📄️ Deployment on a VPS
Deploying to your own VPS with Coolify gives you more control and avoids the cold start limitations of free PaaS tiers. However, this document won't go too deep about how to set up a VPS + domain + Coolify instance itself.
📄️ Observability
Observability is about understanding what your application is doing in production without having to add print statements and redeploy. When something breaks at 3 AM, you need to trace requests across services, see error logs in context, and understand performance bottlenecks without guessing.
📄️ GitHub Dependabot and CodeQL
Your dependencies will get outdated. Your code will have security vulnerabilities you didn't know about. These aren't hypotheticals, they're certainties. The only question is whether you find out proactively or after something breaks.
