linkfo 0.0.2+3

Crawls and gathers open graph and twitter cards information from links

linkfo

Retrieve basic information from links

Getting Started

install linkfo:

    linkfo: <latest_version>

Linkfo uses sealed unions to handle the case of possible matches:

const url = 'https://www.youtube.com/watch?v=45MIykWJ-C4';

final response = await client.get(Uri.parse(url));
final info = Scraper.parse(body: response.body, url: url);

info.map(
  openGraph: (info) {
    print(info.title);
    // ...
  },
  twitterCards: (info) {
    // ...
  },
  amazon: (info) {
    // ...
  },
);

If you're certain you'll only be encountering one type of protocol, you can use that corresponding parser instead.

const url = 'https://www.imdb.com/title/tt0117500/';

final response = await client.get(Uri.parse(url));
final scraper = TwitterCardsScraper(body: response.body, url: url);
final info = scraper.scrape();

print(info.title);

Note

This api is in early development and might change drastically as I look for the best way to return parsed information. This includes Twitter cards which are more like sealed unions themselves as they can be only one of four categories.
