hackernews-scraper

Scrape hacker news comments and posts using the Algolia API.

Usage

from hackernews_scraper import CommentScraper

CommentScraper.getComments(since=1394039447)

The above will return a generator that will yield one comment at a time. It will keep on going until there are no more comments to fetch, or until it reaches the 50 pages limit set by hacker news. In the latter case, a TooManyItemsException will be raised.

If the hacker news API response is missing any required fields, the scraper will raise KeyError.
