how to change the public static folder route - docker

Question

I was to access my css with nginx from public folder it works totally fine when i open
localhost:8080/css/main
but i want to access it from my express server running on 3000, 8080 is just web pack building this public folder and updating it on change so i want to access this folder with my express running on 3000 not on webpack on 8080
localhost:3000/css/main
i tried couple of things but didn't work so i didn't want to mess more with the file
upstream backend {
server dev-node:3000;
}
upstream webpack {
server dev-webpack:8080;
}
server {
listen 80;
server_name localhost;
root /app/public
#access_log /var/log/nginx/host.access.log main;
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires 1d;
}
location ^~ /(audio|build|images|style) {
autoindex on;
root /app/public;
}
location /api {
proxy_pass http://backend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
location / {
proxy_pass http://webpack;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
location ~ /\.ht {
deny all;
