Uncommenting the code

I have commented on social login code because some people find it difficult to integrate. To add social login you have to install native plugins and uncomment the code

Uncomment Facebook and GooglePlus import in src/app/app.module.ts and src/pages/account/login/login.ts

//import { Facebook } from '@ionic-native/facebook';
//import { GooglePlus } from '@ionic-native/google-plus';

Uncomment Facebook and GooglePlus in the providers section of src/app/app.module.ts

// Facebook,
// GooglePlus,

Add GooglePlus, Facebook constructor src/pages/account/login/login.ts file

private googlePlus: GooglePlus, private fb: Facebook

Uncomment Social login in src/pages/account/login/login.ts file

 /* facebookLogin() {
        this.facebookSpinner = true;
       this.fb.login(['public_profile', 'user_friends', 'email']).then((response) => {
            this.service.sendToken(response.authResponse.accessToken).then((results) => {
                this.facebookSpinner = false;
                this.nav.setRoot(TabsPage);
                
                this.functions.showAlert('success', 'Logged in successfully');
            });
        }).catch((error) => {
            console.log(error)
            this.facebookSpinner = false;
            this.functions.showAlert('Error', error);
        });
    }
    gmailLogin() {
        this.googleSpinner = true;
        this.googlePlus.login({
            'scopes': '',
            'webClientId': this.config.webClientId,
            'offline': true
        }).then((res) => {
             this.gres = res;
             console.log(this.gres);
            this.googleSpinner = false;
            this.values.avatar = res.imageUrl;
            
            this.service.googleLogin(res).then((results) => {
                this.functions.showAlert('success', 'Logged in successfully');
                this.nav.setRoot(TabsPage);
            });
        }).catch((err) => {
            this.googleSpinner = false;
            this.error = err;
            this.functions.showAlert('Error', err);
            console.error(err);
        });
    }*/

Uncomment Social login buttons in src/pages/account/login/login.html file

Google Authentication

Get your credentials from Google.
Install the Google native plugin.

1. Get your credentials from Google.

let’s start with the iOS one,

Choose your project. Click settings icon and then select project settings

Click on ADD APP and then choose a platform

It will ask you an iOS Bundle ID, to get it, go into your app’s config.xml file and copy the package id you’re using, it’s the one that looks like (id=”com.ionicframework.something”) from your config.xml file.

Click REGISTER APP. It will generate GoogleService-Info.plist file.

Click on Download GoogleService-Info.plist file, which is a config file for iOS.

After downloading GoogleService-Info.plist file click on Continue > Continue > FINISH.

Copy GoogleService-Info.plist file to your project root directory.

You will get REVERSED_CLIENT_ID from the downloaded GoogleService-Info.plist file. REVERSED_CLIENT_ID is required while installing Google native plugin at the later stage.

Once we add iOS app, we need to add Android app.

Click ADD APP and choose android platform

It will ask you an Android Bundle ID, to get it, go into your app’s config.xml file and copy the package id you’re using, it’s the one that looks like (id=”com.ionicframework.something”) from your config.xml file.

Click REGISTER APP. It will generate google-services.json file

Click on Download google-services .json file, which is a config file for Android.

After downloading google-services.json file click on Continue > FINISH

Copy google-services.json file to your project root directory

You will get CLIENT_ID from the downloaded google-services.json file.

Add CLIENT_ID in src/providers/config.ts file

webClientId: any = '456352511209-fbam1kgj6354543fgfdfdstvfidbs1.apps.googleusercontent.com';

2. Install the GooglePlus Cordova Plugin.

We will get REVERSED_CLIENT_ID in GoogleService-Info.plist file

Run the following command to install GooglePlus Cordova plugin

$ ionic cordova plugin add cordova-plugin-googleplus --variable REVERSED_CLIENT_ID=CLIENT_ID

$ npm install --save @ionic-native/google-plus@4

Facebook Authentication

Make sure you've registered your Facebook app with Facebook and have an APP_ID

Retrieve the App ID and App Name

2. Add android and ios platforms. Go to settings>basics as shown below and click +Add Platform.

3. Fill the required fields while adding android and ios platforms and save changes.

4. In the final step, Change the status of the app from development mode to Live.

Install the Cordova and Ionic Native plugins. where App ID and App Name are the values of the Facebook Developer portal.

$ ionic cordova plugin add cordova-plugin-facebook4 --variable APP_ID="123456789" --variable APP_NAME="myApplication"

$ npm install --save @ionic-native/facebook@4
