react-native-auth0

React Native toolkit for Auth0 API, compliant with RFC 8252

Requirements

React Native 0.26+

Installation

Install react-native-auth0 using npm

npm install react-native-auth0 --save

Or via yarn

yarn add react-native-auth0

then you need to link the native module in react-native-auth0

react-native link react-native-auth0

Configuration

This section is for those that want to use Web Authentication, if you dont need it just ignore this section.

Android

In the file android/app/src/main/AndroidManifest.xml you must make sure the MainActivity of the app has a launchMode value of singleTask and that it has the following 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" />
    <data
        android:host="YOUR_AUTH0_DOMAIN"
        android:pathPrefix="/android/${applicationId}/callback"
        android:scheme="${applicationId}" />
</intent-filter>

So if you have samples.auth0.com as your Auth0 domain you would have the following MainActivity configuration:

<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:launchMode="singleTask"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustResize">
<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" />
    <data
        android:host="samples.auth0.com"
        android:pathPrefix="/android/${applicationId}/callback"
        android:scheme="${applicationId}" />
</intent-filter>
</activity>

For more info please read react native docs

In order to reduce the potential for conflict which may be caused by the presence of differing versions of the Android support libraries, you may wish to configure project-wide properties. Setting the Compile and Target SDK versions, Build Tools version, and Support Library version in your root project's build.gradle file will make react-native-auth0 and many other React Native modules use them.

iOS

Inside the ios folder find the file AppDelegate.[swift|m] add the following to it

#import <React/RCTLinkingManager.h>

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
  return [RCTLinkingManager application:application openURL:url
                      sourceApplication:sourceApplication annotation:annotation];
}

Inside the ios folder open the Info.plist and locate the value for CFBundleIdentifier, e.g.

<key>CFBundleIdentifier</key>
<string>org.reactjs.native.example.$(PRODUCT_NAME:rfc1034identifier)</string>

and then register a URL type entry using the value of CFBundleIdentifier as the value of CFBundleURLSchemes

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>None</string>
        <key>CFBundleURLName</key>
        <string>auth0</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>org.reactjs.native.example.$(PRODUCT_NAME:rfc1034identifier)</string>
        </array>
    </dict>
</array>

The <string> value should be the literal value of the Bundle Identifier with no $ variables, for example: samples.auth0.com.

The value org.reactjs.native.example.$(PRODUCT_NAME:rfc1034identifier) is the default for apps created with React Native CLI, you may have a different value.

Callback URL(s)

Callback URLs are the URLs that Auth0 invokes after the authentication process. Auth0 routes your application back to this URL and appends additional parameters to it, including a token. Since callback URLs can be manipulated, you will need to add this URL to your Application's Allowed Callback URLs for security. This will enable Auth0 to recognize these URLs as valid. If omitted, authentication will not be successful.

Callback URLs must have a valid scheme value as defined by the specification. A "Redirect URI is not valid" error will raise if this format is not respected.

Go to the Auth0 Dashboard, select your application and make sure that Allowed Callback URLs contains the following:

iOS

{YOUR_BUNDLE_IDENTIFIER}://${YOUR_AUTH0_DOMAIN}/ios/{YOUR_BUNDLE_IDENTIFIER}/callback

Android

{YOUR_APP_PACKAGE_NAME}://{YOUR_AUTH0_DOMAIN}/android/{YOUR_APP_PACKAGE_NAME}/callback

Usage

import Auth0 from 'react-native-auth0';

const auth0 = new Auth0({ domain: '{YOUR_AUTH0_DOMAIN}', clientId: '{YOUR_CLIENT_ID}' });

Web Authentication

Log in

auth0
    .webAuth
    .authorize({scope: 'openid email', audience: 'https://{YOUR_AUTH0_DOMAIN}/userinfo'})
    .then(credentials => console.log(credentials))
    .catch(error => console.log(error));

This snippet sets the audience to ensure OIDC compliant responses, this can also be achieved by enabling the OIDC Conformant switch in your Auth0 dashboard under Application / Settings / Advanced OAuth. For more information please check this documentation.

Log out

auth0
    .webAuth
    .clearSession()
    .catch(error => console.log(error));

Authentication API

Important: Database Connection Authentication

Since June 2017 new Clients no longer have the Password Grant Type* enabled by default. If you are accessing a Database Connection using passwordRealm then you will need to enable the Password Grant Type, please follow this guide.

Login with Password Realm Grant

auth0
    .auth
    .passwordRealm({username: "[email protected]", password: "password", realm: "myconnection"})
    .then(console.log)
    .catch(console.error);

Get user information using user's access_token

auth0
    .auth
    .userInfo({token: 'user access_token'})
    .then(console.log)
    .catch(console.error);

Getting new access token with refresh token

auth0
    .auth
    .refreshToken({refreshToken: 'user refresh_token'})
    .then(console.log)
    .catch(console.error);

Create user in database connection

auth0
    .auth
    .createUser({email: '[email protected]', username: 'username', password: 'password', connection: 'myconnection'})
    .then(console.log)
    .catch(console.error);

Management API (Users)

Patch user with user_metadata

auth0
    .users('user token')
    .patchUser({id: 'user_id', metadata: {'first_name': 'John', 'last_name': 'Doe'}})
    .then(console.log)
    .catch(console.error);

Get full user profile

auth0
    .users('user token')
    .getUser({id: "user_id"})
    .then(console.log)
    .catch(console.error);

What is Auth0?

Auth0 helps you to:

• Add authentication with multiple authentication sources, either social like Google, Facebook, Microsoft Account, LinkedIn, GitHub, Twitter, Box, Salesforce, amont others, or enterprise identity systems like Windows Azure AD, Google Apps, Active Directory, ADFS or any SAML Identity Provider.
• Add authentication through more traditional username/password databases.
• Add support for linking different user accounts with the same user.
• Support for generating signed Json Web Tokens to call your APIs and flow the user identity securely.
• Analytics of how, when and where users are logging in.
• Pull data from other sources and add it to the user profile, through JavaScript rules.

Create a free Auth0 Account

1. Go to Auth0 and click Sign Up.
2. Use Google, GitHub or Microsoft Account to login.
