Design of MPX Partial Runtime Capability Enhancement for Mini‑Program Development

The article describes MPX’s partial runtime capability‑enhancement design, which adds modern web‑framework features such as props, default slots and event forwarding to Didi’s recompilation‑based mini‑program framework by enabling on‑demand runtime rendering for selected components, generating minimal base templates, respecting the native dual‑thread event model, and exploring server‑component‑inspired mixed rendering while keeping performance overhead low.
