Random-ID produces Base64-URI Encoded ids with 128 bits of random information.
These are roughly equivalent to UUIDs, but they do not have the correct formatting or special bits set. If you're just looking for a quick way to generate a long random id that is uri-safe, then this library might be just what you needed =)
This is not RFC4122 complaint! Use https://github.com/broofa/node-uuid if you want RFC-Compliant UUIDs
USAGE: newId(length, radix)
length - the desired number of characters radix - the number of allowable values for each character, 64 by default.
npm install uuid-pure var newId = require("uuid-pure").newId;
// No arguments - returns a 22 character long base64-uri random string >>> newId() 'DPBCJL-P3trJvvqvvH2yOj' // One argument - returns ID of the specified length >>> newId(15) // 15 character ID (default base=62) '2oXmp_mD7WWA04T' // Two arguments - returns ID of the specified length, and radix. (Radix must be <= 64) >>> newId(8, 2) // 8 character ID (base=2) "01001010" >>> newId(8, 10) // 8 character ID (base=10) "47473046" >>> newId(8, 16) // 8 character ID (base=16) "098F4D35"
It is common to want to generate a new id that has a prefix. To make that easier, uuid-pure comes with a currying function.
>>> var uuid = require("uuid-pure"); >>> var itemId = uuid.withPrefix("/item/"); >>> itemId(); '/item/jkWk0RYLXqF6UUoF-RYvsb'

This library was previously called uuid-pure-js, and it is the npm package uuid-pure and not random-id for historical reasons.
Robert Kieffer pointed out that this is not an RFC-compliant uuid and requested that I remove the attribution as the work is materially different than his original Math.uuid.js library. If you're looking to work with systems that require an RFC-compliant UUID, please use his excellent node-uuid library which works on both the server and the browser. For a faster (but requiring native code) solution, see https://bitbucket.org/nikhilm/uuidjs.
