Shiny for Python

Tier 1 — covered by CI, releases block on regressions.

Install

• pip install 'pymyio[shiny]'
• Pulls in shinywidgets >= 0.8.0 and shiny >= 1.0.

Minimal example

from shiny import App, ui
from pymyio.shiny import render_myio, output_myio, reactive_brush
from pymyio import MyIO
# ... (point at example_app() for the full pattern)

Reference

• Use pymyio.shiny.example_app() for a copy-pasteable runnable app.

Known gotcha

• Importing shinywidgets anywhere in the process installs a global widget-construction callback.
• pymyio does NOT transitively import shinywidgets.
• Users must explicitly from pymyio.shiny import ... to opt in.
• This protects vanilla Jupyter users who happen to have shinywidgets installed.
