[Rinisnotarobot]

This pull request implements infinite scrolling for the public articles list using virtual rendering, improving both performance and user experience. It introduces a new cursor-based pagination API, updates the frontend to use a virtualized list, and cleans up the codebase by removing the old paginated articles page. Supporting changes include dependency updates and improved documentation.

Infinite Scroll & Virtualization for Articles

• Implemented infinite scrolling with virtualization:
  • Added VirtualArticleList component using @tanstack/react-virtual to efficiently render large lists of articles with infinite loading support.
  • Updated the articles route (src/routes/_app/articles.tsx) to use the new virtualized list component instead of the old paginated approach.
  • Removed the old ArticlesPage implementation. [1] [2]

Backend & Query Layer Updates

  • Introduced getPublishedArticlesInfiniteFn server function for cursor-based pagination. [1] [2]
  • Added corresponding Zod schema getPublishedArticlesInfiniteSchema and types. [1] [2]
• Added React Query hook usePublishedArticlesInfinite for infinite loading of articles. [1] [2]
• Updated query keys to support infinite lists.

Dependency & Build Improvements

• Added @tanstack/react-virtual and related packages to dependencies and lockfile. [1] [2] [3] [4] [5] [6]
• Added a production start script and improved Docker support:
  • Added start script to package.json.
  • Added .dockerignore and a multi-stage Dockerfile for optimized builds. [1] [2]

Documentation Updates

• Updated README.md to reflect new directory structure, data layer, and route changes. [1] [2]

These changes modernize the articles list with infinite scrolling and virtualization, streamline the codebase, and improve build and deployment workflows.
