rio-ui 0.5.9

Build modern Websites and Apps just with Python

🌊 You've arrived at Rio, an easy to use framework for creating websites and apps.

🐍 Rio 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
• Open Source & Free forever

Installation 🛠️

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

pip install rio-ui

Getting Started 🎓

Rio comes with a very helpful command line utility to help you out. Create a new project in one short command:

rio new

You can choose from a variety of built-in templates to get you started. Here's a complete example to create a project based on the tic-tac-toe template:

rio new my-project --type website --template "Tic-Tac-Toe"
cd my-project
rio run

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

How it works 🧠

TODO: Minimal example

from typing import *  # type: ignore
import rio
from openai import AsyncOpenAI

client = AsyncOpenAI()


class DallEPage(rio.Component):
    prompt: str = ""
    image_url: str = ""
    is_loading: bool = False

    async def get_image(self) -> None:
        """Get an image by prompt."""

        self.is_loading = True
        await self.force_refresh()

        if self.prompt == "":
            self.image_url = ""
            self.is_loading = False
            return

        try:
            response = await client.images.generate(

                n=1,
            )
            self.image_url = response.data[0].url

        finally:
