Sample nginx config for serving a rails API and static frontend like Ember on the same domain...

nginx.conf

daemon off;

worker_processes 4;

events {
  use epoll;
  accept_mutex on;
  multi_accept on;
  worker_connections 1024;
}

http {
  gzip on;
  gzip_disable "MSIE [1-6]\.(?!.*SV1)";
  gzip_comp_level 2;
  gzip_min_length 512;
  gzip_proxied any;
  gzip_vary on;
  gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

  server_tokens off;

  tcp_nopush on;
  tcp_nodelay on;

  log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

  access_log  /var/log/nginx/access.log  main;
  error_log /var/log/nginx/error.log;

  include /etc/nginx/mime.types;
  default_type application/octet-stream;
  sendfile on;

  resolver NGINX_RESOLVER;
  resolver_timeout 5s;

  server {
    server_name _;
    listen 80;
    keepalive_timeout 5;
    root /var/www;
    index index.html;
    port_in_redirect off;

    # client_max_body_size <%= ENV["CLIENT_MAX_BODY_SIZE"] %>;

    location ~ ^/(api|oauth)/ {
      # Use a variable so that nginx keeps resolving the hostname
      set $backend "backend.example.com";

      proxy_pass http://$backend:3000;
      proxy_set_header Real-IP $remote_addr;
      proxy_set_header Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header NginX-Proxy true;
      proxy_ssl_session_reuse off;
      proxy_redirect off;
    }

    location ~* \index.html$ {
      expires -1;
    }

    location ~* \.(ogg|ogv|svgz|mp4|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf|html|txt|htm)$ {
      expires max;
      log_not_found off;
      access_log off;
      add_header Cache-Control public;
      fastcgi_hide_header Set-Cookie;
    }

    location ~* \.(eot|oft|svg|ttf|woff)$ {
      add_header Access-Control-Allow-Origin *;
      expires max;
      log_not_found off;
      access_log off;
      add_header Cache-Control public;
      fastcgi_hide_header Set-Cookie;
    }

    location ~ /\. {
      deny all;
    }

    location / {
      expires -1;

      try_files $uri $uri/ /index.html =404;
    }
  }
}

it's about time to change application/x-javascript to application/javascript.

Hello, In this case the rails will be running on its own server?
