I'm afraid there's no convenient support for in-process sharing of handles at the moment. What can you do is the following (I'm assuming you have some kind of TCP server that you want to share across threads): 1. (thread A) create your uv_tcp_t server handle (i.e. bind and listen) 2. (thread A) create a uv_pipe_t and bind it to a path. 3. (thread B) connect to the pipe 4. (thread A) send over the server handle with uv_write2() 5. (thread B) receive handle and start listening In case you're interested, [1] is the commit that removed uv_import() and uv_export(). In hindsight, it may have been better to leave them in. Then again, the approach outlined above works and has the benefit that it's intrinsically thread-safe - all the hard work is done by the operating system.
