#supports

• Type: Supports Types
• Optional: true
• Default: undefined

This option controls detailed analysis behavior, such as BannerPlugin compatibility, bundle parsing, and gzip size calculation.

#supportsTypes

type ISupport = {
  banner?: boolean;
  parseBundle?: boolean;
  brotli?: boolean | { brotliLevel?: number };
  gzip?:
    | boolean
    | {
        gzipLevel?: number;
      };
};

#banner

• Type: boolean
• Default: true

If supports.banner is enabled, Rsdoctor will enable compatibility logic for BannerPlugin. For more details, please refer to: Supports BannerPlugin

#parseBundle

• Type: boolean
• Default: true

In some large repositories, the execution time of parsing the bundle is too long. Since the Parse Bundle analysis utilizes AST parsing and processing, it can be time-consuming when there are a large number of output files. If this capability is not necessary, it can be selectively disabled using the supports.parseBundle configuration. An example is shown below:

chain.plugin('Rsdoctor').use(RsdoctorRspackPlugin, [
  {
    supports: {
      parseBundle: false,
    },
  },
]);

Disabling the Parse Bundle capability will only affect the visibility of the Bundled Size and Bundled Code of the modules in the bundle:

#gzip

• Type: boolean | { gzipLevel?: number }
• Default: true

Controls whether Rsdoctor calculates gzip sizes for assets and modules. This calculation only affects the size data in the Rsdoctor report; it does not modify or compress the build output.

Rsdoctor skips gzip size calculation while the compiler is running in watch mode. Run a one-time build when you need gzip sizes for production bundle analysis.

Gzip size calculation is enabled by default with a compression level of 6. Set gzip to an object to customize gzipLevel, which must be an integer between 0 and 9:

new RsdoctorRspackPlugin({
  supports: {
    gzip: {
      gzipLevel: 9,
    },
  },
});

Set gzip to false to disable gzip size calculation:

new RsdoctorRspackPlugin({
  supports: {
    gzip: false,
  },
});

#brotli

• Type: boolean | { brotliLevel?: number }
• Default: false

Calculates Brotli sizes for assets and modules in the report, including the size cards and treemap. This does not compress or modify build output. Like gzip, Brotli calculation is skipped in watch mode.

Set brotli: true or brotli: {} to use quality 6, or specify brotliLevel as an integer from 0 to 11. Higher levels can increase analysis time. Disable gzip independently when you only need Brotli sizes:

new RsdoctorRspackPlugin({
  supports: {
    gzip: false,
    brotli: { brotliLevel: 11 },
  },
});
