IoT Quiz

Mobile-first personal quiz app for Introduction to Internet of Things (NPTEL), built with Next.js 15 (App Router), TypeScript and Tailwind CSS. Fully client-side; progress, bookmarks and theme are stored in localStorage.

Run

npm install
npm run dev      # http://localhost:3000
npm run build    # production build (deploys to Vercel as-is)

Deploy (Vercel)

Import the repository in Vercel and deploy with the defaults (framework: Next.js, build command next build). No environment variables or backend are needed; all progress is stored in the browser's localStorage.

Adding questions

Quiz content lives in src/data/weeks/week-N.json, separate from the UI:

{ "week": 1, "title": "Week 1", "questions": [
  { "id": "w1-q1", "week": 1, "number": 1, "type": "MCQ",
    "question": "...", "options": ["...", "..."],
    "correct": [1],
    "explanation": "...", "source": "See lecture ..." } ] }

type is MCQ, MSQ or TF; correct holds indices into options. Optional per-option explanations go in src/data/notes/week-N.json as { "w1-q1": ["note for a", "note for b", ...] } (one entry per option, same order). Add a new week by creating its JSON file and listing it in src/lib/data.ts.
