Facebook Login Migration

Migration Guide from @capacitor-community/facebook-login to @capgo/capacitor-social-login

Installation

1. Remove the old package:

   npm uninstall @capacitor-community/facebook-login

2. Install the new package:

   npm install @capgo/capacitor-social-login
   npx cap sync

Code Changes

Import Changes

import { FacebookLogin } from '@capacitor-community/facebook-login';
import { SocialLogin } from '@capgo/capacitor-social-login';

Initialization

// Old package required no explicit initialization in code
// Configuration was done only in native platforms

// New package requires explicit initialization
await SocialLogin.initialize({
  facebook: {
    appId: 'YOUR_FACEBOOK_APP_ID',        // Required for web and Android
    clientToken: 'YOUR_CLIENT_TOKEN'       // Required for Android
  }
});

Login

const FACEBOOK_PERMISSIONS = ['email', 'public_profile'];
const result = await FacebookLogin.login({ permissions: FACEBOOK_PERMISSIONS });

const result = await SocialLogin.login({
  provider: 'facebook',
  options: {
    permissions: ['email', 'public_profile'],
    limitedLogin: false,
    nonce: 'optional_nonce'
  }
});

Response Type Changes

The response object structure has changed. Here’s how to handle the new response:

// Old response type
interface FacebookLoginResponse {
  accessToken: {
    applicationId: string;
    userId: string;
    token: string;
    expires: string;
  };
  recentlyGrantedPermissions: string[];
  recentlyDeniedPermissions: string[];
}

// New response type
interface FacebookLoginResponse {
  provider: 'facebook';
  result: {
    accessToken: {
      token: string;
      applicationId?: string;
      expires?: string;
      userId?: string;
      permissions?: string[];
      declinedPermissions?: string[];
    } | null;
    idToken: string | null;
    profile: {
      userID: string;
      email: string | null;
      friendIDs: string[];
      birthday: string | null;
      ageRange: { min?: number; max?: number } | null;
      gender: string | null;
      location: { id: string; name: string } | null;
      hometown: { id: string; name: string } | null;
      profileURL: string | null;
      name: string | null;
      imageURL: string | null;
    };
  };
}

Checking Login Status

const result = await FacebookLogin.getCurrentAccessToken();
const isLoggedIn = result && result.accessToken;

const status = await SocialLogin.isLoggedIn({
  provider: 'facebook'
});
const isLoggedIn = status.isLoggedIn;

Logout

await FacebookLogin.logout();

await SocialLogin.logout({
  provider: 'facebook'
});

Platform Specific Changes

Android Setup

1. The Android setup remains similar, but configuration is now done through the plugin’s initialize method:

// AndroidManifest.xml changes remain the same
// strings.xml become irrelevant
// Additionally initialize in your code:
await SocialLogin.initialize({
  facebook: {
    appId: 'your-app-id',
    clientToken: 'your-client-token'  // New requirement
  }
});

iOS Setup

1. The iOS setup in AppDelegate.swift remains the same:

import FBSDKCoreKit

// In application:didFinishLaunchingWithOptions:
FBSDKCoreKit.ApplicationDelegate.shared.application(
    application,
    didFinishLaunchingWithOptions: launchOptions
)

// In application:openURL:options:
ApplicationDelegate.shared.application(
    app,
    open: url,
    sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
    annotation: options[UIApplication.OpenURLOptionsKey.annotation]
)

2. The Info.plist configuration remains the same:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb[APP_ID]</string>
        </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string>[APP_ID]</string>
<key>FacebookClientToken</key>
<string>[CLIENT_TOKEN]</string>
<key>FacebookDisplayName</key>
<string>[APP_NAME]</string>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fbauth</string>
    <string>fb-messenger-share-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

Breaking Changes

1. Explicit initialization is now required
2. Response object structure has changed significantly
3. Client token is now required for Android
4. Different method names and parameter structures
5. Error handling and error types have changed
