snapdroid VS Lottie for Android, iOS, and React Native

It's all done with Mopidy + Snapcast. Mopidy has various frontends, but the Iris web frontend supports Snapcast and can be controlled from any web-capable device; it can be used to assign/change device groups, assign certain streams to certain groups (you can have multiple sources playing on multiple devices/groups and control them from there), etc. I also used the Snapdroid app, which will allow you to adjust things like latency, individual device volumes and stream volumes, etc on your phone or tablet. Beyond that, you can integrate Home Assistant and pretty much get it to act however you want, including being fully controlled via voice on both Google and Amazon (and ultimately Cortana, ick) platforms. Of course that takes some setting up that some wouldn't consider "easy", so YMMV.

* Server running mopidy [1] with all your audio loaded up on it and connected to Spotify.

* Install the Iris plugin for UI [2] on server

* Install snapcast [3] server on the audio server and snapcast client on raspberry pi's near all stereos you want to pipe audio into

* Put bookmarks to the Iris page on all family member's phone home screens.

* Add the snapdroid app [4] to each phone so people can adjust volume of each stereo and also play audio on their phone (or anything it's bluetoothed into)

The Snapdroid app for Android is pretty basic. AFAIK there still isn't a UI for iOS.

Worth mentioning that After Effects can export CSS/SVG/canvas animations with the free bodymovin/Lottie plugin. This is my personal go to for creating web key frame animations and elements.

Not every after effects feature is exportable, but it’s the best and most reliable solution I’ve found for this type of workflow, maybe due in part though to my previous experience with AE.

A smooth and visually appealing on-boarding experience can greatly impact how users perceive the quality of your app. In my previous article, we explored how to create custom splash screens on Fire TV apps to optimize the startup time and improve user experience. Building on that knowledge we will take a step further and learn how to develop an animated splash screen using Lottie for Fire TV applications.

I'd suggest Lottie with a JSON animation file

Lottie[1], an Adobe After Effects plugin, fills a gap in vector animation authoring and is quite widely used (primarily in mobile applications but also works on the web, Discord for example supports them for stickers).

It's a pity SVG animation authoring tools never eventuated since it's an underutilized native format.

Unity can export to WebGL/WASM, so that's one option if you're making some kind of heavy interactive experience and you don't mind waiting for it to load. For just animations there are tools like Lottie that can help. I think things are generally a lot more fragmented than they were in the Flash/Shockwave days though.
