A Mongoose schema is a blueprint for your data in MongoDB. It defines the structure of documents within a collection.

Can you show me an example of a simple Mongoose schema?

Sure! Here's a basic example:

const mongoose = require('mongoose');

const userSchema = new mongoose.Schema({
  name: { type: String, required: true },
  email: { type: String, required: true, unique: true },
  age: { type: Number, min: 0 }
});

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

What are the different data types I can use in a Mongoose schema?

Mongoose supports various data types like String, Number, Date, Buffer, Boolean, Mixed, ObjectId, and Array.

How do I add validation to my Mongoose schema?
