npm init npm i patrun

// index.js
var patrun = require('patrun')

var pm = patrun()
      .add({a:1},'A')
      .add({b:2},'B')

// prints A
console.log( pm.find({a:1}) )

// prints null
console.log( pm.find({a:2}) )

// prints A, b:1 is ignored, it was never registered
console.log( pm.find({a:1,b:1}) )

// prints B, c:3 is ignored, it was never registered
console.log( pm.find({b:2,c:3}) )
