Code's all public, you'll find it here: https://github.com/sdnts/blobs I've learned a _ton_ about streams building this, so I may be an insufferable streams nerd for a while, FYI. Aside: I didn't share as many WIP updates as I wanted to. Going to try and be less critical about sharing semi-formed ideas in the future.

It's built on top of Cloudflare's Durable Objects, which act as relays for your files. I abuse a WebSocket connection and use it as a TCP stream to zooop bytes. Using DOs also means that transfers are fast everywhere on earth -- there is no "central" server!

@panigrc@mastodon.social Whoa this is extremely cool! I didn’t know this existed, thanks for sharing. Definitely a lot more “finished” too :D At a glance I think PairDrop is _actually_ P2P, I saw mentions of a TURN server, and I think I see some WebRTC stuff in there, so that’s a big improvement over what I have. This motivates me to do some bug-squashing and polishing for blob.city though!

Pushed out a bunch of bugfixes to blob.city. Calling it done for now though, getting a little sick of WebSockets 😪

Here's what I did:

• Removed ambiguous characters from the secret alphabet (thanks @kytta@fosstodon.org for the suggestion!)
• Better mobile support
• Support for multiple simultaneous uploads
• Attempted to address session connection stability

Thanks for the phenomenal response, I'm glad so many of you found it interesting / useful!

@jed@mastodon.social Oh yep yep, I’m pretty sure the included “free” limits will eat that up. Negligible either way, like you said!

@jed@mastodon.social Oh, I shouldn’t need to keep a fetch stream open. Currently a “session” Durable Object only coordinates metadata about uploads/downloads. It can hibernate when there’s no activity. When you upload a file, I create a different “tunnel” DO, which lives for as long as the transfer needs. This receives bytes over a separate WS connection and writes them to an HTTP Response stream. I think this DO can be smart enough to receive bytes over an HTTP request as well.

@kytta@fosstodon.org Oh yeah that should totally be doable. I use nanoid with a custom alphabet so I should be able to just get rid of some characters at the cost of a little increase in collision probability.

@jed@mastodon.social Yeah I was thinking about that, I think it makes sense. My gut says it may also be faster, but I’ll have to do some tests.

@jed@mastodon.social Oh er, I may just have been mistaken about that 300MiB number then.
