[SOLVED] How to apply a Mongo modifier to a local object?

[trusktr]

Suppose we have

var o = {a:1}
var modifier = {$set: {a:2}}

Is there some Meteor API to apply the modifier directly to o?

I found mupdate on npm, which does the job to some degree: it doesn’t have all the possible operators.

Mongo update operators on regular objects

this might sound strange but I’d like to use mongo style operations on regular objects. Specifically, the update operators like $set, $push, etc. Something like sourceObject = {foo: {bar: false}} mUpdate(sourceObject, {$set {{'foo.bar': 'baz'}}) // sourceObject is now {foo: {bar: 'baz'}} Is there an easy way to accomplish this?

Mongo update operators on regular objects

minimongo can probably handle this; haven’t tried it though. meteor add minimongo then try: var sourceObject = {foo: {bar: false}} var operator = {$set: {'foo.bar': 'baz'}} LocalCollection._modify(sourceObject, operator); console.log(sourceObject) // {foo: {bar: 'baz'}}

Yep, that’s the one LocalCollection._modify

@nathan_muir That was what I needed. Thanks!
