Cat Adoption Application

Welcome to the Cat Adoption Application! This full-stack application is built with NestJS for the backend and Vite React for the frontend.

Installation ✨

To get started with the development environment, follow these steps:

1. Clone this repository to your local machine:

git clone https://github.com/iamsrikanthnani/cat-adoption.git

2. Install dependencies for both the backend and frontend:

npm install

3. Set up environment variables for backend, do cd backend and then:

• Copy the .env.example file and rename it to .env.

cp .env.example .env

• Open the .env file in a text editor and fill in the following variables:

POSTGRES_HOST=localhost
POSTGRES_PORT=5432
POSTGRES_USER=[Your PostgreSQL Username]
POSTGRES_PASSWORD=[Your PostgreSQL Password]
POSTGRES_DB=[Your PostgreSQL Database Name]
JWT_SECRET_KEY=[Your JWT Secret Key]

Make sure to replace the values with appropriate ones based on your PostgreSQL configuration and desired JWT secret key.

4. Set up environment variables for frontend, do cd frontend and then:

• Copy the .env.example file and rename it to .env.

cp .env.example .env

• Open the .env file in a text editor and fill in the following variables:

VITE_API_URL=http://localhost:3000/[ADD BACKEND API URL]

Make sure to add the backend API URL to the frontend .env.

5. Start the development servers for both the backend and frontend:

npm run start

This will start both the backend server (NestJS) and frontend server (Vite React) concurrently.

Entity Relations ✨

In this project, I have established several entity relations to organize and manage data effectively. Below are the details of the entity relations:

👤 User to 🐱 Cat Relation

• Description: Enables each user to have multiple cats associated with them.
• Purpose: Facilitates better organization and management of cat data per user.
• Implementation: This relation is established through a one-to-many association, where each user can have multiple cats.

👤 User to ⭐ Favorite Relation

• Description: Enables each user to have multiple favorites associated with them.
• Purpose: Allows users to save and manage their favorite cats effectively.
• Implementation: This relation is established through a one-to-many association, where each user can have multiple favorites.

These entity relations play a crucial role in structuring the data and enhancing the functionality of the application.
