-You can **`import` a file right in a JavaScript module**. This tells Webpack to include that file in the bundle. Unlike CSS imports, importing a file gives you a string value. This value is the final path you can reference in your code, e.g. as the `src` attribute of an image or the `href` of a link to a PDF.

This value is the final path you can reference in your code, e.g. as the `src` attribute of an image or the `href` of a link to a PDF.
 
 To reduce the number of requests to the server, importing images that are less than 10,000 bytes returns a [data URI](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs) instead of a path. This applies to the following file extensions: bmp, gif, jpg, jpeg, and png. SVG files are excluded due to [#1153](https://github.com/facebook/create-react-app/issues/1153). You can control the 10,000 byte threshold by setting the `IMAGE_INLINE_SIZE_LIMIT` environment variable as documented in our [advanced configuration](advanced-configuration.md).

 This is handy if you don't want to load SVG as a separate file. Don't forget the curly braces in the import! The `ReactComponent` import name is significant and tells Create React App that you want a React component that renders an SVG, rather than its filename.
