adjustments

[TGlide]

Here’s a clear, comprehensive set of changes you can paste into your PR description.

---

Summary

• Introduce runed for scroll state & UI reactivity.
• Stabilize message IDs across client/server (pre-seeded UUIDs) to avoid flicker/mismatch during optimistic updates.
• UI/UX polish across chat, navigation, and settings; better hover states, empty states, and smoother scrolling.
• Refactors to remove manual event listeners/observers, reduce DOM juggling, and simplify animations.

What changed

Dependencies

• Add runed@^0.34.0 to app dependencies (package.json / package-lock.json).

  • runed peer deps: svelte ^5.7.0, optional @sveltejs/kit ^2.21.0.
  • Brings dequal, esm-env, and lz-string as deps.

• Lockfile flags: several packages switched from "dev": true to "devOptional": true in package-lock.json (e.g., @sveltejs/kit, @sveltejs/vite-plugin-svelte, inspector, cookie, deepmerge, devalue, kleur, mri, sade, set-cookie-parser, vitefu).

• Lockfile cleanups: removed some "peer": true" markers (dequal, lz-string).

Chat UI & interactions

CopyToClipBoardBtn.svelte

• Visual feedback: shows a checkmark icon (~icons/carbon/checkmark) when copy succeeds.
• Uses a derived Icon that toggles between copy and checkmark based on isSuccess.
• No need for parent components to manage a transient “copied” state.

ChatMessage.svelte

• Edit flow:

  • Replace DOM-level textarea management with a reactive editedContent binding.
  • On submit, retry uses editedContent directly.

• Copy button: remove component-local isCopied wiring—now relies on CopyToClipBoardBtn’s internal success feedback.

• Avatar:

  • MessageAvatar becomes sticky (sticky top-4), slightly larger (size-5) to improve alignment during streaming.

• Edit chip:

  • Always present in layout, uses opacity transitions (opacity-0 group-hover:opacity-100) instead of toggling display to avoid layout shift.

• Minor import tidy-ups & derived values (hasClientThink, etc.).

MessageAvatar.svelte

• Animation refactor:

  • Start animation once and unpause when animating is true; pause on cleanup.
  • Switch <animate> fill to freeze for consistent frame retention.
  • Replace SVG <filter> blur with CSS blur (blur-[1.2px]) for simpler, faster rendering.
  • Remove explicit width/height attributes; sizing via class.

Scrolling controls (moved to runed)

ScrollToBottomBtn.svelte and ScrollToPreviousBtn.svelte

• Replace manual ResizeObserver + scroll listeners with runed’s ScrollState.

• Visibility now derived from arrival state:

  • Bottom button: !scrollState.arrived.bottom (offset 200).
  • Previous button: !scrollState.arrived.top (offset 100).

• Removes custom cleanup logic and reduces event wiring.

Navigation & layout

NavMenu.svelte

• Add empty-state copy: “No conversations yet.” when conversations.length === 0.

ExpandNavigation.svelte

• Adjust alignment from items-center → items-end to better line up with sidebar edge.

routes/+layout.svelte

• Grid class cleanup; fix text-smd → text-sm.
• Reposition ExpandNavigation inside a relative container next to the nav (absolute … -right-2), rather than offsetting from grid columns—prevents overlap and improves responsiveness.
• Use an array-based class expression for readability and fewer string interpolations.

Settings: models list UX

routes/settings/(nav)/+layout.svelte

• Change model entries from clickable <button> with goto() to <a href> anchors—improves semantics and supports open-in-new-tab.

• Introduce masked, fading scroll container (.masked-overflow) for the models list:

  • Gradient masks at top/bottom to hint overflow.
  • Thin, themed scrollbars; overflow handling moved to inner container.

• Minor spacing tweaks (e.g., input wrapper padding) and containment (overflow-hidden on outer, scroll on inner).

Conversation data flow & API

Client-side IDs & tree utilities

• Pre-seed UUIDs on the client and send them to the server:

  • Generate userMessageId and/or assistantMessageId via v4() in routes/conversation/[id]/+page.svelte.
  • Pass these IDs down to creation helpers and request payload.

• Tree helpers (addChildren, addSibling):

  • Now accept optional id on new nodes; otherwise still generate via v4().
  • Type change: NewNode<T> now allows an object with id (Omit<TreeNode<T>, "id"> | TreeNode<T>).

Message updates request

• src/lib/utils/messageUpdates.ts:

  • MessageUpdateRequestOptions gets createdMessageIds.
  • Add created_message_ids to the request form data.

Server

• routes/conversation/[id]/+server.ts:

  • Accept created_message_ids in request body (Zod schema).
  • When inserting user/assistant messages (including retry/continue paths), use provided IDs if present, otherwise generate.
  • Ensures client and server IDs match, preventing re-render churn after streaming begins.

UUID import fix

• routes/conversation/[id]/+page.svelte: change import type { v4 } → import { v4 } to actually call the function.

---

Rationale

• Stability: Pre-seeded IDs keep optimistic UI in sync with server responses, eliminating node re-keying and content flicker.
• Maintainability: runed replaces ad‑hoc scroll/observer code with declarative state—less code and fewer edge cases.
• UX polish: clearer copy feedback, smooth hover exposure (no layout jumps), sticky avatar for reading continuity, better empty states, and a nicer settings scroller.
• Semantics & accessibility: Use anchors for in-app links; improves keyboard and browser behaviors.

---

Testing / QA checklist

• Copy to clipboard

  • Click copy on any message → icon changes to checkmark briefly, then returns to copy.

• Edit flow

  • Click Edit on an assistant message → textarea shows existing content; submit triggers retry with edited content; no flashing or layout jump.

• Scroll buttons

  • With long chat content:

    • Scroll up → “Scroll to previous” appears; clicking jumps to previous message anchor.
    • Scroll down a bit → “Scroll to bottom” appears; clicking jumps to bottom.

• New conversation / empty state

  • When there are no conversations, the sidebar shows “No conversations yet.”.

• Sidebar toggle

  • Toggle button aligns to the right edge of the sidebar; works collapsed/expanded without overlapping content.

• Settings models list

  • List shows fade at top/bottom when overflowed; scrollbar is thin.
  • Each model row is an anchor that navigates (supports open in new tab).
  • “Active” badge still renders correctly.

• Message ID stability

  • During normal send, retry (assistant), and retry with alternate prompt (user):

    • Inspect DOM keys or logs—IDs for the new user/assistant messages remain consistent between client creation and server acknowledgements (no re-keyed nodes).

Notes / Potential impacts

• runed@0.34.0 expects svelte >= 5.7.0 and optionally @sveltejs/kit >= 2.21.0; our versions should satisfy this (verify in CI).
• Lockfile flag changes (devOptional) came from resolver updates; they shouldn’t affect runtime, but call out in case your deploy pipeline treats optional dev deps differently.
• CSS blur replacement in MessageAvatar slightly changes the glow; visually similar but less GPU work.

If you want, I can condense this into a shorter “Release notes” style section as well.
