vue-nl2br

DEPRECATED — No longer maintained

This package is no longer maintained. Vue 2 reached End of Life on December 31, 2023, and modern CSS makes this component unnecessary in virtually all cases.

Use CSS white-space: pre-wrap; instead. See the Migration section below.

A vue component which turns new lines into line breaks.

Migration

In modern browsers, vue-nl2br can be replaced with a single CSS property: white-space: pre-wrap;.

Before

<nl2br tag="p" :text="`myLine1\nmyLine2`" class-name="foo bar" />

After

<p class="foo bar" style="white-space: pre-wrap;">{{ `myLine1\nmyLine2` }}</p>

Or with a CSS class (assuming text contains \n characters):

.nl2br {
  white-space: pre-wrap;
}

<p class="nl2br">{{ text }}</p>

Why pre-wrap instead of pre?

Historically, white-space: pre; was sometimes considered insufficient because it disables line wrapping (see Issue #7). white-space: pre-wrap; solves this by preserving line breaks while still allowing automatic wrapping for long lines.

Notes on subtle behavior differences

white-space: pre-wrap; is not a strictly bit-for-bit replacement for vue-nl2br. Two minor differences are worth knowing:

• Whitespace preservation: pre-wrap also preserves consecutive spaces and tabs in the source text. vue-nl2br only converts \n into <br> and lets the browser collapse other whitespace as usual.
• Copy/paste behavior: text rendered with <br> and text rendered with pre-wrap may behave slightly differently when users copy the content out of the page.

For the vast majority of use cases — displaying user-generated text with line breaks — these differences are negligible.
