state-inspector

To inspect React component state without devtools, traverse the component tree to read props, state, and hooks directly. This method captures live UI data, enabling debugging and verification of data flow across user interactions independently.

Frontend state inspection works with Vue, Angular, Svelte, and vanilla JS by detecting the active framework on the page. It traverses component trees and reads state natively, reporting framework versions when available for accurate debugging.

You can snapshot Redux, Vuex, Pinia, Zustand, and MobX stores to perform state diffing. Capturing before and after state snapshots traces data flow across user actions, verifying UI correctness and highlighting changes in the application state.

The best way to debug frontend UI state changes is capturing before and after state snapshots across user interactions. This approach detects the active framework, traverses component trees, and diffs state stores to verify data flow and UI correctness.

Detect the frontend framework and state management library by running an inspection tool on the target page. It automatically identifies React, Vue, Angular, or Svelte environments, reports versions, and maps the active component tree for state analysis.

Frontend state inspection may fail without devtools if the component tree cannot be traversed, but this approach reads props, state, and hooks directly from the page environment. It detects frameworks like Svelte and vanilla JS independently to bypass missing devtools.
