Build a Stock Screener using FastAPI (Python)

Didn't see a lot of examples out there for this framework, so decided to create one.

Step 1: Hello World of FastAPI, Stub out the API endpoints

• Display Hello World
• Map out endpoints we will need, comment what they will do

Step 2: Mock the UI with Semantic UI and Jinja2 Templates

• Including CSS and JavaScript from the CDN

Step 3: Database Design

• To design our database, we create SQLAlchemy models
• See what yfinance provides
• forwardPE, forwardEps, dividendYield, 50 Day, 200 Day, Close
• SQLAlchemy create_all

Step 4: Add a stock endpoint

• Background task to fetch info and add to db also
• Use Insomnia to test it

Step 5: Wire home screen

• Show added stocks in a table

Step 6: Filters to filter table

• Filter boxes on UI
• Use SQLALchemy to filter in db
• Use query parameters to filter

Step 7: Modal to add stock tickers via UI
