What is this?

This is a tiny package that removes final line endings (CR, LF, CR+LF) from a string.

When should I use this?

This package is rather niche, I found myself repeating this code when working with a lot of markdown.

Install

This package is ESM only. In Node.js (version 14.14+, 16.0+), install with npm:

npm install trim-trailing-lines

In Deno with esm.sh:

import {trimTrailingLines} from 'https://esm.sh/trim-trailing-lines@2'

In browsers with esm.sh:

<script type="module">
  import {trimTrailingLines} from 'https://esm.sh/trim-trailing-lines@2?bundle'
</script>

Use

import {trimTrailingLines} from 'trim-trailing-lines'

trimTrailingLines('foo\nbar') // => 'foo\nbar'
trimTrailingLines('foo\nbar\n') // => 'foo\nbar'
trimTrailingLines('foo\nbar\n\n') // => 'foo\nbar'

API

This package exports the identifier trimTrailingLines. There is no default export.

trimTrailingLines(value)

Remove final line endings from value.

Parameters

valeu

Value with trailing line endings, coerced to string (unknown).

Returns

Value without trailing line endings (string).

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 14.14+ and 16.0+. It also works in Deno and modern browsers.
