xarmian fbea9484d6 fix(web): source-identity guards on the SSE non-sync listeners (BUG-2611) (#1131)
close() does not retract already-queued event tasks, so on a fast
workspace switch a torn-down EventSource's queued events could fire
after the next workspace's source existed. BUG-2540 guarded onopen /
onerror / 'connected'; the remaining listeners had no guard, so
workspace A's stale events dispatched into workspace B's callbacks —
spurious sync passes and cross-workspace item events fanned onto B's
BroadcastChannel, and the sharp member: a stale 'unauthorized' closed
B's LIVE EventSource, flipped the status indicator, and cleared
currentWorkspace over A's auth state, with nothing reconnecting until
a navigation.

Same one-line guard on all four (sync_required, items_bulk_updated,
unauthorized, the ITEM_EVENTS loop); unauthorized additionally closes
its OWN source rather than whatever eventSource currently points at —
the guard has just proven they are the same, and the old shape is what
made the stale path destructive.

Unit harness (BUG-2540's stubbed-EventSource pattern): fast A→B
switch, fire each event type on the torn-down source — zero dispatch
into B — with a live-source control arm per leg so a guard silencing
both cannot pass. All four legs verified failing on the unguarded
build.

Pad Web UI

SvelteKit 2 + Svelte 5 frontend for Pad, compiled to static files and embedded into the Go binary.

Development

npm install
npm run dev          # Dev server at localhost:5173 (proxies API to localhost:7777)
npm run build        # Production build to build/
npm run check        # Type checking with svelte-check

When developing, run the Go backend separately with make dev from the project root.

Building for Production

Do not build in isolation. Always use make build from the project root — this builds the web frontend, then compiles the Go binary with the build output embedded via //go:embed.

Stack

  • Svelte 5 with runes ($state, $derived, $effect)
  • SvelteKit 2 with adapter-static (SPA mode)
  • Tiptap block editor with markdown round-trip
  • svelte-dnd-action for drag-and-drop in board/list views
  • SSE for real-time updates
  • TypeScript throughout
