A HookMap, called when generating the specified stats item.

• Type: HookMap<SyncBailHook<[Object, any, StatsFactoryContext], undefined>>
• Arguments:
  • Object: result stats item object which properties should be added.
  • Class: the original data of the stats item
  • StatsFactoryContext: generating context

type StatsFactoryContext = {
  type: string;
  makePathsRelative?: ((arg0: string) => string) | undefined;
  compilation?: Compilation | undefined;
  cachedGetErrors?: ((arg0: Compilation) => JsStatsError[]) | undefined;
  cachedGetWarnings?: ((arg0: Compilation) => JsStatsWarning[]) | undefined;
};

For the following example, the customProperty attribute is added in the finally generated stats.compilation through MyPlugin:

compilation.hooks.statsFactory.tap('MyPlugin', (statsFactory, options) => {
  statsFactory.hooks.extract
    .for('compilation')
    .tap('MyPlugin', (object, compilation) => {
      object.customProperty = MyPlugin.getCustomValue(compilation);
    });
});

• Type: HookMap<SyncWaterfallHook<[any[], StatsFactoryContext], undefined>>
• Arguments:
  • any[]: generated stats item result
  • StatsFactoryContext: generating context
