babel-plugin-transform-react-jsx-location

Adds a data-source attribute to JSX tags containing the file name and line number of the original source.

Use this plugin to locate which file is generating an element in your page/app. Simply right click on an element in your favourite browser, then hit Inspect and the location of the source is revealed in the data-source attribute.

This plugin is intended to help with debugging while developing; use in production is not recommended!
