TurboGears can be used as a microframework in single-file mode. To create a minimal application, define a class inheriting from TGController, use the @expose decorator to make methods accessible via URLs, and use MinimalApplicationConfigurator to configure the application and map your root controller.
from wsgiref.simple_server import make_server
from tg import MinimalApplicationConfigurator
from tg import expose, TGController
# RootController of our web app, in charge of serving content for /
class RootController(TGController):
@expose(content_type="text/plain")
def index(self):
return 'Hello World'
# Configure a new minimal application with our root controller.
config = MinimalApplicationConfigurator()
config.update_blueprint({
'root_controller': RootController()
})
# Serve the newly configured web application.
print("Serving on port 8080...")
httpd = make_server('', 8080, config.make_wsgi_app())
httpd.serve_forever()
