Creating the DB Schema

Lecture 276:- Creating the DB Schema

To create a schema for a MongoDB database using Mongoose, we need to define a schema using the mongoose.Schema() method. This method takes an object that defines the schema's structure.

Here is an example of creating a simple schema for a User collection with two fields name and email:

javascriptCopy code

const mongoose = require('mongoose'); const userSchema = new mongoose.Schema({  name: {    type: String,    required: true  },  email: {    type: String,    required: true,    unique: true  } }); module.exports = mongoose.model('User', userSchema);

In the above code, we first require the mongoose module and then create a userSchema using mongoose.Schema(). Inside the schema, we define two fields, name and email, both of which are required. Additionally, we make the email field unique so that there can't be any duplicate email addresses.

Finally, we export the schema as a Mongoose model using the mongoose.model() method, passing in the name of the collection as the first argument ('User') and the schema as the second argument (userSchema).

Once we have created the schema, we can use it to perform CRUD (Create, Read, Update, Delete) operations on the corresponding collection.
