How I Built a Pro QR Scanner with Real-Time Decoding (React + jsQR) 📲⚡ | No-Backend Logic
Building a UI that looks cool is easy, but building a UI that actually works is what gets you hired.
In this video, I’m breaking down the updated Neural QR Reticle from my 2026 Portfolio.
We’ve moved past simple animations and integrated a real decoding engine that processes camera frames at 60FPS.
Technical Highlights:
• Real-Time Frame Processing: Using requestAnimationFrame and Canvas API to analyze video pixels.
• jsQR Integration: Implementing a client-side decoding engine (No API calls, 100% private).
• Smart File Uploads: A secondary fallback that lets users upload QR screenshots directly.
• Contextual UI: Success screens that actually display the 'Decrypted Payload' from the code.
This project proves you can handle complex browser APIs and real-world data processing. Check the link below for the full source code!
