We use **Tesseract.js (OCR engine powered by WebAssembly)** to extract text from receipts without any backend or API calls. This means: ✔ Everything runs on-device ✔ No server required ✔ No API keys ✔ Fully offline-capable (PWA-ready) ## ⚙️ What We Build * Camera-based receipt scanning (mobile + desktop fallback) * OCR text extraction using Tesseract.js * Smart parsing of: * Amount * Date * Editable expense review screen * Reuse of existing voice-expense UI system * Angular service-based architecture * GitHub Pages deployment with PWA support ## 🧠 Key Concepts Covered * Browser-based OCR architecture * WebAssembly in real-world apps * Web Workers for performance optimization * Angular state + component reuse patterns * Service Worker caching issues & fixes * Git workflow for feature-based development ## 🚀 Why This Project Matters This is not just a demo — it’s a production-style feature used in: * Expense tracking apps * Fintech tools * AI productivity apps * Offline-first mobile web apps You’ll also see real-world challenges like: * OCR accuracy limitations * Receipt parsing heuristics * GitHub Pages caching issues * Service worker debugging ## 🧰 Tech Stack Angular • Tesseract.js • WebAssembly • Service Workers • GitHub Pages • PWA ## 🎯 Outcome By the end, your app can: 👉 Scan a receipt 👉 Extract structured data 👉 Convert it into an expense automatically Angular OCR, Tesseract.js tutorial, receipt scanner app, AI expense tracker, OCR in browser, WebAssembly tutorial, Angular project, PWA Angular, client side OCR, no backend app, build expense tracker angular, javascript OCR project, web assembly example, web worker angular, angular service worker tutorial, github pages angular deploy, progressive web app tutorial, scan receipt app, convert receipt to expense, automatic expense tracker, AI receipt reader, offline OCR app, mobile camera OCR web app, build in public, AI coding assistant, claude code tutorial, vibe coding, modern web dev project, real world angular app, full stack project without backend Key Highlights & Overview: Mastering <strong>Angular Ocr Example</strong> is essential for modern technical workflows and software skills.
