App¶

The App object encapsulates the application's event loop. An example app would look like this:

import appier

class HelloApp(appier.App):

    @appier.route("/", "GET")
    def hello(self):
        return "Hello World"

To start the app do the following:

HelloApp().serve()

The App can be configured by defining its init method:

class HelloApp(appier.App):

    def __init__(self, *args, **kwargs):
        appier.App.__init__(
            self,
            name = "app_name",
            *args, **kwargs
        )

The basic App should seldom be inherited from, instead opt for inheriting from APIApp or WebApp, depending on whether you're building just an API or a complete Web App with an user interface. These will provide default behaviours that are more appropriate to each scenario. For example, by inheriting from WebApp instead, the following behaviours are done by default:

• Provide a default handler for the index route, so that the developer can visit the app through the browser the moment he launches it (without writing any handlers yet).
• Redirects the user to the login page when acess is denied to a particular resource.
• Provides a default HTML error page.
• Defaults 'service' to False.
