JSPM – mpath@0.0.1

Package Exports

mpath

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mpath) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

#mpath

{G,S}et javascript object values using MongoDB path notation.

###Getting

var mpath = require('mpath');

var obj = {
    comments: [
      { title: 'funny' },
      { title: 'exciting!' }
    ]
}

mpath.get('comments.1.title', obj) // 'exciting!'

###Setting

var obj = {
    comments: [
      { title: 'funny' },
      { title: 'exciting!' }
    ]
}

mpath.set('comments.1.title', 'hilarious', obj)
console.log(obj.comments[1].title) // hilarious

Custom object types

Sometimes you may want to enact the same functionality on custom object types that store all their real data internally, say for an ODM type object. No fear, mpath has you covered. Simply pass the name of the property being used to store the internal data and it will be traversed instead:

var mpath = require('mpath');

var obj = {
    comments: [
      { title: 'exciting!', _doc: { title: 'great!' }}
    ]
}

mpath.get('comments.0.title', obj, '_doc')            // 'great!'
mpath.set('comments.0.title', 'nov 3rd', obj, '_doc')
mpath.get('comments.0.title', obj, '_doc')            // 'nov 3rd'
mpath.get('comments.0.title', obj)                    // 'exciting'
