Python driver for H2O Q / Telesync Realtime Apps
It is designed to make it fast, fun and easy to build low-latency, realtime, collaborative, web-based applications. It ships batteries-included with a suite of form and data visualization components for rapidly prototyping analytical and decision-support applications.
Telesync’s components work in conjunction with the Telesync relay server that facilitates realtime state synchronization between Python and web browsers.
The Telesync relay server is built into H2O.ai Q for enterprise-grade hosting.
Install and update using pip:
pip install -U telesync
from telesync import site, ui # Access the web page at http://localhost:55555/demo page = site['/demo'] # Add some content. page['example'] = ui.markdown_card( box='1 1 2 2', title='Hello World!', content='And now for something completely different.', ) # Save the page page.save()
$ python hello.py
