Mastering MEAN Web Development Expert Full Stack JavaScript (Video 15)

This video tutorial covers the use of Mongoose for interacting with a MongoDB database. It explains how to create a schema for a Jedi Master model, implement a master controller, and test the API using Postman. The tutorial highlights the benefits of Mongoose, such as simplifying data querying and updating, and introduces lifecycle hooks and static methods. It concludes with a brief mention of using Mocha for integration testing.
