If you re using Mongoose  the only way to be sure to have the id as an hex String seems to be    object  id   object  id toHexString   object toHexString      This is because object  id exists only if the object is populated  if not the object is an ObjectId

When using mongoose    A representation of the  id is usually in the form  recieved client side      id          bsontype   ObjectID          id   lt Buffer 5a f1 8f 4b c7 17 0e 76 9a c0 97 aa gt       As you can see there s a buffer in there  The easiest way to convert it is just doing  lt obj gt  toString   or String  lt obj gt   id   So for example  var mongoose   require  mongoose   mongoose connect  http   localhost test   var personSchema   new mongoose Schema   name  String    var Person   mongoose model  Person   personSchema  var guy   new Person   name   someguy     Person find   then  people    gt     people forEach person   gt        console log typeof person  id    outputs object     typeof person  id     string          null         sale  id   String sale  id      all  id s will be converted to strings         catch err  gt   console log  errored

The result returned by find is an array    Try this instead   console log user 0    id

take the underscore out and try again   console log user id    Also  the value returned from id is already a string  as you can see here   I m using it this way and it works   Cheers

Try this   user  id toString     A MongoDB ObjectId is a 12-byte UUID can be used as a HEX string representation with 24 chars in length  You need to convert it to string to show it in console using console log   So  you have to do this   console log user  id toString

User · Answer

There are two ways to do this    in stead of using user  id use user id and it will return a string for you If you really want to go the long way around you can use user  id toString
