 12 byte versions with less uniqueness.
# How it works
- With the current time the ID's are always unique in a single process.
- With the Process ID the ID's are unique even if called at the same time from multiple processes.
- With the MAC Address the ID's are unique even if called at the same time from multiple machines and processes.
## API:
#### **uniqid(** prefix _optional string_ , suffix _optional string_ **)**
Generate 18 byte unique id's based on the time, process id and mac address. Works on multiple processes and machines.
```js "zu4850jkyfoxok"
uniqid() -> "4n5pxq24kpiob12og9"
uniqid('hello-') -> "hello-4n5pxq24kpiob12og9"
uniqid('hello-', '-goodbye') -> "hello-4n5pxq24kpiob12og9-goodbye"
// usage with suffix only
uniqid('', '-goodbye') -> "4n5pxq24kpiob12og9-goodbye"
uniqid(undefined, '-goodbye') -> "4n5pxq24kpiob12og9-goodbye"
```
#### **uniqid.process(** prefix _optional string_ , suffix _optional string_ **)**
Generate 12 byte unique id's based on the time and the process id. Works on multiple processes within a single machine but not on multiple machines.
```js
uniqid.process() -> "24ieiob0te82"
```
#### **uniqid.time(** prefix _optional string_ , suffix _optional string_ **)**
Generate 8 byte unique id's based on the current time only. Recommended only on a single process on a single machine.
```js
uniqid.time() -> "iob0ucoj"
```
## Webpack, Browserify, Vite
Since browsers don't provide a Process ID and in most cases neither give a Mac Address using uniqid from Webpack, Browserify and Vite falls back to `uniqid.time()` for all the other methods too. The browser is the single process, single machine case anyway.
## Debug
Debug messages are turned off by default as of `v4.1.0`. To turn on debug messages you'll need to set `uniqid_debug` to `true` before you require the module.
```js
// enable debug messages
module.uniqid_debug = true;
// require the module
var uniqid = require('uniqid');
```
