Sample Nginx config for deployment of Angular.js app

nginx.conf

server { listen  80;
  server_name example.com;
  access_log /var/log/example.com/nginx.access.log;
  error_log  /var/log/example.com/nginx.error.log;
  root /var/www/apps/example.com/public;
  charset utf-8;

  location / {
    rewrite ^ https://$host$request_uri? permanent;
  }
}

server {
  listen        443 ssl;
  server_name  example.com;
  access_log  /var/log/example.com/nginx.access.log;
  error_log   /var/log/example.com/nginx.error.log;
  ssl_certificate       /etc/nginx/ssl/example.com.pem;
  ssl_certificate_key   /etc/nginx/ssl/example.com.key;

  keepalive_timeout 5;
  root /var/www/apps/example.com/dist;
  charset utf-8;

  location ~ ^/(scripts.*js|styles|images) {
    gzip_static on;
    expires 1y;
    add_header Cache-Control public;
    add_header ETag "";

    break;
  }

  location /api1 {
    rewrite ^/api1/(.*) /$1 break;
    proxy_redirect off;
    proxy_pass https://api1.example.com;
    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 https;
    proxy_set_header Authorization $http_authorization;
  }

  location /api2 {
    rewrite ^/api2/(.*) /$1 break;
    proxy_redirect off;
    proxy_pass https://api2.example.com;
    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 https;
    proxy_set_header Authorization $http_authorization;
  }

  location / {
    try_files $uri /index.html;
  }
}

hmm, hit a problem. now it doesn't work. I wanted to be able to handle both uri and query string in the angular app, and also have an api in the subdirectory.

doesn't work though:

location ~ ^/(api) {
    rewrite ^/api/(.*) /$request_uri break;
    index index.php;
    try_files $request_uri $request_uri/ /index.php?$query_string;
}

location / {
    include /etc/nginx/mime.types;
    try_files $uri /index.html?$query_string;
}

plase explain me im newbie on this.

1. are client and server must be on different domain like (client: example.com and server: srv.example.com)
2. i just 1 ssl for 1 domain and not suport for subdomain. if qst no.1 true so i have got 2 ssl to make this work ?
3. our system use nodejs on backend and angularjs on fronted and run under nginx. must i set ssl on client and server ( i have already set ssl on server side)

thanks for your answer

I want to load balance an Multiple Mean App through NGINX. How can I do that?
