Great video. Nice to see you come back to GO. It’s very efficient for such backend work.

[@yassinesafraoui]

It's important to note that you have to make sure ressources have unique ids because there is no way to invalidate cloudflare cache afaik

[@xoutaku7600]

set your proxy so it only only accepts requests through the cloudflare cdn , either directly in the proxy code or through the server firewall if the cdn has a static dns entry you can take advantage of

[@WebDevCody]

I could probably just setup a firewall on the docker image itself

[@beemkhan]

I've watched a lot of your content, this is exactly what i expect a good engineer to share, youve looked at tech with your own initiative and shared the knowledge with everyone. Very much appreciated. Thank you

[@alessioragonesi8549]

To avoid ddos on the go proxy you can block direct ip access over http to your server. I remember it being an option for a wordpress website with cloudflare so there has to be a way to do it outsided of wordpress too.

[@WebDevCody]

@@alessioragonesi8549 I think I could only allow cloudflare ip address as well

[@joeyywill1234]

so what is the go proxy actually doing?

[@WebDevCody]

I’m not sure

[@ali2kan]

from my understanding from the video, wasn't he using the proxy to route client requests to the db?

[@sama7496]

same here i didn't get it too

[@the-engineer-r4j]

The proxy is just being used as a way to request files from the DB without having direct frontend => DB requests

Are you using the UI with a docker image? In my experience, if you dockerize your next app, it brings down the memory usage to somewhere around 80-120MBs atleast in my case, thought it would be usefull

Yes I am

[@Steel0079]

Hi, why didn't you use something like nginx? Is it because you are using convex?

[@WebDevCody]

I need to hit an endpoint to convert an id. I don’t think nginx can run logic? I can also potentially add auth checks in the proxy if I want

[@abhishekmehandiratta4241]

Why not just have cloudflare cdn in front of convex static asset urls?

[@WebDevCody]

because I wasn't sure if someone would be able to figure out my convex project id via websocket events and then by pass cloudflare directly to hit my convex.cloud url directly. that did cross my mind, convex has the ability to setup custom domains, so technically I could just point cloudflare to convex via a domain, I just went with this approach first and didn't think too hard about it.

[@y.m.o6171]

Hi Cody. I think you could do better by not reading all the file content in one shot. I see that you are using ReadAll. There are maybe better ways to stream that with i think a tee in go. cant remember what is called but it allows you to tie one buffer and reader and let the magic happen. I will look it up and see if i can find it

[@y.m.o6171]

kzbin.info/www/bejne/bquZoJ55nMmFe9E this is a great talk about many details in how to build a proxy in go. so io.Copy should do what you want. if you need to do more processing `io.TeeReader` will do what you want if you need more complicated logic

[@raideez]

So next.js wasn't just able to handle ur requests without consuming lots of bandwidth? So you added go backend to do the video requesting? For heavy loads its always recommended to have seperate backend.

[@WebDevCody]

I'm not too sure what was going on. There was two things I needed to debug. Was it the tunnel causing issues, was it next.js, or was it my javascript implementation. Overall I decided to instead just use a simple go proxy since I knew it would use little memory and run fast.

[@CarlosDuque-e3j]

Hi Cody, I was wondering why do you need the proxy. Is it because you can't send a request directly from cloudflare to convex? Also, pretty cool video. I really like seeing this kind of system design videos that are not only explain the parts of the system but rather contextualize in a real project how they work.

[@WebDevCody]

I think the issue is that if someone knows my convex project id, they could potentially hit my convex http endpoint directly to download files and bypass cloudflare which would mean a larger bandwidth charge. I wasn’t sure if that project id was exposed anywhere in when someone loads up the convex client and starts sending web socket events. Basically I abstracted convex away from the user entirely in regards to files to keep all that hidden. Nothing can download files from convex except my go proxy. Maybe it’s over engineering, but I don’t want a silly ddos from a yt hater to run up my bill.

[@CarlosDuque-e3j]

​@@WebDevCody That makes sense, thanks for explaning that. It's sad you gotta worry about that stuff because of haters but I guess it makes you think more about security, which makes your project more "professional" if you will.

[@crustydev5561]

Doesn’t cloudflare frown on using the cdn for videos?

[@WebDevCody]

I can’t find where they say that

[@jimbin93]

@@WebDevCody They emphasize multiple times that you shouldn’t serve most of your video cache. Content like HTML, JS, and CSS is acceptable, but for videos, they recommend using Cloudflare Streaming. You can find more information in Cloudflare's Terms of Service and forums. That’s my two cents!

[@Oldbettie]

Actually was load testing railway the other day it seems to not like sending images or videos from next apps i was getting horrid performance. This seems like a decent solution

[@WebDevCody]

@@Oldbettie yeah idk why, something is fishy about it. Were you using a tunnel?

[@pedrofrazaopacheco]

Hey Cody I am not 100% sure about this but a while ago I saw an article that you can’t cache user generated assets on cloud flare and you need to use their service R2. I don’t know if this applies in your case but just to let you know that it can be against their terms of service

[@WebDevCody]

I'd be curious if you can find that article. Claude AI is saying caching dynamic or user generated content is allowed as along is it isn't illegal or copy written assets. The article needs to link directly to the cloudflare terms of service or else it's just hearsay imo, but it's always good to double check these things.

[@pedrofrazaopacheco]

@@WebDevCodyok i think my comment was deleted because i added a link but basically this is from their website Unless you are an Enterprise customer, Cloudflare offers specific Paid Services (e.g., the Developer Platform, Images, and Stream) that you must use in order to serve video and other large files via the CDN

[@nchomey]

It's in their terms of service. Html only in the cache, unless you use a paid service (like r2). Yet, html isn't cached by default and scripts (and I think images) are...
