detect-newline-at-eof

Detect newline at end of file

detect-newline-at-eof is similar to trailing-newline but will also match \n on Windows and \r\n on macOS.

Installation

$ npm install detect-newline-at-eof

Usage

const fs = require('fs')
const detectNewlineAtEof = require('detect-newline-at-eof')

const fileContents = fs.readFileSync('file.txt', 'utf8')
const newlineCharacter = detectNewlineAtEof(fileContents)

console.log(newlineCharacter)
// => \n, \r\n, or null if no newline character at the end was found
