Requiring the module returns a function to use for getting metadata about a UUID.
var uuidMeta = require('uuid-meta');
Calling the function will return an object with properties about the UUID.
var metadata = uuidMeta("ea3b9dad-6761-4939-9ac4-fa27baa38da2"); console.log(metadata.version); // 4
The interesting properties of the object returned are:
version: The version of the UUID standard used. Should be an integer between 0 and 5.
time_unix: For v1 UUIDs, the milliseconds since 1 Jan 1970 when the UUID was minted. Probably not valid for other versions.
mac_address: For v1 UUIDs, the MAC address used for minting the UUID. It's a string of 6 hexadecimal bytes separated by colons (':').
time: Time value for all UUIDs, counting 100 nanosecond periods since 15 Oct 1582. Might not be an actual time for most types of UUIDs.
node: Node identifier for minting of UUIDs. May or may not be a MAC address.
clock_seq: Clock sequence value.
There are a few other properties that come from the parsing process, but they're probably not interesting unless you're debugging the parsing process.
