kweb 2.0.1

KLayout API implementation of gdsfactory

kweb 2.0.1

KLayout Web Viewer

Based on https://github.com/klayoutmatthias/canvas2canvas

Install & Run

Through pypi

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

Advanced Usage

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.

Development

# Clone the repository to your local

Set a folder for kweb to use when looking for gds files
