In React Native, the javascript thread and the native UI thread communicate over a JSON-serialized bridge. This bridge is a bottleneck. If you attempt to send 60fps real-time sensor metrics over the bridge to render a chart, you choke communications, dropping frames and freezing the UI.
We faced this while building our site inspector app. Telemetry feeds from construction sensors caused the app to crash due to garbage collection storms on the bridge thread.
We solved this by adopting React Native Reanimated and Skia. By executing calculations directly on the UI thread using worklets and avoiding JS-to-Native bridge roundtrips for chart draws, frame rates stabilized at a solid 60fps. Keep heavy animation data off the bridge.
From a systems perspective, implementing this solution required auditing our telemetry structures. We mapped key transactions across our distributed database queries and evaluated the locking overheads under heavy load. By setting up strict validation rules in Prisma, we isolated runtime query errors before they could trickle up to the client view.
Ultimately, building durable systems means choosing boring abstractions and documenting architectural decisions (ADRs) meticulously. When infrastructure behaves predictably, your team can deploy with high confidence. We enforce these performance and security budgets in our continuous integration (CI) workflows, ensuring that every merge maintains the same standard.
