Toggle Theme (useReducer)

A small React + Vite practice project that demonstrates:

• theme switching with useReducer
• cross-component state sharing with useContext
• fetching latest repository activity from the GitHub API
• responsive side-by-side layout for Theme and Repo panels

Features

• Toggle between Light and Dark themes using a reducer action.
• Share the active theme via ThemeContext.
• Display the latest public event from:
  • rbalogic/toggle-theme-reducer
• Render two panels side by side on desktop and stack on smaller screens.

Tech Stack

• React
• Vite
• JavaScript (JSX)
• CSS variables for theming

Project Structure

src/
  App.jsx           # Reducer state + context provider
  Theme.jsx         # Theme UI and toggle button
  Repos.jsx         # Fetches and renders latest GitHub repo activity
  ThemeContext.js   # Shared React context
  index.css         # Theme variables and responsive layout

How It Works

1. App.jsx manages theme state with useReducer.
2. The active theme (Light or Dark) is provided through ThemeContext.Provider.
3. Theme.jsx consumes context, applies theme classes, and dispatches toggle action.
4. Repos.jsx consumes context and fetches latest repo event from GitHub on mount.
5. index.css applies theme colors and desktop/mobile layout behavior.

Getting Started

1) Install dependencies

npm install

2) Start development server

npm run dev

Then open the local URL shown in the terminal (usually http://localhost:5173).

Available Scripts

• npm run dev - Run development server
• npm run build - Create production build
• npm run preview - Preview production build locally
• npm run lint - Run ESLint (if configured)

Notes

• GitHub API requests in Repos.jsx use public endpoints and can be rate-limited.
• Theme values are title-cased (Light/Dark) and converted to lowercase for CSS class names.
