C++ and Node.js: An Unholy Combination….But Oh So Right

How to create js binding to c/c++ library using nodejs FFI

This is a simple example C/C++ math library binding to Node.JS using addon FFI(foreign feth interface) and web server with express.

If you have an existing library written in C/C++ and you want to use this in a Node.JS application or you want to create an interface binding for javascript, you using node-ffi is a Node.js addon for loading and calling dynamic libraries using pure JavaScript. It can be used to create bindings to native libraries without writing any C++ code.

To install dependency using NPM.

npm install

To Build the project

npm run build

To run the project

npm run start

Cannot build project

Hello,

Could you please provide the node and python version that was used for this project?

I cannot build this project with the following error (npm install):

I have followed the instructions on https://github.com/nodejs/node-gyp but I guesss the project is much older so maybe an older version of python must be used?
Thanks
