Tix

Tix is a unique id generator.

  1. Gives you unique ids
  2. Keeps track of whether a given id has been taken
  3. You can release a previously taken id
  4. Automatically expands backing store
  5. Uses bitmasks on an integer array for speed and awesomeness
var Tix = require('tix');
 
var ids = new Tix();
 
var id = ids.take(); // 0
 
var anotherId = ids.take(); // 1
 
ids.has(1); // true
ids.has(2); // false
 
var id = ids.take(); // 2
ids.has(2); // false
 
ids.release(1);
ids.has(1); // false
 
var id = ids.take() // 1
