README

A Flarum extension that lets forum users connect their LINE account and receive forum notifications (mentions, replies, likes, subscriptions) via LINE push messages.

Features

• 🎨 Custom branding — rich Flex Message cards with the forum's color scheme
• ⚙️ Admin settings — Channel ID, Channel Secret, Messaging API Token configurable from Flarum Admin
• 🛡️ Auto-cleanup — if a user blocks the LINE bot, their LINE data is automatically cleared
• 🔗 Webhook endpoint — handles LINE unfollow/block events

Architecture

Notification Flow

Flarum notification event
    → Extend\Notification()->type(Blueprint, ['line'])
    → LineNotificationDriver::send($blueprint, $users)
    → FlexMessageFormatter::format($blueprint)
    → LineApiClient::pushMessage($lineUserId, $messages, $token)
    → LINE Messaging API
    → User's LINE app

OAuth Flow

User clicks "Connect LINE" in Settings
    → GET /api/line/connect
    → ConnectController: build authorize URL with signed state
    → Redirect to LINE OAuth
    → User grants consent
    → LINE redirects to GET /api/line/callback?code=...&state=...
    → CallbackController: verify state, exchange code, fetch profile
    → Write line_user_id, line_display_name, line_linked_at to user
    → Redirect to /settings?line_linked=1
