Seeing all the hype around Bolt.new, I decided to give it a try, and within just 30 minutes, I built a fully functional web app for screen sharing.

How It Works:

- One user opens a room and receives a unique code.

- Participants join by simply entering the code to view the shared screen.

After that initial build, I moved the project to Cursor to continue iterating and enhancing its features.

Github: https://github.com/tonghohin/screen-sharing

Demo: https://share-your-screen.vercel.app

Did a quick test on Demo site. It works like a charm.

One issue: when I stopped sharing, my audience (my another computer) can still see my shared screen (I assume the last frame), what I think it shouldn't. And there is no indication or whatsoever that I have stopped sharing.

What I love about developing with cursor et al is it forces devs to keep the app simple.

No custom UI bloat when shadcn will do; no feature creep when the outline is fulfilled.

Simple apps < 30,000 LOC means cursor can keep the code base in the context window, so its generations stay high quality.

Tried making one that would work on almost any device:

Runs on Hetzner EU currently.

Maybe I should open source it.

Great! Thanks.

While we're on the subject of WebRTC, if anyone would need MIDI over WebRTC, here is my take on it:

Slightly off-topic, but I’ve been searching for a long time for something like this, but for text chat: go to a website; create a room; share a code/link with others; people join and chat; then at some point in the future the room simply disappears (you can save a log if you want). Ideally anonymous with the best possible cryptographic implementation.

Has anyone stumbled upon something similar? I hate having to register and login to every chat platform, especially bloated ones like Discord and Slack. The closest one to what I want is gitter but it requires a GitHub signin.

If you can get remote control to work that would be amazing. I assume that's impossible with current browser APIs though. A real pain point of Google Meet.

Gave it a quick run! Works great. The notification to share your screen goes away quickly. Is there any way to get back to it? I generated a new code to fire the notification again.

Nice work.

Does this share your screen across domains? If so, how?

Doesn't work on Linux?

I'm not sure, but is it possible to make it work on Android? I've tried on my pixel 7a, it gave me the code, I pasted it in another device in Safari, but it was only Loading... on the button.

Immediately upon loading the homepage:

> Application error: a client-side exception has occurred (see the browser console for more information).

why the source have an accordion and carousel component? :)

Awesome demo! Are you paying for the TURN server?
