Fetching last record from mongodb using node.js

Question

I am trying to fetch last record from mongodb database using node.js. I found some answer from here . Now i have given query like

Videopost.find({}).sort({_id:-1}).limit(10,function(err,docs){}

Trying to print docs in console but couldn't get any value in docs.

Answer 1

limit不带回调参数，因此您必须调用exec才能实际执行查询。

Videopost.find({}).sort({_id:-1}).limit(10).exec(function(err,docs) {...});

Answer 2

In case somebody is looking for the answer for node.js , you can use findOne() function. This worked for me:

db.collection('collectionName').findOne(
  {},
  { sort: { _id: -1 } },
  (err, data) => {
     console.log(data);
  },
);
