jsonp-client

jsonp minimal client for the browser (1.4K or 0.74K gzipped) and Node.js

On Node.js jsonp JavaScript code will run on a sandbox.

Installation

$ npm install jsonp-client

Usage

Include the library on Node.js

var jsonpClient = require('jsonp-client');

or include the script for browser usage

 <script src="https://raw.github.com/bermi/jsonp-client/master/dist/jsonp-client.min.js" type="text/javascript"></script>

On the browser you must supply a valid callback on the URL. On Node.js the callback will be taken from the script contents.

Single jsonp resource URL

jsonpClient(url, function (err, data) {
});

Multiple URLs

jsonpClient(url1, url2, function (err, data1, data2) {
});

or as an array of URLs

jsonpClient([url1, url2], function (err, data1, data2) {
});

Callbacks

jsonp-client assumes you will explicitly define a callback on the URL. This is a design decision aimed to simplify the interface of the jsonp-client library.

Here is a sample method for automatically add callbacks to your URL's

function addCallback(url) {
    // The URL already has a callback
    if (url.match(/callback=[a-z]/i)) {
        return url;
    }
    return url + ("&callback=cb" + Math.random()).replace('.', '');
}
