MongoDB Insert

This lesson is part of Node.js · All levels

Summary

This lesson teaches how to add documents to MongoDB collection from Node.js using insertOne and insertMany. Every document that is saved automatically has a unique IDs that you can use as a reference. You also see the return of the result (insertedId, insertedCount) to ensure the operation is successful.

Key points

InsertOne inserts a document and returns it.
InsertMany inserts many documents; use {ordered: false} so that one failure does not stop the rest.
Field_id is automated if you don't fill it yourself.
You can keep documents with different structures in one collection.
Validation (e.g. duplication of unique index) remains valid and will throw error to await.
