Joyful Python Web App development

Appier is an object-oriented Python web framework built for super-fast app development. It's as lightweight as possible, but not too lightweight. It gives you the power of bigger frameworks, without their complexity.

Your first app can be just a few lines long:

import appier

class HelloApp(appier.App):

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

HelloApp().serve()

The same app using the async/await syntax (Python 3.5+) for async execution reads pretty much the same:

import appier

class HelloApp(appier.App):

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

HelloApp().serve()

Running it is just as simple:

pip install appier
python hello.py

For the async version an ASGI compliant server should be used (eg: Uvicorn):

SERVER=uvicorn python hello.py

Your "Hello World" app is now running at http://localhost:8080.

It features the following:

• Object-oriented
• WSGI (Web Server Gateway Interface) compliant
• ASGI (Asynchronous Server Gateway Interface) ready
• Modular, using dynamically loaded parts
• Python 3 compatible
• RESTful request dispatching
• Asynchronous request handling support
• Templating, using Jinja2
• Data model layer, currently supports MongoDB and TinyDB
• Automatic JSON response encoding for fast API development
• Automatic admin interface, using Appier Extras
• Internationalization (i18n) support
• Flexible project configuration
• Out-of-the-box support for multiple WSGI and ASGI servers: Netius, Uvicorn, Hypercorn, Daphne, etc.

For the purposes of rapid web development, Appier goes well with Netius (web-server) and UXF (client-side graphical library) as a whole stack.
