Summary

Extractor Interface Base contract for extraction utilities that pull data from DOM / HTML elements. Extractors do NOT classify field types — they only gather raw data (labels, selectors, signals) from the page. TInput — what the extractor receives (e.g. HTMLElement, FormField). TResult — what the extractor returns (e.g. string, LabelResult). Concrete implementations: selectorExtractor : Extractor<Element, string> signalsExtractor : Extractor<Partial, string> labelExtractor : Extractor<HTMLElement, LabelResult | undefined>

Source Code

export interface Extractor<TInput, TResult> {
  /** Unique identifier for this extractor. */
  readonly name: string;

  /** Run the extraction logic and return the result. */
  extract(input: TInput): TResult;
}
