There’s no command line because there’s no server. Neocities is “just hosting”. They have site-wide TLS certificates, it’s https only. In my opinion, it’s best to avoid running your own servers unless you really need to - it’s too hard to do well unless you actually want to eventually learn everything about running servers. Personally, I’ve made a conscious choice to be a programmer and not a server admin - as much as possible, I don’t want to care how it works. Once I’ve written the code, and it works, I want it to just keep working (and if it doesn’t, I want it to be someone else’s job to fix it).
I have my main site deployed to Netlify, which is what I’d really recommend to anyone interested in deploying serious static sites. For hosting the node projects, I’ve had no problems with Heroku and mLab, which both have a free tier. If you just need a virtual box, you can get 12 months of a single EC2 instance for free from AWS with a new account - you also get lots of free credits to play with their other services such as databases, the load balancer (I think you can have them manage TLS for you and have it terminate at the balancer, but I haven’t tried it yet) and their lambda ‘serverless’ framework.
