NativeScript plugin for OkHttp

OkHttp is an HTTP client that supports:

HTTP/2 and SPDY support allows all requests to the same host to share a socket.
Connection pooling reduces request latency (if SPDY isn’t available).
Transparent GZIP shrinks download sizes.
Response caching avoids the network completely for repeat requests.

Installation

Run the following command from the root of your project:

$ tns plugin add nativescript-okhttp

This command automatically installs the necessary files, as well as stores nativescript-okhttp as a dependency in your project's package.json file.

Usage

To use the social share module you must first require() it. After you require() the module you have access to its APIs.

var okHttp = require("nativescript-okhttp");

API

getString(url)

The getString() method downloads a URL as a string.

var okHttp = require("nativescript-okhttp");
function pageLoaded(args) {
    var result = okHttp.getString("http://www.google.com/");
    console.log(result);
}
exports.pageLoaded = pageLoaded;

getJSON(url)

The getString() method downloads a URL as a string.

var okHttp = require("nativescript-okhttp");
function pageLoaded(args) {
    var json = okHttp.getJSON("https://api.github.com/gists/c2a7c39532239ff261be");
    console.log("JSON url: " + json.url);
}
exports.pageLoaded = pageLoaded;

getImage(url)

The getImage() method returns an image as a stream from a remote URL.

In this example, we will download an image from umgur (http://i.imgur.com/sXG9IHW.jpg) and we will share it ot Facebook using a social share plugin by @tjvantoll (https://github.com/tjvantoll/nativescript-social-share).

var socialShare = require("nativescript-social-share");
var imageSource = require("image-source");
var okHttp = require("nativescript-okhttp");
function pageLoaded(args) {
    var inputStream = okHttp.getImage("http://i.imgur.com/sXG9IHW.jpg");
    var image = imageSource.fromData(inputStream);
    socialShare.shareImage(image);
}
exports.pageLoaded = pageLoaded;

Future versions will include

Actual asynchronous support. I couldn't figure out how async calls in Android translate to JavaScript. That's why I hacked it with

var policy = new android.os.StrictMode.ThreadPolicy.Builder().permitAll().build();
android.os.StrictMode.setThreadPolicy(policy);

which prevents you from dealing with android.os.NetworkOnMainThreadException. This will be fixed in the next version.

TypeScript support.
