Build a Feedback Channel That Does Not Become Another Abandoned Inbox

Short summary

A practical tutorial for building an operational feedback system using TypeScript, Express, and PostgreSQL with a transactional outbox pattern. It models a feedback lifecycle (captured → new → acknowledged → planned/resolved/closed) and emphasizes three critical properties: an owner, a next-action timestamp, and a reply path. The article includes full SQL schema definitions and architectural guidance on keeping PostgreSQL as the source of truth while treating chat and email as delivery surfaces only.

• •Feedback systems need ownership, next-action timestamps, and reply paths to avoid becoming abandoned inboxes
• •Uses PostgreSQL as source of truth with a transactional outbox pattern for reliable notification delivery
• •Includes complete schema for feedback, feedback_event, and feedback_outbox tables with indexing strategies
