How do I deploy a Flask application?

To deploy a Flask application, you can use platforms like Heroku, AWS, or DigitalOcean. Do you have a specific platform in mind?

I'm considering using Heroku. What are the steps?

First, make sure your app is ready for production. Then, create a Heroku account, install the Heroku CLI, and log in. Next, initialize a Git repository if you haven't already, and create a new Heroku app using heroku create. Finally, push your code using git push heroku main.

What about the database setup?

For databases, you can use Heroku Postgres. You can add it to your app with heroku addons:create heroku-postgresql:hobby-dev. Then, configure your Flask app to connect to the database using the provided URL.

Are there any common issues I should be aware of?

Yes, common issues include environment variable misconfigurations, missing dependencies, and database connection errors. Always check your logs with heroku logs --tail for troubleshooting.
