I spent yesterday writing a small file uploaded “app” to allow uploading large files to Azure Storage, but without needing to proxy the files being uploaded.
Turns out this is fairly straightforward to do, but finding out how was definitely not the best experience. Figuring out how to use generateBlobSASQueryParameters is probably the best example. (I ended up reading the source code - the docs, even the types... nope.)
