How do I create a Mongoose schema for my MongoDB database?

To create a Mongoose schema, you first need to define the structure of your data. You can do this by using the Schema class from Mongoose.

Can you show me a simple example of a 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 }
});

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

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

Mongoose supports various data types like String, Number, Date, Buffer, Boolean, Mixed, ObjectId, and Array. You can also create custom types.

How do I validate data in my schema?

You can add validation rules directly in your schema definition. For example, you can set required: true for mandatory fields or use custom validation functions.
