Efficient Real-Time Flight Tracking in Browsers: Framework-Free, Cross-Platform Solution

Introduction: The Challenge of Framework-Free Development Building a real-time flight tracker that renders 10,000+ live aircraft on a 3D globe in the browser is no small feat. The conventional path? Lean on frameworks like React for UI, Three.js for 3D rendering, and let them abstract away the complexity. But what if you strip away these crutches? What if you build it framework-free, using Rust, WebAssembly (WASM), and raw WebGL? That’s exactly what I did, and the result is a high-performance, cross-platform application that loads in under a second and works seamlessly as a PWA on mobile. Here’s the kicker: it’s not just about avoiding frameworks—it’s about why avoiding them unlocks superior performance, customization, and control. The core challenge lies in the trade-off between abstraction and efficiency. Frameworks like Three.js simplify WebGL by abstracting away its low-level details, but this abstraction comes at a cost. For instance, Three.js’s scene graph and rendering pipeline
