Generate random IDs and avoid collisions.
var hat = ;var id = ;console;
var hat = ;var rack = hat;console;console;
var hat = require('hat');
Generate a random ID string with
bits of data in a
Leading zeros are appended such that all outputs for a given number of bits have equal length.
Make a new hat rack. Call
rack() repeatedly to generate new IDs which are
checked for collisions.
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.
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
