How to use the @angular-devkit/build-angular/src//angular-cli-files/models/webpack-configs.getAotConfig function in @angular-devkit/build-angular

tsConfig,
      tsConfigPath,
      supportES2015,
    };

    const webpackConfigs: {}[] = [
      getCommonConfig(wco),
      getBrowserConfig(wco),
      getStylesConfig(wco),
      getStatsConfig(wco),
      require(`${wco.root}/webpack.config.js`)
    ];

    if (wco.buildOptions.main || wco.buildOptions.polyfills) {
      const typescriptConfigPartial = wco.buildOptions.aot
        ? getAotConfig(wco, host)
        : getNonAotConfig(wco, host);
      webpackConfigs.push(typescriptConfigPartial);
    }

    return webpackMerge(webpackConfigs);
  }
