WalkthroughAdds a hover-expandable left sidebar with conversation list and deletion, renames and resizes the right preview to “E2B Live Preview” using E2BCodeExecution wired to executeCode('javascript'), makes the preview conditional on showPreview and previewCode, marks a dev dependency optional, and updates build/install commands for Vercel.

🧹 Nitpick comments (7)
src/components/ChatInterface.tsx (7)
52-52: Remove empty lineThis empty line is unnecessary and should be removed to maintain consistent code formatting.
- - const { logger } = Sentry;
210-211: Remove unnecessary empty linesMultiple consecutive empty lines should be reduced to a single line for better code readability.
}, []); - - // Initialize message encryption when user is available
1171-1173: Consider debouncing hover state changesThe sidebar expansion/collapse on hover may trigger too frequently, especially if the user accidentally hovers near the boundary. Consider adding a debounce delay to improve UX.
+ const [hoverTimeout, setHoverTimeout] = useState<NodeJS.Timeout | null>(null); + onMouseEnter={() => setSidebarExpanded(true)} onMouseLeave={() => setSidebarExpanded(false)} + // Alternative with debounce: + // onMouseEnter={() => { + // if (hoverTimeout) clearTimeout(hoverTimeout); + // const timeout = setTimeout(() => setSidebarExpanded(true), 300); + // setHoverTimeout(timeout); + // }} + // onMouseLeave={() => { + // if (hoverTimeout) clearTimeout(hoverTimeout); + // const timeout = setTimeout(() => setSidebarExpanded(false), 200); + // setHoverTimeout(timeout); + // }}
1262-1263: Improve accessibility for rotated textThe rotated "History" text may not be accessible to screen readers and could be difficult to read. Consider using an icon or providing proper ARIA labels.
<div className="flex-1 flex items-center justify-center"> - <div className="-rotate-90 text-[10px] tracking-widest text-gray-500">History</div> + <div className="-rotate-90 text-[10px] tracking-widest text-gray-500" aria-label="Conversation History" role="navigation">History</div> </div>
1631-1631: Responsive breakpoint may be too restrictiveThe live preview panel is hidden on
xlscreens and below (hidden xl:flex). This might be too restrictive - consider showing it onlgscreens as well for better visibility on standard laptop displays.- <div className="hidden xl:flex w-[45%] min-w-[480px] max-w-[780px] border-l border-gray-800/60 bg-[#111] flex-col"> + <div className="hidden lg:flex w-[45%] min-w-[480px] max-w-[780px] border-l border-gray-800/60 bg-[#111] flex-col">
1173-1173: Consider using CSS classes for dynamic widthUsing template literals for dynamic classes can be less performant and harder to maintain. Consider using conditional classes or CSS variables.
- className={`${sidebarExpanded ? 'w-80' : 'w-3'} border-r border-gray-800/60 bg-[#1A1A1A]/90 backdrop-blur-xl flex flex-col transition-[width] duration-300`} + className={`border-r border-gray-800/60 bg-[#1A1A1A]/90 backdrop-blur-xl flex flex-col transition-[width] duration-300 ${sidebarExpanded ? 'w-80' : 'w-3'}`}
153-153: Consider persisting sidebar stateThe sidebar expansion state resets on every component mount. Consider persisting this preference in localStorage for better UX across sessions.
- const [sidebarExpanded, setSidebarExpanded] = useState<boolean>(false); + const [sidebarExpanded, setSidebarExpanded] = useState<boolean>(() => { + const saved = localStorage.getItem('sidebarExpanded'); + return saved ? JSON.parse(saved) : false; + }); + + // Add useEffect to save preference + useEffect(() => { + localStorage.setItem('sidebarExpanded', JSON.stringify(sidebarExpanded)); + }, [sidebarExpanded]);

4-10: If you must keep a suppression, use @ts-expect-error with a reason (but prefer removing it entirely)Using @ts-ignore violates our lint rule and can mask unrelated errors. With the async loader above you can remove the suppression entirely. If you temporarily keep a suppression, use @ts-expect-error and include a short justification.
Example (not recommended if you adopt the async loader):
// @ts-expect-error: lovable-tagger has no types; plugin is optional in dev
4-10: Replace require + @ts-ignore + any with typed async dynamic importThis block violates multiple org rules and ESLint checks: usage of any, @ts-ignore, and require() in ESM. Prefer a typed dynamic import with no ts- directives.
Apply this diff to replace the top-level shim with a typed loader helper:
-let componentTagger: (() => any) | null = null; -try { - // @ts-ignore - optional dev-only dependency - componentTagger = require("lovable-tagger").componentTagger; -} catch (_err) { - componentTagger = null; -} +type ComponentTagger = () => import('vite').PluginOption; +const loadComponentTagger = async (): Promise<ComponentTagger | null> => { + try { + const mod = await import('lovable-tagger'); + return typeof mod.componentTagger === 'function' ? (mod.componentTagger as ComponentTagger) : null; + } catch { + // Optional dependency missing in non-dev/CI: omit plugin gracefully. + return null; + } +};Then make the config async and load conditionally (changes outside the selected lines shown below):
// change this: export default defineConfig(({ mode }) => { // to this: export default defineConfig(async ({ mode }) => { const tagger = mode === 'development' ? await loadComponentTagger() : null; return { // ... plugins: [ react(), tagger ? tagger() : null, VitePWA(/* ... */), ].filter(Boolean), // ... }; });
4-10: Eliminate theanytypeThe declared type (() => any) | null violates strict TS. The proposed approach removes any. If you need a quick interim fix, narrow it to the Vite Plugin type.
Interim minimal alternative (if not adopting the async loader yet):
type ComponentTagger = () => import('vite').PluginOption; let componentTagger: ComponentTagger | null = null;

91-94: Ensure alias '@/’ exists as per repo standardGuideline requires the '@/’ path alias to map to src/. You currently only define '@'. Keep '@' for backward compatibility, but add '@/’ to comply and avoid breaking imports that use '@/…'.
Outside the selected range, add:
resolve: { alias: { '@': path.resolve(__dirname, './src'), '@/': path.resolve(__dirname, './src'), }, },
