Server-Side Rendering

Server-side rendering allows the content of your PWA store to be available for the search engine and social network bots.

SSR (Server-Side Rendering) provides the content of your PWA store to the search engine and social network bots for the best indexing and display.

ReadyMage instances come with a Prerender.io module pre-installed. You can connect through the User Portal.

If connected, you will be billed based on your usage automatically through your regular monthly invoice. The billing is based on a rate of 1.50$ per 1000 rendered pages with 7-day cache freshness.

Connecting to the ReadyMage account

1. Navigate to User Portal → Project → Selected Instance → Service Management → Server-Side Rendering.

2. Click Connect.

3. Redeploy your instance.

Note: A charge for Prerender.io will be added to your monthly bill.

Disconnecting your Prerender.io account

1. Navigate to User Portal → Instances → Service Management → Server-Side Rendering.

2. Click Disconnect.

3. Redeploy your instance.

Prerender.io Implementation

To allow prerender.io to process bot traffic, ReadyMage infrastructure has the following snippet added to the front-facing Nginx (cache router):

server {
       ...

       # Main application entrypoint
       location / {
        set $prerender_token "";
        
        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-Prerender-Token $prerender_token;
        
        set $prerender 0;
        if ($http_user_agent ~*

            set $prerender 1;
         }
         
         if ($args ~ "_escaped_fragment_") {
            set $prerender 1;
         }
 
         if ($http_user_agent ~ "Prerender") {
            set $prerender 0;
         }

         if ($uri ~* "\.

 set $prerender 0;
         }
 
         # We want to always skip requests to prerender if there are
query arguments. This reduces number of unique urls and keeps the costs
down.
 
          if ($is_args) {
             set $prerender 0;
          }

          if ($prerender = 1) {
             set $prerender_token "inserttoken";
             set $prerender "service.prerender.io";
             rewrite .* /https://$host$request_uri? break;
             proxy_pass http://$prerender;
          }
 
          proxy_pass http://varnish:80;
       }

 
       ...
 }
