One good use for this module would be to encode messages that will be sent over TCP, which might fragment the data. You would use lpstream-duplex around an existing net.Socket.
Some example code:
const Lpsd = require("lpstream-duplex");
const lpsd = new Lpsd(inputStream);
// It's just a Duplex stream, you know how to use it.
