This plugin is a highly customised version of mongoose-shortid, without bignum.

You can get it via npm by typing:

npm install mongoose-minid

This plugin provides a new Schema Type, ShortId, that can be used in place of ObjectId. The generated IDs are random url-safe strings of configurable length, represented in a 64 bit string.

This plugin will automatically retry inserts on a collision, up to a maximum of 5 retries.

This module is going to make your ObjectId from something like 507f191e810c19729de860ea to just Ng3zf_

var mongoose = require('mongoose');
var ShortId = require('mongoose-minid');
var personSchema = mongoose.Schema({
 _id: ShortId,
 name: String
});

The default options are:

var personSchema = mongoose.Schema({
 _id: {
 type: ShortId,
 len: 7 // Length 7 characters
 },
 name: String
});
