About this extension
The fastest way to train your "component-thinking" muscle.

Open any website, toggle the extension ON, and instantly see which HTML elements could be extracted into React components — color-coded with on-hover tooltips.



| Color | Category | Examples |
|-------|----------|----------|
| 🔵 Blue solid border | Layout — big-picture components | <Navbar />, <Header />, <Footer />, <Sidebar /> |
| 🟠 Orange dashed border | Repeated — reusable patterns (3+ siblings) | <Card />, <ListItem />, <ProductCard /> |
| 🟢 Green solid border | Atomic — small building blocks | <Link />, <Button />, <Input />, <Image /> |

  1. Click the Learn React icon in your toolbar.
  2. Toggle Component Highlighting ON.
  3. Browse any website — elements are highlighted in real time.
  4. Hover over any highlighted element to see:
  5. The suggested React component name (e.g., <Navbar />)
  6. A short hint explaining why it should be a component.
  7. A legend panel in the bottom-right corner shows the color key.

  • Works on any website — static HTML, SPAs, React, Vue, Angular, WordPress.
  • Real-time detection — MutationObserver rescans when the DOM changes.
  • Zero configuration — install, toggle, learn.
  • Lightweight & fast — capped at 400 elements for performance safety.
  • Hinglish tooltips — beginner-friendly hints for Indian learners.
  • Privacy-first — NO data collection, NO tracking, NO network requests.

  • Students starting their React journey.
  • Bootcamp learners practicing "thinking in components."
  • Self-taught developers transitioning from vanilla HTML/CSS/JS.
  • Educators and mentors looking for a visual teaching aid.
