React-native-auth0: Error: Missing NativeModule. Please make sure you run `react-native link react-native-auth0

Created on 16 Oct 2017 · 13Comments · Source: auth0/react-native-auth0

This comes up when I call a react-native-auth0 function from my Expo app

This is the function I call:

onLogin() {
    auth0.webAuth
      .authorize({
        scope: 'openid profile',
        audience: 'https://' + credentials.domain + '/userinfo'
      })
      .then(credentials => {
        Alert.alert(
          'Success',
          'AccessToken: ' + credentials.accessToken,
          [{ text: 'OK', onPress: () => console.log('OK Pressed') }],
          { cancelable: false }
        );
        this.setState({ accessToken: credentials.accessToken });
      })
      .catch(error => console.log(error));
  }

When I run react-native link react-native-auth0 this is what the console says:

C:\Users\schicdevice-mgr>react-native link react-native-auth0
Scanning folders for symlinks in C:\Users\schicdevice-mgr\node_modules (31ms)

It doesn't say anything else.

Version information:

npm 3.10.10
react-native-cli: 2.0.1
react-native: 0.48.4

Would appreciate any help at all

@bubuzzz solution worked for me.

Add new A0Auth0Package() to MainApplication.java in the

 @Override
  public List<ReactPackage> createAdditionalReactPackages() {

    // Add additional packages you require here
    return Arrays.<ReactPackage>asList(
            new A0Auth0Package(),
         .....
    );
  }

Don't forget to import import com.auth0.react.A0Auth0Package;

Also worth noting that we are NOT using Expo.

@DanSchick I have not tried with Expo. However, I believe they do not support the standard react-native link. You can read more about it in this issue https://github.com/expo/expo/issues/56
It talks about using ExponentKit to facilitate this.

Be great if you can report back. Thanks

Thanks for your response, it seems obvious in retrospect

I don't think I'm going to use ExpoKit, so I ended up using the built in Expo class featured here:

Thanks, not actually seen that before.

I have the same issue without using Expo. I get this error after running auth0.webauth.

react-native: "0.49.3"
"react-native-auth0": "^1.2.1"

@SamiChab The alternative solution in the Expo is provided in the sample above https://github.com/expo/auth0-example

In Expo if you want to link native modules you need to look into ExponentKit

I still use react native and after using react-native link, everything works fine on IOS, but not on Android. I have been hitting my head to the wall for nearly 1 week for this. After that, I downloaded the login example of React Native of Auth0 again and checked every single file to see the difference and see that I HAVE TO put the new A0Auth0Package(), into the MainApplication.java in order to make it work. This is so tricky !!!! Hopefully this will help someone later

@bubuzzz please can you create a new issue for this and tell me the steps you took/what was missing for you.
Also what version of RN are you using? I'm wondering if anything has changed in RN. Thx

I'm trying to implement Auth0 to my React Native app. Everything works fine on iOS but on Android I get the same as this issue. When I try to add A0Auth0Package to my MainApplication.java, I get an error: package com.auth0.react does not exist. How did you guys manage to get this to work for Android?
