Overview¶

OmniChat provides a unified interface for building messaging applications across multiple platforms. Write your message handling logic once and deploy it across Discord, Telegram, and WhatsApp.

Features¶

Core Provider Interface¶

type Provider interface {
    Name() string
    Connect(ctx context.Context) error
    Disconnect(ctx context.Context) error
    Send(ctx context.Context, chatID string, msg OutgoingMessage) error
    OnMessage(handler MessageHandler)
    OnEvent(handler EventHandler)
}

Message Router¶

The router manages multiple providers and routes messages using pattern matching:

router := provider.NewRouter(logger)
router.Register(discordProvider)
router.Register(telegramProvider)

// Route patterns
router.OnMessage(provider.All(), handler)           // All messages
router.OnMessage(provider.DMOnly(), handler)        // DMs only
router.OnMessage(provider.GroupOnly(), handler)     // Groups only
router.OnMessage(provider.FromProviders("discord"), handler)

Providers¶

Discord	discordgo	Guilds, DMs, threads, media

WhatsApp Session Persistence¶

WhatsApp sessions are persisted using SQLite with a pure Go driver (modernc.org/sqlite), requiring no CGO:

whatsapp.New(whatsapp.Config{
    DBPath: "whatsapp.db",
    QRCallback: func(qr string) {
        // Display QR code for scanning
    },
})
