What are some examples of using Mongoose in Node.js?

Can you give me some examples of how to use Mongoose in a Node.js application?

Sure! Mongoose is an ODM (Object Data Modeling) library for MongoDB and Node.js. Here are a few examples.

What is the basic setup for Mongoose?

To set up Mongoose, first install it using npm: npm install mongoose. Then, connect to your MongoDB database like this:

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });

How do I define a schema in Mongoose?

You can define a schema using the Schema class. For example:

const userSchema = new mongoose.Schema({
  name: String,
  age: Number,
  email: String
});

Can you show me how to create a model from the schema?

Absolutely! You can create a model like this:

const User = mongoose.model('User', userSchema);
