Naruto Infinite List

A small React + TypeScript + Vite application demonstrating an infinite/virtualized list UI pattern. The app is built with modern frontend tooling and aims to be a concise, easy-to-read example of how to implement infinite scrolling, lazy loading, and efficient list rendering in a TypeScript React codebase.

What this repository contains

• A Vite + React + TypeScript application (primary language: TypeScript).
• Styles (CSS) and a small amount of JavaScript/HTML for the frontend.
• Example implementation of an infinite-scroll list (the project name suggests a Naruto-themed dataset, but the pattern is generic and can be adapted to any paginated data source).

Features

• Infinite/continuous scrolling to load items as the user scrolls.
• TypeScript-first codebase with typed components and utilities.
• Minimal Vite configuration for fast development and builds.
• Small, focused component structure that demonstrates common patterns:
  • Data fetching and pagination
  • Custom hooks for reuse (e.g., useInfiniteScroll or useFetch)
  • Presentational and container components for clear separation of concerns

Tech stack

• React
• TypeScript
• Vite
• CSS (for styling)
• (Optional) Common helpers: fetch APIs, debounce utilities, simple caching

Getting started

Prerequisites:

• Node.js (recommend LTS)
• npm or yarn

Common commands:

• Install dependencies
  • npm install
  • or yarn
• Run development server
  • npm run dev
  • or yarn dev
• Build for production
  • npm run build
  • or yarn build
• Preview production build locally
  • npm run preview
  • or yarn preview
• Lint / format (if configured)
  • npm run lint
  • npm run format

(Adjust commands above to match the repository's actual package.json scripts.)

Code organization (typical)

While exact paths may vary, expect a structure similar to:

• src/
  • main.tsx — app entry point
  • App.tsx — root app / routes
  • components/
    • InfiniteList/ — core list and list item components
    • CharacterCard.tsx — presentational card (if themed)
  • hooks/
    • useInfiniteScroll.ts — intersection observer or scroll listener
    • useFetch.ts — reusable fetch/pagination logic
  • api/
    • clients or adapters for fetching list pages
  • styles/
    • global.css, component css files
  • types/
    • domain and API TypeScript types
  • utils/
    • helpers like debounce, throttle, formatting
• public/ — static assets

This layout keeps presentational components, hooks, API logic, and types separated so the infinite-list behavior is easy to reason about and reuse.

Implementation notes and suggestions

• Infinite scroll can be implemented with:
  • IntersectionObserver on a sentinel element at the end of the list, or
  • Scroll event + threshold logic (less preferred for performance)
• For large lists, consider virtualization (react-window / react-virtual) to improve rendering performance.
• Add loading and error states for better UX when fetching pages.
• Debounce or throttle scroll/fetch triggers to reduce duplicate requests.
• Use TypeScript types for API responses and component props to increase maintainability.
• Testing: add unit tests for hooks and components (React Testing Library + Vitest / Jest).
