Building JavaScript and WebAssembly ZXing on Windows

  • f you are looking for a barcode SDK for web development, the ideal outcome is to find a pure JavaScript SDK. The pure JavaScript SDK means JavaScript APIs do not rely on any server-side code. However, most of the barcode SDKs are written in C/C++ and Java. They do not have corresponding JavaScript editions. Meanwhile, JavaScript performance is also the bottleneck. Nowadays, with the advent of WebAssembly, all this will change. WebAssembly runs alongside JavaScript, providing with near-native performance in modern web browsers. In this post, let’s see how to build JavaScript and WebAssembly ZXing — the most popular open source barcode SDK — for developing web barcode apps on Windows.
