Readme
Yeast is a unique id generator. It has been primarily designed to generate a unique id which can be used for cache busting. A common practice for this is to use a timestamp, but there are couple of downsides when using timestamps.
Yeast solves both of these issues by:
encode()
function that
returns a string representation of the number.To keep the strings unique it will use the .
char to separate the generated
stamp from the seed.
The module is intended to be used in browsers as well as in Node.js and is therefore released in the npm registry and can be installed using:
npm install --save yeast
All the examples assume that this library is initialized as follow:
'use strict';
var yeast = require('yeast');
To generate an id just call the yeast
function.
console.log(yeast(), yeast(), yeast()); // outputs: KyxidwN KyxidwN.0 KyxidwN.1
setTimeout(function () {
console.log(yeast()); // outputs: KyxidwO
});
An helper function that returns a string representing the specified number. The returned string contains only URL safe characters.
yeast.encode(+new Date()); // outputs: Kyxjuo1
An helper function that returns the integer value specified by the given string.
This function can be used to retrieve the timestamp from a yeast
id.
var id = yeast(); // holds the value: Kyxl1OU
yeast.decode(id); // outputs: 1439816226334
That's all folks. If you have ideas on how we can further compress the ids please open an issue!
