cormoran

Light weight library to manage JSONP calls using Promises

Install

Download the distribution version and include it on your web project or add it as a dependency

npm install cormoran --save

Use

If you know how Promises in JavaScript work and what is a JSONP call, then you don't need much else.

Require the package or use the global cormoran namespace and run getpassing a url, pipe a then statement to handle the data you've received and catch just in case something goes wrong.

var cormoran = require('cormoran');
 
cormoran
    .get('https://api.github.com/users/jeremenichelli')
    .then(function(data) {
        console.log(data);
    })
    .catch(function(e) {
        console.error(e);
    });

Configuration

As the callback name and query can changed depending on the API you're trying to reach you can change both of them running this two methods before using the get method.

naming

cormoran.naming('JSONP_CALLBACK');

query

cormoran.query('?callback');

Following the first example the final url would be https://api.github.com/users/jeremenichelli?callback=JSONP_CALLBACK0, a number will be added at the end of every callback name to make them unique.

Notes

Since this library relies on Promises remember to include a polyfill for browsers which don't support this feature. I recommend this one https://github.com/jakearchibald/es6-promise developed by Jake Archibald.
