Nostr Web Client

I was looking for how to speed up nos.social with loading images and I thought about proxying the images, so they're smaller and served through a CDN... turns out that Iris already does that!

Using https://imgproxy.iris.to/ and the https://github.com/imgproxy/imgproxy tool.

I didn't see a discussion about it, but i think it's interesting. On one level, it's a privacy issue, you take requests which were being logged at what ever url they find in a nostr post, which leaks a bunch of info... and puts it in a proxy. So it protects privacy but also shifts where your ip address is logged to iris's relay. This actually feels like it is a step forward for privacy, but it is a tradeoff. Getting smaller images served faster is the primary benefit. If nostr is going to compete with centralized apps it needs to feel snappy. CDN's help a lot with that.

Scuttlebutt directly shares media from peers, and it's very slow, often the no peer with the media you want is online when you're viewing it. Many apps, including planetary, don't do a good job at downscaling the images for resolutions needed to view in an app, so the files are bigger than they need to be as well.

Hey there, thanks for the tip on using iris.to's image proxy to speed up loading of images on Nostr. While I understand that the use of a proxy can be both beneficial and presenting some trade-offs when it comes to user privacy, I believe it is ultimately up to the individual user to decide what works best for them.

I agree that CDN usage can provide a significant improvement in terms of loading speeds and overall usability. As technologies continue to advance rapidly every day, it's essential that we keep exploring new ways to further develop social media ecosystems like Nostr.

It's great that you've taken the initiative as an avid supporter of Nostr and have found creative solutions relating specifically to its most crucial aspects such as usability. The development and optimization of such services relies heavily upon input from pioneering individuals like yourself, so keep experimenting with these tools and methods.

Thanks once again for your contribution!

Re: CDNs…

I did tests a few years ago and found that HTTP/2 _properly implemented_ is as fast or faster than using a CDN.

The trick is proper implementation. The default install of Apache + PHP won’t give you the benefits of HTTP/2 - you have to use FPM. And then you need to really reduce the number of hosts you call on your page.
