Seeking Advice: Best Practices for Deploying Node.js project on Railway.app

Hi everyone!
​I’m currently working on a website project and I’m looking to deploy it using Railway. While I love the platform's interface, I’m hitting a few snags with the initial configuration and would appreciate some guidance from anyone who has experience with their environment.
​Specifically, I’m looking for help with:
​Build Commands: Ensuring my environment variables and start commands are correctly recognized during the deployment phase.
​Database Provisioning: Best practices for connecting a database (PostgreSQL/Redis) within a Railway project.
THANK YOU
