Generate two ids in an array var arr = new Array ( 32 ) // -> uuid. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)Įxample: Generate string UUID with fully-specified options The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime.Returns buffer, if specified, otherwise the string form of the UUID Offset - (Number) Starting index in buffer at which to begin writing. Default: internal uuid counter is used, as per 4.2.1.2.īuffer - (Array | Buffer) Array or buffer where UUID bytes are to be written.

nsecs - (Number between 0-9999) additional time, in 100-nanosecond units.

msecs - (Number | Date) Time in milliseconds since unix Epoch.

Default: An internally maintained clockseq is used.

clockseq - (Number between 0 - 0x3fff) RFC clock sequence.

node - (Array) Node id as Array of 6 bytes (per 4.1.6).

Options - (Object) Optional uuid state to apply. Generate and return a RFC4122 v1 (timestamp-based) UUID.
