Data Modeling for Backend with mongoose

Mongoose

Mongoose is a powerful tool used for data modeling in backend development. It provides a structured way to organize your application data using schemas, making it easier to manage and interact with databases.

• Data modeling is the process of structuring project content in an organized way.

• Mongoose offers built-in features for type conversion, validation, creating queries, adding business logic, and more.

• Before starting to build the backend, it's crucial to structure the backend layout effectively.

  To illustrate, consider a website that includes a registration page, login page, YouTube content, and a chatbot. Creating a diagram for this structure can be beneficial. Page

Standard Way to Structure Data Model

The main folder is models, which contains subfolders and model files for different components of the application:

• Subfolder: e-commerce

• Model files:

  • user.models.js

  • category.models.js

  • product.models.js

  • order.models.js

Data Modeling

Here's a basic example of how to define a user model using Mongoose:

1. Import Mongoose: import mongoose from 'mongoose'

2. Define the schema: const userSchema = new mongoose.Schema({},{})

3. Export the model: export const User = mongoose.model('User', userSchema)

For a practical example, you can refer to this Data Modeling Project.

import mongoose from 'mongoose'

const userSchema = new mongoose.Schema(
{
    username: {
        type: String,
        required: true
    },
    password: {
        type: String,
    }
},{timestamps: true})

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