Requirements

• Installed React Developer Tools

• Source code must be stored on local disk

How it works

The React Inspector accesses the __REACT_DEVTOOLS_GLOBAL_HOOK__ set globally by the React Devtools and finds the React Fiber in the HTML element that the inspector hovered over. The React Fiber contains information about the source code that will be added during development, so we use that information to open the VSCode.
