CRUD operations in Node.js using MongoDB and mongoose
⭕ Overview
Hello everyone, this is Christian again. In this video, we're going to continue from our previous session where we connected to a MongoDB database using the native MongoDB driver. This time, we're going to enhance our application by using Mongoose, an Object Data Modeling (ODM) library for MongoDB and Node.js. Mongoose provides a more robust and feature-rich way to interact with MongoDB, allowing us to define schemas, models, and perform validations easily.
To begin, let's briefly recap what we did last time. We performed CRUD (Create, Read, Update, Delete) operations using the native MongoDB driver. This involved functions like `insertOne`, `insertMany`, `update`, and `delete`. Now, we'll achieve similar functionality but with Mongoose, which simplifies these operations and adds more capabilities.
First, I'll show you how to set up Mongoose in our Node.js application. We'll start by installing Mongoose and updating our application to use it. This involves replacing the native MongoDB connection code with Mongoose's connection setup. We'll also define a schema for our data, which allows us to enforce data structure and validation rules.
Next, we'll rewrite our CRUD operations using Mongoose methods. For instance, instead of using `insertOne` and `insertMany`, we'll use Mongoose's `save` method on our models. Similarly, for updates and deletions, Mongoose provides intuitive methods that align closely with our previous approach but with added benefits like middleware and hooks.
I'll guide you through making a copy of our previous setup, keeping most of the structure intact while modifying the parts necessary to integrate Mongoose. We'll go through the process step-by-step, ensuring you understand how to leverage Mongoose's power to enhance your Node.js applications.
By the end of this tutorial, you'll have a solid understanding of how to use Mongoose with MongoDB in your Node.js projects. This will make your code cleaner, more maintainable, and scalable, taking advantage of Mongoose's advanced features.
