Clone the repository:\n   ```bash\n   git clone https://github.com/your-username/virtualized-masonry-grid.git\n   cd virtualized-masonry-grid\n   ```\n2. Install dependencies:\n   ```bash\n   npm install\n   ```\n### Environment Variables\n\nTo configure the application, create a `.env` file in the root directory by copying the provided `.env.example` file:\n\n```bash\ncp .env.example .env\n```\n\nEnsure to populate the variables in the `.env` file with the required values. These are necessary for the app to function correctly.\n\n---\n\n## Scripts Overview\n\n### Development Server\nStart a local development server:\n```bash\nnpm run dev\n```\n\n### Build\nBundle the app for production:\n```bash\nnpm run build\n```\n\n### Preview\nServe the production build locally using `vite preview`:\n```bash\nnpm run preview\n```\n\nor statically serve the dist folder with `serve`:\n```bash\nnpx serve -s dist\n```\n---\n\n## Testing\n\n### Run Tests\nExecute the test suite with Jest:\n```bash\nnpm run test\n```\n\n### Watch Tests\nRun tests in watch mode for rapid development:\n```bash\nnpm run test:watch\n```\n\n### Test Coverage\nGenerate a code coverage report:\n```bash\nnpm run test:coverage\n```\n\n---\n\n## Linting\nLint the codebase using ESLint:\n```bash\nnpm run lint\n```\n\n---\n\n## Implementation Details\n\nThis project was designed with a strong emphasis on code quality, performance, accessibility, and responsiveness. Below are the key considerations and tools used:\n\n---\n\n#### **Code Quality**\n- **TypeScript:** Ensures type safety and clear contracts for component APIs and utility functions. Centralized type definitions (`src/types`) reduce duplication and improve maintainability.\n- **ESLint \u0026 Prettier:** Used for linting and code formatting to enforce a consistent code style.\n- **Unit Tests:** Added for components, hooks, and utilities.\n- **Lint-staged \u0026 Husky:** Automates pre-commit checks, ensuring clean code is committed to the repository.\n\n---\n\n#### **Performance**\n- **Virtualized Masonry Grid:** Implements virtualization and infinite scrolling to render only visible items in the viewport, reducing memory usage and improving rendering performance.\n   - Includes an optional `throttledScroll` flag for scroll performance tuning.\n- **Image Component:** Implements LQIP (Low-Quality Image Placeholder) with attributes like `fetchPriority` and `decoding`, ensuring optimized image loading.\n- **React Hooks:** Hooks like useCallback, useEffect, and others, minimize unnecessary re-renders by ensuring stable function references and properly handling dependencies.\n- **Vite (with Rollup):** Chosen over CRA (Webpack) for faster builds, optimized output, and a modern development experience.\n- **React Query:** Efficiently manages server state with built-in caching, deduplication, and background refetching.\n\n---\n\n#### **Accessibility**\n- **Semantic HTML:** Ensures proper use of roles and ARIA attributes, such as `role=\"list\"` and `role=\"listitem\"`, for enhanced accessibility.\n- **Keyboard Navigation:** Supports keyboard interaction for key elements like links and buttons.\n- **Semantic HTML Tags:** Uses `\u003cmain\u003e`, `\u003csection\u003e`, `\u003cnav\u003e`,  and `\u003cheader\u003e` to provide a clear structure for screen readers.\n---\n\n#### **Responsiveness**\n- **CSS-in-JS (styled-components):** Simplifies dynamic styling, such as adjusting grid columns based on screen size, while maintaining clear theme integration.\n- **Breakpoints and Columns:** Uses a mobile-first design strategy with inherited column configurations for the masonry grid.\n- **Media Queries:** Implemented mobile-first appriach, via the theme and custom hooks (`useMediaQuery`) for consistent responsiveness.\n\n---\n\n#### **Web Vitals**\n- **Core Web Vitals:**\n   - **Largest Contentful Paint (LCP):** Lazy loading and prioritized resource loading (e.g., `fetchPriority=\"high\"` for key images).\n   - **Cumulative Layout Shift (CLS):** Predefined aspect ratios for images to prevent layout shifts during loading.\n   - **First Input Delay (FID):** Optimized event handlers with `useCallback` to prevent unnecessary re-renders and `debounce` to throttle high-frequency interactions, ensuring faster response times.\n- **Preloading Critical Resources:** Vite’s build optimizations ensure essential chunks are prioritized.\n\n---\n\n#### **Vite Configuration**\n- **Plugins:** Uses `@vitejs/plugin-react-swc` for improved build performance with React and TypeScript.\n- **Code Splitting:** Rollup manual chunks separate common libraries (e.g., React, React Router, React Router Dom, Styled-Components, React Query, Axios) for better caching and faster page loads.\n- **Minification:** Utilizes `esbuild` for faster and smaller builds.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feugenebuhor%2Fvirtualized-masonry-grid","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Feugenebuhor%2Fvirtualized-masonry-grid","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feugenebuhor%2Fvirtualized-masonry-grid/lists"}
