Читает <run_dir>/hotspot_cpu.jsonl, hotspot_react.jsonl, modal.jsonl, modal_renders.jsonl (сырые данные в git не
|
||
попадают) и пишет <out>/hotspots.json и hotspots.md:
|
||
- react: на шаг колеса - коммиты, рендеры компонентов, рендеры ForwardRef(Styled(td)); топ-10 компонентов по self_ms;
|
||
- cpu: main thread на шаг (профайлер включён - абсолютные значения выше, чем в scroll.spec);
|
||
- filter: хронология мутаций DOM контейнера после ввода фильтра (ответ на «filter did not stabilize»);
|
||
- cssgrowth: CSS-правила документа, @media, вызовы window.matchMedia и main thread на шаг по циклам;
|
||
- модалки (если есть): клик -> кадр и рендеры.
