rack

var hat = require('hat');
var rack = hat.rack();

console.log(rack());
console.log(rack());

output:

methods

var hat = require('hat');

hat(bits=128, base=16)

Generate a random ID string with bits of data in a base.

Leading zeros are appended such that all outputs for a given number of bits have equal length.

var rack = hat.rack(bits=128, base=16, expandBy)

Make a new hat rack. Call rack() repeatedly to generate new IDs which are checked for collisions.

If expandBy is specified, increment bits by this amount if too many collisions occur. If expandBy isn't specified, rack() will throw if too many collisions occur during generation.

Optionally call var id = rack(data) to store data at the new ID.

You can get the data out again with rack.get(id) and set the data with rack.set(id, value).

how to make a hat

First you will need a large square of cloth or paper. These materials work well:

  • large napkin
  • newspaper

If you find yourself at a fancy restaurant, large napkins are in abundant supply.

Tie a knot in each corner. Place the hat on your head and enjoy!
