How to set up nodejs (express) socket.io nginx and have it all on localhost???

Question

JavaScript

Colleagues, good day. Who set up such a stack on the localhost??????
The browser gives an error: GET prototype.localhost/socket.io/socket.io.js net::ERR_ABORTED 404 (Not Found).
in template: config nginx:
<script src="/socket.io/socket.io.js"></script>

server {
  listen 80;
  listen (:):80;

  server_name prototype.localhost;
  root /home/marey/projects/prototype.map;

  error_page 500 502 503 504 /50x.html;

  location = /50x.html {
    root /home/marey/projects/default;
  }

  location / {
    proxy_pass http://prototype.localhost:5000;
        proxy_redirect off;

        proxy_http_version 1.1; 
    proxy_set_header Upgrade $http_upgrade; 
    proxy_set_header Connection "upgrade"; 
  }

  include config/general.conf;
}

general.conf:

location ~* \.(jpg|jpeg|gif|png|ico|css|js|zip|rar|pdf)$ {

  expires off;

}

gzip on;
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_types text/plain text/css text/xml application/json application/javascript application/xml+rss application/atom+xml image/svg+xml;

How to setup on localhost. I understand that the problem is in the nginx configuration. Well, I really don’t want to remove socket.io.
Tell me who knows how to solve the problem. Thank you in advance.

Answer 1

download the finished assembly
on the git in bulk
, you can directly with the front part
, search by keyword for example MEVN (mongo express vue node)

Answer 2

run node server.js in the console
and I don’t see the port in the error, so the server is not enabled
