MongoDB Drop Collection

This lesson is part of Node.js · All levels

Summary

This lesson explains how to delete MongoDB collection entirely by drop() or db.dropCollection(name). Drop deletes the entire document, index, and definition collection in one step, so much faster than deleteMany. You also deal with errors that occur when the collection doesn't exist.

Key points

Collection.drop() or db.dropCollection(name) deleted the permanent collection.
Drop discards all indexes along with its documents (as opposed to deleteMany which maintains the index).
Running a drop on a collection that doesn't exist produces error code 26 (NSNotFound).
After the drop, a new collection is automatically re-formed when the next insert is made.
Drop is not reversible; make sure to back up or confirm before running it.
