Javascript validator for UUID versions 1 through 5

uuid-validator

Useful little package to validate UUIDs in Node.js. Usage:

var validate = require('uuid-validate');

// Let's validate a uuid version 1. If we don't pass a version, it'll
// infer it based on the uuid itself.
validate('95ecc380-afe9-11e4-9b6c-751b66dd541e'); // => true

// We can tell it what version to expect, and if it gets the wrong
// version, it'll return false.
validate('95ecc380-afe9-11e4-9b6c-751b66dd541e', 1); // => true (it's version 1)
validate('95ecc380-afe9-11e4-9b6c-751b66dd541e', 4); // => false (it's not version 4)

// You can also pass buffers instead of strings.
// This works for UUID versions 1 through 4

// If you want to find out what version a UUID is:
validate.version('95ecc380-afe9-11e4-9b6c-751b66dd541e'); // => 1

uuid-validate's Issues

version() returns false positives for strings that are too large

Maybe this is not how the library is intended to be used. If that is the case, then please close.

Steps to reproduce

var uuidValidate = require("uuid-validate")

// Behaves as expected
uuidValidate('b38d63b5-524f-468c-b1c8-942c8c2284325') // => false

uuidValidate.version('b38d63b5-524f-468c-b1c8-942c8c2284325') // => 4

Expected behavior

Would it make sense to have version() also return false if the UUID is invalid?

false negatives

Testing these two uuid's returns false:

• c9cfe3e0-e298-7a36-9c88-7c2acf143bab
• c9cfe3e0-e298-7a36-9c88-7c2acf144eec

Whereas

!/^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$/.test('c9cfe3e0-e298-7a36-9c88-7c2acf143bab')

is true.

Above test from here: https://stackoverflow.com/a/13653180/712005

does v4 validation really work?

> var validate = require('uuid-validate');
> var uuid = require('node-uuid');
> var u = uuid.v4()
> validate(u)
false
> u
'97a90793-4898-4abe-b255-e8dc6967ed40'
> validate(u,4)
false
> validate(u,1)
true
> validate.version(u)
4

As you can see, it validates as version 1, but validate.version() returns version 4. Something isn't right.

Valid uuid marked as invalid

I've found an instance of a valid v3 uuid that gets identified as non valid, 4810935e-168b-3d7d-7a42-081999ff18bb. I've checked multiple tools and all seem to agree that this is indeed a valid uuid
