Build Web Apps in Jupyter Notebook

Mercury allows you to add interactive widgets in Python notebooks, so you can share notebooks as web applications. Forget about rewriting notebooks to web frameworks just to share your results. Mercury offers a set of widgets with simple re-execution of cells.

You can build with Mercury:

Turn your notebook into beautiful Web Apps,
Create interactive Presentations with widgets, you can recompute slides during the show,
Share notebooks as static Websites,
Build data-rich Dashboards with widgets,
Create Reports with PDF exports, automatic scheduling, and email notifications (coming soon),
Serve Python notebooks as REST API endpoints (coming soon).

Mercury features:

add widgets with Python code - no frontend experience needed!
hide or show the notebook's code,
export executed notebook to PDF or HTML,
share multiple notebooks - no limits!
embed notebook on any website,
easy file upload and download from the notebook,
add authentication to notebooks (coming soon),
schedule automatic notebook execution (coming soon).

Widgets

Mercury provides multiple widgets. There are 3 types of widgets:

Input widgets are components that will appear in the sidebar when running the notebook in Mercury. They can be used to provide user input or trigger action in the notebook.
Output widgets help present notebook results to the user and control execution flow.
Custom Widgets - you can use many custom widgets, for example, PyDeck, and Pivot Tables.

## Integrations

Mercury works with virtually every Python package! Among the most important are machine learning libraries such as Scikit-Learn, Pandas, and Seaborn or visualization libraries: Plotly, matplotlib, Vega-Altair, and Ipyvizzu.

Example

Simple code example that creates a widget and displays its value. You can interact with a widget in the Jupyter Notebook. Its value will be updated. However, to see the update in other cells you need to manually execute them.

Import package:

import mercury as mr

Create a Text widget:

name = mr.Text(value="Piotr", label="What is your name?")

Print widget value:

print(f"Hello {name.value}")

Code in Jupyter Notebook

Mercury App

Use Mercury to run notebook as web application. Cells are automatically re-executed after widget change. Mercury re-executes only cells with widget definition and below it. In the example, cells 2 and 3 are re-executed after widget update.
