Modern web applications are increasingly complex, often burdened by heavy JavaScript loads that demand significant CPU resources, which can compromise user experience, especially on low-end mobile devices. The main thread, primarily responsible for UI tasks, becomes overloaded when tasked with non-UI responsibilities like data manipulation, leading to sluggishness and performance issues. Web workers provide a solution by allowing JavaScript to run in the background, freeing the main thread and improving responsiveness. Despite their potential, web workers are underutilized due to the complexity of managing communication via the postMessage API. Comlink simplifies this by transforming the message-based API into a more intuitive remote procedure call (RPC) system, allowing developers to interact with functions in workers as if they were local, thus enhancing the development process and user experience. While Comlink also supports service workers, WebRTC, and WebSockets, its primary role is to help developers offload non-UI tasks from the main thread, ensuring smoother operation of web apps across various devices and network conditions.
