React-native-twitter-signin-franjo NPM

React Native : Twitter Signin

This package provides necessary code to get your social sign in using Twitter works with least pain possible.

Prerequisites

Go to Twitter Apps to create your app so that you can obtain API key and secret, note:

Remember to set a Callback Url, whatever will work
By default, Twitter won't allow you to grab user's email, so you have to apply for a permission for your app to retrieve user's email

Since Twitter Kit can only be used via Fabric, make sure you install Fabric properly:

iOS install Fabric according to this guide: https://docs.fabric.io/ios/fabric/getting-started.html
Android install Fabric according to this guide: https://docs.fabric.io/android/fabric/migration/android-studio.html

Fabric will use your Twitter accounts to generate API keys and tokens therefore you have to redo this every time you change your Twitter credentials.

Setup

Firstly, install the npm package:

npm install react-native-twitter-signin --save

iOS

It is pretty simple to install it for iOS:

Open you Xcode IDE
In Libraries choose Add files... and add the 2 files ios/TwitterSignin/TwitterSignin.h and ios/TwitterSignin/TwitterSignin.m in your node_modules/react-native-twitter-signin folder
Rebuild your project to make sure no build error

Android

On Android, it will use Gradle so all you need to do is to point to the correct project location:

In your ${project_dir}/android/settings.gradle add this:

include ':react-native-twitter-signin'
project(':react-native-twitter-signin').projectDir = new File(rootProject.projectDir,'../node_modules/react-native-twitter-signin/android')

In your ${project_dir}/android/app/build.gradle add this:

depedencies {
   ...
   compile project(':react-native-twitter-signin')
   ...
}

In you MainApplication.java makes use of the package as following:

        
        /**
        * A list of packages used by the app. If the app uses additional views
        * or modules besides the default ones, add more packages here.
        */
        @Override
        protected List<ReactPackage> getPackages() {
           return Arrays.<ReactPackage>asList(
             new MainReactPackage(),
             new FacebookLoginPackage(),
             new TwitterSigninPackage(),
             new RNGoogleSigninPackage(this),
             new VectorIconsPackage(),
             new RNSvgPackage()
           );
         }

Keeps in mind that all the configure is for your build tools to recognise the files. So open your Xcode and Android Studio to try making builds and make sure they pass.

Usage

Import your native module as follow:

        import React from 'react-native';
        var {
          NativeModules
          } = React;
        const { TwitterSignin } = NativeModules;
        class TwitterButton extends SocialButton {
          _twitterSignIn() {
            TwitterSignin.logIn(Constants.TWITTER_COMSUMER_KEY, Constants.TWITTER_CONSUMER_SECRET, (error, loginData) => {
              if (!error) {
              } else {
                Alert.alert('Invalid login', 'Unable to login');
              }
            });
          }
          render() {
            return (
              <Icon name='social-twitter' size={32} color='white' style={styles.icon} onPress={this._twitterSignIn.bind(this)}/>
            );
          }
        };
