Test and Release Code Coverage

The web server aims to be flexible so it can be use within a Jupyter environment or as a standalone desktop application.

This package is not supposed to be used by itself but rather should come as a dependency of trame. For any specificity, please refer to the trame documentation.

Installing

trame-server can be installed with pip:

pip install --upgrade trame-server
