Generate IDs with strategy like Twitter Snowflake and encode it in short string.

Properties

* 35 bit timestamp encoded to 7 characters
* 5 bit application ID encoded to 1 character
* 25 bit machine ID encoded to 5 characters
* 10 bit sequence encoded to 2 characters
* configurable timestamp precision and range
* default 1000 ms precision and more than 1000 years range from 1970 to 3000
((2^35 precision ms) / (1000 60 60 24 365)) years timestamp range

Getting Started

Install it via npm:

``shell
npm install snowflake-codon
`

Include in your project:

`javascript
var SnowflakeCodon = require("snowflake-codon");
`

Generate IDs with application ID and machine ID
`javascript
var appId = 1; // optional, default value 0
var machineId = 99; // optional, default value 0
var firstYear = 2015; // optional, default value 1970
var timestampPrecision = 200; // optional, default value 1000 (ms)
var generator = new SnowflakeCodon(appId, machineId, firstYear, timestampPrecision);
var id = generator.nextId();
// id will be something like '0fw2tte10003300'
``
