Cool site! Noticed you are using Svelte 🙏. I normally don’t do web dev, but just started building https://coolr.chat which is using SvelteKit. Pretty good framework.
Ps thanks for the add to nostr devs. 🙏

Just a reminder to checkout https://coolr.chat
Alot of progress made.
- unread channel indicators
- basic mentions by doing @ name or `@name` or pasting in nprofile or npub
- handling of nevent, naddr
- basic IRC like commands with / (more to come soon)
More work to do, but it's coming along! 😃

Ive used fyne a bit and it's actually pretty good, but the biggest negative for me is the lack of customization you can do to the look and feel. They take a "theme" approach and it's a lot more involved than it should be. If it could have more fine grained customizations like SwiftUI, etc it would be quite awesome.

2025-05-02 15:07:39 UTC

Finally a welcome change to iOS AppStore rules.

2025-05-02 02:31:00 UTC

Are there any nostr services like nostr.watch which have an api to get a list of active relays?

2025-05-01 18:17:19 UTC

Working on a basic NIP for ephemeral chat. This is based off of how coolr.chat works and also thanks to @nprofile…x58v starting the basis of this document. I haven't submitted it yet, but just wanted to get the idea started.
https://gist.github.com/ismyhc/e42abc83aa266e622bf253763d52dd6b
You can also checkout https://coolr.chat
Still a work in progress so expect local cache resets as I push out new builds 😃

2025-05-01 14:12:35 UTC

I few changes to Coolr this morning.
If you have it open, please refresh. It will clear your local cache for the breaking changes.
Now using "_" for the default channel so that if you wanted you could filter only by that.
https://coolr.chat

2025-05-01 01:38:59 UTC

Don’t forget to check out Coolr Ephemeral chat. I won’t be around tonight, but hopefully some people will be.
More improvements coming tomorrow!
- shareable channel links
- IRC like commands
- …
https://coolr.chat

2025-04-30 21:34:10 UTC

Some more updates to Coolr
- nip05 should be working better. If for some reason its not showing, you may need to make sure that your kind 0 is available on the relay you are posting to, or at purplepag.es
- when you refresh if you have the older version it will clear you local cache since some breaking changes happened.
https://coolr.chat

2025-04-30 17:58:58 UTC

Okay, made some improvements to my experimental Nostr chat.
It's an ephemeral chat. Kinda like shooting the shit at the water cooler.
- local caching of messages, channels and user metadata.
- nip05 support with verified checkmarks
- Ability to switch to another relay if you'd like.
Still needs a handful of other things. Like ability to easily switch accounts with nostr extension. (if you need to just clear out local storage).
Needs better mobile layout.
Might also add unread counts to the channel list.
Come chat!

Yeah for sure. I think one way would be to use webauthn credentials to encrypt the private key, the it could be store in IndexedDB encrypted. Then any time the user needs to sign an event you could request navigator.credentials.get() which would pull up face/Touch ID to decrypt key and sign. Not perfect but it could be a potential solution.

2025-04-30 02:07:40 UTC

- reply

The biggest problem with PWA imo is that there’s not a great way to store private key. Specifically on iOS you don’t have access to keychain as you would on a native app. I also I am not sure you can use a Safari extension as you normally would from just using Safari.

Will dig deeper on this but at first glance this is more involved than my concept. Not a dig at the author at all, I’m just thinking even more simple.

2025-04-26 19:42:02 UTC

Some basic things to still be done
- Allow connecting to any relay
- local caching of channels you’ve and messages you’ve seen
- nip05 verification
- mobile responsive
- easily sharing links to specific channels via bech32 encoded URLs
- mentions (maybe)
- write a simple NIP/ spec
The idea is to be as simple as possible.

Yeah for sure. Haven't thought about it like that, but a way to spin up quick relay and dispose of it would be cool.

Checkout this experimental prototype I've been working.
Ephemeral chat.
It's super alpha, messy code and not optimized, but I've got some idea's to make it pretty cool.
It's kinda like hanging out at the water cooler. You only hear whats going on if you are there.
Its hard coded to connect to damus relay right now, but will make it so you can connect to any relay that supports ephemeral events.

I still have just a little more work to do, but NIP-29 actually fits very well with this style of messenger.

2024-09-19 23:11:51 UTC

Made a ton of progress on the NIP-29 strfry wire policy code today. I’m hoping to have it complete for testing tomorrow. I just need to also make some minor changes in @npub1see…exkf before I can really test it.
It’s been really fun to learn how strfry works and just the relay side of things in general. It’s also been a blast to write it in V-Lang. Such a fun language. It’s like C with some nice additions. Not to mention it’s super fast. The write policy code is about 700 lines so far. I think it will end up being about 1000 loc.
✌️

2024-09-19 12:15:46 UTC

GM! I've been working on a strfry write policy in v-lang that adds Nip-29 support!
Simply add the binary (or build it yourself) and conf and update your strfry.conf to point to the write policy.
Will share soon 😉

Don’t sleep on vlang. https://vlang.io
I’ve just created 3 vlang modules for doing Nostr stuff.
vsecp256k1 - A wrapper around libsecp256k1 C library.
https://github.com/ismyhc/vsecp256k1
vbech32 - Pure v Bech32 implementation.
https://github.com/ismyhc/vbech32
vnostr - Core Nostr types and functions.
https://github.com/ismyhc/vnostr
All work on MacOS, Linux and windows. Intel/arm
vnostr is still a work in progress and I’ll come back to it later so I can get back to Seer.
If you like C and its speed you’ll love Vlang.

2024-09-03 14:54:45 UTC

Took a little time this morning to figure out how to create a V-lang module that wraps libsecp256k1 so that it can be use in V-lang. Got it working!
Will table it for now and get back to Seer, but if you haven't tried V-lang it's worth playing around with. A C-like language that's super fast with a lot of nice things.
I will post the module repo soon. 😃

Relay devs sleeping on Redis's json document store feature. It's absolutely blazing fast, highly queryable and still open source via Redis Community Edition.
I took some time yesterday to do some testing on it and wow. It's really quite amazing. Simply create an index on all the needed fields and you have powerful querying capabilities. Even tags!
As part of my work on Seer and Nip29 Im also writing a Nip29 focused relay that's easy to run and it will use redisJSON as its db.
Very excited about this.

https://m.primal.net/KTou.mp4 I agree. I started a pretty interesting iOS app a while back which is a secure nostr keystore. Stores your private keys in iOS keychain. Then allows you to open various nostr web clients in wkwebview that support nostr extension. It injects nip-07 support so that the web client can talk to app and request signatures, etc. I also have an extension that will allow you to open a site from safari in the app.  It still needs a lot of love, but you can get the gist of how it would work. I may revisit it sometime.

Love this! I do the same. When my main project is getting bumpy I write something fun to get that win!

Not a fan of RN. Feels like duct tape and fishing wire holding it all together. Dependencies galore. Feels like a security nightmare. Flutter and dart code feels overly verbose to write.
I’m biased because I’m a swift developer, but building with the native platform tools seems to always produce performance and results. Of course this means you need two codebases, however even that will be easier to maintain imo.
I also believe that in terms of UI, you don’t want it to look exactly the same across Android/iOS. Android users expect it to feel like a native Android app and iOS users expect it to feel like an iOS app. The platforms have their own UI nuances.
https://skip.tools is worth looking at though.
Nothing against RN and flutter devs. You do you, just not my cup of tea.

My open heart surgery of Seer yesterday seems to be success so far. I eliminated a ton of complexity around how data is stored and in relay management.

2024-07-31 15:18:20 UTC

Hey! Guess what? SwitData seems to have a bug where you can't use predicates with UInt16. 😅 Thanks Apple!
ffs. Anyways, storing kind as Int works.

2024-07-31 14:04:45 UTC

- reply

I haven't used value transformers before. Im going to look into them though.
Right now I have a handful of models that I create from events as they come in, then store them into SwiftData, but that code is getting overly complicated. So before I dig too deep Im experimenting with something that may or may not work.
Instead of having all these different SwiftData models, Im simply storing a single model for the event. Almost as it would be stored on a relay. One addition to the model is that I serialize the tags into a single special formatted string since trying to use a predicate on nested arrays might get messy.
The idea is that this keeps my data model more simple as well as code path where I store these events.
Then I will use the queries to map the stored event's into their more detailed object where needed.
The unknown I have now is if doing this will cause too much overhead on the UI. I just don't know yet, but my code is early enough that I can try it and if it works as I hope it does it simplifies the code around this a lot.

2024-07-31 13:45:29 UTC

- reply

Yeah, it's missing somethings that would make life easier like conditional update/insert, explicit indexes ( I think it does some automatic indexing) and dealing with migrations seems more complicated than it should be. That said, it integrates so nicely with SwiftUI for me it's hard to not give it a go. Im going to keep going with it for now. The unknown for me is performance. I haven't had any issues there yet, but I haven't pushed it.
My fallback option will probably be Realm which I've used in the past and is quite nice.

2024-07-31 13:36:19 UTC

GM Nostr!
Fighting with SwiftData this morning. When using predicate's for queries, etc it absolutely does not like computed properties. A pain in the ass. I really want SwiftData to work though because it so tightly integrates with SwiftUI.

Very interesting. Right now for Seer Im using SwiftData as the backing local db. Connections and subs are created like normal and then pushed into it. Locally I have live queries to SwiftData. It's actually working well so far, but I haven't really been able to stress it with data yet. So we will see... 😅

2024-07-16 15:05:24 UTC

This is cool. Im interested more how this works at a high level. Do you have a local relay that then talks with all the other relays specified by the user? So note deck simply queries the local relay and as things come in from other relays they are shown?

2024-07-15 15:44:52 UTC

Im going to be focusing on on-boarding for Seer this week. It's crucial that I get this part right. It needs to be easy for new nostr users and experienced nostr users to get up and running.
