Export interactive HTML pages from Jupyter Notebooks

# nbinteract

`nbinteract` is a Python package that creates interactive webpages from Jupyter notebooks. `nbinteract` also has built-in support for interactive plotting. These interactions are driven by data, not callbacks, allowing authors to focus on the logic of their programs.

`nbinteract` is most useful for:

• Data scientists that want to create simple interactive blog posts without having to know / work with Javascript.
• Instructors that want to include interactive examples in their textbooks.
• Students that want to publish data analysis that contains interactive demos.

Currently, `nbinteract` is in an alpha stage because of its quickly-changing API.

## Examples

Most plotting functions from other libraries (e.g. `matplotlib`) take data as input. `nbinteract`'s plotting functions take functions as input.

```import numpy as np
import nbinteract as nbi

def normal(mean, sd):
'''Returns 1000 points drawn at random fron N(mean, sd)'''
return np.random.normal(mean, sd, 1000)

# Pass in the `normal` function and let user change mean and sd.
# Whenever the user interacts with the sliders, the `normal` function
# is called and the returned data are plotted.
nbi.hist(normal, mean=(0, 10), sd=(0, 2.0), options=options)
``` Simulations are easy to create using `nbinteract`. In this simulation, we roll a die and plot the running average of the rolls. We can see that with more rolls, the average gets closer to the expected value: 3.5.

```rolls = np.random.choice([1, 2, 3, 4, 5, 6], size=300)
averages = np.cumsum(rolls) / np.arange(1, 301)

def x_vals(num_rolls):
return range(num_rolls)

# The function to generate y-values gets called with the
# x-values as its first argument.
def y_vals(xs):
return averages[:len(xs)]

nbi.line(x_vals, y_vals, num_rolls=(1, 300))
``` ## Publishing

From a notebook cell:

```# Run in a notebook cell to convert the notebook into a publishable HTML page:
#
# nbi.publish('my_binder_spec', 'my_notebook.ipynb')
#
# Replace my_binder_spec with a Binder spec in the format
#
# Replace my_notebook.ipynb with the name of the notebook file to convert.
#
# Example:
nbi.publish('SamLau95/nbinteract-image/master', 'homepage.ipynb')
```

From the command line:

```# Run on the command line to convert the notebook into a publishable HTML page.
#
# nbinteract my_binder_spec my_notebook.ipynb
#
# Replace my_binder_spec with a Binder spec in the format
#
# Replace my_notebook.ipynb with the name of the notebook file to convert.
#
# Example:
nbinteract SamLau95/nbinteract-image/master homepage.ipynb
```

For more information on publishing, see the tutorial which has a complete walkthrough on publishing a notebook to the web.

## Installation

Using `pip`:

```pip install nbinteract

# The next two lines can be skipped for notebook version 5.3 and above
jupyter nbextension enable --py --sys-prefix widgetsnbextension
jupyter nbextension enable --py --sys-prefix bqplot
```

You may now import the `nbinteract` package in Python code and use the `nbinteract` CLI command to convert notebooks to HTML pages.

## Developer Install

If you are interested in developing this project locally, run the following:

``````git clone https://github.com/SamLau95/nbinteract
cd nbinteract

# Installs the nbconvert exporter
pip install -e .

# To export a notebook to interactive HTML format:
jupyter nbconvert --to interact notebooks/Test.ipynb

pip install -U ipywidgets
jupyter nbextension enable --py --sys-prefix widgetsnbextension

brew install yarn
yarn install

# Start notebook and webpack servers
make -j2 serve
``````
