MongoMatcher

Run mongo selector on an arbitrary javascript object to see if it is matched!

###USAGE###

First, import MongoMatcher using the require command. MongoMatcher has a dependency on LoDash

var mongoMatcher = require('./mongoMatcher.js');

Now, you can instantiate a matcher for a given MongoDB selector object, like so:

var mySelector = {$and:[{foo:"bar"},{wham:"bam"}]}
var myMatcher = new mongoMatcher(mySelector);

After you do this, you can see if a Javascript object would be matched by the MongoDB selector using the discern function

var willMatch = {foo:"bar",wham:"bam"}
var wontMatch = {foo:"baz",wham:"bam"}

myMatcher.discern(willMatch)	//true
myMatcher.discern(wontMatch)	//false

And that's it!

###LIMITATIONS###

Currently, MongoMatcher is meant only for MongoDB selectors (not modifiers) and does not support all keywords. Hopefully all the keywords will be supported in the future: feel free to contribute them!

Unsupported operators are:

• $type
• $regex
• $where
• $text
• $geoIntersects
• $geoWithin
• $nearSphere
• $near
• $
• $elemMatch
• $meta
• $slice
