Preserve line breaks in angularjs

I have seen this SO question.

My code instead of ng-bind="item.desc" uses {{item.desc}} because I have a ng-repeat before.

So my code:

<div ng-repeat="item in items">
  {{item.description}}
</div>

The item description contains \n for newlines which are not rendered.

How can the {{item.description}} display the newlines easily assuming that I have the ng-repeat above?

Solution 1:

Based on @pilau s answer - but with an improvement that even the accepted answer does not have.

<div class="angular-with-newlines" ng-repeat="item in items">
   {{item.description}}
</div>

/* in the css file or in a style block */
.angular-with-newlines {
    white-space: pre-line;
}

This will use newlines and whitespace as given, but also break content at the content boundaries. More information about the white-space property can be found here:

https://developer.mozilla.org/en-US/docs/Web/CSS/white-space

If you want to break on newlines, but also not collapse multiple spaces or white space preceeding the text (to render code or something), you can use:

white-space: pre-wrap;

Nice comparison of the different rendering modes: http://meyerweb.com/eric/css/tests/white-space.html

Solution 2:

Try:

<div ng-repeat="item in items">
  <pre>{{item.description}}</pre>
</div>

The <pre> wrapper will print text with \n as text

also if you print the json, for better look use json filter, like:

<div ng-repeat="item in items">
  <pre>{{item.description|json}}</pre>
</div>

Demo

I agree with @Paul Weber that white-space: pre-wrap; is better approach, anyways using <pre> - the quick way mostly for debug some stuff (if you don't want to waste time on styling)
