Reactive Data Without the Async Headaches

Modern frontend development often turns into a battle with async code: async/await subscriptions dependency arrays memoization race conditions unnecessary recomputations What if you could simply describe your data and let the system handle the rest? That's exactly the idea behind rs-x . To demonstrate it, I built a small demo that tracks the real-time position of the International Space Station (ISS) . 👉 Live demo: https://robert-sanders-software-ontwikkeling.github.io/rs-x/demo The Idea The demo polls a public ISS API and exposes the data as part of a reactive model. ⚠️ Note > If many people open the demo simultaneously, the public ISS API may return Too Many Requests errors due to rate limits. It returns: timestamp latitude longitude altitude velocity At the same time the model contains an expensive computation to demonstrate how rs-x handles dependencies. The key idea: Only recompute what actually depends on changed data. The Demo The API is polled every few seconds using RxJS. cons
