Loading external data with thebe-lite/pyodide

[dolsysmith]

I'm building a static page using thebe-lite with the Pyodide backend, following the provided examples. However, I need users of the page to be able to load data from an external source (i.e., a text file from Project Gutenberg), and I understand that Pyodide currently does not have support for urlretrieve or other Python-native networking functionality. I can see how to use JS to load data and pass it to Pyodide as a Pyodide object, but I'm not sure how to do that with the thebe/thebe-lite API.

Is there any documentation to that effect? If not, any suggestions would be welcome.

Thank you!

Ah, I think I found an answer on the jupyterlite repo.

Something like the following seems to work:

from js import fetch

URL = "https://www.gutenberg.org/cache/epub/1200/pg1200.txt"

res = await fetch(URL)
text = await res.text()
print(text[:400])
