• jaubourg is working on it

link $.xhr

link Trac

• I will ping about that, i think they made progress last week

link Promises/A+ compat for jaubourg's pull request

• m_gol got it mostly working
• some fails related to invalid args
• need a solution for dfd.done( fnThrows ).then( neverCalled )
  • keep a separate list of callbacks for .then() vs .done()?
• need analog to Promise.unhandledRejection proposal from Domenic
  • http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2014-September/297601.html
  • (questions about whether onerror or unhandledRejections is best)
• see if jauborg and m_gol can finish this
• Promises error telemetry - Mike to reach out to Domenic

link $.xhr

• markelog and gibson042 to create some examples based on typical ajax usage
• review at next meeting

Location: In person, Chicago jQCon

link Versioning

• If we are going npm we should obey semantic versioning
• The .then() change will be breaking
• Might as well remove other things like .andSelf()
• New versioning
  • 1.x now jquery-legacy-3.x
  • 2.x now jquery 3.x

link Deferred pull request for Promise/A compat on .then()

• Comments on the PR
• A branch with tests applied:
  • https://github.com/jquery/jquery/tree/standard-then-tests (run grunt promises-aplus-tests)

link xhr

• Design goal: allow standalone usage
• Simple xhr module in a wrapper

jQuery.xhr = require("jquery-xhr");
jQuery.xhr.Promise = window.Promise || function( executor ) {
    var dfd = jQuery.Deferred();
    try {
        executor( dfd.resolve, dfd.reject );
    } catch ( ex ) {
        dfd.reject( ex );
    }
    return dfd.promise();
};

• Simple case: jQuery.xhr( url, options ).then( handlerA ).then( handlerB )
• beforeSend case:

xhr = jQuery.xhr( url, { autosend: false } ).set( … );
jQuery.xhr({ url: ... });
jQuery.xhr( url );
xhr.then( handlerA );
xhr.send( body ).then( handlerB )

• Super-advanced case:

xhr = jQuery.xhr( url, { autosend: false } );
xhr.then( handlerA );
if ( badFeeling(xhr.getNative()) ) { xhr.abort(); }
xhr.send( body ).then( handlerB );
Promise.resolve( xhr ).then( … )
jQuery.xhr( url ).send({ ... }), jQuery.xhr( url )

• Does an unsent Promise that has mutability violate the Promise/A+ spec? Or does the mutability only apply to the resolution? No. Does not appear to apply to the returned promise, which can be augmented, only to the resolved value of the promise
  • https://people.mozilla.org/~jorendorff/es6-draft.html#sec-promisenew
  • https://github.com/promises-aplus/promises-spec
• options necessary to functionality: method, user, pass, body, query (RFC), beforeSend
• options nice to keep: cache, ifModified, headers
• jxrPromise: .abort(), .xhr property
  • Rejects on: Exception, timeout, abort
• what about 4xx/5xx? or a 0 (network error)
  • implied success: jQuery.xhr( url ).then( jQuery.xhr.rejectHTTPError )
  • implied failure: jQuery.xhr( url ).catch( jQuery.xhr.ifResponse )
• Resolved value: raw native xhr
• Rejected value: Error object, potentially with .xhr property, .options object

• gibson042 proposal seems like it should work!
• Checking with jaubourg on his availability, markelog and gibson042 are interested

link $.xhr

• Below it is a chaining interface?
  • exposes (not wraps) underlying xhr method
• limited compat with old IE and ActiveX method?
  • (See discussion in IRC)
