React Developer Tools is a Chrome DevTools extension for the open-source React JavaScript library. It allows you to inspect the React component hierarchies in the Chrome Developer Tools.
You will get two new tabs in your Chrome DevTools: "Components ⚛" and "Profiler ⚛".
The Components tab shows you the root React components that were rendered on the page, as well as the subcomponents that they ended up rendering.
By selecting one of the components in the tree, you can inspect and edit its current props and state in the panel on the right. In the breadcrumbs you can inspect the selected component, the component that created it, the component that created that one, and so on.
If you inspect a React element on the page using the regular Elements tab, then switch over to the React tab, that element will be automatically selected in the React tree.
The Profiler tab allows you to record performance information.
Inspect the latest comments and rating distribution.
Store average score: 4.0. The bars below are calculated from synced review text only, so they may be empty for extensions that have public ratings but no synced comments yet.

new version is not working
The extension doesn't show my component tree
Despues de la ultima actualizacion (19/4/21) la opcion de "rendered by" ya no muestra toda la informacion que mostraba antes, siendo esta, como herramienta de trabajo MUY util a la hora de identificar problemas. Dejando eso de lado (muy triste por cierto) es una extension que uso todos los dias en la jornada laboral. Gracias por eso.
