What is a Mongoose schema and how do I create one?

A Mongoose schema is a blueprint for defining the structure of documents within a MongoDB collection. You can create one using the new Schema() method.

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

Sure! Here's a basic example:

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

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

What are the benefits of using Mongoose schemas?

Mongoose schemas provide structure, validation, and type casting for your data, making it easier to work with MongoDB.

How do I validate data in a Mongoose schema?

You can add validation rules directly in the schema definition, like required, min, max, or custom validators.
