Description

Clear and concise description of the problem

When working with Vite, HMR updates happen frequently, but there’s currently no centralized way to observe or track them over time.

Suggested solution

Introduce a dedicated DevTools page that records and visualizes HMR updates in real time.

This view could include:

  • A timeline or log of HMR events
  • The files/modules that triggered each update
  • Frequency of updates (to detect noisy modules)
  • Optional visual highlighting of affected areas in the UI (#231)

Start by reviewing the existing Vite DevTools page structure and how HMR events are exposed. Define the event timeline, affected files or modules, update frequency view, and optional UI highlighting, then verify that the page records and visualizes updates in real time.
