Getting Started

Copy a setup prompt with the install steps and the full markdown guide for this plugin.

        Set up this Capacitor plugin in the project.

Use the package manager already used by the project.
Install these package(s): `@capgo/capacitor-social-login`
Run the required Capacitor sync/update step after installation.
Read this markdown guide for the full setup steps: https://raw.githubusercontent.com/Cap-go/website/refs/heads/main/apps/docs/src/content/docs/docs/plugins/social-login/getting-started.mdx
Use that guide for platform-specific steps, native file edits, permissions, config changes, imports, and usage setup.
If that guide references other docs pages, read them too.

Install the package
Terminal window
```
bun add @capgo/capacitor-social-login
```
Sync with native projects
Terminal window
```
bunx cap sync
```

Initialize in app startup

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

await SocialLogin.initialize({
  google: {
    webClientId: 'your-google-web-client-id',
    iOSServerClientId: 'your-google-server-client-id',
    mode: 'online',
  },
  apple: {
    clientId: 'your-apple-service-id',
    useProperTokenExchange: true,
    useBroadcastChannel: true,
  },
  facebook: {
    appId: 'your-facebook-app-id',
  },
  twitter: {
    clientId: 'your-twitter-client-id',
    redirectUrl: 'myapp://oauth/twitter',
  },
  oauth2: {
    github: {
      appId: 'your-github-client-id',
      authorizationBaseUrl: 'https://github.com/login/oauth/authorize',
      accessTokenEndpoint: 'https://github.com/login/oauth/access_token',
      redirectUrl: 'myapp://oauth/github',
      scope: 'read:user user:email',
      pkceEnabled: true,
    },
  },
});

Core flow examples

await SocialLogin.login({
  provider: 'google',
  options: { scopes: ['profile', 'email'] },
});

await SocialLogin.login({
  provider: 'oauth2',
  options: {
    providerId: 'github',
    scope: 'read:user user:email',
  },
});

Session checks

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

Auth codes and refresh

// For providers that support this mode
const authCodeResult = await SocialLogin.getAuthorizationCode({ provider: 'google' });
await SocialLogin.refresh({ provider: 'google', options: {} as never });

Advanced helpers

const jwt = await SocialLogin.decodeIdToken({
  idToken: 'eyJhbGciOi...',
});

const { date } = await SocialLogin.getAccessTokenExpirationDate({
  accessTokenExpirationDate: Date.now() + 3600 * 1000,
});

const expired = await SocialLogin.isAccessTokenExpired({
  accessTokenExpirationDate: Date.now() + 1000,
});

const active = await SocialLogin.isRefreshTokenAvailable({ refreshToken: 'a-token' });

Provider-specific notes

Google offline mode

google.mode: 'offline' returns serverAuthCode from login. In this mode logout, isLoggedIn, getAuthorizationCode, and refresh are not available.

Use serverAuthCode only as input to your backend token exchange. If you need to call SocialLogin.refresh() in the app, use google.mode: 'online' instead.

Apple

Set useProperTokenExchange: true for strict token handling and useBroadcastChannel: true for Android simplified setup.

OAuth2 web redirect flow

Use OAuth2LoginOptions.flow: 'redirect' for web flows that navigate away from the page.

Provider configuration in Capacitor

You can disable unused providers to reduce native binaries:

import type { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: 'com.example.app',
  appName: 'My App',
  webDir: 'dist',
  plugins: {
    SocialLogin: {
      providers: {
        google: true,
        facebook: true,
        apple: true,
        twitter: false,
      },
    },
  },
};
