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 a 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 access is denied to a particular resource.
• Provides a default HTML error page.
• Defaults 'service' to False.
