go-notification

Four chat platforms for internal notifications — Slack, Telegram, Discord, Microsoft Teams.

The chat channel family is built for team-internal notifications — deploys, alerts, build status, ops. All four drivers are free to use (they only cost you the time to set up bots/webhooks).

Driver Comparison

Driver	Setup Complexity	Best For	Note
Slack	Low	Engineering teams, SaaS dashboards	Incoming Webhook or Bot token.
Telegram	Very low	Personal alerts, small teams, bots	No workspace concept — just chat IDs.
Discord	Low	Gaming, community, OSS projects	Webhook URL per channel.
MS Teams	Medium	Enterprise orgs already on Microsoft 365	Incoming Webhook or Power Automate flow.

Routing

For per-recipient routing, return the chat/user/channel ID from RouteNotificationFor(channel):

main.go

func (u User) RouteNotificationFor(channel string) any {
    switch channel {
    case "slack":    return u.SlackUserID         // U01ABCD...
    case "telegram": return u.TelegramChatID      // 123456789
    case "discord":  return u.DiscordChannelID    // for bot-based Discord
    case "teams":    return u.TeamsChannelWebhook // URL-based
    }
    return nil
}

For shared-channel notifications (everyone sees the same #alerts channel), a single webhook URL in the config is enough — no per-user routing needed.

Multi-workspace pattern

Multiple Slack workspaces, multiple Teams tenants, multiple Discord servers — register each under its own channel name:

main.go

notifier.RegisterChannel("slack-eng",    slack.NewWebhook(slack.WebhookConfig{URL: engURL}))
notifier.RegisterChannel("slack-ops",    slack.NewWebhook(slack.WebhookConfig{URL: opsURL}))
notifier.RegisterChannel("slack-sales",  slack.NewWebhook(slack.WebhookConfig{URL: salesURL}))

Then the notification's Via() picks which workspace gets the message.

When not to use chat

Customer-facing notifications — use email/WhatsApp/SMS for users, chat for your team.
High-volume alerts — Slack/Teams will rate-limit you. For firehose logging, send to the database channel and let humans query, not chat noise.
Sensitive data — chat platforms log everything, even deleted messages (on paid tiers with admin audit).
