Package Exports

mu.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mu.js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

/* Initialize jQuery on remote document */

µ('http://example.com/').then($ => {
    // $ = cheerio (jQuery)
    console.log(
        $('body').html()
    )
})

/* For options, use object passed to request module */
µ({
    url: 'http://example.com', 
    timeout: 5000, 
    strictSSL: true // require valid SSL
}).then($ => {
    console.log(
        $('title').text()
    )
})

/* From local file */
µ.fromFile('page.html').then($ => {
    console.log(
        $('title').text()
    )
})

/* From local file synchronously */
let $ = µ.fromFileSync('/var/www/index.html')
$('h2').each(function() { /* make text red in every <h2> */
    $(this).css('color', 'red')
})

/* From a string */
let $ = µ.fromString('<div><h2>Title of a document</h2><p>Description of a document.</p></div>') // does not even require <html></html>
$('div').html() /* <h2>Title of a document</h2><p>Description of a document.</p> */

/* Full document outerHTML*/
$.html()

/* Initialize jQuery on remote document synchronously */
const $ = µ.sync('http://reddit.com')
$('title').text() // reddit: the front page of the internet

/* Fetch worldnews headlines from Reddit */
µ('https://www.reddit.com/r/worldnews/').then($ => {
    $('p[class="title"]').each(function() {
        let a = $('a', $(this)) // every <a> in this <p>
        console.log({
            title: a.text(), 
            url: a.attr('href')
        })

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
})
