Using Nginx with multiple node app into same server - node.js

Question

I am trying to setup nginx conf to work with multiple node app in ythe same server.
I´d like to use:
http://localhost/node-app-01 to access app-01 in the port 3001
http://localhost/node-app-02 to access app-02 in the port 3002 and so on.
But It´s not working.
The error is "http://localhost/css/chunk-006c7b90.0199750b.css net::ERR_ABORTED 404 (Not Found)". I can see the port is not present here.
If I access the app using http://localhost:3001, http://localhost:3002 ... all is ok.
If I run the app using
My folders app structure:
\nginx
\conf
\html
\logs
....
\dev-folder
\dist
| index.html
| \css
| css files
| \js
| js files
|
|\node-app-01 /*run in localhost:3001*/
| \node_modules
| node module files
| \public
| public app files
| package.json
| app.js
| server.js
|\node-app-02 /*run in localhost:3002*/
| \node_modules
| node module files
| \public
| public app files
| package.json
| app.js
| server.js
|\node-app-03 /*run in localhost:3003*/
| \node_modules
| node module files
| \public
| public app files
| package.json
| app.js
| server.js
Nginx conf:
http {
include mime.types;
default_type application/octet-stream;
....
server {
listen 80;
listen [::]:80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
#nginx original server from install
location / {
root html;
index index.html index.htm;
}
location ^~ /node-app-01/ {
rewrite ^/node-app-01/(.*)$ /$1 break;
proxy_pass http://localhost:3001/;
}
location ^~ /node-app-02/ {
rewrite ^/node-app-02/(.*)$ /$1 break;
proxy_pass http://localhost:3002/;
}
location ^~ /node-app-03/ {
rewrite ^/node-app-03/(.*)$ /$1 break;
proxy_pass http://localhost:3003/;
}
}

you can define the upstream in your nginx configuration and if you have websocket try to use ip_hash option
take a look at the example in https tls configuration:
upstream express_servers {
ip_hash;
server 127.0.0.1:8000;
server 127.0.0.1:8001;
server 127.0.0.1:8002;
server 127.0.0.1:8003;
}
server {
listen 443 ssl;
server_name mydomain.com;
error_log on;
ssl_certificate /home/test/ssl/fullchain.pem;
ssl_certificate_key /home/test/ssl/privkey.pem;
client_body_timeout 3m;
client_header_timeout 3m;
client_max_body_size 150m;
send_timeout 3m;
proxy_set_header X-Real-IP $remote_addr; # pass on real client IP
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-NginX-Proxy true;
proxy_ssl_session_reuse off;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_pass http://express_servers;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
