run flask application in development mode stack overflow

To run a Flask application in development mode, you can follow the steps below:

1. Import the Flask module: Begin by importing the Flask module in your Python script. This module contains the necessary functionality to create a Flask application.

2. Create a Flask application instance: Next, create an instance of the Flask application using the Flask class. This instance will be used to define the routes and handle the incoming requests.

3. Define routes: Use the @app.route() decorator to define the routes for your application. Routes are the URLs that users can access to interact with your application. You can specify the URL pattern and the HTTP methods that should be allowed for each route.

4. Define route functions: For each route, you need to define a function that will handle the requests made to that route. These functions will contain the logic to process the requests and generate the appropriate responses.

5. Run the application: Finally, to run the Flask application in development mode, you can use the app.run() method. By default, this method starts the application on a local development server, which can be accessed in your web browser.

During development, you may want to set some additional configurations. For example, you can enable debug mode by setting the debug parameter of the app.run() method to True. This will provide detailed error messages and automatically reload the application whenever you make changes to the code.

It's worth noting that running a Flask application in production mode requires a different setup, such as using a production-ready server like Gunicorn or uWSGI.
