strip-final-newline

Strip the final newline character from a string/buffer

This can be useful when parsing the output of, for example, ChildProcess#execFile(), as binaries usually output a newline at the end. You cannot use stdout.trimEnd() for this as it removes all trailing newlines and whitespaces at the end.

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'
