It will always create unique id's based on the current time, process and machine name.
npm install uniqid
var uniqid = require('uniqid');
console.log(uniqid()); // -> 4n5pxq24kpiob12og9 console.log(uniqid(), uniqid()); // -> 4n5pxq24kriob12ogd, 4n5pxq24ksiob12ogl
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" ```
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.
uniqid.process() -> "24ieiob0te82"
Generate 8 byte unique id's based on the current time only. Recommended only on a single process on a single machine.
uniqid.time() -> "iob0ucoj"
Since browsers don't provide a Process ID and in most cases neither give a Mac Address using uniqid from Webpack and Browserify falls back to
uniqid.time()for all the other methods too. The browser is the single process, single machine case anyway.
Debug messages are turned off by default as of
v4.1.0. To turn on debug messages you'll need to set
truebefore you require the module.
// enable debug messages module.uniqid_debug = true;
// require the module var uniqid = require('uniqid');
