Hey @rarmatei, we currently don’t support custom “ignore build” commands. I believe the current command is basically a flag that’s sent- if there’s no flag, we don’t build. Correction: We do support custom “ignore build” commands!
No npm modules will be available at that point though. However, you may want to sign up for our Build Plugins beta and see if you can accomplish what you want that way:
Netlify Build Plugins extend the functionality of the Netlify Build process. You can install plugins made by others, or write your own.
Let us know if you go that route and if we can answer any other questions on this!
