added this lil scopes table and better scopes support to pds.js
we're at 5,324 lines
and ~27.5 KB gzipped deployed

a cool feature of the comment model in @grain.social is being able to comment on a particular photo in a gallery, something a lot of other social apps don’t have @goose.art 📸

If anyone wants to try the next version of @grain.social, kind of just letting it simmer on next.grain.social for a bit. it's basically peak quickslice, all views are hydrated via graphql (favs, comments, follows, etc). no complicated lexicon view defs. notifications, create moderation reports, etc

pds.js oauth coming in hot
bringing back the single .js
zero deps besides cloudflare worker stuff
still ironing out stuff (and very basic scopes support) but it works on @pdsls.dev

there's already been some exploration in this space with constellation backed components, but playing around with the same idea for quickslice based web-components. as long as you have an instance deployed with the correct domain authority/namespace and lexicon set, anyone can host their own.

@baileytownsend.dev found an interesting problem! I was noticing that your profile doesn't sync in quickslice based on the current app.bsky.actor.profile lexicon description constraints. popped your record into tools.slices.network/lexicon-validator and sure enough it fails! lol

made this while I was drinking coffee this morning

originally made this a while back with some earlier versions of slices but moving it's proper home in the tools library

you might think I'm crazy but I can't explain how quickly you can build an #atproto app with quickslice and graphql. no codegen, no custom indexes, no view defs, just join and ship!

playing around with cross-lexicon interactions outside of bluesky, create a tangled issue from a 🐛 bug.
You can try it now 👉 tools.slices.network/bugs
You can imagine an #atproto tool like linear interacting with all kinds of apps in the AT ecosystem.

it's a two tool kinda day 🔧 : tools.slices.network/bugs
🐛 a bug tracker for the atmosphere. i literally went from lexicon design to ship in about 2 hours using quickslice.
feel free to report bugs for atmosphere apps! the idea is that it's a place outside of code land for anyone to use

a lexicon validator, created with the same validation library that runs in quickslice (gleam compiles to erlang and js ✨)
great for debugging schema/record validation issues or even for learning how lexicon validation works!

If want to play around with a @teal.fm GraphQL API, you can check out the quickslice instance here fmteal.slices.network. The dashboard for a quickslice instance shows a few simple stats about the AppView and the latest jetstream activity.

Working on an mcp integration with @slices.network so you can just ask the LLM questions about your AppView ie what lexicons it indexes, what queries are available, and even the ability to execute queries via GraphQL. I asked claude to give me a yearly wrapped of plays for @baileytownsend.dev
