@meteorrn/oauth-google v1.0.1

Draft Accounts Google for Meteor React Native.

Prerequisites

Have RN >= 0.60.0

Installation

In your react native app, run the following command to install it:

npm install @meteorrn/oauth-google

In your meteor app, make sure you have installed the following packages:

meteor add accounts-base accounts-password accounts-google service-configuration

And add this configuration in a server's file:

import { Meteor } from 'meteor/meteor';
import { ServiceConfiguration } from 'meteor/service-configuration';

if (Meteor.isDevelopment) {
    if (Meteor.settings.private?.OAUTH?.google) {
        process.env.OAUTH_GOOGLE_CLIENT_ID = Meteor.settings.private.OAUTH.google.CLIENT_ID;
        process.env.OAUTH_GOOGLE_SECRET = Meteor.settings.private.OAUTH.google.SECRET;
    } else {
        console.warn('[App name] - Google OAuth settings are not configured.');
    	process.env.OAUTH_GOOGLE_CLIENT_ID = '';
    	process.env.OAUTH_GOOGLE_SECRET = '';
    }
}

ServiceConfiguration.configurations.upsert({ service: 'google' }, {
    $set: {
        clientId: process.env.OAUTH_GOOGLE_CLIENT_ID,
        loginStyle: "popup",
        secret: process.env.OAUTH_GOOGLE_SECRET
    }
});

Make sure you have environment variables configured in your settings-settings.json file:

{
  "private": {
    "ROOT_URL": "http://localhost",
    "OAUTH": {
      "google": {
        "CLIENT_ID": "yourAppId",
        "SECRET": "yourSecret"
      }
    }
  }
}

Configuration for Android/iOS

Then follow the Android guide and iOS guide

Usage

In the below example, you will have to load your client ids (for Android and iOS) from a .env file located in your project root since react-native-config is being used.

projectRoot/.env

GOOGLE_CLIENT_ID_IOS=<client_id_ios>.apps.googleusercontent.com
GOOGLE_CLIENT_ID_ANDROID=<client_id_android>.apps.googleusercontent.com

• GOOGLE_CLIENT_ID_IOS: You can find it in GoogleServices-Info.plist as CLIENT_ID
• GOOGLE_CLIENT_ID_ANDROID: You can find it in google-services.json as client-> oauth_client -> client_id

Login

import { Component } from 'react';
import { View } from 'react-native';
import { Config } from 'react-native-config';
import { Platform } from 'react-native';
import Meteor from '@meteorrn/core';
import '@meteorrn/oauth-google';//this should be inside of meteorrn/core package (PR is needed).
import GoogleButton from './path/to/customGoogleButton';

export default class Login extends Component {

    async handleGoogleLogin() {
        try {
            await Meteor.loginWithGoogle({
                webClientId: Platform.OS === 'ios' ? Config.GOOGLE_CLIENT_ID_IOS : Config.GOOGLE_CLIENT_ID_ANDROID
            });
            // login success, then do anything
        } catch (exception) {
            // error in login with Google
            console.error(exception);
        }
    }

    render() {
        return (
            <View>
                <GoogleButton onPress={ handleGoogleLogin }/>
            </View>
        );
    }
};

If you want to do logout, remember to use this way:

Meteor.logoutFromGoogle();

This allows to revoke access from Google Signing.
