rio-ui 0.10.7rc0

Build modern Websites and Apps just with Python

Rio is an easy to use framework for creating websites and apps and is based entirely on Python. 🐍
You won't need a single line of HTML, CSS, or JavaScript to create beautiful, modern apps.

Tutorial - Examples - Discord - Docs - Source Code

Rio brings React-style components to Python. Pull from a wealth of built-in components and combine them to create your own custom components. Then combine those into entire apps. Best of all, Rio apps can run both locally on your machine and on the web.

Features 🧩

• Modern, declarative UI framework
• 100% Python - Zero HTML, CSS, or JavaScript required
• Over 50 Built-in components for common UI elements, such as rio.Switch, rio.Button, and rio.Text, and many more
• Integrates with modern Python tooling: Thanks to being entirely Type Safe editors can give you instant suggestions and highlight problems right away
• Apps can run both locally and on the web
• Dev tools included
• Open Source & Free forever

Example ⌨️

# Define a component that counts button clicks
class ButtonClicker(rio.Component):
    # Define the attributes of the component. Rio will watch these
    # for changes and automatically update the GUI.
    clicks: int = 0

    # Define a method that increments the click count. We'll later
    # make a button that calls this method whenever it is pressed.
    def _on_press(self) -> None:
        self.clicks += 1

    # Define the `build` method. This method essentially tells rio
    # what a ButtonClicker component looks like. Whenever the state
    # of the ButtonClicker component changes, rio will call its
    # `build` method and update the GUI according to the output.
    def build(self) -> rio.Component:
        return rio.Column(
            rio.Button('Click me', on_press=self._on_press),
            rio.Text(f'You clicked the button {self.clicks} time(s)'),
        )

# Create an App and tell it to display a ButtonClicker when it starts
app = rio.App(build=ButtonClicker)
app.run_in_browser()  # Or `app.run_in_window()` to run as local app!

Installation 🛠️

Rio is available on PyPI, so you can install it using pip:

cd my-project
rio run

You'll have your first app up and running in seconds!
