How to set up nginx reverse proxy with multiple node apps - node.js

Question

I have two Vue.js apps that I want to run on the same domain (e.g., https://localhost:8080/app1 and https://localhost:8080/app2). Both apps run in separate docker containers, and i have set up a third docker container running nginx with a reverse proxy in order to have ssl.
I am able to visit the apps at the wanted locations, but there are some resources missing (images, fonts etc). I realize that my nginx server looks for them at https://localhost:8080/my_resource, but I can't figure out how to forward these to the correct locations (i.e., https://localhost:8080/app1/my_resource, and similar for app2).
I've tried using the "try_files" directive in nginx, like so:
location / {
try_files $uri $uri/ http://app1:8080 http://app2:8080
}
but it does not work.
Here is my nginx config file
server {
listen 80;
listen [::]:80;
server_name localhost;
return 301 https://$server_name$request_uri;
}
# Change the default configuration to enable ssl
server {
listen 443 ssl;
listen [::443] ssl;
ssl_certificate /etc/nginx/certs/my_app.crt;
ssl_certificate_key /etc/nginx/certs/my_app.key;
server_name localhost;
server_tokens off;
proxy_set_header Host $host;
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 $scheme;
location / {
if ($http_referer = "https://localhost:8080/app1/") {
proxy_pass http://app1:8080;
break;
}
if ($http_referer = "https://localhost:8080/app2/") {
proxy_pass http://app2:8080;
break;
}
}
location /app1/ {
proxy_pass http://app1:8080/;
}
location /app2/ {
proxy_pass http://app2:8080/;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
And this is my docker-compose
version: "3.6"
services:
app1:
image: "app1"
expose:
- "8080"
command: ["serve", "-s", "/app/app1/dist", "-l", "8080"]
app2:
image: "app2"
expose:
- "8080"
command: ["serve", "-s", "/app/app2/dist", "-l", "8080"]
nginx:
image: "nginx"
ports:
- "8080:443"
depends_on:
- "app1"
- "app2"
Thanks for any input :)

After a lot of trial and error, I found a solution. I do not think this is the optimal solution, but it's working. Here is my nginx configuration:
# Pass any http request to the https service
server {
listen 80;
listen [::]:80;
server_name localhost;
return 301 https://$server_name$request_uri;
}
# Configure the ssl service
server {
listen 443 ssl;
listen [::443] ssl;
ssl_certificate /etc/nginx/certs/my_app.crt;
ssl_certificate_key /etc/nginx/certs/my_app.key;
server_name localhost;
server_tokens off;
proxy_set_header Host $http_host;
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;
location / {
proxy_intercept_errors on;
error_page 404 = #second;
proxy_pass http://app1:80;
}
location #second {
proxy_pass http://app2:80;
}
location /app1/ {
rewrite ^/app1(.*) /$1 break;
proxy_pass http://app1:80;
}
location /app2/ {
rewrite ^/app2(.*) /$1 break;
proxy_pass http://app2:80;
}
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
