What are all the things to consider and account for when deploying a Node.js app and post-deployment?

I am working on a web application in Node.js for a department at my university. I am also working with a worker who is helping me in deploying the app on the school server and open the ports to have the application to everyone.This is my first time deploying a Node.js app and would like to have the application and have no errors, crashes and other possible problems, for years to come. I have a feeling the application could crash or run into errors for things I might have missed or forgot to consider. For example what if I have to upgrade a dependency or module in the future that the application depends on to work? How should I handle that?What are all the things I should make sure are in-place and working fine during and post-deployment, (sort of like a checklist) to make sure my application will be working fine for years to come?
