KLayout Web Viewer 
Based on https://github.com/klayoutmatthias/canvas2canvas
From a python virtual environment run:
python -m pip install kweb
export KWEB_FILESLOCATION="/path/to/gds/folder" # or the windows equivalent with set
uvicorn --reload kweb.default:app
KWeb offers two basic apps:
Browser:
A version that provides a version with a file browser for a folder and the kweb viewer for viewing the gds file in that folder.
This can be used by importing the function kweb.browser.get_app and settings the KWEB_FILESLOCATION env variable of passing
fileslocation=<Path object for target folder> to the function. Alternatively there is a default one in kweb.default.app that
will only look for the env variable.
Viewer:
Only enables the /gds/<filename> endpoints, no root path, i.e. no file browser. Available at kweb.viewer.get_app. This version
doesn't provide a listener for the env variable. Use the fileslocation parameter in the function instead.
