Sample code working for me with emcc 3.1.44:
#include <emscripten/bind.h>
using namespace emscripten;
template <class T>
class Foo
{
public:
Foo()
{
m_value = 0;
}
void add (T value)
{
m_value += value;
}
T m_value;
};
EMSCRIPTEN_BINDINGS(main) {
class_<Foo<int>>("Foo_int")
.constructor<>()
.function("add", &Foo<int>::add)
.property("value", &Foo<int>::m_value)
;
}
Sample use code runs in node 20.5.0:
let Module = require('./main.js');
Module().then((main) => {
let foo = new main.Foo_int();
console.log(`foo.value is ${foo.value}`);
console.log(`calling foo.add(15)`);
foo.add(15);
console.log(`foo.value is ${foo.value}`);
process.exit(0);
});
Makefile:
main.js : main.cpp
emcc -lembind -o main.js -O1 -s MODULARIZE=1 main.cpp
clean :
rm -f main.wasm
rm -f main.js
test :
node test.js
