I want to create a document which automatically gets deleted on specific time using mongoose in NodeJS.
Writing this as a new question since I can find only TTL based solutions, I need expiry time based.

MongoDB supports auto deleting documents. https://docs.mongodb.com/manual/tutorial/expire-data/
In order to use this in Mongoose you need to create an index on the collection using this syntax:
MySchema.index( { "expireAt": 1 }, { expireAfterSeconds: 0 } );
You also need to create a field in schema named expireAt and add the time at which you want the document to expire while adding document in the collection.

After creating the above index just add a field named as expireAt in the record that you want to delete and set value of expireAt as the time at which you want to delete the record. Ex { name: a, expireAt: <time of deletion of a> }, { name: b, expireAt: <time of deletion of b> }
