🧹 Nitpick comments (6)
components/home/TrendingCoins.tsx (1)
70-73: Consider using a stable unique identifier forrowKey.Using index as the row key can cause React reconciliation issues if the trending coins list changes or is reordered. If
TrendingCoinhas a uniqueidproperty, use that instead.🔎 Proposed fix
<DataTable columns={columns} data={trendingCoins.slice(0, 6)} - rowKey={(_, index) => index} + rowKey={(coin: TrendingCoin) => coin.item.id} headerClassName='table-header-cell' headerRowClassName='hover:bg-transparent' bodyRowClassName='table-row-hover' />components/DataTable.tsx (2)
52-55: Remove commented code.Line 54 contains commented-out padding logic. If this conditional padding is not needed, remove the comment to keep the codebase clean.
🔎 Proposed cleanup
<TableCell key={columnIndex} - className={cn( - column.cellClassName - // columnIndex === 0 && 'pl-5' - )} + className={cn(column.cellClassName)} >
28-33: Consider consistent padding between header and body cells.Header cells apply
pl-5to the first column andpr-5to the last column (lines 31-32), but this padding is not applied to body cells (commented out on line 54). This may cause visual misalignment between header and body columns.If the asymmetry is intentional, consider adding a comment explaining the design decision.
Also applies to: 52-55
hooks/useCoinGeckoWebSocket.ts (1)
22-23: Consider extracting thesendhelper to reduce duplication.The
sendhelper function is defined twice (lines 22-23 and lines 87-90) with identical logic. Extracting it to a reusable function would follow the DRY principle.🔎 Proposed refactor
export function useCoinGeckoWebSocket({ coinId, poolId, }: UseCoinGeckoWebSocketProps): UseCoinGeckoWebSocketReturn { const wsRef = useRef<WebSocket | null>(null); const subscribed = useRef<Set<string>>(new Set()); const [price, setPrice] = useState<ExtendedPriceData | null>(null); const [trades, setTrades] = useState<Trade[]>([]); const [ohlcv, setOhlcv] = useState<OHLCData | null>(null); const [isWsReady, setIsWsReady] = useState(false); + + const createSender = (ws: WebSocket) => (payload: Record<string, unknown>) => + ws.send(JSON.stringify(payload)); // WebSocket connection useEffect(() => { const ws = new WebSocket(WS_BASE); wsRef.current = ws; - const send = (payload: Record<string, unknown>) => - ws.send(JSON.stringify(payload)); + const send = createSender(ws); // ... rest of effect }, []); // Subscribe on connection ready useEffect(() => { if (!isWsReady) return; const ws = wsRef.current; if (!ws) return; - const send = (payload: Record<string, unknown>) => - ws.send(JSON.stringify(payload)); + const send = createSender(ws); // ... rest of effect }, [coinId, poolId, isWsReady]);Also applies to: 87-90
components/home/Categories.tsx (1)
71-75: Consider using a stable key for DataTable rows.Using
indexas therowKeycan cause issues if the data order changes or items are added/removed. If categories have a unique identifier (likeidorname), consider using that instead.🔎 Alternative if category has a stable identifier
If
Categoryhas anameoridfield that's unique:<DataTable columns={columns} data={categories} - rowKey={(_, index) => index} + rowKey={(category) => category.name} />app/coins/[id]/page.tsx (1)
119-138: Consider using label as key and validate link before rendering.Line 122 uses index as key, which is acceptable since
coinDetailshas a stable order. However, usinglabelwould be more semantic and resilient to reordering.Additionally, consider checking if the link is not just truthy but also non-empty before rendering the Link component to avoid broken links.

🔇 Additional comments (25)
components/coin-details/TopGainersLosers.tsx (1)
13-13: LGTM! Tailwind v4 important modifier syntax correctly applied.The important modifier has been correctly moved to the end of the utility classes (
border-none!,bg-transparent!,mb-0!), which aligns with Tailwind CSS v4's breaking change requirement.Also applies to: 19-19
components/Header.tsx (1)
10-10: LGTM! Type consistency improved.Moving from inline prop typing to the shared
HeaderPropstype improves consistency across the codebase and aligns with the broader refactoring effort.hooks/useCoinGeckoWebSocket.ts (2)
116-120: LGTM! Good use ofqueueMicrotaskfor state reset.Using
queueMicrotaskto reset state ensures the updates happen after the current synchronous execution completes, preventing potential race conditions during resubscription.
39-49: Add a comment explaining the CoinGecko API message property naming convention.The code correctly implements the CoinGecko WebSocket API design where G2 messages use the "c" property while G3 messages use "ch" property. This is intentional per the API specification, but adding an explanatory comment would help future maintainers understand why different properties are checked:
// CoinGecko API uses different property names per channel: // - CGSimplePrice/G1 and OnchainTrade/G2 use "c" property // - OnchainOHLCV/G3 uses "ch" property (per CoinGecko API spec) if (msg.c === 'C1') { // ... }This applies to lines 39-49, 51-61, and 63-74.
lib/utils.ts (2)
86-122: LGTM! Pagination logic is well-implemented.The
buildPageNumbersfunction correctly handles:
- Small page counts (≤5 pages) by showing all pages
- Large page counts by showing first, last, and pages around current with ellipsis for gaps
- Edge cases like pages 1, 2, second-to-last, and last
The algorithm ensures the current page is always visible with context, and the ellipsis placement logic is correct.
9-31: LGTM! EnhancedformatPriceflexibility.The addition of the
showSymbolparameter allows callers to format numbers without currency symbols when needed, while maintaining backward compatibility with the default behavior.components/ui/pagination.tsx (1)
40-61:PaginationLinkPropsis defined and properly imported.The type is defined in
types.d.ts(line 276) astype PaginationLinkProps = { isActive?: boolean; size?: ButtonSize; } & React.ComponentProps<'a'>;and is correctly referenced in the component. No TypeScript compilation error exists.Likely an incorrect or invalid review comment.
app/coins/page.tsx (3)
2-7: LGTM!The import additions appropriately support the new DataTable-based rendering approach and utility usage.
20-27: Smart pagination approach!The dynamic pagination expansion strategy elegantly handles the API's lack of total count information while providing a smooth user experience.
92-97: Excellent DataTable integration!The DataTable props are correctly configured with a stable rowKey using
coin.id, proper column definitions, and appropriate styling classes.components/CoinsPagination.tsx (2)
12-25: Great refactoring to shared utilities!Extracting pagination logic into
buildPageNumbersand using theELLIPSISconstant improves code reusability and consistency across the codebase.
49-60: Clean pagination link implementation.The direct page value passing and improved active state handling with
isActiveprop simplifies the component logic.types.d.ts (2)
139-145: LGTM on Trade interface expansion!The rename from
TradeDatatoTradewith addedamountandvaluefields provides more complete type coverage for trade data.
256-285: Excellent generic type definitions for DataTable!The generic
DataTableColumn<T>andDataTableProps<T>interfaces provide flexible, reusable typing for the table abstraction, while the new pagination types (Pagination,PaginationLinkProps) standardize pagination across components.components/coin-details/Converter.tsx (1)
12-12: LGTM on import path adjustment.The import path update correctly reflects the component's directory structure relative to the UI components.
components/home/CoinOverview.tsx (1)
3-7: Clean refactoring!The component rename and import path adjustments improve naming consistency and align with the new component structure.
components/home/Categories.tsx (1)
7-28: DataTable implementation looks good!The Categories component correctly fetches data and defines clear column structures. The image rendering for top gainers provides good visual context.
.vscode/settings.json (1)
1-18: Excellent addition for code consistency!The VSCode settings enforce consistent formatting and linting across the team with sensible defaults (Prettier + ESLint auto-fix on save, 2-space indentation, single quotes).
app/page.tsx (2)
3-10: Clean component imports!The refactored imports clearly separate the main components from their fallback counterparts, improving code organization.
16-28: Excellent Suspense boundary implementation!Each home section is properly wrapped with Suspense and paired with its corresponding fallback component, providing smooth loading states while maintaining a clean component structure.
components/home/Fallback.tsx (3)
11-55: LGTM! Well-structured skeleton component.The
CategoriesFallbackcomponent properly mimics the table structure with appropriate skeleton placeholders. Using index as key is acceptable for static skeleton loading states.
57-70: LGTM! Clean skeleton implementation.The
CoinOverviewFallbackprovides an appropriate loading state with proper spacing and minimum height.
72-107: LGTM! Consistent skeleton pattern.The
TrendingCoinsFallbackfollows the same solid pattern as the other fallback components.app/coins/[id]/page.tsx (2)
7-13: LGTM! Imports align with refactoring.The new imports properly support the DataTable-based refactoring and component consolidation.
58-88: The review comment is incorrect. The Ticker interface intypes.d.tsdefines all accessed properties as required (non-optional), and TypeScript enforces type safety at compile time. Accessingticker.trade_url,ticker.market.name,ticker.base,ticker.target,ticker.converted_last.usd, andticker.timestampis safe—incomplete ticker data cannot reach these cell renderers without triggering a type error. The proposed optional chaining fixes are unnecessary and would mask the actual type contract rather than improve safety.Likely an incorrect or invalid review comment.

Add null safety for API data access.
The coinDetails array accesses deeply nested properties and array elements from coinData without null/undefined checks. If the API response is incomplete or has a different structure, this will cause runtime errors.

In app/coins/[id]/page.tsx around lines 25 to 56, the coinDetails array reads
deeply nested properties and array items from coinData without null checks,
which can crash if the API returns missing fields; update each access to use
optional chaining and nullish coalescing (e.g., market_data?.market_cap?.usd ??
defaultValue, market_cap_rank ?? '-', market_data?.total_volume?.usd ??
defaultValue) and guard array accesses with optional chaining for indexes (e.g.,
links?.homepage?.[0] ?? undefined or '-') so values and links default safely
when absent; ensure formatPrice is only called with a defined numeric value or
wrap it so it handles undefined safely.

update it to first check whether price_change_percentage_24h is a finite number

In components/home/Categories.tsx around lines 30 to 55, the code assumes
category.market_cap_change_24h is always a number which can lead to runtime
errors if it's null or undefined; fix by first normalizing the value (e.g.,
const change = category.market_cap_change_24h ?? 0 or guard with typeof check),
compute isTrendingUp = change > 0, use change for the className comparisons and
formatted output, and when the original value is null/undefined render a safe
fallback (e.g., "N/A" or "-" and no trend icon) so you never call
formatPercentage or compare against undefined.

Use a stable unique identifier for rowKey instead of index.
Using array index as the row key causes incorrect reconciliation when trades are prepended (as seen in the WebSocket hook at line 60 of hooks/useCoinGeckoWebSocket.ts). This leads to unnecessary re-renders and potential UI bugs where row content doesn't match its key.
🔎 Proposed fix using timestamp + type as composite key

In components/LiveDataWrapper.tsx around lines 94 to 98, the DataTable is using
the array index as rowKey which breaks reconciliation when trades are prepended
(see hooks/useCoinGeckoWebSocket.ts line 60); change rowKey to a stable unique
identifier such as trade.id if Trade provides one, otherwise compute a
deterministic composite key (e.g. `${trade.timestamp}-${trade.type}` or similar
unique combination) and use that for rowKey so rows maintain identity across
prepends.

5-8: LGTM!The tab configuration is well-structured with appropriate
as constassertion for type safety, and the keys correctly match the API response structure fromgetTopGainersLosers.
10-22: Property mapping looks correct.The helper function correctly maps the API response properties to CoinCard props, and the key prop is properly included. The logic is sound once the type import issue is resolved.
1-3: No issues found. TheTopGainersLosersResponsetype is properly available through thetypes.d.tsambient declaration file included intsconfig.json, which makes it globally accessible without explicit imports.
24-26: Error boundary coverage should be verified at the route segment level rather than at component level.In React 19 with Next.js App Router, errors bubble up to the nearest parent error boundary. Since this is an async server component, server component errors bubble back to the client as serialized error frames, and client-side Error Boundaries (marked with 'use client') can catch these errors at hydration time and render fallback UI without breaking the entire tree. Rather than wrapping at the component level, confirm that an error.js file exists in the route segment containing this component, as Next.js wraps a route segment and its children in an Error Boundary when using the error.js convention, and when a runtime exception is thrown from anywhere in the route segment, the error.js component is triggered.

important modifier '!' is incorrectly placed after class names (e.g.,

20-45: Consider neutral styling for zero values.The current logic treats zero as negative (red), which may not provide the best UX for neutral changes. For example, a 0% change could be styled differently (e.g., gray) to distinguish it from actual losses.
💡 Example: Handle zero values with neutral styling
const stats = [ { label: 'Today', value: livePriceChangePercentage24h, - isUp: isTrendingUp, + isUp: livePriceChangePercentage24h > 0, + isNeutral: livePriceChangePercentage24h === 0, formatter: formatPercentage, valueClassName: 'coin-header-stat-value', showIcon: true, }, // ... similar for other stats ];Then update the rendering logic (lines 81-84) to apply
text-gray-500whenstat.isNeutralis true.Optional: Consider memoizing the stats array.
Since the stats array is recreated on every render, you could wrap it in
useMemoto avoid unnecessary object creation. However, given the component's size and simplicity, this optimization is not critical.

412-474: Consider using a class selector instead of an ID for better reusability.The refactor consolidates converter styles under a scoped
#converterID selector with modern CSS nesting. While this provides clear scoping, ID selectors have high specificity and can only appear once per page, which limits reusability if multiple converter instances are needed in the future.💡 Alternative approach using a class selector
Consider using
.converterinstead of#converterfor lower specificity and reusability:- #converter { + .converter { @apply w-full space-y-5;This maintains the same scoping benefits while allowing multiple converter instances and easier style overrides when needed.

Add error handling for API call and data access.
The component lacks error handling for the async getTopGainersLosers() call and directly accesses topGainersLosers[tab.key] without null checks. If the API fails or returns unexpected data, this will cause the component to crash.
Consider wrapping this component with an error boundary at the parent level, or add defensive checks before accessing the data.

In components/coin-details/TopGainersLosers.tsx around lines 24 to 48, the code
calls getTopGainersLosers() without error handling and directly indexes
topGainersLosers[tab.key], which can crash if the API fails or returns
unexpected data; wrap the async call in a try/catch and handle errors (e.g., set
a local error state and return a simple error/fallback UI or rethrow for an
upstream error boundary), and defensively access data by validating
topGainersLosers and each topGainersLosers[tab.key] (use nullish checks and
default to an empty array before calling .map) so mapping never runs on
undefined.

Invalid HTML: id attribute on repeating component.
CoinCard renders multiple times in grids/lists, but IDs must be unique per HTML document. While CSS #coin-card selectors will match all elements, this violates HTML spec and can break accessibility tools, getElementById(), and anchor navigation.
Use a data-* attribute or class instead:

🧹 Nitpick comments (3)
components/Header.tsx (1)
42-45: Consider using a property instead of string literal for 'Home' check.The
cnutility usage is excellent. However, the string comparisonitem.label === 'Home'could become fragile if the label changes. Consider adding anisHomeproperty to nav items or using a different identifier.💡 Example refactor
If you control the
navItemsstructure, consider adding an identifier:// In lib/constants.ts export const navItems = [ { label: 'Home', href: '/', id: 'home' }, // ... other items ]; // Then use: className={cn('nav-link', { 'is-active': isActive, 'is-home': item.id === 'home', })}components/CoinHeader.tsx (1)
21-43: Excellent refactoring to a data-driven approach.The stats array consolidates the rendering logic and makes it much easier to maintain or extend. The configuration-driven approach with
formatter,showIcon, andisUpfields is clean and flexible.💡 Optional: Improve type safety for the formatter field
Consider adding a type definition for the stats array to ensure type safety:
type StatFormatter = (value: number | null | undefined) => string; interface StatConfig { label: string; value: number; isUp: boolean; formatter: StatFormatter; showIcon: boolean; } const stats: StatConfig[] = [ // ... existing stats ];This ensures the formatter functions have consistent signatures and provides better IntelliSense support.
components/CoinsPagination.tsx (1)
56-56: Consider removing redundantisActiveprop.The
isActiveprop on line 56 duplicates the active state logic already handled by theclassNameon lines 50-55. If thePaginationLinkcomponent doesn't internally depend onisActive, this prop could be removed for cleaner code.

components/Header.tsx (3)
14-15: LGTM!The simplified header structure with direct container classes improves maintainability.
25-25: LGTM!Using a plain
<nav>element is appropriate for semantic HTML.
10-10: LGTM! HeaderProps is properly defined in types.d.ts.The explicit type annotation with the
trendingCoinsproperty and the default empty array value provide both type safety and robustness.components/CoinHeader.tsx (1)
4-4: LGTM: Clean imports and derived state.The imports are appropriate for the refactored approach, and the derived boolean flags (
isTrendingUp,isThirtyDayUp,isPriceChangeUp) clearly express the trending direction for each metric.Also applies to: 7-7, 17-20
components/CoinsPagination.tsx (3)
12-12: LGTM! Good refactoring to centralize pagination logic.The extraction of
buildPageNumbersandELLIPSISto shared utilities improves code reusability and maintainability. Using a namedPaginationtype for props is also a positive change for type consistency across the codebase.Also applies to: 18-18, 25-25
3-3: No compatibility issues found with theuseRouterimport.Next.js 16.0.8 is a valid release. Next.js 16 introduces several breaking changes, version requirement bumps, removals of deprecated features, and changes to default behaviors, but they primarily affect async APIs, image handling, and parallel routes—not the
useRouterimport fromnext/navigation. The CoinsPagination component's import statement is compatible with this version.
43-60: Verify that buildPageNumbers return type and ELLIPSIS are properly typed with string literals.The conditional on line 45 guards the
onClickhandler correctly, but TypeScript type narrowing afterpage === ELLIPSIScheck requires that both values use literal types. IfbuildPageNumbersreturns(number | typeof ELLIPSIS)[]andELLIPSISis a const with a literal type, the code is type-safe. If these use widerstringornumbertypes without proper literal definitions, TypeScript may not narrow correctly and could allowhandlePageChangeto receive an ELLIPSIS value at runtime.app/globals.css (5)
153-153: LGTM! Appropriate layer for component styles.Changing from
@layer utilitiesto@layer componentsis semantically correct since these styles define reusable component blocks rather than single-purpose utilities.
174-226: LGTM! Header and CandlestickChart styles are well-structured.The header navigation and candlestick chart component styles are cleanly organized with proper nesting and correct Tailwind syntax.
228-275: LGTM! CoinCard component styles are correct.The #coin-card component is well-organized with logical sections (header, price-row, stats) and uses correct Tailwind syntax throughout.
659-723: LGTM! CoinHeader and CoinOverview components are well-structured.The #coin-header and #coin-overview component styles are properly organized with correct Tailwind syntax and logical nesting.
768-787: LGTM! Skeleton utilities are properly defined.The skeleton loading state utilities use correct Tailwind syntax and provide good visual feedback during data loading.

In app/globals.css around lines 642 to 657, the Tailwind important modifier is
incorrectly placed after utilities (e.g. size-full!, p-1!, bg-transparent!,
border-b!, border-dark-500!, rounded-none!, data-[state=active]:border-none!,

In app/globals.css around lines 725 to 766 (specifically lines ~759 and ~763),
the Tailwind important modifier is placed after the utility names; change the
invalid "hover:bg-dark-400!" to "hover:!bg-dark-400" and "bg-green-500!" to
"!bg-green-500" so the "!" appears before the utility (or immediately after the
variant prefix) to correctly apply Tailwind's important modifier.

In components/CoinHeader.tsx around lines 76 to 81, the TrendingUp and
TrendingDown icons are rendered without accessibility labels; update both icon
usages to include an aria-label (or title) that describes the meaning (e.g.,
aria-label={`Trending ${stat.isUp ? 'up' : 'down'}`} or a more specific string
like `${stat.label} trending up`) so screen readers can announce them; ensure
the aria-label is applied to both branches of the conditional and keep
aria-hidden off so the label is exposed.
