@wamweaaa @your_javaguy I wouldn't call it overkill. NATS and RabbitMQ are lightweight and simple. If your MVP needs async processing, retries, or scalability, a message broker can be the simpler choice.

@your_javaguy Nope. Just a postgres table and a background worker. A message broker would be overkill for MVP.

Notification system working based on outbox pattern. If my email provider fails to send the email, a NodeJS worker checks for the event and retries it. After 5 failed retries, the event is labelled as FAILED. So the admin dashboard can easily see failing operations.

Currently implementing outbox pattern in my platform. When a user buys a digital poduct, we have to do like 3 ops at the same time. Send a receipt , send the digital product, update the db. An outbox event ensures we can verify these actions are actually taken and complete.

If you're building systems where performance, reliability, and scalability matter, languages like Go, Rust, Java, C#, and Dart are excellent choices. They offer predictable performance, strong tooling. But remember: security comes from good engineering—not just the language. 🚀

Your architecture probably just needs RabbitMQ, don't rush to Kafka until you understand the core use cases.

hot take: using .env files for secrets is wrong and we should move away from this.

There are things in software engineering that can only be learned from experience. You will not find them in textbooks, documentation or specifications. Senior engineers won't know to teach them to you because it's just an obvious habit for them. Practice, practice, practice
