Rel Scraper
This is just a simple function to scrape relationships from a url. Both via link headers and html tags.
You can provide just a url or optionally add a html string or headers object to prevent making unneeded http requests.
Usage
Running the rel scraper function returns a promise which will resolve with an object containing keys and arrays of values of found rels.
The returned object will look something like this:
{
me: [
'https://twitter.com/grantcodes',
'https://facebook.com/grantcodes'
],
micropub: ['https://grant.codes/micropub']
}
All keys will be lowercase and all urls will be absolute.
Basic url
relParser('https://grant.codes')
.then(rels => {
console.log('grant.codes rels', rels)
})
.catch(err => console.log('Rel scraper error', err));
With html string
relParser('https://grant.codes', '<a href="https://www.twitter.com/grantcodes/" rel="me">Twitter</a>')
.then(rels => {
console.log('Me', rels.me)
})
.catch(err => console.log('Rel scraper error', err));
With http link header parsing
const headers = {
link: '<https://grant.codes/micropub>; rel="micropub"'
};
relParser('https://grant.codes', null, headers)
.then(rels => {
console.log('Micropub', rels.micropub)
})
.catch(err => console.log('Rel scraper error', err));
