@Black Caiman found a solution? Haven't seen your clarification yet

Hello, I updated the question in stackoverflow

the bucket is not accessible in public so I think that's why I am having cors error

should I use aws-sdk for this?

I don't have permission to make the bucket public and boss wants it to be private

you need to generated a presigned url

you send a request to your backend which then uses aws-sdk to speak with s3 and generate the url

then you return this url to the browser

and then open the url to get the file

linesofcode mentioned a good way to handle private files. Another and more costs effective way would be to ask a cdn for this signed url. Only the cdn have access and verify the identity to the files. The cdn caches the files and edge them @Black Caiman

ohh didn't see your reply @linesofcode 😅

keep in mid the cache... s3 caches 1 hours. cloudfront (aws cdn) saves 24 hours. so you pay ~24 times less ^^

wait there's payment for every generated presigned-url? 😅

just new about this please have mercy hahahahaha

you pay for the get

it's also different in subscription? or is it also in the package?

no its default s3 costs

ohh got ittt

u sure?

not really hahahaha

hahahahaahah. What specifically is missing?

this one it's confusing hahahaha

I am totally noob about aws 😅

and it's a huge costs thing.. imagine paying 100.000 $ only for S3 stuff and the you switch to S3 with CDN (Cloudfont) and only paying ~4.200 $...

well yea, that's nice

so: of course you can archive the behavior your want, but for what price?
100.000 $ or ~4.200 $
🙂

It depends on your scale…..

of course it does, but % doesnt change

absolute values changes, bot not percent

I haven’t paid over a dollar for s3 yet

ohh i thought thats comma hahaha so s3 with cdn is cheaper than s3 only?

it's a combination of both. And because the cdn caches everything it costs 24 times less, because cdn cache is 24 hours and s3 only 1 hour

ohh okay gotta tell boss right away hahaha

thankyouusomuchh!! ✨

ohh this is not gonna be the last coz I'll have a lot of questions soon hahahaha

but is this how to generate presigned-url?
https://awstip.com/generating-a-presigned-url-for-aws-s3-using-node-js-and-aws-sdk-v3-56eee5d2db8e

it is, yea, but it's also without cloudfront

ohh I see gotta do some research in google and youtube university hahahha

yes, you want to go the yellow path and I recommend you the path with the green arrows 🙂

I think I kinda get it now

But I'll do my own research tomorrow also. Gotta go sleep now

Thanks again!!! @B33fb0n3 😊

also @linesofcode

yea, you will find the right way for your specific use case 👍

no problem

Hello! How are you guys doing? @B33fb0n3 @linesofcode

Got a question 😅

what does this mean?

@Black Caiman hey! Let's take a look at that. To focus only on the relevant path, would you open a new thread, with a description, what you now done? You can ping me, I will answer 🙂

got ittt
