Any mobile apps that are just for posting to a single relay? Thinking about setting up a relay at an event and having it at a static IP address. Then having an event App available to connect to for relay things.
fwiw, this would be for https://anarcon.com so probably a really cool group to nostrize
I too would be interested in this
Looking at Primal stack… running a local caching service seems like a great experience.
Going to try this. nostr:npub18ams6ewn5aj2n3wt2qawzglx9mr4nzksxhvrdc4gzrecw7n5tvjqctp424 should come out to AnarCon to see if it works. You like camping, Derek?
Sounds fun but probably too short notice for this 😭
Mobile apps prob not.. I tried it with amethyst and it sort of works if you delete all the relays and turn off global for nostr.band(It will not allow you to delete nostr.band). The rest of the mobile apps also kinda force relays on you.. snort also misbehaves at displaying global feed for a single relay, half the time it shows some other relay or etc..
I am curious if you find one. What I'd like to see is something like nostrrr.com with posting capability (maybe could be added). Or possibly nostrchat.io with some mods.. -or- of I can dig up the little chat popup app that I think nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft wrote a long time ago that could be added to a site as a 'support window' type chat box.. lmk if you find something.
Which one is a PWA? Could totally run it on the same server as the relay.
can't any WebApp be a pwa?
Yea. But I don’t want to figure that out. I’m looking for low lift to do a PoC. Want to hardcore a single relay into an app for a wifi LAN setup. Hoping this is low enough to test tomorrow.
As far as I can tell the only thing that makes an app a PWA is you add it to your home screen. On Android you just click the button top right and say add to home screen.. works for any site.
Nos.social lets you choose a specific relay when you post.
