You will work on an existing **Next.js application** that contains layout/design issues and some configuration bugs. Your task is to identify and resolve these issues, and implement the listed features to enhance the overall user experience. - ---- - -## Tasks - -### 1. Fix Cards Layout & Responsiveness -- Correct the existing card grid layout. -- Improve the overall card design (UI/UX sensibility expected). -- Ensure the page is fully responsive across devices (desktop, tablet, mobile). - -### 2. Add Navbar (Sticky) -- Implement a navigation bar that remains fixed at the top while scrolling. -- Design should be clean and responsive. - -### 3. Optimize Page Load & Performance -- Implement optimizations such as: - - **Lazy loading** for images and non-critical components. - - **Memoization** to avoid unnecessary re-renders. - - **Skeleton loading screens** for better UX during data fetch. - -### 4. Implement Pagination -- Add pagination for the workers listing page. -- Each page should load a suitable number of items (e.g., 9–12 cards per page). - -### 5. Service Filters -- Implement filters for workers based on **price/day** and **type of service**. -- Filters should work seamlessly with pagination. - -### 6. Bug Fixes -- Identify and fix any existing issues in `page.tsx` or configuration files. -- Resolve console warnings or errors. -- Ensure clean and maintainable code following best practices. - -### 7. API Integration -- Currently, the workers’ data is being imported directly from `workers.json`. -- Your task is to **serve this data via /api/wprkers API route**. -- Update the frontend page to fetch this data using `fetch` (or any modern method such as `useEffect`, `useSWR`, or React Query). -- Donot delete the existing data loading logic, comment it out. -- Implement: - - **Loading state** (use skeleton screens). - - **Error handling** (show a friendly error message if API fails). - - **Basic caching or memoization** to prevent redundant calls. - ---- - -## Expectations -- Use **TypeScript** and **Tailwind CSS** consistently. -- Follow **component-driven development** principles. -- Write **clean, readable, and reusable code**. -- Optimize for **performance and accessibility**. -- Maintain **Git commit history** (no single "final commit"). - ---- - -## Deliverables -1. Fork the assignment repo, make changes there. -2. Fill in the Goggle Form with your details for submission. - ---- - -## Evaluation Criteria -- Code quality, readability, and structure. -- UI/UX improvements and responsiveness. -- Correctness of functionality (filters, pagination, sticky navbar, optimizations). -- Debugging and problem-solving approach. -- Git usage and commit practices. -- Handling of API calls, loading states, and error cases. - ---- - -## Notes -- You are free to use libraries like **SWR** or **React Query**, but keep the implementation clean. -- Focus on **real-world production quality code**, not just quick fixes. -- Add comment for any **bug fix or optimization.** -- Document any **extra improvements** you make in your submission. -
