elo-mongoose

elo mongoose plugin

A mongoose plugin that adds the ability to use the elo rating system on a model. Built using my elo-rank library. Note: only tested on node v5.0.0

example

const mongoose = require('mongoose');
const eloPlugin = require('elo-mongoose');
 
let schema = new mongoose.Schema({
    name: String
});
 
schema.plugin(eloPlugin);
 
const TestModel = mongoose.model('TestModel', schema);
 
TestModel.create({
    name: 'test',
    rating: 1500
}, (err, model) => {
    console.log(model.rating) // => 1500
 
    // First id is the winner
    TestModel.updateRatings(model.id, someOtherId, (err, models) {
        //returns both models with their update ratings
        console.log(models);
    });
});

api
