If you have a PWA, you might want to make sure that the client is using the latest version of it. Here are the steps needed to do this using quasar framework:
1. Make sure that the service-worker.js is not cached by nginx
Add this configuration in your nginx:
location ~ service-worker.js$ {
#add_header X-debug-whats-going-on 3;
add_header Cache-Control "no-cache, no-store";
expires -1;
try_files $uri $uri/ =404;
#/service-worker.js; -> https://serverfault.com/a/505099
}
