##Set-up: ###Using npm

Recomended

1. Use npm install react-native-spotify from the directory of your project in your command line.

2. Download the Spotify IOS SDK beta 17 here and unzip it.

3. Open your react native project in Xcode and drag the unzipped Spotify.framework file into the Frameworks group in your Xcode project (create the group if it doesn’t already exist). In the import dialog, tick the box for Copy items into destinations group folder (or Destination: Copy items if needed).

4. Please folow the instructions on the "Creating Your Client ID, Secret and Callback URI" and "Setting Up Your Build Environment" sections of the Spotify iOS SDK Tutorial

Important Note! When adding frameworks to the list in the "Link Binary With Libraries" section you wll need to add WebKit.framework in addition to those mentioned in the tutorial.

5. Go to node-modules/react-native-spotify/ and copy the following files to the ios directory of your project:
   • SpotifyLoginViewController.m
   • SpotifyLoginViewController.h
   • SpotifyAuth.m
   • SpotifyAuth.h

##How to use:

//You need to import NativeModules to your view
import { NativeModules } from 'react-native';

//Assign our module from NativeModules and assign it to a variable
var SpotifyAuth = NativeModules.SpotifyAuth;

class yourComponent extends Component {
	//Some code ...

	someMethod(){
    //You need this to Auth a user, without it you cant use any method!

    const options = {
		clientID: 'your-clientID',
		redirectURL: 'your-app-schema://callback',
		requestedScopes: ['streaming',...]
	};

	SpotifyAuth.login(options, (error) => {
		if (error) {
          //handle error
        } else {
          //handle success
        }
	});
}
