XHR is a wrapper around Titanium's HTTPClient. It works perfectly with REST API endpoints and has a built in cache system that you can use for your requests. But it also can be use for any HTTP requests, you can even cache remote images.

In your app.js (or elsewhere), call:

//init xhr.js
var XHR = require("xhr");
var xhr = new XHR();

GET and DELETE calls share the same structure

xhr.GET("http://freegeoip.net/json/", onSuccessCallback, onErrorCallback, options);
xhr.DELETE("http://freegeoip.net/json/", onSuccessCallback, onErrorCallback, options);

POST and PUT also share structure, only 1 added field as opposed to GET/DELETE

xhr.POST("http://freegeoip.net/json/", data, onSuccessCallback, onErrorCallback, options);
xhr.PUT("http://freegeoip.net/json/", data, onSuccessCallback, onErrorCallback, options);

In the 4 API call methods you can set options, but doing this every time might be a bit frustrating. Especially if you want authentication for every API call. (or other options). You can set it globally like this

xhr.setStaticOptions(options);

If you do specify options in an API call, it will not ignore global options. This might be useful if all but 1 API call should be authenticated for example.

• async (default true) - If an API call should be async or not
• ttl (default false) - Seconds the API response should be cached (only works with GET()
• shouldAuthenticate (default false) - Should the call be made with authentication? BASIC Auth & oAuth supported
• oAuthToken - oAuth token. Only works if shouldAuthenticate is true
• username - Username for BASIC authentication. Only works if shouldAuthenticate is true and oAuthToken is not set
• password - Password for BASIC authentication. See username
• contentType (default application/json)- contentType for API call.
• parseJSON (default false) - Should provided data for POST() and PUT() be stringified and response (for all methods) be parsed.
• returnXML (default false) - Do you expect XML returned, put this to true
• debug (default false) - Do you want Ti.API.info to show API calls made
• requestHeaders (default []) - Add custom request headers to the request

For some examples please check out the examples.js file. Or browse around the xhr.js file. You can find in there support for GET, POST, PUT and DELETE

To add extra, custom, requestHeaders to the http request, you can set an array like this:

    xhr.setStaticOptions({
        requestHeaders: [
            {
                key: 'myCustomId',
                value: 'myCustomValue'
            }
        ],
        debug: true
    });

This will set the requestHeader like you would do previously:

    xhr.setRequestHeader('myCustomId', 'myCustomValue');

Apart from the RESTful way of interacting with your API endpoints, this module also includes the following helper methods:

• url: (required) The URL you want removed from the cache manager

Finds the cached document of the given url (if any) and removes it from the cache manager. This method is useful if you are not satisfied with the results you got at the time.

Goes through all the cached documents and delete everything that has been expired (if their TTL timestamp is less than the current time)

This method returns the count of deleted documents

Goes through all the documents and deletes everything

This method returns the count of deleted documents

Previously get, post, put and destroy methods were used. They still work but are deprecated.
