nbgradio 0.0.3

nbgradio: convert Jupyter notebooks to static HTML websites with live, embedded Gradio apps.

Installation

pip install nbgradio

Usage

Quickstart

Try nbgradio instantly by running:

nbgradio serve https://github.com/gradio-app/nbgradio/blob/main/test_notebook.ipynb

This will:

• Download this example notebook from GitHub
• Extract the Gradio apps from any cells that contain the Gradio Cell Syntax (#nbgradio comment in the first line)
• Start a local FastAPI server at http://localhost:7860 and launch each Gradio app on a separate page on that server.
• Generate a static HTML site in a /site directory with an index.html that is served at the root http://localhost:7860.

Open your browser to see the result! The notebook contains a simple greeting app that you can interact with.

With Your Own Notebooks

Create a Jupyter notebook with Gradio cells marked with the #nbgradio comment:

#nbgradio name="greet"
import gradio as gr

def greet(name):
    return f"Hello {name}!"

demo = gr.Interface(
    fn=greet,
    inputs=gr.Textbox(label="Your name"),
    outputs=gr.Textbox(label="Greeting")
)

demo.launch()

Then build and serve your notebook with live Gradio apps:

nbgradio serve notebook.ipynb

Or just build the static HTML without starting a server:

nbgradio build notebook.ipynb

More Usage

Multiple Notebooks

nbgradio serve notebook1.ipynb notebook2.ipynb --output-dir my-site

Fragment Mode (for embedding into an existing websites)

nbgradio build notebook.ipynb --fragment --output-dir fragments

Custom Port

nbgradio serve notebook.ipynb --port 8080

Deploying to Hugging Face Spaces 🔥

Deploy your Gradio apps directly to Hugging Face Spaces for public hosting with the --spaces flag:

nbgradio build notebook.ipynb --spaces

This will:

• Prompt you to login to Hugging Face if not already authenticated
• Create Spaces named {username}/{app_name} for each Gradio app extracted from the jupyter notebook
• Deploy each app with proper README and nbgradio tag
• Return URLs pointing to your live Spaces

Why Deploy to Spaces?

Perfect for Static Hosting: This is especially useful if you're deploying your static site to platforms like GitHub Pages or a static Hugging Face Space. These platforms can serve your static HTML, but they can't run Python/Gradio apps. By deploying the interactive components to Spaces, you get:

• Static HTML → Hosted on GitHub Pages/Static Hugging Face Space (fast, free, always on)
• Interactive Apps → Hosted on Spaces with Python runtime and Gradio support
• Integration → Web Components automatically connect the two

Gradio Cell Syntax

Mark cells with #nbgradio name="app_name":

#nbgradio name="calculator"
import gradio as gr

def calculate(operation, a, b):
    if operation == "add":
        return a + b
    elif operation == "multiply":
        return a * b
    return 0

demo = gr.Interface(
    fn=calculate,
    inputs=[
        gr.Radio(["add", "multiply"], label="Operation"),
        gr.Number(label="First number"),
        gr.Number(label="Second number")
    ],
    outputs=gr.Number(label="Result")
)

demo.launch()

Key Points:

• Multiple cells with the same name are concatenated together
• The demo.launch() call is automatically removed

📁 Output Structure

site/
├── index.html              # Main HTML page
├── fragments/              # HTML fragments (with --fragment)
│   └── notebook_name.html
└── static/
    └── style.css           # CSS with syntax highlighting

🎨 HTML Output

Generated HTML includes:

• Markdown cells → Rendered HTML with styling
• Code cells → Syntax-highlighted code blocks
• Gradio cells → Live <gradio-app> Web Components

<gradio-app src="http://localhost:7860/greet" class="gradio-app"></gradio-app>
