Delimiter Parser

new Delimiter(options: {
delimiter: string | Buffer | number[],
includeDelimiter: boolean

A transform stream that emits data each time a byte sequence is received. To use the Delimiter parser, provide a delimiter as a string, buffer, or array of bytes. Runs in O(n) time.


  • options.delimiter: string|Buffer|number[] The delimiter on which to split incoming data.
  • options.includeDelimiter: boolean Indicate if the delimiter itself should be included in the emitted data. Defaults to false
const SerialPort = require('serialport')
const Delimiter = require('@serialport/parser-delimiter')
const port = new SerialPort('/dev/tty-usbserial1')

const parser = port.pipe(new Delimiter({ delimiter: '\n' }))
parser.on('data', console.log) // emits data after every '\n'
