Redirect initial URI to ipynb file or directory of ipynb files

[glw]

Description

After starting the python server python -m http.server the URI takes you to http://localhost:8000/lab/index.html which displays as a "file not found". Could the URI redirect to a ipynb file if only one exists or to a directory of ipynb files where the user selects the relevant file?

Reproduce

1. voici build --contents notebooks
2. cd _output
3. start server python -m http.server
4. Go to URI http://localhost:8000/lab/index.html

Expected behavior

URI should take you to directory of ipynb files or straight to displaying a ipynb file.

Context

• voila version: 0.5.0a4
• Operating System and version: Ubuntu 22.04.2 LTS on WSL2
• Browser and version: Microsoft Edge, Version 117.0.2045.31 (Official build) (64-bit)

Troubleshoot Output

Work around is to go to base URI http://localhost:8000. This presents you a directory of ipynb files which can then be opened in browser.

Checked the voici-demo repo and that redirects to the directory correctly.
