Event bus use case (& intro)

I've got a quasi-use case, implementation target pattern for RDF-CRDT. I've
not caught up with the list archives yet, thought I might as well dump this
here while it's fresh in my mind.

Where I'm coming from: I've been looking at browser apps with two things in
mind - front end for various server-oriented systems; apps I want to use
myself.

## History
A few years back I played around with an architectural pattern I called
"SPARQL Diamonds" for interactions between browser and a SPARQL store. This
was intended for a bunch of different task-specific apps (blog engine,
wiki, outliner, bookmarker...) that all address a common heterogenous
graph. The apps had a browser-local, non-RDF data model. User content from
forms or whatever would be templated into SPARQL UPDATE queries, any pulls
from SPARQL SELECT would be templated from JSON results into the app's
model. Client, server with templaters in between, diamond shape. It worked
nicely for what it was.

More recently I decided to reboot all this. In the interim PWAs have become
a thing, RDF in the browser is viable, etc etc.

## Now
I've wound up sticking together the regular user (me)-oriented bits in to
one app "Squirt" [1], RDF/SPARQL editing in another, "Atuin" [2] and other
bits designed for specific server-ish things I'm working on elsewhere [3].
They use RDFJS/RDF-Ext under the hood. All very much in-progress, nothing
particularly usable right now.

So *anyway*...

## Event Bus
I've been hopping between Node.js and vanilla browser JS (with npm,
webpack, vitest). A mechanism that seemed to make sense is an event bus I
could use in either. So I made a quick & dirty lib - "evb" [4]. Even though
there's very little to it, I've published it as an npm package to try and
keep some consistency across the things I make.

It occurred to me that I was missing a trick with inter-app comms. I
googled RDF CRDT...and here I am.

I'm thinking that a potential app setup would be to use an event bus
internally, with a single source of truth dataset(s) being replicated
across CRDT. From 1.000 metres they do look kinda similar. Thoughts?

I'm Danny Ayers, @danja in some other places. Homepage at [5]. Located in
Italy, dog called Claudio. I've been around semweb tech a while,
occasionally involved in W3C groups. Also have some history around this
other AI, have recently been looking at ways of encouraging symbiosis
between LLMs and the Rather Enormous Global Graph Augmented Environment.

Cheers,
Danny.
