18-18:⚠️ Potential issueVerify Next.js version compatibility
The specified version
^15.1.4appears incorrect as Next.js 15 has not been officially released yet. The latest stable version is 14.x.Recommend downgrading to the latest stable 14.x version:
- "next": "^15.1.4", + "next": "^14.1.0",✅ Verification successful
Next.js version 15.1.4 is correct
The specified version matches the latest stable release from the npm registry. No changes needed.

19-20:⚠️ Potential issueCritical: React 19 is not officially released
The upgrade to React 19 (
^19.0.0) and React DOM 19 (^19.0.0) is problematic as React 19 has not been officially released yet. This will cause installation failures.Recommend staying on the latest stable 18.x version:
- "react": "^19.0.0", - "react-dom": "^19.0.0", + "react": "^18.2.0", + "react-dom": "^18.2.0",
24-26: Verify Node.js type definitions compatibilityThe Node.js types version (
^22.10.5) seems to target a future Node.js version. This should align with your project's Node.js runtime version.Consider aligning the type versions with your project's Node.js version to avoid potential type mismatches.

1-1: Consider removing unnecessary React importIn Next.js 13+, the React import is not required for JSX transformation.
-import React from "react";
7-10: Consider adding more font weights for typography flexibilityThe current font configuration only includes weights 400 (normal) and 500 (medium). Consider adding more weights if the design system requires bold (600/700) or light (300) variations.
const urbanist = Urbanist({ - weight: ["400", "500"], + weight: ["300", "400", "500", "600"], subsets: ["latin"], });

11-13: Implement error handling for data fetchingCurrently, the data fetching operations do not handle potential errors from the GraphQL client requests. To improve the robustness of the component, consider adding error handling to manage possible exceptions.
Apply this diff to wrap the data fetching in a try-catch block:
const Community = async () => { + try { const navbarData = await graphQLClient.request<NavbarQueryType>(navbarQuery); const footerData = await graphQLClient.request<FooterQueryType>(footerQuery); const heroData = await graphQLClient.request<HeroQueryType>(heroQuery); + } catch (error) { + // Handle error appropriately + console.error('Error fetching data:', error); + return <div>Error loading page</div>; + } return ( <div>frontend/src/app/earn/page.tsx (1)
12-16: Add error handling for data fetchingTo enhance the reliability of the component, consider adding error handling for the GraphQL data fetching operations. This ensures that any errors during data fetching are managed gracefully.
Apply this diff to include error handling:
const Earn = async () => { + try { const navbarData = await graphQLClient.request<NavbarQueryType>(navbarQuery); const footerData = await graphQLClient.request<FooterQueryType>(footerQuery); const heroData = await graphQLClient.request<HeroQueryType>(heroQuery); const tabsData = await graphQLClient.request<TabSectionQueryType>(tabSectionQuery); + } catch (error) { + // Handle error appropriately + console.error('Error fetching data:', error); + return <div>Error loading page</div>; + } return ( <div>frontend/src/app/page.tsx (1)
12-16: Consider adding error handling for data fetchingAdding error handling to the data fetching operations will improve the component's robustness by managing potential errors from the GraphQL requests.
You can wrap the data fetching in a try-catch block:
const Home = async () => { + try { const navbarData = await graphQLClient.request<NavbarQueryType>(navbarQuery); const partnersData = await graphQLClient.request<PartnersQueryType>(partnersQuery); const footerData = await graphQLClient.request<FooterQueryType>(footerQuery); const heroData = await graphQLClient.request<HeroQueryType>(heroQuery); + } catch (error) { + // Handle error appropriately + console.error('Error fetching data:', error); + return <div>Error loading page</div>; + } return ( <div>frontend/src/app/cooperative/page.tsx (1)
34-38: Ensure consistent data prop naming and access patterns.In the component usages, data props are passed in varying formats—for example,
heroData={heroData.cooperativePageHero}andreportsData={reportData}. For better readability and maintainability, consider standardizing how you pass and access data props across all components.frontend/src/app/pnk-token/page.tsx (1)
41-47: Ensure consistent data prop naming and access patterns.The data props passed to child components use varying structures—for instance,
heroDatais passed directly, whilebuyDatais destructured asbuyData: buyData.pnkTokenPageBuySection. For consistency and clarity, consider standardizing the prop passing approach across all components.frontend/src/app/for-builders/page.tsx (1)
30-36: Ensure consistent data prop naming and access patterns.Data props are being passed with varying destructuring methods, such as
{...{ heroData: heroData.forBuildersPageHero }}and{...{ integrateData: integrateData.forBuildersPageIntegrateSection }}. Consistent prop naming and passing can improve code readability. Consider standardizing this across all components.

description: 'Kleros - The Justice Protocol',
viewport: 'width=device-width, initial-scale=1',
themeColor: '#000000',

frontend/src/app/community/page.tsx (1)
11-12: Consider more explicit props passingUsing object spread for props makes it less clear what props are being passed. Consider explicit prop passing for better maintainability.
- <Hero heroData={heroData.communityPageHero} /> - <CommunitiesSection communities={heroData.communities} /> + <Hero + title={heroData.communityPageHero.title} + description={heroData.communityPageHero.description} + // ... other specific props + /> + <CommunitiesSection + communityList={heroData.communities} + // ... other specific props + />frontend/src/app/earn/page.tsx (1)
14-15: Simplify props spreading syntaxThe current props spreading syntax

21-27: Ensure consistent data fetching strategy between componentsCurrently, the
Navbardata is fetched in theRootLayoutcomponent, while theFootercomponent fetches its own data internally. For consistency and better component encapsulation, consider moving the data fetching logic into theNavbarcomponent.Apply this diff to adjust the data fetching:

Handle potential promise rejection in data fetching
The data fetching logic using .then() does not handle potential errors from the GraphQL request. To ensure robust error handling, consider adding a .catch() block or using try-catch with async/await.
Apply this diff to handle errors:
- .then((result) => ({
+ .then((result) => {
+ return {
socials: result.footerSocialsSection.socials,
sections: result.footerLinksSection.Section,

Avoid using async functions in React functional components
Defining the Footer component as an async function may cause issues when used as a client-side component. In React, functional components should not be async functions because they cannot handle promises returned from render functions. This can lead to unexpected behavior or rendering issues.
Consider fetching the data within a useEffect hook or using server-side data fetching methods provided by Next.js.
Apply this diff to refactor the component:
-const Footer: React.FC = async () => {
+const Footer: React.FC = () => {
+ const [data, setData] = React.useState(null);
+
+ React.useEffect(() => {
+ graphQLClient
+ .request<FooterQueryType>(footerQuery)
+ .then((result) => {
+ setData({
+ socials: result.footerSocialsSection.socials,
+ sections: result.footerLinksSection.Section,
+ cta: result.footerSubscribeCta,
+ });
+ });
+ }, []);
+
+ if (!data) {
+ return null; // Or render a loading indicator
+ }

+ const { socials, sections, cta } = data;📝 Committable suggestion

🧹 Nitpick comments (3)
frontend/src/utils/graphQLClient.tsx (1)
10-12: Add request timeout configuration.The GraphQL client should have a timeout configuration to prevent hanging requests. This is especially important for server-side rendering where long-running requests can impact page load times.
const graphQLClient = new GraphQLClient(endpoint, { headers: { Authorization: `Bearer ${token}` }, + timeout: 10000, // 10 seconds timeout });frontend/src/app/for-builders/page.tsx (1)
22-28: Avoid props spreading for better maintainability.Using the spread operator with props makes it harder to track prop dependencies and can lead to prop drilling. Consider passing specific props instead.
- <Hero {...{ heroData: heroData.forBuildersPageHero }} /> + <Hero heroData={heroData.forBuildersPageHero} /> - <UseCasesSection - {...{ useCasesData: useCasesData.forBuildersPageUseCasesSection }} - /> + <UseCasesSection + useCasesData={useCasesData.forBuildersPageUseCasesSection} + /> - <IntegrateSection - {...{ integrateData: integrateData.forBuildersPageIntegrateSection }} - /> + <IntegrateSection + integrateData={integrateData.forBuildersPageIntegrateSection} + />frontend/src/app/pnk-token/page.tsx (1)
32-39: Inconsistent props spreading patterns.The component uses different styles of props spreading which makes the code less maintainable. Standardize the approach across all components.
- <Hero {...{ heroData }} /> + <Hero heroData={heroData} /> - <BuySection {...{ buyData: buyData.pnkTokenPageBuySection }} /> + <BuySection buyData={buyData.pnkTokenPageBuySection} /> - <TokenNeedSection - {...{ tokenNeedData: tokenNeedData.pnkTokenPageNeedSection }} - /> + <TokenNeedSection + tokenNeedData={tokenNeedData.pnkTokenPageNeedSection} + /> - <TokenomicsSection - {...{ tokenomicsData: tokenomicsData.pnkTokenPageTokenomicsSection }} - /> + <TokenomicsSection + tokenomicsData={tokenomicsData.pnkTokenPageTokenomicsSection} + />

🛠️ Refactor suggestion
Add error handling to the request function.
The request function should include error handling to properly handle and transform GraphQL errors. This will help with debugging and provide better error messages to consumers.

document: RequestDocument | TypedDocumentNode<T, object>,
variables?: object,
) {
- return await graphQLClient.request<T>(document, variables);
+ try {
+ return await graphQLClient.request<T>(document, variables);

Implement proper error handling and follow Next.js data fetching patterns
The current implementation has several issues:
- Missing error handling for failed requests
- Not following Next.js 13+ data fetching best practices
- No loading state management
Consider this implementation using Next.js patterns:
-const Footer: React.FC = async () => {
+// pages/api/footer.ts
+export async function getFooterData() {
+ try {
+ const data = await request<FooterQueryType>(footerQuery);
+ return {
+ socials: data.footerSocialsSection.socials,
+ sections: data.footerLinksSection.Section,
+ cta: data.footerSubscribeCta,
+ };
+ } catch (error) {
+ console.error('Failed to fetch footer data:', error);
+ throw error;
+ }
+}
+
+// components/Footer.tsx
+const Footer: React.FC = () => {
+ const [footerData, setFooterData] = useState<FooterData | null>(null);
+ const [error, setError] = useState<Error | null>(null);
+
+ useEffect(() => {
+ getFooterData()
+ .then(setFooterData)
+ .catch(setError);
+ }, []);
+
+ if (error) return <div>Failed to load footer</div>;
+ if (!footerData) return <div>Loading...</div>;
+
+ const { socials, sections, cta } = footerData;Or better yet, use Next.js 13+ Server Components:
// app/components/Footer.tsx
import { request } from "@/utils/graphQLClient";
async function Footer() {
try {
const data = await request<FooterQueryType>(footerQuery);
const { socials, sections, cta } = {
socials: data.footerSocialsSection.socials,
sections: data.footerLinksSection.Section,
cta: data.footerSubscribeCta,
};
// Your existing JSX here
} catch (error) {
// Error UI
return <div>Failed to load footer</div>;
}
}
