Package Exports

reqwest

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 (reqwest) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Ender Support

Reqwest can be used as an Ender module. Add it to your existing build as such:

$ ender add reqwest

Use it as such:

$.ajax({ ... })

Serialize things:

$(form).serialize() // returns query string -> x=y&...
$(form).serialize({type:'array'}) // returns array name/value pairs -> [ { name: x, value: y}, ... ]
$(form).serialize({type:'map'}) // returns an object representation -> { x: y, ... }
$(form).serializeArray()
$.toQueryString({
    foo: 'bar'
  , baz: 'thunk'
}) // returns query string -> foo=bar&baz=thunk

Or, get a bit fancy:

$('#myform input[name=myradios]').serialize({type:'map'})['myradios'] // get the selected value
$('input[type=text],#specialthing').serialize() // turn any arbitrary set of form elements into a query string

jQuery and Zepto Compatibility

There are some differences between the Reqwest way and the jQuery/Zepto way.

method

jQuery/Zepto use type to specify the request method while Reqwest uses method and reserves type for the response data type.

dataType

When using jQuery/Zepto you use the dataType option to specify the type of data to expect from the server, Reqwest uses type. jQuery also can also take a space-separated list of data types to specify the request, response and response-conversion types but Reqwest uses the type parameter to infer the response type and leaves conversion up to you.

JSONP

Reqwest also takes optional jsonpCallback and jsonpCallbackName options to specify the callback query-string key and the callback function name respectively while jQuery uses jsonp and jsonpCallback for these same options.

But fear not! If you must work the jQuery/Zepto way then Reqwest has a wrapper that will remap these options for you:

reqwest.compat({
    url: 'path/to/data.jsonp?foo=bar'
  , dataType: 'jsonp'
  , jsonp: 'foo'
  , jsonpCallback: 'bar'
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

// or from Ender:

$.ajax.compat({
  ...
})

If you want to install jQuery/Zepto compatibility mode as the default then simply place this snippet at the top of your code:

$.ajax.compat && $.ender({ ajax: $.ajax.compat });

Happy Ajaxing!
