LiveSlides - Present a slide deck with live links
Hey gang, just want to share LiveSlides, a small side project I’ve been working on this month.
LiveSlides is a web app that lets you create slide decks in Markdown and present them to the audience in their own browser. You start the presentation, share a link, and then as you’re presenting, changing the slide will also update the view in each audience members’ browser. And, when the presentation is finished, they’ll get controls for themselves to review your slides as much as they want.
It uses Phoenix, LiveView, and some OTP.
If you want to learn more, I wrote up a post here outlining how it works and how I went about it.

Not implemented (yet…) but I did have this idea as well. The idea being that, as an audience member, you can “detatch”, and go into solo viewer mode and have full control for all the slides that have been shown up until that point, and possibly see some indicator that the presenter has moved on, etc, and then hit one button to “re-attach”. Like what happens when you’re watching something that’s being DVRd (e.g. YoutubeTV) - you can pause, rewind, but you can’t see into the future.
The functionality won’t be too hard, just making sure we expand what’s being broadcast on slide changes so that each LiveView knows enough to set up its own state to match that of the presentation’s GenServer.
Awesome to hear you had/have the same ideas, great minds think alike!

Really cool. I’ve had this idea for ages, but never executed 
One feature I thought of, and I think it’s not there, it to allow viewers to freely go back to any slide that was already shown, with a button appearing “go back to current slide”. But at the same time they cannot go forward and ruin all the surprises.

Great work! Would be nice to have the blog post be presented by LiveSlides

Funny you mention that, I did have the idea of writing up a little module that would just perpetually update the slides for a presentation so I could share the public link and anyone could get see the experience.
You CAN check out this demo presentation I had created, which is actually most of the same content as the blog post.
