import { ReadlineParser } from '@serialport/parser-readline'
//or
const { ReadlineParser } = require('@serialport/parser-readline')

A transform stream that emits data after a newline delimiter is received. To use the Readline parser, provide a delimiter (defaults to \n). Data is emitted as string controllable by the encoding option (defaults to utf8).

Constructor Arguments

interface ReadlineOptions extends TransformOptions {
  /** delimiter to use defaults to \n */
  delimiter?: string | Buffer | number[]
  /** include the delimiter at the end of the packet defaults to false */
  includeDelimiter?: boolean
  /** Defaults to utf8 */
  encoding?: BufferEncoding
}

Example

const { SerialPort } = require('serialport')
const { ReadlineParser } = require('@serialport/parser-readline')
const port = new SerialPort({ path: '/dev/ROBOT', baudRate: 14400 })

const parser = port.pipe(new ReadlineParser({ delimiter: '\r\n' }))
parser.on('data', console.log)
