Release Highlight

MongoDB Standardized Logging 📝

The driver's standardized logger is now available! The primary goal of our driver's logger is to enable insight into database operations without code changes so the enablement and configuration of the logger are primarily done through or environment variables.

TL;DR Show me the logs!

env MONGODB_LOG_ALL=debug node server.mjs

A complete list of the environment variables, and details on how to set them can be found in the MongoDB manual here: https://www.mongodb.com/docs/drivers/node/current/fundamentals/logging

Tip

If you are a CLI app developer (or otherwise take great care of your std outputs): The client options constructor argument takes precedence over environment variables, permitting you to disable or otherwise customize the logger so your app does not automatically respond to the current environment.
