strip-final-newline

Strip the final newline character from a string/buffer

Can be useful when parsing the output of, for example, ChildProcess#execFile, as binaries usually output a newline at the end. Normally, you would use stdout.trim(), but that would also remove newlines at the start and whitespace.

Install

$ npm install strip-final-newline

Usage

import stripFinalNewline from 'strip-final-newline';

stripFinalNewline('foo\nbar\n\n');
//=> 'foo\nbar\n'

stripFinalNewline(Buffer.from('foo\nbar\n\n')).toString();
//=> 'foo\nbar\n'
