Performing Basic Operations with Mongoose
Once you have defined your models, you can perform basic CRUD (Create, Read, Update, Delete) operations using Mongoose methods:
Create: To create a new document in the database, you can use the create() method:
//Pseudo code for create
const newUser = await User.create({ username: 'gfg', email: 'gfg@example.com', age: 30 });
Read: To retrieve documents from the database, you can use methods like find() or findOne():
//Pseudo code for Read
const users = await User.find({ age: { $gte: 25 } });
Update: To update existing documents, you can use methods like updateOne() or findByIdAndUpdate():
//Pseudo code for update
await User.updateOne({ username: 'gfg' }, { age: 35 });
Delete: To delete documents from the database, you can use methods like deleteOne() or findByIdAndDelete():
//Pseudo code for deletion
await User.deleteOne({ username: 'gfg' });
Understanding Mongoose Middleware in Node.js
A Mongoose is a powerful tool for NodeJS developers working with MongoDB databases. It simplifies database interaction, allowing developers to focus more on building their applications. In this article, we’ll cover the basics of Mongoose, including how to connect to a MongoDB database and perform CRUD operations. We’ll also explore Mongoose middleware, which lets developers add custom code before or after database operations, and share some best practices for using Mongoose efficiently.
