Python & JS micro framework for realtime web UI applications

Sundash

Python & JS micro framework for realtime web UI applications

• ASGI-based -- minimal 3rd party dependencies and clean core part
• Flexible and extensible -- easy to customize, add 3rd party integrations
• Realtime -- operating through websockets bus, client & backend in app
• Crafted with ❤️

Link to project on PyPi: https://pypi.org/project/sundash/

Installation

    pip install sundash

Examples

    python -m examples <num | name>

To run Hello World example:

    python -m examples hello  # passing 01 also works

Available examples:

• 01 hello - show plain HTML string
• 02 buttons - counter with clickable buttons
• 03 clock - realtime clock (scheduler events)
• 04 menu - simple page routing
• 05 search - handling signle form input
• 06 tables - static tables

Client interaction example:

from dataclasses import dataclass

from sundash import App
from sundash import Component
from sundash import on
from sundash.app import ButtonClick

app = App()


class Counter(Component):
    html = '''
        <button id="minus">-</button>
        <b>{{ count }}</b>
        <button id="plus">+</button>
    '''

    @dataclass
    class Vars:
        count: int = 0

    @on(ButtonClick)
    async def on_click(self, event: ButtonClick):
        if 'plus' == event.button_id:
            self.vars.count += 1

        elif 'minus' == event.button_id:
            self.vars.count -= 1

        await self.update_var('count')


app.run_sync(['<h1>🧮 Counter</h1>', Counter])

Server Interaction Example:

import dataclasses as dc
import datetime as dt

from sundash import Component
from sundash import on
from sundash.scheduler import EverySecond
from sundash.scheduler import SchedulerApp

app = SchedulerApp()


now = lambda: dt.datetime.now().strftime('%H:%M:%S')


class Clock(Component):
    html = '<p><b>Time:</b> {{ time }}<p/>'

    @dc.dataclass
    class Vars:
        time: str = dc.field(default_factory=now)

    @on(EverySecond)
    async def update(self, _):
        self.vars.time = now()
        await self.update_var('time')


app.run_sync(['<h1>🕰️ Clock</h1>', Clock])

В чем идея?

Хочу пробрасывать real-time интерфейс к JS либам, чтобы была возможность написать любую веб-морду для любых системных инструментов.

Примеры использования: любые админки, торговые терминалы, дашборды мониторинга, тулзы для аналитики. Все кастомное и интерактивное, что хочется нарисовать, но ты бэкендер и хочешь писать преимущественно на Python с минимальным использованием JavaScript-а, без тяжеловесного инструментария фронтендеров (React и пр).

Development

• Required: python 3.12, poetry, virtualenv
• Install Python dependencies: poetry install --with=dev
• Run local linters: poe q
• Publish package: poetry publish --build
