main.cpp

#include <string>
using namespace emscripten;

class Database {
public:
    Database(std::string databasePath): databasePath{databasePath}{
        printf("Database init \n");
    }
    std::string databasePath;
};

class Connection {
public:
    Connection(Database* database) {
        printf("Connection init\n");
        this->database = database;
    }

    Database* database;
};


EMSCRIPTEN_BINDINGS(my_module) {
    class_<Database>("Database")
        .constructor<std::string>()
        .property("databasePath", &Database::databasePath);
    class_<Connection>("Connection")
        .constructor<Database*>()
        .property("database", &Connection::database);
}

Build command:
emcc main.cpp -o main.js --bind

Error information:

emcc main.cpp -o main.js --bind                                     
main.cpp:30:9: error: expected expression
   30 |         .property("database", &Connection::database);
      |         ^

It can run well without .property("database", &Connection::database);
But don't know how to bind the pointer property.
