This project was bootstrapped with Create React App using the "single-page-app" template. It was then "ejected" so that the configuration files are locally editable.
To enable the @fullstory/babel-plugin-annotate-react plugin we edited the fullstory-babel-plugin-annotate-react/samples/single-page-app/config/webpack.config.js file. Since this sample is using the local plugin we use ../.. as the plugin name (around line 376) but you should use the npm package name of @fullstory/babel-plugin-annotate-react.
To test this sample:
cd fullstory-babel-plugin-annotate-react/samples/single-page-app/
npm install
npm run start
A browser window should open and you can compare the source components in fullstory-babel-plugin-annotate-react/samples/single-page-app/src/App.js to the rendered DOM. Look for the data-component, data-element, and data-source-file attributes added by this plugin.
