Profiling with Vue DevTools Performance Tab
Recording component updates, identifying unnecessary re-renders, component timing.
Why Profile
Before optimizing you must know where time goes. Vue DevTools includes a performance/timeline view that records component renders so you can find wasted work instead of guessing.
Installing Vue DevTools
Install the browser extension or run the standalone app. In Vite projects the vite-plugin-vue-devtools plugin adds an in-app inspector.
