performance.printFileSize#

• Type:

type PrintFileSizeOptions =
  | {
      /**
       * whether to print total size
       */
      total?: boolean;
      /**
       * whether to print size of each file
       */
      detail?: boolean;
      /**
       * whether to print gzip-compressed size
       */
      compressed?: boolean;
    }
  | boolean;

• Default: true

Whether to print the file sizes after production build.

Default Outputs#

The default output log is as follows:

info    Production file sizes:

  File                                    Size        Gzipped
  dist/static/js/lib-react.b0714b60.js    140.4 kB    45.0 kB
  dist/static/js/index.f3fde9c7.js        1.9 kB      0.97 kB
  dist/index.html                         0.39 kB     0.25 kB
  dist/static/css/index.2960ac62.css      0.35 kB     0.26 kB

  Total size:  143.0 kB
  Gzipped size:  46.5 kB

Disable Outputs#

If you don't want to print any information, you can disable it by setting printFileSize to false:

export default {
  performance: {
    printFileSize: false,
  },
};

Custom Outputs#

You can customize the output format through the options.

• If you don't need to output the size of each static asset, you can set detail to false. In this case, only the total size will be output:

export default {
  performance: {
    printFileSize: {
      detail: false,
    },
  },
};

• If you don't need to output the gzipped size, you can set compressed to false. This can save some gzip computation time for large projects:

export default {
  performance: {
    printFileSize: {
      compressed: false,
    },
  },
};
