OAuth 2 login plugin for NativeScript

Library for interacting with OAuth 2.0 in NativeScript applications that provides simplified client access with a OAuth providers that support the OAuth 2.0 protocol such as Microsoft Live accounts, Microsoft Graph, Office 365, Facebook, Cloud Foundry UAA instances, LinkedIn, and Google (Google is a work in progress due to some of their restrictions).

NEW: Now supports NativeScript 3.0.0!

Tested against Microsoft Live, Office 365, Microsoft Graph API, Facebook, LinkedIn and private instances of UAA.

Prerequisites

Office 365 / Microsoft Graph API

For logging in with your Office 365 account, you should have an Office 365 Account admin account. If you don't have one yet, you can get a free trial here.

Watch a video tutorial for setting up the NativeScript OAuth plugin and registering you app with Microsoft.

Register your mobile app here. This will require you to login with your Office 365 account. You can then click the big "Add an app" button and go through the steps listed there, starting with giving you app a name. On the app creation screen, you need to do 3 things:

1. Click the "Add Platform" button and select "Mobile application"
2. Copy the "Client Id" GUID from the Mobile Application section.
3. Click "Save" at the bottom.

Facebook account

For logging in with your Facebook account, you should have a Facebook developer account. If you don't have one yet, you can get one here.

Keep an eye out on my YouTube channel for a video on how to set up Facebook with with plugin.

Register your mobile app by following the wizard under "My Apps" -> "Add a new app".

1. Go to https://developers.facebook.com/apps and create a new app
2. If you see the Product Setup page, select Facebook login
3. Make sure to turn ON the option "Embedded Browser OAuth Login"
4. Click Save
5. Copy the App ID and the App Secret from the Dashboard page to bootstrap your app. These will be the ClientID and CLientSecret respectively.

LinkedIn Account

For logging in with your LinkedIn account, you should have a LinkedIn developer account. If you don't have one yet, you can get one here.

1. Click on My Apps and login with your LinkedIn credentials or click on Join Now to create a new account.
2. Once logged in click on Create Application.
3. Fill out all fields with the app's information and Click submit.
4. If everything goes well you should get your app's authentication keys which consists of a client id and a client secret.
5. In this page, make sure to add an Authorized Redirect URL. (This can be any url starting with http:// or https://).
6. Copy the Authentication Keys and the Authorized Redirect URL.

Cloud Foundry User Account and Authentication (UAA)

You will need to have a Cloud Foundry account to deploy your instance of UAA.

Setup

Add TypeScript to your NativeScript project if you don't already have it added. While this is not a requirement, it's highly recommended. If you want to watch a video on how to convert your existing JavaScript based NativeScript app to TypeScript, watch it here.

From the command prompt go to your app's root folder and execute:

npm install nativescript-oauth --save

Usage

If you want a quickstart, you can start with one of two demo apps:

• TypeScript Demo App
• Angular Demo App

Bootstrapping

We need to do some wiring when your app starts. If you are not using Angular, open app.ts and add the following code before application.start();

If you are using Angular, then open your main.ts file and add the following code before platformNativeScriptDynamic().bootstrapModule(AppModule);

TypeScript

import * as tnsOAuthModule from 'nativescript-oauth';

For Office365 login, include the following lines

var o365InitOptions : tnsOAuthModule.ITnsOAuthOptionsOffice365 = {
    clientId: 'e392f6aa-da5c-434d-a42d-a0e0a27d3955', //client id for application (GUID)
    scope: ['Files.ReadWrite', 'offline_access'] //whatever other scopes you need
};

tnsOAuthModule.initOffice365(o365InitOptions);

For Facebook login, include the following lines

var facebookInitOptions : tnsOAuthModule.ITnsOAuthOptionsFacebook = {
    clientId: '1119818654921555',
    clientSecret: 'bbb58f212b51e4d555bed857171c9aaa',
    scope: ['email'] //whatever other scopes you need
};

tnsOAuthModule.initFacebook(facebookInitOptions);

For UAA login, include the following lines

var uaaInitOptions: tnsOAuthModule.ITnsOAuthOptionsUaa = {
    authority: 'https://my-uaa-instance.com',    
    redirectUri: 'myAppDomain://authcallback',
    clientId: 'my-client-id',
    clientSecret: 'my-client-secret',
    scope: ['uaa.resource', 'uaa.user'],
    cookieDomains: ["myAppDomain://"],
    basicAuthHeader: "Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
}

tnsOAuthModule.initUaa(uaaInitOptions);

For LinkedIn login, include the following lines

var linkedInInitOptions : tnsOAuthModule.ITnsOAuthOptionsLinkedIn = {
    clientId: '',
    clientSecret: '',
    scope: ['r_basicprofile'] //Leave blank and the default scopes will be used 
};

tnsOAuthModule.initLinkedIn(linkedInInitOptions);

Logging in

In your view controller or component (or wherever you will have a handler to respond to the login user action) you will reference the nativescript-oauth module again and call the login function.

import * as tnsOAuthModule from 'nativescript-oauth';
...
tnsOAuthModule.login()
    .then(()=>{
        console.log('logged in');
        console.dir("accessToken " + tnsOAuthModule.accessToken());
    })
    .catch((er)=>{
        //do something with the error
    });

When you make API calls you can use the ensureValidToken function, which will also ask you to authenticate, if the token is expired.

tnsOAuthModule.ensureValidToken()
    .then((token: string)=>{
        console.log('token: ' + token);
    })
    .catch((er)=>{
        //do something with the error
    });

Contributing

1. Fork the nativescript-oauth repository on GitHub
2. Clone your fork
3. Change directory to nativescript-oauth
4. Run npm install in the root folder to install all npm packages for the plugin
5. Run tsc in the root folder to build the plugin TypeScript
6. Edit the /demo/package.json file: "nativescript-oauth" : "../" - this will point the demo project to use the local oauth plugin instead of the one hosted on npm.
7. Run npm install in the demo folder to install all npm packages for the demo (these are also shared by the plugin, so they are needed to build)
8. Replace the ClientId in the app.ts file of the demo with your own ClientId
9. Run the demo project
