CLI/Standalone Issue

[davramov]

I have been attempting to use the command line (CLI) implementation to open an ngff-zarr folder and view the volume visualization in a standalone webpage. While the regular Jupyter widget works just fine, after multiple attempts I have not been able to get the standalone version to work.

I created a new conda environment with Python==3.10, and I installed itkwidgets using the commands in the documentation:

pip install 'itkwidgets[cli]>=1.0a49'
playwright install --with-deps chromium

I ran the cells in EnvironmentCheck.ipynb to verify the dependencies. I tried launching with iTerm2, the VSCode terminal, and the regular Mac terminal. In each case, I could neither get the terminal viewer to appear nor a URL to connect to the web browser.

Please let me know if you need any additional information, or if there is another method I can try to run in standalone mode. Thanks!

Alternative clunky approach:

• Start a HTTP file server (with CORS enabled) serving your NGFF-ZARR directory
• Then point the JavaScript viewer app at the server with the image URL paramter like this https://kitware.github.io/itk-vtk-viewer/app?rotate=false&image=http://localhost:8082/test-data/my-image.zarr

I have not tested CLI mode in a while. Python packages may have changed which broke things, among other possible issues. Would be great if you had the time to look into it.

Thanks for the help, I was able to get it running using your approach. If I find time I can look into getting the standalone version to work locally.
