Project Title: Recipe Sharing Platform - Backend

Description

This repository contains the backend code for the Recipe Sharing Platform, built using Django. The backend provides API endpoints for managing recipes and integrates with a React frontend deployed on AWS S3 and CloudFront.

Features

• RESTful API for recipe management
• User authentication and authorization
• CRUD operations for recipes
• Image handling for recipe images
• PostgreSQL database integration
• Additional endpoints for updating and deleting recipes by name and user ID

Technologies Used

• Django
• Django Rest Framework
• PostgreSQL
• AWS EC2
• AWS S3
• AWS CloudFront

Installation and Setup

1. Clone the repository:

   git clone https://github.com/yourusername/recipe-sharing-backend.git
   cd recipe-sharing-backend

2. Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

4. Setup the PostgreSQL database and update settings.py:

   DATABASES = {
       'default': {
           'ENGINE': 'django.db.backends.postgresql',
           'NAME': 'your_db_name',
           'USER': 'your_db_user',
           'PASSWORD': 'your_db_password',
           'HOST': 'your_db_host',
           'PORT': 'your_db_port',
       }
   }
   
   ALLOWED_HOSTS = ['your_ec2_public_ipv4']

5. Run migrations and start the development server:

   python manage.py migrate
   python manage.py runserver

Deployment on AWS

Deploying Django Backend on EC2

1. Launch an EC2 instance and SSH into it.

2. Install required software:

   sudo apt update
   sudo apt install python3-pip python3-dev libpq-dev nginx curl
   sudo apt install postgresql postgresql-contrib

3. Clone the repository and set up the virtual environment:

   git clone https://github.com/yourusername/recipe-sharing-backend.git
   cd recipe-sharing-backend
   python3 -m venv venv
   source venv/bin/activate
   pip install -r requirements.txt

4. Configure PostgreSQL and update settings.py as mentioned above.

5. Run migrations:

   python manage.py migrate

6. Configure Gunicorn:

   pip install gunicorn
   gunicorn --workers 3 --bind unix:/home/ubuntu/recipe-sharing-backend/recipe-sharing-backend.sock wsgi:application

7. Configure Nginx:

   sudo nano /etc/nginx/sites-available/recipe-sharing

   Add the following configuration:

   server {
       listen 80;
       server_name your_server_ip;
   
       location / {
           include proxy_params;
           proxy_pass http://unix:/home/ubuntu/recipe-sharing-backend/recipe-sharing-backend.sock;
       }
   }

   Enable the configuration:

   sudo ln -s /etc/nginx/sites-available/recipe-sharing /etc/nginx/sites-enabled
   sudo nginx -t
   sudo systemctl restart nginx
   sudo systemctl restart gunicorn

Deploying React Frontend on S3 and CloudFront

1. Build the React project:

   npm run build

2. Upload the build folder to an S3 bucket:

   aws s3 sync build/ s3://your-s3-bucket-name

3. Set up CloudFront to serve the S3 bucket content.

Accessing the API

Use the EC2 instance's public IPv4 address as the backend URL to call the endpoints. For example:

• GET: http://<ec2_public_ipv4>/api/recipes/
• POST: http://<ec2_public_ipv4>/api/recipes/
• GET: http://<ec2_public_ipv4>/api/recipes/user/{uid}
• PUT: http://<ec2_public_ipv4>/api/recipes/update/<name>/<uid>/
• DELETE: http://<ec2_public_ipv4>/api/recipes/delete/<name>/<uid>/
