Question: Integrate with Prerender Service (`prerender-node`) about functions-samples HOT 3 CLOSED

Yes :) Here is a sample that uses an express middleware: https://github.com/firebase/functions-samples/blob/master/authorized-https-endpoint/functions/index.js

from functions-samples.

Oh and sorry, I meant that you can use express middlware with Cloud Functions. Not sure about pretender-node since I'm not very familiar with it but if it supports simply calling a function with an HTTP request and HTTP response (like Express) it should work.

First of all, sorry for my poor English.

After searching through Deep Web (joking), I found the solution. And the coolest solution was that I was able to integrate my Pioneer Ionic application with Firebase Hosting using Cloud Functions.

After reading the following topic:

firebase/firebase-tools#33

The @TheRoccoB user explains how to host the static Web application in Firebase Hosting and redirect traffic from a URL to Cloud Functions.

What I did was map the routes that I have to index as:

{
        "source": "/ shop / **",
        "function": "ssr"
      },
      {
        "source": "/ * / promotions / **",
        "function": "ssr"
      }

Since "ssr" is the name of my function in Cloud Functions. So I used the library https://github.com/prerender/prerender-node to check if the request is from a google crowler, in case I redirect the request to a https://github.com/prerender/prerender server.

const prerender = express ();
prerender.use (cors);
prerender.use (
    require ('prerender-node')
    // .set ('prerenderServiceUrl', 'http: // localhost: 3000')
    .set ('prerenderToken', '** TOKEN **')
);
prerender.use (require ('prerender-node'). set ('beforeRender', function (req, done) {
    // do you need to do?
    console.log ('Rendering URL:', req.path);
done ();
}));
prerender.use (require ('prerender-node') set ('afterRender', function (err, req, prerender_res) {
    // do you need to do?
    console.log (req.path + 'rendering completed!');
    console.log ('Errors:', err);
}));
prerender.get ('*', (req, res) => {
    console.log ('Calling function for URL:', req.path);
    res.set ('Cache-Control', 'public, max-age = 300, s-maxage = 600');
    res.status (200) .send (fs.readFileSync ('./ www / index.html'). toString ());
});
exports.ssr = functions.https.onRequest (prerender);
