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
