Optional textDecoder

textDecoder?: TextDecoder

Methods

load

  • load(): Promise<Document[]>

  • An asynchronous method that loads the web page. If the webPath includes "item", it calls the loadComments() method to load the comments from the web page. Otherwise, it calls the loadResults() method to load the results from the web page.

    Returns Promise<Document[]>

    A Promise that resolves to an array of Document instances.

scrape

Static imports

  • imports(): Promise<{
        load: ((content, options?, isDocument?) => CheerioAPI);
    }>

  • A static method that dynamically imports the Cheerio library and returns the load function. If the import fails, it throws an error.

    Returns Promise<{
        load: ((content, options?, isDocument?) => CheerioAPI);
    }>

    A Promise that resolves to an object containing the load function from the Cheerio library.

Static scrapeAll

  • scrapeAll(urls, caller, timeout, textDecoder?, options?): Promise<CheerioAPI[]>

  • Fetches web documents from the given array of URLs and loads them using Cheerio. It returns an array of CheerioAPI instances.

    Parameters

    • urls: string[]

      An array of URLs to fetch and load.

    • caller: AsyncCaller
    • timeout: undefined | number
    • Optional textDecoder: TextDecoder
    • Optional options: CheerioOptions & {
          headers?: Record<string, string> | [string, string][] | Headers;
      }

    Returns Promise<CheerioAPI[]>

    A Promise that resolves to an array of CheerioAPI instances.
