This is a dev diary of implementing Filerion, a web-based file manager for online storage (Dropbox, OneDrive, Google Drive, s3 and more).

Today:

added basic s3 support. Unfortunately due to CORS you can’t do S3 requests from the browser (unless you configure the bucket to allow CORS, which no-one does) so had to route the requests via the backend
implemented basic sorting up / down by name and size
show status line with number of directories, files, total size of files etc.
display currently executed actions (like "downloading Dropbox listing")
added remembering configured filesystem in localStorage. Entering s3 credentials every time you re-launch the website would be very annoying so this is important
modern browsers have access to per-website storage that acts like a file system so I’ve added a way to manage that area as well. It was easy to add because it uses the same API as opening local folders
