Learn to build and deploy a web application in Piglet Run.

Create a FastAPI App

1. Set Up Project 

cd ~/workspace
mkdir myapp && cd myapp
python -m venv venv
source venv/bin/activate
pip install fastapi uvicorn psycopg[binary]

2. Create Application

Create main.py:

from fastapi import FastAPI
import psycopg

app = FastAPI()

@app.get("/")
def root():
    return {"message": "Hello from Piglet Run!"}

@app.get("/users")
def get_users():
    conn = psycopg.connect("postgres://postgres@localhost/postgres")
    cur = conn.execute("SELECT * FROM users")
    return cur.fetchall()

if __name__ == "__main__":
    import uvicorn
    uvicorn.run(app, host="0.0.0.0", port=8000)

3. Run Locally
