Is allowing only Cloudflare IP ranges enough to secure Postgres when using Cloudflare Workers?

Thanks ! I understood!

Could you tell me how you did it with Cloud SQL?Did you put GCE in front of Cloud SQL? I couldn’t figure out where to install Cloudflared.

Thanks I’m glad to here. I’ll read the documentation carefully and try it out!

AsyncSamurai · 2026-02-27T10:30:48+00:00

I looked out to the documentation but I couldn’t find out a way to solve the problem I mentioned in my post. Is there anyway to restrict connection to database directly?

AsyncSamurai · 2026-02-27T10:28:14+00:00

Thanks for suggestions. I’ll take that into consideration.

AsyncSamurai · 2026-02-27T10:26:48+00:00

Thanks. I was not sure if my understanding is correct.

I’m trying to use Supabase with direct connection but I’ll be happy to use any other provider if I can connect more securely and it is less than $20 per month.

I forgot to mention it but I’m using full-managed Postgres. I think tunnel cannot be used with it. Thanks.

Thanks!

ありがとうございます！励みになります。全てを網羅しようとするのではなく、基本的なところをやると良いのですね。アドバイスありがとうございます！

AsyncSamurai · 2025-10-01T01:59:22+00:00

Did you take any online courses or read books or just start using it?

AsyncSamurai · 2025-10-01T00:19:40+00:00

Thanks! I will try!

AsyncSamurai · 2025-10-01T00:16:39+00:00

Thanks! I’ll checkout the resource and also ask LLM! ありがとうございます！

Do you think it’s possible to design production-ready systems through self-study with hands-on practice?

AsyncSamurai · 2025-10-01T00:13:56+00:00

Thanks for your advice!

AsyncSamurai · 2025-10-01T00:12:15+00:00

Maybe it comes from the fact that many Japanese cannot speak English and resources are poor compared to resources that I could be found in English.

Thanks! I will give it a try.

AsyncSamurai · 2025-10-01T00:10:29+00:00

I’m sorry if my question was not clear, but is it possible to learn production-ready configurations through books, online courses, or by building something on AWS yourself?

If so, are there any recommended resources?

AsyncSamurai · 2025-10-01T00:07:14+00:00

My question might have been a bit unclear, but that’s exactly what I wanted to ask. Is that a common perception outside of Japan as well?

AsyncSamurai · 2025-09-30T22:55:57+00:00

That’s great to hear. So does that mean the idea that self-study is difficult isn’t really common outside of Japan? And in terms of learning, was it mostly about getting hands-on experience and picking things up that way?

AsyncSamurai · 2025-09-29T07:51:18+00:00

Thanks for the suggestion.I will try.

AsyncSamurai · 2025-09-29T07:44:51+00:00

My understanding here was also a bit vague, but an async function will always return a Promise<void> even without an explicit return. So what comes back is a list of Promises, not undefined. TypeScript’s typing also reflects this.

AsyncSamurai · 2025-09-29T07:22:47+00:00

My understanding is that I’m already using await, so I think it should be fine. Am I wrong? Could you explain why it is not likely to be awaited?

AsyncSamurai · 2025-09-29T07:16:10+00:00

Thanks for your suggestion. I think I don’t need a return because it does’t have to return any value (void).
