This package includes scripts and configuration used by Create React App.
Please refer to its documentation:
- Getting Started – How to create a new app.
- User Guide – How to develop apps bootstrapped with Create React App.
The modernizr config (in modernizr-config.json) is based on packages/react-scripts/polyfills.js and usage of the items in the config across apps.
The modernizr.js file is generated from the config in the prepare script when installed and published.
