node.js - How to read correctly with serialport in node js? - Stack Overflow

I cannot test this end to end (no arduino anywhere near), but since serialport seems to implement a Readable stream, I'd try using scramjet like this:

const {StringStream} = require('scramjet');

serialport.on('open', () => console.log('open');
serialport.pipe(new StringStream) // pipe the stream to scramjet StringStream
    .lines('\n')                  // split per line
    .each(                        // send message per every line
        data => io.sockets.emit('message',data)
    );

Scramjet would sort the readline issue for you.

I tested this code with the serial port device that uses RS-232 protocol. Its advantage is that you don't need install the third package from npm.

var recVal = '';
mySerial.on('data', function(data) {
  if(data.indexOf('\n') != -1) {
    io.emit('serial:data', {
      value: recVal
    });
    console.log("Data: ", recVal.toString());
    recVal = '';
  } else {
    recVal = recVal.concat(data);
  }
});
