It's aimed at building full dynamic and reactive web applications, not just isolated widgets.Does Marko support both client-side and server-side rendering?Yes, Marko is isomorphic and supports both client-side rendering (CSR) and server-side rendering (SSR) out of the box, as reflected in its own topics and design.
Yes, Marko is isomorphic and supports both client-side rendering (CSR) and server-side rendering (SSR) out of the box, as reflected in its own topics and design.What does a Marko component look like?A component is written as an HTML-like .marko file, e.g. click-count.marko, mixing markup with component logic such as counters and click handlers.
