Python driver for H2O Q / Telesync Realtime Apps

Project description

Telesync is a lightweight library for programming interactive web applications entirely in Python (no HTML/Javascript/CSS) required.

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 Q for enterprise-grade hosting.


Install and update using pip:

pip install -U telesync

Hello world

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


$ python
