Umbraco cloud 13 npm scss build

Is it possible to run a npm build on umbraco cloud v.13.
We have a simple uSkinned umbraco solution, but want to expand with some scss in the near future.

Do we need our own build service to do this, or is it possible without?

As far as I know, you’re going to have to look into their CICD Api

I’ve used it on a few projects - can be a bit tricky to setup, but once you are up and running, you can build your frontend in your own pipeline.

Umbraco Cloud does not let you run a npm build as part of their pipeline.

As well as Umbraco CI/CD Flow, I use an alternative CI/CDprocess that works well for me.

If you want to keep it super-simple, an option that can work well is to have a separate dedicated frontend build that just handles the frontend assets and deploys them to different hosting altogether on a subdomain e.g. assets.example.com
