I have found a lot of modbus related npm library but they are all related to polling from other modbus slave, or act as modbus TCP server. I need to simulate the modbus slave, not the poller (act as modbus RTU server)

The server is just waiting for a client to connect. For the connect event to happen you have to start a query from a client. That means you need to have a second serial port connected to your /dev/ttyUSB0 and initiate a Modbus query from it. For that you can use the same library or any other tool like modpoll or QModMaster.

You also need to develop a little bit your server, because right now it does not have any registers defined, so it won't be much use.

Look at the TCP examples, in particular the SimpleServer. As you can see there, you need to define the Modbus registers or coils on your server, something like:
