     Historically we have allowed specifying `NODE_PATH` environment variable as a way to allow “absolute imports”. For example, running `NODE_PATH=src npm start` in Bash or `set NODE_PATH=src&&npm start` in Windows Cmd would let you import anything inside `src` without specifying a relative path. However, we found a few nasty edge cases when Node.js core modules end up being in `NODE_PATH` and erroneously become bundled. As a result the build would crash on some systems when some libraries are imported. To fix this, we now only honor relative paths from `NODE_PATH` in Create React App. This means the existing use case for absolute imports is still supported (`src` in the example above is relative), but absolute paths in `NODE_PATH` (such as paths to Node.js core modules) will be ignored.

+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc.) into your project as dependencies in `package.json`. Technically, the distinction between dependencies and development dependencies is pretty arbitrary for front-end apps that produce static bundles.
 
 In addition, it used to cause problems with some hosting platforms that didn't install development dependencies (and thus weren't able to build the project on the server or test it right before deployment). You are free to rearrange your dependencies in `package.json` as you see fit.
