= ObjectWrap::Unwrap(args.This()); Then we can access the s _ attribute and use its. append () method: obj->s_->append(s); Finally, we return the current value of the s _ attribute (Use scope. Close again ): return scope.Close(v8::String::New(obj->s_->c_str())); Because the v8: String: New () method can only accept char pointer as the value, we need to use obj-> s _-> c_str () to obtain it. In this case, you should create a build directory in the plug-in folder. Test Now we can test our
