Ask HN: Tools for building high performance REST API in 2019

Could you be a little more specific about your requirements / constraints? Otherwise, you aren't asking anything here that couldn't be answered with a trivial Google search.

Sorry, I have edited my question. I'm planning to build something from scratch. Setup my own server, have an API gateway(similar to AWS) and use PostGreSQL. Thanks.

Lumen (PHP, micro-framework by Laravel): https://lumen.laravel.com/

I would use Golang and Postgresql. Possibly add the Chi library for routing and may be GORM for ORM (if you don't want to deal with more direct SQL).

Give golang, gorm, and fresh a shot

Sorry to ask, but what's fresh?

Bare metal or VM - Loopback.io PaaS - AWS Lambda, Firebase Your own cluster - Kubernetes

Bare Metal. I was thinking on setting up my own server.

It might help to mention what skills you already have, or languages you already know?

Java, Python and Nodejs. But I'm not fixated to use these. I can learn new tech if its better.
