问题
I have a SDK that will communicate with my Scanner device that is written in C++ language. I need to develop an Electron App that can access the Scanner device. I know there are many libraries available for scanner but I want to use this SDK since it will allow me to access full feature of the device and moreover it is provided by the device manufacturer. So, is there any way to implement this. Please suggest me any idea.

You can use the native V8 API for that. You will need to provide a layer over your C++ code and expose it as Javascript entities.

if there's also a C-style interface you could use node-ffi https://github.com/node-ffi/node-ffi

If you're using electron 3 (which in turn uses Node 10), you can use N-API which has great examples on how to wrap a C++ object into a JS object. N-API is stable and supported by Node 10, so it's a pretty good choice over NaN and node-addon-api for the long term.

Here's a repository of examples that proves pretty useful. This one specifically is for wrapping C++ objects. https://github.com/nodejs/abi-stable-node-addon-examples/tree/master/6_object_wrap/napi
