*/Update: 30 october 2019
Added additional method sync for synchronous initialization. See example.
Update: 1 april 2018
Now includes 3 additional methods: fromFile, fromFileSync and fromString.
Update: 4 september 2018
Resolved instance of jQuery (cheerio) now includes reference to HTTP response, which in turn includes a reference to the HTTP request. This can be used for stuff like reading header information (Content-type, cache-control, ...) and detect redirect(s).
let url = 'http://example.com'
µ(url).then($ => {
console.log($.response.headers)
let destination = $.response.request.uri.href
if(destination != url)
console.log(`we were redirected from ${url} to ${destination}`)
// the rest of your $ code
})
