Spring Cloud Gateway and NGINX - nginx

Do I still need NGINX to serve static content like JS etc and reverse proxy request to backend, or it can be done with just Spring Cloud Gateway?
Spring docs has a following image:
And I found no description there on how to return static content to the client, does it mean it's considered bad practice and I need extra step of reverse proxying adding its latency?
If not, where can I find more info on how to do that with Spring Cloud Gateway, especially if I'm going to make oauth2 authorization-code flow authentication using Spring Gateway?

I am using NGINX as reverse proxy, but i thought about the same question and i tried (same thing for me. oauth2 authorization-code flow authentication). So, you can serve static content with just Spring Cloud Gateway, it is possible.
For example if you are using React, take build and copy all build files to under resources/static/frontend-name location. Then, disable (permitAll) web security in that all frontend locations. So you can access just typing http://gatewayserver/frontend-name/index.html
However, I don't think to use it in production environment, NGINX still sounds like better idea for me. Because when I take release for frontends, why do i need to take release for gateway at the same time or vice-versa? But, if you have small project, it might be an option.

Cloud Run mapping services by URL path (using custom domain and wildcards)

I've been trying to migrate my solution from Google Cloud App Engine to Google Cloud Run and have been struggling a lot.
I have 3 services in app engine for each staging environment, let's call them api, front1, front2. front1 has custom domain name assigned www.example.com, as well as staging subdomain www.dev.example.com. Using dispatch.yaml rules I route requests to appropriate services, for example: requests containing api/* are routed to api service, default path routes to front1, /foo* routes to front2. Everything is working there perfectly well, however, hosting the solution on Cloud Run would decrease the costs a lot.
So at the moment, I am really struggling to understand how could I fully replicate this behavior in Cloud Run. I've tried following firebase routing, but it requires to host an app on Firebase as well and doesn't route all traffic for route /api/** to my api service.
I've tried following this article, but I cannot select my service since I selected Internet Network Ednpoint Group option for backend type, which only can point to a single url. Also, I am not sure if it will support wildcard routing there.
I'd highly appreciate any help here, I am totally out of options at the moment.

Can NGINX be used to route traffic to a Firebase project?

It's unclear for me and I haven't attempted yet, but would like to know if I can have a NGINX server routing traffic to a Firebase instance. I can't find relevant articles on internet and neither here so, maybe some fo you already tried this.
Background:
Our React app is running on Firebase already. But, we also have a landing page/website which is backed by Webflow.io to allow quicker edits with less developer frustration. They are also running on separate domains.
We already have an instance of NGINX(inside a docker container) as part of our API gateway so, would be good to use the same instance.
Result:
What we are looking to achieve, is to put both React app and landing page on the same domain. Then, use NGINX to route to required instance wether the user is logged-in or not. Anyone attempted something like this? If not this doesn't work, I'm open to general ideas on how to make it better from your experience.
You can totally do this, for example if you're using OAuth you can perform a token introspection from nginx whose result will determine the route to use, take a look at this https://www.nginx.com/blog/validating-oauth-2-0-access-tokens-nginx/
Alternatively you can use something similar to the google IAP that is probabely more easy to secure for production, i know that ory/oauthkeeper is easy to use, open source and hightly customizable.

Firebase - custom url - avoid *.firebaseio.com

I use firebase with custom url. However the websocket connection uses still wss://.firebaseio.com/.
Is it possible to move this configuration to the custom domain?
also 'verifyToken' and getAccountInfo is always through https://www.googleapis.com/.
thank you
No - unfortunately that's not possible. What you're asking would involve rewriting some of the internal logic hard-coded on Firebase's servers... and Firebase doesn't expose that kind of functionality.
While this may be possible, it's not a recommended solution. You won't be able to achieve this purely by configuration alone, and it is just speculation about whether or not it will work.
When Firebase initializes, there is a configuration parameter for the destination of the websocket it establishes. Since you haven't said which platform you're using, I'll leave it up to you to read the documentation to see which parameter you have to change in your call to initialize Firebase.
After you change this parameter, you will need to have some proxy service at the destination to route all that traffic to the actual websocket destination at Google. This is a broad topic, and you will have to figure out how you want to implement this proxy.

Push Notification for Http Websites

I have implemented web push using Firebase using Service-workers (which works only for https website). I want to use web push notification for http website.
I have read that it is possible to implement the web push for http website using some tweaks like subscribing to any third party.
Two questions I want to ask:
a) Is it possible to achieve the same without using any third party library?
b) How can I achieve the same behaviour for my website?
Any help is appreciated.
a) Is it possible to achieve the same without using any third party library?
From the developer guide: No, During development you'll be able to use service worker through localhost. but to deploy it you need HTTPS, the site registering the service worker must on on HTTPS and the service worker, which has to be on the same origin, will be served over HTTPS as a result. For security reasons. Having modified network requests, wide open to man in the middle attacks would be really bad
b) if you need web push notifications and you don't have an SSL take a look at Pushpad Express https://pushpad.xyz/

Is it possible to route to a PROJECT_ID.appspot.com url using gRPC endpoints on GCP?

I'm trying to quickly setup a gRCP-endpoint instance on GCP but they seem to be only accessible from inside GCP.
The thing is you can have an endpoint that is managed and it will have a PROJECT_ID.appspot.com URL.
Also, can a gRPC endpoint be publicly accessible ? Is it recommended ?
pRPC is one solution, as I am using golang.
Following this post I might use it. It allows to do gRPC on appengine, without the streaming capabilities, which is fine for me now.
Hope someone has a better answer.
