I use Go, Vue.js, Postgres, NATS, Redis, Keel, and deploy everything Kubernetes.

So far I am super happy with the stack, runs cheaply and requires pretty much no maintenance. Just tag a release on GitHub, Google Cloud Builder builds the image, Keel updates deployments and in a few seconds I have updated production with zero downtime.

While some people are happy with their copy/paste binaries/code to remote servers, I think a good pipeline to release and run your workloads makes working on side projects a lot more pleasure where you can focus on code and features. It also provides you with a valuable experience that can make you more money than the side project itself :)
