Add option to output url

[thenewguy]

It would be handy for an additional output option that simply returns the compressed file url. This would allow javascript that expects a string url for lazy loading when needed at runtime.

Yes, I experience the same issue.

A use case I found myself was to only load a script based on given consent:

{% compress js %}
        <script data-privacy-src="{% static 'vendor/vwo/vwo.js' %}" data-privacy-category="marketing"></script>
{% endcompress %}

I'd want a way to output:

<script data-privacy-src="/static/CACHE/js/output.1f96a412198e.js" data-privacy-category="marketing"></script>

Instead of:

<script src="/static/CACHE/js/output.1f96a412198e.js" type="text/javascript"></script> (and then rendering `;` in the js file)

Creating a custom COMPRESS_PRECOMPILER seems a bit complex here.
