VDOM

Why use VDOM

• Write Declarative Pythonic layouts.
• Create headings, prose, images, and more common user interface items with user-friendly declarative statements.
• Render the layout in Jupyter frontends, such as nteract and JupyterLab.
• Serialize the layout for rehydration and later use in your web app.

Check out the power of VDOM

Create layouts by writing and running Python code. Let's see an example below to create and display a heading, styled prose, and a GIF:

from IPython.display import display
from vdom.helpers import h1, p, img, div, b

display(
    div(
        h1('Our Incredibly Declarative Example'),
        p('Can you believe we wrote this ', b('in Python'), '?'),
        img(src="https://media.giphy.com/media/xUPGcguWZHRC2HyBRS/giphy.gif"),
        p('What will ', b('you'), ' create next?'),
    )
)

Voila!

Your example created a layout and served it below:

Now Incredibly Declarative

Can you believe we wrote this in Python?

What will you create next?

Getting started

Install the Python package

pip install vdom

Usage

First, import vdom.helpers for headings, text, and images:

from vdom.helpers import h1, p, img, div, b

Create a layout using the VDOM helpers in Python code. Here's an example code layout block:

my_pretty_layout = div(
    h1('Our Incredibly Declarative Example'),
    p('Can you believe we wrote this ', b('in Python'), '?'),
    img(src="https://media.giphy.com/media/xUPGcguWZHRC2HyBRS/giphy.gif"),
    p('What will ', b('you'), ' create next?'),
)

To display the layout, use IPython's display method:

from IPython.display import display


display(my_pretty_layout)

The full example, including rendered output, is found above.
