The article discusses the problem of organizing effective component interaction in client web applications based on component architectures. It is shown that as the scale of interface systems increases, traditio­ nal approaches to data exchange between components lead to redundant calculations, more complicated support, and lower performance. Using the example of frameworks, the existing mechanisms for synchronizing the state and updating the user interface are analyzed, their limitations related to global change tracking and the lack of builtin support for two-way data transfer between components are identified. A Bidirectional Component Linking Model (BCLM) is proposed, based on the direct exchange of relevant state changes between logically connected components. A synchronization mechanism has been formalized through the display of publication and application of data, providing adaptive interface updates without the involvement of centralized repositories. It is shown that the proposed approach makes it possible to reduce the number of re-renderings and simplify the application architecture while maintaining reactivity.
