If you are looking for only one object to be removed  you can use   Person findOne   id  req params id   function  error  person           console log  This object will get deleted     person           person remove               In this example  Mongoose will delete based on matching req params id

Simply do  FBFriendModel remove   exec

Be careful with findOne and remove     User findOne  name   Alice    remove   exec      The code above removes ALL users named  Alice  instead of the first one only   By the way  I prefer to remove documents like this     User remove        exec      Or provide a callback and omit the exec      User remove        callback

remove   has been deprecated  Use deleteOne    deleteMany   or bulkWrite     The code I use  TeleBot deleteMany  chatID  chatID   function  err                       if  err                        return console log err

If you don t feel like iterating  try FBFriendModel find   id 333    remove  callback    or FBFriendModel find   id 333    remove   exec     mongoose model find returns a Query  which has a remove function   Update for Mongoose v5 5 3 - remove   is now deprecated  Use deleteOne    deleteMany   or findOneAndDelete   instead

For removing document  I prefer using Model remove conditions   callback    Please refer API documentation for remove  -  http   mongoosejs com docs api html model Model remove  For this case  code will be -  FBFriendModel remove   id   333    function err  callback   console log    Do Stuff           If you want to remove documents without waiting for a response from MongoDB  do not pass a callback  then you need to  call exec on the returned Query   var removeQuery   FBFriendModel remove  id   333     removeQuery exec

Update   remove   is depreciated but this still works for older versions  YourSchema remove       foo  req params foo    function err           if  err  return res send err      res json           message   deleted    req params foo

This for me is the best as of version 3 8 1   MyModel findOneAndRemove  field   newValue    function err           And it requires only one DB call   Use this given that you don t perform any remove actions pior to the search and removal

This worked for me  just try this   const id   req params id        YourSchema        remove   id  id          exec          then result   gt            res status 200  json             message   deleted             request                type   POST               url   http   localhost 3000 yourroutes                                          catch err   gt            res status 500  json             error  err

mongoose model find   returns a Query Object which also has a remove   function   You can use mongoose model findOne   as well  if you want to remove only one unique document   Else you can follow traditional approach as well where you first retrieving the document and then remove   yourModelObj findById id  function  err  doc        if  err               handle error            doc remove callback     Removes the document      Following are the ways on model object you can do any of the following to remove document s    yourModelObj findOneAndRemove conditions  options  callback    yourModelObj findByIdAndRemove id  options  callback   yourModelObj remove conditions  callback    var query   Comment remove    id  id     query exec

To generalize you can use   SomeModel find   where  function err docs     if  err  return console log err     if   docs     Array isArray docs     docs length     0       return console log  no docs found      docs forEach  function  doc        doc remove                Another way to achieve this is   SomeModel collection remove  function  err      if  err  throw err       collection is now empty but not deleted

You can always use Mongoose built-in function   var id   req params friendId    here you pass the id     FBFriendModel     findByIdAndRemove id      exec       then function doc           return doc         catch function error           throw error

I really like this pattern in async await capable Express Mongoose apps   app delete    idToDelete   asyncHandler async  req  res    gt      const deletedItem   await YourModel      findByIdAndDelete req params idToDelete     This method is the nice method for deleting      catch err   gt  res status 400  send err message      res status 200  send deletedItem

UPDATE  Mongoose version  5 5 3   remove   is deprecated and you can use deleteOne    deleteMany    or bulkWrite   instead   As of  mongoose     gt  2 7 1  you can remove the document directly with the  remove   method rather than finding the document and then removing it which seems to me more efficient and easy to maintain   See example   Model remove    id  req body id    function err        if   err                message type    notification              else               message type    error               UPDATE   As of mongoose 3 8 1  there are several methods that lets you remove directly a document  say    remove findByIdAndRemove findOneAndRemove   Refer to mongoose API docs for further information

docs is an array of documents  so it doesn t have a mongooseModel remove   method   You can iterate and remove each document in the array separately   Or - since it looks like you are finding the documents by a  probably  unique id - use findOne instead of find
