Show a value as multi-line text.

text = "abc\n\ndef"

Use CSS.

<div style="white-space: pre-line">
  
</div>

Or you can replace \n with <br> and also use v-html so it sets as innerHTML rather than just as literal \n text. But it has a security concern if you use user-generated data.

text.replace(/(?:\r\n|\r|\n)/g, '<br />');
