jsonp

Tiny subset of superagent-like API to be used with jsonp requests

Installation

$ npm install tiny-jsonp

API

To construct and send request:

jsonp('http://example.com')
    .query({
        param1: 'value',
        param2: 3
    }).end(function(data) {
        console.log('This is your json:', data);
    });

Please note - you don't add callback parameter: JSONP takes care of that.

You can call query as many times as needed. New parameters will overwrite the old values.

If URL is already constructed you can also shortened form:

jsonp('http://example.com?param1=value&param2=3', function(data) {
    console.log('This is your json:', data);
});

Caveat

Chances are API that you are using already supports CORS - in that case just use superagent. JSONP is a hackish solution.

Many libraries pretend that JSONP is like any other request: jQuery magically decides between sending XRC and JSONP based on the presence of callback parameter. But JSONP does not support much of the functionality of the standard HTTP request. We just add script tag tricking browser into sending HTTP GET. No other HTTP methods are supported, errors handling is limited, and you have no control over HTTP headers sent with request.
