Hi  
I am aware of Cancan, but does anyone has a very basic/simple example of file upload to start with?

it’s a few steps away from using a file input, and won’t support chunking, but it’s a proof of concept to authorize uploads to an asset canister, write a `foobar.txt` file, and then fetch it

If I were to adapt this code to rust, would I just ignore the .did.d.ts and .did.js files and reorg the file structure a bit and adapt the .mo code to the appropriate lib.rs?

This is such old code now - things should still work but this isn’t how I’d do anything today

Great to know. I did see that it was quite old. I’m trying my best to figure out the asset loading we discussed using icx-asset and ic-certified-asset but am having several issues so I am looking for the simplest examples I can find related to uploading files.
