// including this file in a package allows for the use of import statements
// with svg files. Example: `import xSvg from 'path/xSvg.svg'`

// for use with raw-loader in Webpack.
// The svg will be imported as a raw string

declare module '*.svg' {
  const value: string;
  export default value;
}

// for use with svg-react-loader in Webpack.
// The svg will be imported as a ReactElement

// declare module '*.svg' {
//   import { HTMLAttributes } from 'react';
//   const value: React.ComponentType<HTMLAttributes<SVGElement>>;
//   export default value;
// }

// as an alternative to importing svgs one at a time, you can do a glob import
// using `context.requires`. This is a Webpack only extension. Implementation:

// import { PathExt } from '@jupyterlab/coreutils';
//
// /**
//  * Import all svgs from a directory. The input argument should be
//  * of the form `require.context('raw-loader!<path>', true, /\.svg$/)`.
//  * <path> should be a string literal path, as this is needed by `require`.
