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:
npm install snowflake-codon
Include in your project:
var SnowflakeCodon = require("snowflake-codon");
Generate IDs with application ID and machine ID
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'
