nbind

nbind

nbind is a bindings generator for Node.js plugins inspired by embind from emscripten. The bindings are built along with your C++ library without requiring any generated code, using C++11 templates and simple declarations.

It's at an alpha stage and many embind features are missing, but for usage instructions much of the embind documentation is appropriate. The included example (available on GitHub, omitted from npm package) illustrates the basic idea, a simple C++ Point class is defined with no JavaScript-related code. Only the following is required to add support for using it from JavaScript:

#include "Binding.h"

using namespace nbind;

NODEJS_BINDINGS(Point) {
    class_<Point>("Point")
        .constructor<>()
        .constructor<double,double>()
        .function("add",&Point::add)
        .function("print",&Point::print);
}

NODE_MODULE(example,Bindings::initModule)

It can then be used like this:

var Point=require('./build/Release/example.node').Point;

var a=new Point(1,2);
var b=new Point(10,20);

a.add(b);

To compile the example, install required packages for both nbind and the example, build and run inside the example directory:

npm install
cd example
npm install
node point.js
