# Socialite (LINE Login) - LINE SDK for Laravel

> OAuth2 authentication with LINE Login using Laravel Socialite.

## Overview

This package provides a LINE Login driver using the standard `Socialite::extend()` approach. It works with the same API as any built-in Socialite provider.

Available drivers:

| Driver       | Description                                                                             |
| ------------ | --------------------------------------------------------------------------------------- |
| `line-login` | OAuth2 authentication via [LINE Login](https://developers.line.biz/en/docs/line-login/) |

<Info>
  For general Socialite usage, see the [Socialite guide](/en/socialite).

## Configuration

### .env

```dotenv theme={null}
LINE_LOGIN_CLIENT_ID=
LINE_LOGIN_CLIENT_SECRET=
LINE_LOGIN_REDIRECT=
```

## Basic usage

<Steps>
  <Step title="Define routes">
    Add redirect and callback routes to `routes/web.php`.

    ```php theme={null}
    use App\Http\Controllers\SocialiteController;

    Route::get('login', [SocialiteController::class, 'login']);
    Route::get('callback', [SocialiteController::class, 'callback']);
    ```
  </Step>

  <Step title="Create a controller">
    ```php theme={null}
    <?php

    namespace App\Http\Controllers;

    use App\Models\User;
    use Illuminate\Http\Request;
    use Laravel\Socialite\Facades\Socialite;

    class SocialiteController extends Controller
    {
        public function login()
        {
            return Socialite::driver('line-login')->redirect();
        }

        public function callback(Request $request)
        {
            if ($request->missing('code')) {
                return redirect('/login')->withErrors('Authentication was cancelled.');
            }

            /** @var \Laravel\Socialite\Two\User */
            $user = Socialite::driver('line-login')->user();

            $loginUser = User::updateOrCreate([
                'line_id' => $user->id,
            ], [
                'name'          => $user->nickname,
                'avatar'        => $user->avatar,
                'access_token'  => $user->token,
                'refresh_token' => $user->refreshToken,
            ]);

            auth()->login($loginUser, true);

            return redirect()->route('home');
        }
    }
    ```
  </Step>
</Steps>

## Optional parameters

Pass additional parameters with `with()`.

```php theme={null}
public function login()
{
    return Socialite::driver('line-login')->with([
        'prompt'     => 'consent',
        'bot_prompt' => 'normal',
    ])->redirect();
}
```

## Scopes

Specify the permissions you want with scopes.

```php theme={null}
public function login()
{
    return Socialite::driver('line-login')
                    ->setScopes(['profile', 'openid'])
                    ->redirect();
}
```
