feat(CollabStatus): transport-agnostic live-collaboration status chip by horner · Pull Request #350 · mieweb/ui

horner · 2026-08-01T09:05:34Z

Adds CollabStatus, a connection dot + Live/Connecting… label + "who is editing" summary with a click-to-open panel showing room identity and a rolling event log. The component is transport-agnostic — it renders whatever presence state it is handed.

useYjsCollabStatus binds it to a Yjs y-websocket room in three lines. The doc/awareness/provider are typed structurally, so the library keeps a zero runtime dependency on Yjs (yjs, y-protocols and y-websocket are devDependencies used only by the stories and tests).

Stories include a simulated room (a real Y.Doc + Awareness relayed in memory, so it works with no server and in CI) and a live server room, plus autodocs covering the binding recipe.

Pull request overview

Adds a new transport-agnostic CollabStatus status chip component (with optional debug panel) plus a useYjsCollabStatus hook that binds it to Yjs rooms without introducing a runtime Yjs dependency in the library.

Changes:

Export new CollabStatus component + types and useYjsCollabStatus hook from the public API and build entrypoints.
Add Storybook stories (including an in-memory simulated Yjs room) and Vitest coverage for the component + hook.
Add Yjs-related packages as devDependencies to support stories/tests.

The header's wide connection/projection badge is replaced by two dots: - a projection dot next to the autosave picker (green saved / amber pending), with the wording kept for screen readers; - `CollabStatus` in compact mode (RoomStatus.tsx) whose popup lists the room occupants and a merged activity log: peers joining/leaving, doc updates, sync transitions, field edits, policy changes, proposals, and SQL projection commits. `@mieweb/ui` now builds from the new vendor/ui submodule (mieweb/ui#350), which carries the `compact` + occupants additions this demo needs.

- `compact` prop renders the dot alone; status and editing text move into the trigger's title/accessible name so the chip costs no header space. - The panel gains an "In the room (N)" section listing occupants with their presence colors, with an `alone` fallback. - New `peersTitle`/`alone` labels; `peerLabels()` now returns label+color. - Tests + a `Compact` story.

An app-level condition (unsaved work, a pending save) had no way to reach the header without adding a second dot beside this one, so `attention` lets it share this dot: amber while set, joined into the trigger's accessible name, and headlining the panel. The panel stays narrow by clipping long values (socket URL, log details) to one line, which left them unreadable. Every clipped value now carries its full text in a `title`, and a `Wrap long values` toggle in the panel header unclips all of them at once for the cases where a tooltip is not enough.

src/components/CollabStatus/CollabStatus.tsx:361

This component introduces several arbitrary-value Tailwind classes (e.g. w-[26rem], max-w-[calc(100vw-1rem)], grid-cols-[auto_1fr], grid-cols-[auto_auto_1fr]). These are not currently present in miewebUISafelist (src/tailwind-preset.ts), so Tailwind CSS 3 consumers who rely on the preset safelist (and don’t scan node_modules) may miss critical styles for this panel/layout.

            className={cn(
              'bg-card text-card-foreground border-border fixed z-50 w-[26rem] max-w-[calc(100vw-1rem)]',
              'rounded-lg border p-3 text-xs shadow-xl'
            )}

src/components/CollabStatus/CollabStatus.tsx:300

In compact mode, triggerLabel is built by joining an array that can include attention (typed as React.ReactNode). If attention is a React element, it will be coerced to the string "[object Object]" and end up in aria-label/title, which breaks accessibility names/tooltips.

        attention,
        names.length > 0 && labels.editing(names),
      ]
        .filter(Boolean)
        .join(' — ')

src/components/CollabStatus/CollabStatus.stories.tsx:288

LiveServerDemo keeps error state across serverUrl/roomName changes; once an import/connection fails, the story will continue to render the error even if the next effect run succeeds. Resetting error at the start of the effect avoids a stale error UI.

  React.useEffect(() => {
    let disposed = false;
    let cleanup = () => {};
