@sam-untapt Change your browser's user agent string (there are extensions for this) to look like a bot, then try the request. The pre-render shouldn't be hit if you're browsing normally.

Working w/ a hosting provider, we couldn't use the above nginx.conf as is. (Restricted to what we can add within a single location block.) Below is the alternative config for inside a location{} block -- not server{}.
Note Our case is not for an SPA, and therefore we removed the if around _escaped_fragment.

proxy_set_header X-Prerender-Token YOUR_TOKEN;  
# Using prerender or not as a variable forces DNS resolution since nginx caches IPs and doesn't play well with load balancing
set $prerender 0;

# Prerender if it's a search bot that doesn't support JavaScript AND the URL is SPA/JavsScript-rendered

  # Old Google-recommended URL parameter to flag SPA
  if ($args ~ "_escaped_fragment_") {
	set $prerender 1;
  }
  # A specific URL that you know is JS-rendered
  if ($uri ~* "^/api-reference") {
	set $prerender 1;
  }
}

# Don't prerender for the prerender bot's own user agent though
if ($http_user_agent ~ "Prerender") {
  set $prerender 0;
}
# Don't prerender media files (they don't contain JavaScript)

  set $prerender 0;
}

set $prerenderprotocol "http";
set $prerenderservice "http://service.prerender.io";

if ($http_x_forwarded_proto = 'https') {
  set $prerenderprotocol "https";
  set $prerenderservice "https://service.prerender.io";
}

# Resolve using Google's DNS server to force DNS resolution and prevent caching of IPs

# Do the proxy if the request met the tests
if ($prerender = 1) {
  rewrite .* /$prerenderprotocol://$host$request_uri? break;
  proxy_pass $prerenderservice;
}

I tried with the follow configuration and it didn't work.
Prerender.io page stays with the message "We haven't seen a request with your Prerender token yet."
Obviously I replaced YOUR_TOKEN with mine

Hey, I just read ajax-crawling and the usage of escaped_fragment is deprecated: https://developers.google.com/webmasters/ajax-crawling/docs/specification

I guess
if ($args ~ "escaped_fragment") {
set $prerender 1;
}
could be removed from the gist then!?

celiovasconcelos · 2018-05-13T20:37:41Z

Why try_files?

Using try_files the location @prerender will never be fired!
I was looking the following behaviour:

If any page is accessed from the browser, nginx serve it statically/locally. If that page is accessed from some crawler, it's served by the proxy.

The official snippet seems not to do that.

Am I crazy?

jindrichbartek · 2018-07-07T22:20:17Z

From "Deprecating our AJAX crawling scheme" (https://webmasters.googleblog.com/2017/12/rendering-ajax-crawling-pages.html)

Given these advances, in the second quarter of 2018, we'll be switching to rendering these pages on Google's side, rather than on requiring that sites do this themselves. In short, we'll no longer be using the AJAX crawling scheme.

So what do you think? Did you guys do some tests with "escaped_fragment" condition?

mindtonic · 2018-07-11T13:06:00Z

+1 to @jeerbl for pointing out that this config file is missing Google Plus. The Google+ Snippet Fetcher User Agent is:

Google (+https://developers.google.com/+/web/snippet/)

For my part I added it to my config file UserAgent regex as developers\.google\.com

Also, if you want to use the Structured Data Testing Tool, you will want to add Google-Structured-Data-Testing-Tool to the regex as well.

Final example:

if ($http_user_agent ~* "baiduspider|twitterbot|facebookexternalhit|rogerbot|linkedinbot|embedly|quora link preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator|developers\.google\.com|Google-Structured-Data-Testing-Tool") {
  set $prerender 1;
 }

maxklenk · 2018-07-20T14:58:45Z

Please add redditbot and Discordbot to the list of user agents.

ddereszewski · 2018-07-27T20:27:24Z

if we use proxy for caching requests can we use proxy_cache_bypass based on user agent?

The goal is that any refresh request made by prerender always takes latest version of the content. Any suggestions?

theChumpus · 2018-08-22T15:35:43Z

@ddereszewski

You may have already found a solution for this but I just ran into this too. Rather than cache based on user-agent (which didn't seem efficient as there are lots of possible UA strings), I use the same $prerender variable as the input to proxy_cache_bypass.

Edit:
Also added proxy_no_cache $prerender so that the response is not added to the cache in these cases either.

dimitarz · 2018-12-24T07:34:40Z

I tried adding this config and it didn't work right away because of my try_files:

location / { try_files $uri @prerender $uri/ =404; }

I ended up having to remove $uri/ =404 and it worked, but now non-existent pages returned index.html! I don't want this behavior, and narrowed it down to removing that pesky

if ($prerender = 0) { rewrite .* /index.html break; }

Why does this even exist here? Totally confusing.

For anybody having issues setting up their own pre-render server with NGINX and/or getting 502 errors.

Check your NGINX HTTPS and HTTPS logs for more information on the issue.

if "502 Bad Gateway" error throws on centos api url for api gateway proxy pass on NGINX, run following command to solve the issue:
sudo setsebool -P httpd_can_network_connect 1

kaioken · 2020-01-14T17:29:47Z

If you have any issue with AWS loadbalancer https redirect you will need to force it to https

#rewrite .* /$scheme://$host$request_uri? break;
rewrite .* /https://$host$request_uri? break;

I was using Prerender with Wordpress and HTTPS protocol and I had to consult Prerender.io to get it to work. I had to remove $http_user_agent ~ "Prerender" condition to be able to use try_files as can be seen in this gist https://gist.github.com/torava/324af0b11fafe6c5e1cc8e02121af608

roarkmccolgan · 2020-07-23T12:26:49Z

for my nginx config I was unable to include a try_files in an if statement:
It fails with "not allowed"

if ($prerender = 1) {
            
            #setting prerender as a variable forces DNS resolution since nginx caches IPs and doesnt play well with load balancing
            set $prerender "service.prerender.io";
            rewrite .* /$scheme://$host$request_uri? break;
            proxy_pass http://$prerender;
        }
        if ($prerender = 0) {
            try_files $uri $uri/ /index.php?$query_string;
        }

I have excluded the if($prerender = 0) {...

Now I just do the try_files after the first if

if ($prerender = 1) {
            
            #setting prerender as a variable forces DNS resolution since nginx caches IPs and doesnt play well with load balancing
            set $prerender "service.prerender.io";
            rewrite .* /$scheme://$host$request_uri? break;
            proxy_pass http://$prerender;
        }
        
        try_files $uri $uri/ /index.php?$query_string;

Is this fine?

thiagoferreiraw · 2021-11-18T12:32:47Z

For those struggling with the nginx configuration on SPAs (react, angular, vue.js), here's an overview on how it should work:

How the @prerender location works 🥇 :

Given we have a default location (/) with "try_files $uri @prerender", here's what happens:
First, nginx will try to find a real file on the directory, such as images, js or css files.
  If there is a match, nginx will return that file.
If no real file is found, nginx will try the @prerender location:
  If the user agent is a bot (google, twitter, etc), set a variable $prerender to 1
  If the user agent is prerender itself, set it to 0 back again
  If the uri is for a file such as js, css, imgs, set it to 0 again
  Now, if after all of these conditions we have $prerender==1, we will;
      Proxy pass the request to prerender and return the cached html file
  If we have prerender=0:
      Default to our own index.html.
      Since this is a SPA, all uris that are not a real file will be redirected to index.html

Caveats 🚨

The if directive in nginx can be tricky (please read https://www.nginx.com/resources/wiki/start/topics/depth/ifisevil/)
In summary, we should never use try_files and ifs in the same location block.
This is the reason why we have to use rewrite on the @location block instead of try_files.

Final nginx conf with SSL 🔒

It's very similar to the first example, I just needed to add a root path in each location:

# MANAGED BY PUPPET
server {
  listen       *:443 ssl;


  server_name  example.com;

  ssl_certificate           /etc/nginx/ssl/example.crt;
  ssl_certificate_key       /etc/nginx/ssl/example.key;

  access_log            /var/log/nginx/example.log combined_cloudflare;
  error_log             /var/log/nginx/ssl-example.error.log;
      add_header "X-Clacks-Overhead" "GNU Terry Pratchett";


  location / {
    root      /usr/local/example/webapp-build;
    try_files $uri @prerender;
    add_header Cache-Control "no-cache";
  }
  # How the @prerender location works:

  location @prerender {

        set $prerender "service.prerender.io";
        rewrite .* /$scheme://$host$request_uri? break;
        proxy_pass http://$prerender;
        break;
    }

    rewrite .* /index.html break;
  }
}

If you are using puppet to manage your infrastructure... 🤖

I preferred creating a template file with the @prerender location for readability. Additionally, this config should only be done in production, so I added some conditionals as well:

  if $environment == 'production' {
    # prerender.io is a SEO tool used to process javascript websites into a robot-friendly page.
    # Please read the details on profile/webapp/prerender_nginx.erb
    $nginx_try_files = ['$uri', '@prerender']  # the $uri must be single quoted!
    $nginx_raw_append = template('profile/webapp/prerender_nginx.erb')  # Only the @prerender location goes in this block
  } else {
    $nginx_try_files = ['$uri', '/index.html']  # the $uri must be single quoted!
    $nginx_raw_append = []
  }

nginx::resource::server { $name:
    ensure                => present,

    listen_port           => 443,
    ssl_port              => 443,

Hi everyone!
there is an updated, official set of nginx configuration files here:
https://github.com/prerender/prerender-nginx
