url-loader

Encode files as Data URLs

This webpack configuration uses url-loader to process image files. If an image is smaller than 8KB, it will be converted to a Base64 encoded Data URL and inlined in the code. Larger images will be handled by file-loader, which is the default fallback.

module.exports = {
  module: {
    rules: [
      {
        test: /\.(png|jpg|gif)$/i,
        use: [
          {
            loader: 'url-loader',
            options: {
              limit: 8192
            }
          }
        ]
      }
    ]
  }
};

Fallback to file-loader

In this example, url-loader is configured with a fallback option. If the file size exceeds the limit, file-loader is used to emit the file to the output directory and returns the public URL. The 'name' option specifies the naming convention for the emitted files.

module.exports = {
  module: {
    rules: [
      {
        test: /\.(png|jpg|gif)$/i,
        use: [
          {
            loader: 'url-loader',
            options: {
              limit: 8192,
              fallback: 'file-loader',
              name: '[path][name].[ext]'
            }
          }
        ]
      }
    ]
  }
};
