This project implements an OCR (Optical Character Recognition) service using a Node.js and Express backend. It provides a simple, RESTful API to extract text from image files using the Tesseract.js library.
- 📡 REST API: Exposes a
POST /ocrendpoint to handle OCR tasks and aGET /endpoint for health checks. - 🧠 Tesseract.js Powered: Uses the powerful Tesseract OCR engine for text recognition (defaults to English).
- 📷 Image Upload: Handles
multipart/form-dataimage uploads usingmulter. The image is processed directly from memory. - ⚙️ Express Framework: Built with Express.js for easy setup and routing.
- 🌐 CORS Enabled: Includes CORS middleware to support cross-origin requests.
- 🔐 Environment Config: Loads config (e.g.,
PORT) from a.envfile usingdotenv. - ⚡ Async/Await: Fully asynchronous, non-blocking operations.
- 🚨 Error Handling: Middleware for clean error responses and server stability.
