64-bits unique ID generator for Node.js written in C++.
This is an experimental module. We strongly discourage you to use it production for the moment since we don't have tested it enough.
Despite, if you want to use and contribute to this module, your help is welcome!
This module requires OS X 10.7 (or later) and Xcode 4.5 (or later) to be built.
Linux support is plan to be added in a near future.
npm install flocon --save
var flocon = require('flocon'); var id = flocon.snow();
Returns a Snowflake-inspired 64-bit IDs String object constructed using:
|Time (milliseconds)||41 bits||Time elapsed since epoch, hardcoded to January 1st, 2013.|
|Process ID||10 bits||
Process ID that is generating the 64-bits ID.
Can handle up to 1024 different process ID.
Incremental value starting from 0 and re initialised every ms.
Can generate 8192 per process per ms.
.snow()can generate a total of
