从MongoDB集合中的数组更新对象

Question

I need to send an array of objects with respective ID's from client-side code via JSON to an API endpoint that is serve by ExpressJS.

Now I need to update existing DB objects with all the fields from the array of objects. I suppose a for..in loop doesn't look good in this case. Neither did I find a way to update multiple documents in one run.

I use MongoJS library to work with MongoDB from NodeJS

Please advise.

db.mycollection.update({name:'some name'}, {$inc:{level:1}}, {multi:true}, function() { // the update is complete });
