Choose the application

Each example application store in a sub-folder:

Then click the "Execute" button, it will send a request to the related endpoint and retrieve the response back:

$ flask run --reload

Or run in debug mode:

$ flask run --debug

With debug mode, it will enable the reloader and debugger as default. See Debug Mode for more details.
