How to cache correctly in webpack?

Question

JavaScript

In my view: webpack simply creates a hash in the file names, and my task is to cache them in any way.
My caching is done by nginx.
Problem:
I uploaded statics to the server, he gave it to the client, after updating the statics on the server, it is updated on the client. But, when I go to another route of the site (with a page refresh), the update did not happen, again, when the page is updated, the static is also updated, but if I go to some other route again ...
It turns out that the static was saved on each route in a new way ?
nginx:

// переменная
map $sent_http_content_type $expires {
  ~image/  30d;
  text/html  off;
  default  7d;
}

// при отдаче статики:
location / {
  try_files $uri $uri/ /index.html;
  expires $expires;
}

Well, that's all that was in my hands... I didn't interfere anywhere else, except for nginx.
What am I doing wrong?
