Productionise the code
In production, Flask’s built-in server (app.run()) should typically not be used. Instead, you should use a production-ready server like Gunicorn or uWSGI. Here’s how you can change it:
pip install gunicorn
Add wsgi.py file at root level
from app import create_app
app = create_app() # Create the Flask application instanceHow to simulate production environment locally
Option 1:
- Set FLASK_ENV=production in .env file
When deploying your Flask application with Gunicorn, you should reference the app object exposed in your wsgi.py file.
- Run the app
gunicorn --bind 0.0.0.0:8080 wsgi:app⇒ visit http://127.0.0.1:8080
Explanation:
• wsgi:app: This tells Gunicorn to look for the app variable inside the wsgi.py module.
• —bind 0.0.0.0:8080: Binds the server to all interfaces on port 8080.
flask run
Or
gunicorn wsgi:app
or
gunicorn -c gunicorn.conf.py wsgi:app
