How do I design a schema for a MongoDB database using Node.js?

To design a schema in MongoDB with Node.js, you can use Mongoose, which provides a straightforward way to define schemas.

What are the key components of a Mongoose schema?

A Mongoose schema typically includes fields, data types, validation rules, and methods. You define these in a JavaScript object.

Can you give me an example of a simple user schema?

Sure! Here's a basic example:

const userSchema = new mongoose.Schema({ name: { type: String, required: true }, email: { type: String, required: true, unique: true }, password: { type: String, required: true }, createdAt: { type: Date, default: Date.now } });

How do I validate the email field in the schema?

You can use a regex pattern for email validation in Mongoose like this:

email: { type: String, required: true, match: /.+@.+..+/ }.
