Library for interacting with OAuth 2.0 in NativeScript applications that provides simplified direct client access with a OAuth providers that support the OAuth 2.0 protocol such as Microsoft, Facebook, and Google, but not limited to any login providers, and even allows you to plug in your own. This library doesn't use any native libraries and relies only on what comes in the box - making it really lightweight.
NEW: This is the new version of the old nativescript-oauth plugin
Tested against Microsoft, Facebook, and Google providers. More providers are coming soon. Thanks to all those who contributed providers to the old plugin - please do the same for this one.
Some providers are OpenId certified (Google, Microsoft) so they are a bit more secure in that they don't have to store the client secret on the client (which can always be pwned by folks that are savvy enough to get into your app). Google doesn't allow client secrets to be passed and requires an out-of-app browser to be used for auth. This plugin supports this method for any providers that require it, but there are a few extra configuration steps that have to be performed to get this working, more on that below.
Facebook doesn't support OpenId and works with the in-app WebView implementation of the auth process. So while this requires less configuration, there is an slight security risk of keeping your client secret in the app. If you have strict security requirements, you have to implement Facebook login by using your backend as a proxy between this plugin and Facebook auth servers.
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.
Keep an eye out on my YouTube channel for a video on how to set up Facebook with with plugin.
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:
- Click the "Add Platform" button and select "Mobile application"
- Copy the "Client Id" GUID from the Mobile Application section.
- Click "Save" at the bottom.
Microsoft login will work either with the in-app webview method, in which case your redirectUri config property can be set to urn:ietf:wg:oauth:2.0:oob. Or it can use the more secure method that doesn't require a client secret, but it will need to have a custom URL scheme registered (see below).
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".
- Go to https://developers.facebook.com/apps and create a new app
- If you see the Product Setup page, select Facebook login
- Make sure to turn ON the option "Embedded Browser OAuth Login"
- Click Save
- Copy the App ID and the App Secret from the Dashboard page to bootstrap your app. These will be the ClientID and ClientSecret respectively.
For logging in with your Google account, you should have a Google 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 Google with with plugin.
Register your mobile app by following the wizard in the Developer Console. (more info coming soon)
Google login will only work with the out-of-app browser. You must register a custom URL scheme for your app (see below).
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.
- Click on
My Appsand login with your LinkedIn credentials or click on Join Now to create a new account. - Once logged in click on
Create Application. - Fill out all fields with the app's information and Click
submit. - If everything goes well you should get your app's authentication keys which consists of a client id and a client secret.
- In this page, make sure to add an
Authorized Redirect URL. (This can be any url starting with http:// or https://). - Copy the Authentication Keys and the Authorized Redirect URL.
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-oauth2 --save
If you want a quickstart, you can start with one of two demo apps:
When your app starts up, you'll have to register one or more auth providers to use with the nativescript-oauth2 plugin. You'll use the code below to register the providers.
If you are using NativeScript Core, open app.ts and add the following registration code before application.start();
If you are using Angular AND you are NOT using <page-router-outlet, you'll need to enable frames in order for the plugin to open up a new native page with a login screen. To do that open your main.ts file. You will need to explicitly use frames, so make sure to pass an options object to platformNativeScriptDynamic with the createFrameOnBootstrap flag set to true, like this.
// main.ts
platformNativeScriptDynamic({ createFrameOnBootstrap: true }).bootstrapModule(
AppModule
);You don't need to do this if you already have <page-router-outlet> in your component.
then add add the registration code below somewhere before you call login, most likely in your Auth service, as in the demo-angular project.
If you are using NativeScript-Vue, then you'll have to add this registration code somewhere when your app bootstraps. A demo app is coming soon.
// This is the provider registration example code
import { configureTnsOAuth } from "nativescript-oauth2";
import {
TnsOaProvider,
TnsOaProviderOptionsFacebook,
TnsOaProviderFacebook,
TnsOaProviderOptionsGoogle,
TnsOaProviderGoogle,
TnsOaProviderOptionsMicrosoft,
TnsOaProviderMicrosoft
} from "nativescript-oauth2/providers";
function configureOAuthProviderGoogle(): TnsOaProvider {
const googleProviderOptions: TnsOaProviderOptionsGoogle = {
openIdSupport: "oid-full",
clientId:
"932931520457-buv2dnhgo7jjjjv5fckqltn367psbrlb.apps.googleusercontent.com",
redirectUri:
"com.googleusercontent.apps.932931520457-buv2dnhgo7jjjjv5fckqltn367psbrlb:/auth",
urlScheme:
"com.googleusercontent.apps.932931520457-buv2dnhgo7jjjjv5fckqltn367psbrlb",
scopes: ["email"]
};
const googleProvider = new TnsOaProviderGoogle(googleProviderOptions);
return googleProvider;
}
function configureOAuthProviderFacebook(): TnsOaProvider {
const facebookProviderOptions: TnsOaProviderOptionsFacebook = {
openIdSupport: "oid-none",
clientId: "691208554415641",
clientSecret: "d8725ac416fa1bb1917ccffd1670e3c7",
redirectUri: "https://www.facebook.com/connect/login_success.html",
scopes: ["email"]
};
const facebookProvider = new TnsOaProviderFacebook(facebookProviderOptions);
return facebookProvider;
}
configureTnsOAuth([
configureOAuthProviderGoogle(),
configureOAuthProviderFacebook()
]);The plugin comes with helpful interfaces that you can implement for the providers as well as the options that can be passed into each provider's constructor. You don't have to use these interfaces, but they are helpful guides. The code above shows these interfaces.
The last call to configureTnsOAuth() takes an array of providers and registers them as available for use.
When you're ready to login, or as a response to a tap event on a login button, you can create a new instance of the TnsOAuthClient and call loginWithCompletion() on the instance, passing in the provider you want to login with. The provider is of the type TnsOaProviderType, or it can be a string 'google', 'facebook', 'microsoft', etc.
import { TnsOAuthClient, ITnsOAuthTokenResult } from "nativescript-oauth2";
const client = new TnsOAuthClient(providerType);
client.loginWithCompletion((tokenResult: ITnsOAuthTokenResult, error) => {
if (error) {
console.error("back to main page with error: ");
console.error(error);
} else {
console.log("back to main page with access token: ");
console.log(tokenResult);
}
});After login is done, the completion handler will be called with the results.
If you don't see an auth provider that you need, you can just implement your own.
If your provider supports OpenId, simply implement your provider's options by extending the TnsOaUnsafeProviderOptions interface if your provider is not Open Id compliant, or the TnsOaOpenIdProviderOptions interface if your provider IS Open Id compliant.
export interface TnsOaMyCustomProviderOptions extends TnsOaUnsafeProviderOptions { }Then you can create your provider class by implementing the TnsOaProvider interface:
export class TnsOaProviderMyCustomProvider implements TnsOaProvider {
public options: TnsOaProviderOptions;
public openIdSupport: OpenIdSupportNone = "oid-none";
public providerType = "myCustomProvider";
public authority = "https://www.facebook.com/v3.1/dialog";
public tokenEndpointBase = "https://graph.facebook.com";
public authorizeEndpoint = "/oauth";
public tokenEndpoint = "/v3.1/oauth/access_token";
public cookieDomains = ["facebook.com"];
constructor(options: TnsOaMyCustomProviderOptions) {
this.options = options;
}
public parseTokenResult(jsonData): ITnsOAuthTokenResult {
return jsonData;
}
}Finally, you'll use your provider when you register it with the app.
// app.ts
import * as application from "tns-core-modules/application";
import { configureOAuthProviders } from "./auth-service";
configureOAuthProviders();
application.run({ moduleName: "app-root" });// auth-service.ts
export function configureOAuthProviders() {
const myCustomProvider = configureOAuthProviderMyCustomProvider();
configureTnsOAuth([myCustomProvider]);
}
function configureOAuthProviderMyCustomProvider(): TnsOaProvider {
const facebookProviderOptions: TnsOaMyCustomProviderOptions = {
openIdSupport: "oid-none",
clientId: "<your client/app id>",
clientSecret: "<your client secret>",
redirectUri: "<redirect Uri>",
scopes: ["email"]
};
const facebookProvider = new TnsOaProviderMyCustomProvider(facebookProviderOptions);
return facebookProvider;
}If you are using an OpenId certified provider and need to use an out-of-app browser to authenticate, then you must register a custom URL scheme with your app. This is easy to do with NativeScript. The first step is to register your custom scheme with your provider when you register your app.
To register a custom URL scheme for Android, open your Android app resources, which are in this path: app/App_Resources/Android/src/main/AndroidManifest.xml. The AndroidManifest.xml file used to be right in the Android folder, but now it's been moved down a bit. It's still the same file though. Find the <application> section and add the attribute android:launchMode="singleTask". Then inside the activity named com.tns.NativeScriptActivity, add a new <intent-filter> section with your scheme AND your path. Here is an example of the entire <application>
section:
<application android:name="com.tns.NativeScriptApplication" android:allowBackup="true" android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/AppTheme" android:launchMode="singleTask">
<activity android:name="com.tns.NativeScriptActivity" android:label="@string/title_activity_kimera" android:configChanges="keyboardHidden|orientation|screenSize" android:theme="@style/LaunchScreenTheme">
<meta-data android:name="SET_THEME_ON_LAUNCH" android:resource="@style/AppTheme" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<!-- Custom Path data -->
<data android:path="/auth" android:scheme="com.googleusercontent.apps.932931520457-buv2dnhgo7jjjjv5fckqltn367psbrlb"/>
<data android:path="/auth" android:scheme="msalf376fa87-64a9-89a1-8b56-e0d48fc08107"/>
</intent-filter>
</activity>
<activity android:name="com.tns.ErrorReportActivity"/>
</application>Notice in the config above, I've registered TWO custom URL schemes for my app - this is the <data> element with the path and scheme attributes.
To register a custom URL scheme for iOS, open your iOS app resources, which are in this path: app/App_Resources/iOS/Info.plist. In the key/value dictionary in this file, add a key for CFBundleURLTypes, if it's not already there. And add the value for that key as an array. The entire addition is listed here:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>CFBundleURLName</key>
<string>org.nativescript.testnsazmobaplugin</string>
<key>CFBundleURLSchemes</key>
<array>
<string>msalf376fa87-64a9-49a1-8b57-e0d48fc08107</string>
<string>fb691208554415647</string>
<string>com.googleusercontent.apps.932931520457-buv2dnhgo7jjjjv5fckqltn367psbrlb</string>
</array>
</dict>
</array>
Notice that for the key CFBundleURLSchemes, there are three string listed as custom URL schemes, all of them will open your app.
