From Wordpress to Directus, but on what server/domain?

I have followed some tutorials, I have installed node.js + npm + created the database for directus in the subdomain, but while installing Directus I got some deprecated errors. Google AI mentions that the node.js version should be an active LTS, and I thought that installing the latest 22 version would be the best option. What am I doing wrong?

I kept going and tried “npx directus init” command, but I got a “out of memory: cannot allocate Wasm memory” error

Hey, I highly recommend using the Docker method.

I'm now kind of stuck because my client wouldn't like to purchase a new server (in case I'd use Docker) or upgrade the existing one that needs more memory (in case I'd go for the Node.js path). :-(
