linkfo 0.0.1

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:

import 'package:html/parser.dart' show parse;

const url = 'https://www.youtube.com/watch?v=45MIykWJ-C4';
final response = await client.get(Uri.parse(url));

final doc = parse(response.body);
final info = Scraper.parse(doc, url);

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

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

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

final response = await client.get(Uri.parse(url));

final doc = parse(response.body);
final scraper = TwitterCardsScraper(doc, url);

final info = scraper.scrape();

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.
