FastAPI CRUD Example

This is a simple FastAPI application that demonstrates basic CRUD operations for blog posts using in-memory storage (a Python list). It does not use any views or templates — purely an API backend.

🚀 Features

• 🟢 Get all posts
• 🟡 Create a new post
• 🔵 Get a single post by ID
• 🔴 Delete a post by ID

🔧 Requirements

• Python 3.7+
• FastAPI
• Uvicorn

Install dependencies:

pip install fastapi uvicorn

▶️ Running the Application

Use uvicorn to run the FastAPI app:

uvicorn main:app --reload

• --reload: enables hot-reload on code changes (useful for development)

🌐 API Endpoints

Method	Endpoint	Description
GET	/	Root message
GET	/posts	Retrieve all posts
POST	/posts	Create a new post
GET	/posts/{id}	Retrieve a post by ID
DELETE	/posts/{id}	Delete a post by ID

Example POST Body

{
  "title": "Sample Title",
  "content": "Sample content goes here",
  "published": true,
  "rating": 5
}

📦 Notes

• The application uses in-memory storage (my_posts list), so data resets every time the server restarts.
• ID is randomly generated using Python's randrange.
