What is the best way to retrieve a specific number of documents from MongoDB?

I am currently facing an issue with my code that is returning all news related to a company. However, I only want the first 15 elements. Is there a way to achieve this? The following code snippet retrieves all news for a company using the google-news-json npm package.

export default async function handler(req, res) {
  try {
    let news = await googleNewsAPI.getNews(googleNewsAPI.SEARCH, req.body.companyName, 'en-US')
    res.status(200).json(news)

  } catch (err) {
    res.status(500).json({ error: 'Failed to fetch news' })
  }
}

Answer №1

For a comprehensive understanding of google news features, it is essential to thoroughly review the API reference documentation. Within the documentation, you will come across query parameters (such as ?q=15 or ?count=no.of.items) that can be appended after your API key to specify the number of objects you wish to retrieve in the fetch URL.

Answer №2

To follow @iceweasel's advice would typically be the best course of action. However, this particular package does not have Google support and instead appears to scrape HTML from Google News directly to return results in JSON format. As a result, it lacks many standard features such as limiting the number of items returned.

If you are okay with the network cost of fetching all 100 items (which is the default behavior), you can extract the first 15 results from the API's response by using:

let top15 = news.items.slice(0, 15)
