Anywidget

Aug 1, 2024

This week, we're putting the spotlight on anywidget: developed by Trevor Manz, PhD candidate at Harvard, anywidget is a Python library that simplifies creating custom widgets that can be used in interactive programming environments. We strongly believe in anywidget's mission to provides a single interface for developing embeddable widgets inside other applications, such as Panel, Jupyter, and, of course, marimo.

You can also edit this notebook locally with

uvx marimo run --sandbox reactive_quak.py

or

uvx marimo run --sandbox tldraw_colorpicker.py

if you have uv installed, or

marimo run reactive_quak.py

or

marimo run tldraw_colorpicker.py

if you don't have uv installed (you'll need to manually install its dependencies).

To edit the notebook source code, replace run with edit in the above commands. The anywidget community has built some really cool widgets, including quak, an interactive data table implemented that scales to millions of rows and code generates SQL based on UI interactions, and draw data, which lets you draw datasets with your mouse and get them back as dataframes!

We're also excited to announce that we've standardized on anywidget for our plugin API:

• You can now use any anywidget in marimo with just one line of code — just wrap it in mo.ui.anywidget — and it automatically becomes reactive. For example, check out Trevor’s demo at this link to see how marimo brings quak, an interactive data table implemented with anywidget, to life, with selections automatically updating a downstream plot.
• You can now develop custom widgets for marimo; learn more at our docs and anywidget’s

We’re passionate about developer experience, and it’s clear to us that Trevor. is too — anywidget comes with excellent devX for creating widgets with either vanilla JavaScript or frameworks like React and Svelte.

We’re excited to see the innovations that you’ll bring to marimo with anywidget. Happy building!

Note

This project is part of our Community Spotlights collection, where we feature outstanding projects and contributions from the marimo community.

We're thrilled to have Trevor Manz as an active and innovative member of the marimo community!
