How to Build a Desktop Barcode, MRZ & Document Scanner with Electron and JavaScript

Web-based vision SDKs are an excellent fit for Electron: they run entirely in a Chromium renderer process, require no native add-ons, and can be distributed as a self-contained desktop application for Windows, macOS, and Linux. The Dynamsoft Capture Vision (DCV) SDK uses WebAssembly under the hood, which makes it a perfect candidate for Electron's sandbox renderer. This tutorial walks you through wrapping the Dynamsoft barcode, MRZ, and document-scanning capabilities in a production-ready Electron shell. You will learn how the Electron process model works, how to grant camera access, how to relax Content-Security-Policy headers for CDN assets, and how to package the app with electron-builder .
