Two projects inside the same nginx domain?

Question

Nginx

There are two projects
1. Express
2. React
They must be on the same domain in the following ways.
`/` - express
`/admin/*` - react (all internal routes should always go through /var/www/front/user/dist/index.html.)
nginx:

server {
        listen 80;
        listen [::]:80;

        server_name in.devo;
        root /var/www/front/user/dist;

        # react
        location /admin {
                alias /var/www/front/user/dist;
                try_files $uri $uri/ /index.html;

                location ~* /admin/.*\.(?:manifest|appcache|html?|xml|json)$ {
                        sendfile off;
                        expires off;
                }

                location ~* ^/admin/.*\.(?:css|js)$ {
                        try_files $uri =404;
                        expires 1y;
                        access_log off;
                        add_header Cache-Control "public";
                }

                location ~ ^/admin/.+\..+$ {
                        try_files $uri =404;
                }
        }


        # express
        location / {
                add_header Access-Control-Allow-Origin *;
                root /var/www/front/site;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-NginX-Proxy true;
                proxy_pass http://127.0.0.1:3000/;
                proxy_redirect off;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";

                proxy_redirect off;
                proxy_set_header   X-Forwarded-Proto $scheme;
        }

}

In the current implementation, almost everything works fine.
However, if you try to make a request to `/admin/route` it gives you a 404 express error.
How can I make `/admin/***` (without hardcode) always look at the correct index.html?

Answer 1

What exactly is in /var/www/front/user/dist/route ?
1. If static, then it should be downloaded using nginx
2. If include files, then they must be moved to a higher level so that they are not available via http
3. If this request is processed by your application, which gives an error, then, accordingly, you need to fix this bug in the app
