Nodejs Addons. C++ to JS type conversion

[HungryHippo]

hi, i'm really struggling to work with Nan and conversions of C++ to V8 types.

How would i convert this format ?  std::vector<uint8_t> data; 

info.GetReturnValue().Set(Nan::New<v8::String>(convertedData));

thanks for any help :-)

if (data.empty()) {
info.GetReturnValue().SetEmptyString();
} else {
// Assumes |data| contains valid UTF-8.
const char* chars = reinterpret_cast<const char*>(&data[0]);
info.GetReturnValue().Set(Nan::New(chars, data.size()).ToLocalChecked());
}

thanks Ben, 

I found setting up the addon quite straightforward but all the type conversions of the javascript inputs to c++ and c++ outputs to v8 was the tricky bit.
