What is the most efficient way to pass events/data from erlang processes to nodejs and vice versa? Setting up a tcp socket may be slower or inefficient. I was thinking of doing something native. Both erlang and nodejs provide libraries(NIF) to call C functions but none of them provide an efficient implementation for calling erlang/nodejs functions from C or C++ as far as I know. Please suggest some ideas!</div>
