How to get data from mongodb collection in the form?

You get an invalid json:

 [ key : { value1 : '123', value2 : '123' } ] 

I suppose you need to get all the same array:

 [ { "key" : { "value1" : "123", "value2" : "123" } } ] 

Then you can use the map :

 db.test.insert({value1: '123', value2: '123'}) db.test.find().map(function(e) {return {key: e};}
