PyFyre - The Python Web Frontend Framework

A fast, declarative, and incrementally adoptable Python web frontend framework for building reactive web user interfaces.

Features

Component-based framework. Developers who have experience in using other frontend frameworks should feel quite at home when using PyFyre.
Truly reactive. PyFyre's virtual DOM allows for simple and efficient state management.
Quick navigation. Navigation between pages is quick with PyFyre's single-page application design.
Pythonic code with static typing. Developing with PyFyre is much easier with its type hinting and Pythonic style of coding.
Asynchronous programming. Run non-blocking functions out of the box.
CPython interoperability. Developers can limitedly use CPython packages on the client-side web.
JavaScript interoperability. Allowing developers to leverage NPM packages and integrate with existing JavaScript applications.
Pure Python. Build web apps without ever touching other languages like HTML and JavaScript.
And more!

Example

See the examples directory for more. If you want to quickly test how PyFyre feels or looks like, try our playground! But here is a super simple example. See how easy it is to create a simple Counter app with PyFyre:

from browser import DOMEvent
from pyfyre import render, State
from pyfyre.nodes import Node, Widget, Text, Button


class App(Widget):
    def __init__(self) -> None:
        self.count = State[int](0)
        super().__init__()

    def build(self) -> list[Node]:
        def increment(event: DOMEvent) -> None:
            self.count.set_value(self.count.value + 1)

        def decrement(event: DOMEvent) -> None:
            self.count.set_value(self.count.value - 1)

        return [
            Button(onclick=decrement, children=lambda: [Text("-")]),
            Text(self.count),
            Button(onclick=increment, children=lambda: [Text("+")]),
        ]


render({"/": lambda: App()})
