The API to manipulate the DOM is very imperative and therefore not properly match the dynamic of the DOM structure. RxJS is around for more than 10 years, but still not part of the official DOM API. Within this talk, we will discuss a more reactive approach for DOM operations. This added reactivity is extremely beneficial when it comes to complex scenarios like pre-optimistic updates and proper loading indicators. By leveraging the power of RxJS, without any other JS-Framework, one will face the benefits when it comes to application design. This agnostic approach will deliver many insights on how to architecture complex scenarios with RxJS. Additionally, it demonstrates many different patterns one could apply to every project that already uses RxJS.
