Lottie for Android, iOS, and React Native VS Rx.NET

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.

DynamicData is a .NET library that brings the power of reactive programming to collections. It is built upon the principles of Reactive Extensions (Rx), extending these concepts to handle collections like lists and observables more efficiently and flexibly. DynamicData provides a set of tools and extensions that enable developers to manage collections reactively, meaning any changes in the data are automatically and efficiently propagated through the application.

One of the greatest things i discovered recently, is Reactive programming / Reactive Extensions ( https://github.com/dotnet/reactive ).

https://github.com/dotnet/reactive has a lot of different time related extensions for "events". Maybe you'll find something for yourself, if you google for rate limiting with reactive.

Another option is to use the RxJava library in Java. This library uses reactive programming principles to make it easy to write asynchronous and event-driven code. It's particularly well-suited for handling streams of data and allows you to write code that is both efficient and easy to read.

I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.

If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.
