id-shorter/test.js

A little module that replaces a long ObjectId value with short one keeping uniqueness. A charset for conversion is fully configurable and does not depend on requirement of 64 symbols. So it is possible to use only letters, letters+digits, digits etc.

var ObjectId = require('bson').ObjectId;

var ShortId = require('./index.js');
var mongoDBShortId = ShortId();

// console.log('Default configuration: very short mongoDB object Id');
// for (var i = 0; i < 2; i++)
// {
// 	var testObjectId = new ObjectId();
// 	var result = mongoDBShortId.encode(testObjectId);
// 	console.log(testObjectId + ' = ' + result);
// }
//
// var shortId = ShortId({
// 	isFullId: true
// });
// console.log('\nUse full ObjectId value with reverse possibility');
//
// for (var i = 0; i < 2; i++)
// {
// 	var testObjectId = new ObjectId();
// 	var result = shortId.encode(testObjectId);
// 	console.log(testObjectId + ' = ' + result);
// }
//
// console.log('\nTest reversible decoding');
// var decodeResult = shortId.decode(result);
// console.log(result + ' = ' + decodeResult);
//
// var result = 'xk4pZ11XpLsWPy1Cl';
// var decodeResult = shortId.decode(result);
// console.log(result + ' = ' + decodeResult + '(566062cfa72f67b07e644521)');
//
// console.log('\nTest absolutely custom config');
//
// var Bin2Hex = ShortId({
// 	base: '01',
// 	encoding: '0123456789abcdef',
// 	isInverse: false,
// 	//isFullId: true,
