Firebase Integration Guide

This guide will guide you on integrating Prerender with your Firebase Hosting project using Cloudflare as a proxy on the domain and then implementing a Cloudflare worker.

Video guide:

 

 

Prerender Token Location:

The location of the Prerender token has changed. You can find it under the Security and Access menu under Prerender Token.

 

You can find the integration's source code on this link.

Text guide:

  1. Begin by integrating Cloudflare with your domain. 

    This requires you to go to your domain registrar's DNS settings, remove the existing name servers, and replace them with the ones provided by Cloudflare.
    Access the DNS menu in Cloudflare to find the necessary name servers.
    Cloudflare_DNS

  2. Update DNS Records in Cloudflare

    Save your changes in Cloudflare, then add the DNS records we get from Firebase.
    Navigate to Firebase, select your project, and add your domain as a custom under Build -> Hosting menu point. Add the A and TXT records provided by Firebase to Cloudflare, ensuring the proxy status is enabled for the A record.

  3. Verify Domain with Firebase

    After adding the DNS records, use Firebase's "Verify" option to confirm the setup. The DNS update process may take a few minutes, so feel free to proceed with the next steps. 

  4. Configure Additional Domains

    If you have a www version of your domain, then add that also to Firebase,  and add a corresponding CNAME record provided by the Firebase dashboard in Cloudflare for www, ensuring the proxy status is enabled, and then save your changes.

  5. Deploy Cloudflare Worker for Prerender

    Click on Workers & Pages

  6. Create a new worker

    • Open your Cloudflare Dashboard and click on Compute(Workers) and select  Workers & Pages on the left side
      Cloudflare_int tep 1

    • Then click on Create on the Worker Overview page.
      Cloudflare integration step 2

    • Then click on the "Create Worker" button.
      creat  worker CLoudflare

    • Give your worker a descriptive name. e.g.: prerender-worker
      name worker CF

    • Click on the Deploy button at the bottom right to initialize the worker.  
      deploy CF Worker

 

7. Add the Prerender worker's code

 

8. Configure the worker

    • Step back to the previous interface by clicking on your worker's name on the top left. 0aa1cdd6-b87c-4a26-b797-5b8cf5c1f9fe

 

    • Go to Settings and add the zone and routes for your site. 
      add routes to worker

    • Click on +Add at Domains & Routes
      add route2
    • Select route
      add route3

 

    • Add a Route pattern that matches your site and select the Zone where your site is located.
      Examples of the Route setting: 
Website Address Type Route Pattern
example.com example.com/*
www.example.com www.example.com/*
Both with/without www *example.com/*
Any subdomain *.example.com/*
Specific subdomain blog.example.com/*
Multiple subdomains (sub1|sub2).example.com/*

 

    • You can add a route specific to your subdomain. If you want to test Prerender on just one of your domains or subdomains, you can add another route to the worker later.
      sav route

 

    • Select Failure more:

    • Click on Add Route to save the setting.

9. Add the Prerender token as an Environment Variable.

    • Next to Variables and Secrets, click on +Add

    • Add a text variable named "PRERENDER_TOKEN" and set its value to the token from your dashboard. Then, click Deploy.

It might take a couple of minutes for the integration to start working after the final deployment.

 

 

Verify Your Installation

After integration, it’s important to verify that everything is working as expected. We’ve provided an easy-to-follow guide to help you test your setup and confirm that Prerender is functioning properly.

 

Is the Prerender integration working on other pages?

Test if the Prerender integration works on the other pages based on this guide: Verify the integration

If you don't see the Prerender headers / IDs, then the Integration is not working, which might be why the other URL is not cached
