Finding most recent entry in a meteor collection

Question

My task sounds simple, but I can\'t nail down how to write this... I simply want to find the most recent item inserted into a collection and display it on my meteor app.

Answer 1

I could only get the desired result by doing

let commentsTmp: Comment = Comments.findOne({ parentId: this.currentPost._id }, { sort: { time: -1 } });

with MongoObservable.Collection<T>

Hope this will help someone.

Answer 2

As per the docs you can also do:

return Collection.findOne({}, {sort: {DateTime: -1, limit: 1}});

Provided that DateTime is this field that you do Date.parse(Date()). Also you don't have to store dates as unix timestamps you can just do new Date() and it would be stored as the Date object type.
