How to cache files so that later there are no problems when updating?

Question

Nginx

I have an index.html on my server which loads all the js and css.
When updating, I simply change the name of the file: *update* And don't cache the index.html file. Is this approach correct?
<script src=/js/fileV1.js></script>
<script src=/js/fileV2.js></script>

Answer 1

Right after update
<script src="/js/file.js?v=1.0.1"></script>
