Uploads / Frame

To display content > 2MB in frame cards, first upload the content and then use it in a frame card.

import os
import uuid
from h2o_wave import site, ui
html_content = '''
<!DOCTYPE html>
<h2>Hello World!</h2>
<p>And now for something completely different...</p>
# Create a random filename for our HTML file
# e.g. 6ad24c6f-54ed-41e0-8458-a2efd5e05952.html
html_filename = f'{str(uuid.uuid4())}.html'
# Save HTML content to file
with open(html_filename, 'w', encoding='utf-8') as f:
# Upload HTML file
html_path, = site.upload([html_filename])
# Clean up
# Add a frame card to the page and point it to the HTML file we just uploaded.
# The path will look something like /_f/adb747ae-999f-460b-8050-3d636594d0cf/6ad24c6f-54ed-41e0-8458-a2efd5e05952.html
page = site['/demo']
page['example'] = ui.frame_card(
box='1 1 2 3',
title='An uploaded frame',
