react-native-lock

NPM version CI Status

Auth0 is an authentication broker that supports social identity providers as well as enterprise identity providers such as Active Directory, LDAP, Google Apps and Salesforce.

react-native-lock is a wrapper around Lock's implementations for iOS and Android ready to use for React Native

Requirements

iOS

Android

  • Minimum SDK 16

Installation

Run npm install --save react-native-lock to add the package to your app's dependencies.

iOS

react-native cli

Run react-native link react-native-lock so your project is linked against your Xcode project & install Lock for iOS using CocoaPods and run react-native run-ios

Manually

  1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
  2. Go to node_modules ➜ react-native-lock and add A0RNLock.xcodeproj
  3. In XCode, in the project navigator, select your project. Add libA0RNLock.a to your project's Build Phases ➜ Link Binary With Libraries
  4. Click A0RNLock.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Header Search Paths and make sure it contains $(SRCROOT)/../react-native/React, $(SRCROOT)/../../React, ${SRCROOT}/../../ios/Pods/Headers/Public and ${SRCROOT}/../../ios/Pods/Headers/Public/Lock - all marked as recursive.
  5. Inside your ios directory add a file named Podfile with the following content
  6. Run pod install --project-directory=ios
  7. Run react-native run-ios

CocoaPods Warning

If you get the following warning.

[!] The `<YourAppName> [Debug]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The `<YourAppName> [Release]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

Click <YourAppName>.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Other Linker Flags and replace the value -ObjC with the value $(inherited) for your Application's Target.

Compile error react-native >=0.26.0

If you are using a react-native version >=0.26.0, you might encounter the following error while trying to run the project

"std::terminate()", referenced from:
        ___clang_call_terminate in libReact.a(RCTJSCExecutor.o)

React Native introduced some C++ code so we need to tell Xcode to include use those symbols for compile. First click <YourAppName>.xcodeproj in the Project Navigator to show your project's target (at least one for your app). Then for each of the targets do the following:

  • Go the Build Settings tab, and make sure All is toggled on (instead of Basic)
  • Look for Other Linker Flags and add the flag -lc++ for all configurations

If your project was created using react-native init command, you will have two targets (app & tests) so make sure BOTH of them has the correct flags

CocoaPods with uses_framework! flag

This more of a hack than an actual solution. We recommend to avoid including Lock as a dynamic framework unless you have a very good reason to do that.

After setting up react-native-lock either Manually or using react-native cli you need to open your iOS project with Xcode and follow these steps:

  1. Click A0RNLock.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Framework Search Paths and make sure it contains $BUILD_DIR/$CONFIGURATION$EFFECTIVE_PLATFORM_NAME/Lock
  2. Change to the A0RNLock.xcodeproj target tab Build Phases, and in the section Link Binary with Libraries click the + and add Lock.framework and make sure it's Status is set to optional
  3. In the project navigator, select your project (should be the top one) and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic') and look for Other Linker Flags and make sure the value -ObjC is listed there

Android

react-native cli

Run react-native link react-native-lock so your project is linked against your Android project

In your file android/app/build.gradle, inside the android section add the following

packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
}

Then in your android/app/src/main/AndroidManifest.xml add the following inside <application> tag

<!--Auth0 Lock-->
<activity
  android:name="com.auth0.lock.LockActivity"
  android:theme="@style/Lock.Theme"
  android:screenOrientation="portrait"
  android:launchMode="singleTask">
</activity>
<!--Auth0 Lock End-->
<!--Auth0 Lock Embedded WebView-->
<activity
    android:name="com.auth0.identity.web.WebViewActivity"
    android:theme="@style/Lock.Theme">
</activity>
<!--Auth0 Lock Embedded WebView End-->
<!--Auth0 Lock Passwordless-->
<activity
    android:name="com.auth0.lock.passwordless.LockPasswordlessActivity"
    android:theme="@style/Lock.Theme"
    android:screenOrientation="portrait"
    android:launchMode="singleTask">
</activity>
<activity
    android:name="com.auth0.lock.passwordless.CountryCodeActivity"
    android:theme="@style/Lock.Theme">
</activity>
<!--Auth0 Lock Passwordless End-->

And finally run react-native run-android

Manually

In your file android/settings.gradle add the following

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

In the file android/app/build.gradle add a new dependency

dependencies {
  //Other gradle dependencies...
  compile project(':react-native-lock')
}

And in the same file inside the android section

packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
}

This fixes the error `Error: duplicate files during packaging of APK

Then in the file MainApplication.java add the following Java import

import com.auth0.lock.react.LockReactPackage;

In react-native versions older than 0.29 you should add do this in MainActivity.java instead

and add Lock's React Native module

    /**
     * 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(),
            //Other RN modules
            new LockReactPackage()
        );
    }

Then in your android/app/src/main/AndroidManifest.xml add the following inside <application> tag

<!--Auth0 Lock-->
<activity
  android:name="com.auth0.lock.LockActivity"
  android:theme="@style/Lock.Theme"
  android:screenOrientation="portrait"
  android:launchMode="singleTask">
</activity>
<!--Auth0 Lock End-->
<!--Auth0 Lock Embedded WebView-->
<activity
    android:name="com.auth0.identity.web.WebViewActivity"
    android:theme="@style/Lock.Theme">
</activity>
<!--Auth0 Lock Embedded WebView End-->
<!--Auth0 Lock Passwordless-->
<activity
    android:name="com.auth0.lock.passwordless.LockPasswordlessActivity"
    android:theme="@style/Lock.Theme"
    android:screenOrientation="portrait"
    android:launchMode="singleTask">
</activity>
<activity
    android:name="com.auth0.lock.passwordless.CountryCodeActivity"
    android:theme="@style/Lock.Theme">
</activity>
<!--Auth0 Lock Passwordless End-->

For more information and configuration options you should see the Lock.Android docs

And finally run react-native run-android

Usage

Let's require react-native-lock module:

var Auth0Lock = require('react-native-lock');

And initialize it with your Auth0 credentials that you can get from our dashboard

var lock = new Auth0Lock({clientId: "YOUR_CLIENT_ID", domain: "YOUR_DOMAIN"});

Email/Password, Enterprise & Social authentication

lock.show({}, (err, profile, token) => {
  console.log('Logged in!');
});

And you'll see our native login screen

Lock.png

Avoid WebView for Social Auth

In order to make Lock use the OS browser to perform Web Auth you will need to pass the attribute useBrowser when you build Lock like

var lock = new Auth0Lock({clientId: "YOUR_CLIENT_ID", domain: "YOUR_DOMAIN", useBrowser: true});

Then you need to configure both your iOS and Android project following the instructions detailed below.

IMPORTANT: This feature only works with iOS 9 or later.

iOS

In the file AppDelegate.m add the following import on the top (next to the other imports of the file)

#import "A0LockReact.h"

and then inside the AppDelegate implementation add the following method

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
  return [[A0LockReact sharedInstance] handleURL:url sourceApplication:nil];
}

And finally in the file Info.plist add the following entry

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string>auth0</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>{Bundle Identifier}</string>
    </array>
  </dict>
</array>

Where the Bundle identifier can be found in the same file under the key CFBundleIdentifier like

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

Android

In the file AndroidManifest find where the LockActivity is declared and insde the activity tags add the following

<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:scheme="a0{your lowercase auth0 client id}" android:host="{your auth0 domain}"/>
</intent-filter>

And make sure Lock's activity launch mode is singleTask

TouchID (iOS Only)

lock.show({
  connections: ["touchid"]
}, (err, profile, token) => {
  console.log('Logged in!');
});

And you'll see TouchID login screen

Lock.png

Because it uses a Database connection, the user can change it's password and authenticate using email/password whenever needed. For example when you change your device.

SMS Passwordless

lock.show({
  connections: ["sms"]
}, (err, profile, token) => {
  console.log('Logged in!');
});

And you'll see SMS Passwordless login screen

Lock.png

Email Passwordless

lock.show({
  connections: ["email"]
}, (err, profile, token) => {
  console.log('Logged in!');
});

And you'll see Email Passwordless login screen

Upgrading

If you are upgrading your react-native version just run react-native upgrade and overwrite all conflicts (option a or overwrite this and all others).

If you have custom code in any of the conflict files, like AppDelegate.m, it's probably best to backup a copy to apply those changes later.

Then run react-native link react-native-lock and follow the same steps like you did the first time you installed the library.

API

Lock

####.show(options, callback) Show Lock's authentication screen as a modal screen using the connections configured for your applications or the ones specified in the options parameter. This is the list of valid options:

  • closable (boolean): If Lock screen can be dismissed
  • disableSignUp (boolean): default to false, if true will hide the signup button
  • disableResetPassword (boolean): default to false, if true will hide the reset password button
  • connections ([string]): List of enabled connections to use for authentication. Must be enabled in your app's dashboard first.
  • authParams (object): Object with the parameters to be sent to the Authentication API, e.g. scope.

The callback will have the error if anything went wrong or after a successful authentication, it will yield the user's profile info and tokens.

####.authenticationAPI() Returns Auth0 Authentication API client that can be used to refresh user's token, obtain user information or call Auth0 delegation.

For more info check react-native-auth0

####.usersAPI(token) Returns Auth0 Users API client using a valid user's token for Management API. With this client you can update user's metadata or link two user accounts.

For more info check react-native-auth0
