Slack / Discord Bot (TypeScript, Express, Redis, PostgreSQL, Docker) overview

A chatbot platform serving both Slack and Discord workspaces through a unified TypeScript backend, handling slash commands, interactive modals, event subscriptions, and scheduled messages. Express routes incoming webhooks and verifies request signatures, while Redis queues outbound messages and caches conversation state for multi-turn interactions. PostgreSQL stores user preferences, command history, and analytics data. BullMQ processes background jobs like scheduled reminders and batch notifications. The bot supports rich message formatting, button interactions, and modal dialogs through a platform-abstraction layer. Docker containers deploy the complete system. The tradeoff is managing divergent APIs between Slack and Discord and handling rate limits gracefully, but a well-built bot dramatically improves team automation and developer experience within collaboration tools.
