How can I integrate validation with MongoDB?

You can use Mongoose, a popular ODM for MongoDB, to define schemas with validation rules.

What kind of validation can I implement using Mongoose?

Mongoose allows you to implement required fields, data types, custom validation, and more.

Can you show me an example of a schema with validation?

Sure! Here's a simple example:

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

This schema requires a name and email, and ensures age is a non-negative number.

What happens if the validation fails?

If validation fails, Mongoose will throw a validation error, and you can handle it in your application.
