Replacements for split

readline.createInterface (native, since Node.js v6.6.0)

Example:

import split from 'split'
import { createInterface } from 'node:readline'

const input = fs.createReadStream('file.txt')

const stream = input.pipe(split()) 
stream.on('data', (line) => { 
  fn(line) 
}) 

const lines = createInterface({ input, crlfDelay: Infinity }) 

for await (const line of lines) { 
  fn(line) 
}
