Hi Miguel,
You are right, PASE is definitely one of the prerequisites and a few odd things more below.
Quite simple to install nowadays, just follow the steps here first :

Then for NodeJS:(not sure about Newman though, that one doesn't seem officially supported? )
https://ibmi-oss-docs.readthedocs.io/en/latest/nodejs/README.html
Note: just remember setting the paths accordingly, and if you need to "secure" the instances, have a look at "CHROOT"-ing the environment to keep things totally seperate from one another.
If you do need official support for bugs and fixes, I can recommend these two companies:
https://www.seidengroup.com/
https://www.perforce.com/products/openlogic
If you need more help, give me a PM, and I can assist you in setting the environment up quickly.
