$ npm install jsonp2
API
jsonp(url, opts, fn)
url
(String
) url to fetchopts
(Object

+ incremented counter)
fn
callback
The callback is called with err, data
parameters.
If it times out, the err
will be an Error
object whose message
is
Timeout
.
Returns a function that, when called, will cancel the in-progress jsonp request
(fn
won't be called).
Just a tiny patch for original jsonp repo.
If fn
callback isn't passed into jsonp
, it will return a Promise.
The original jsonp return will be replaced by a Promise instance.
jsonp(url, opts); // return a promise.
jsonp(url, opts).then((data) => {}).catch((err)=>{})
If fn
parameter is passed in, everything are still running like original jsonp module.
