In a recent presentation, Alex, a principal engineer at Amazon, discussed the challenges of developing a user interface for living room devices such as streaming sticks and gaming consoles. These devices vary significantly in performance capabilities, making it essential to create a unified application for Prime Video. The architectural shift from a dual tech stack (React and JavaScript) to a Rust and WebAssembly foundation aims to enhance performance and optimize user experience across all devices. Alex also shared insights into lessons learned throughout this transition.
Living room devices present unique challenges due to diverse performance capabilities, requiring a unified approach to develop a Prime Video UI that works across all types.
The architecture overhaul transitioned from a dual tech stack of React and JavaScript to a new Rust and WebAssembly foundation, enhancing performance and user experience.
