question: as this change is related to angular guide, is that a relevant one for this PR?

Also why to favor npm install over npm ci (as it's also what's used below in the vuejs/develop.md)? npm ci will respect package-lock.json that is, from my perspective, best practice.

Hello, @eunomie.

Yep, the change is relevant to keep all the docs I created consistent.

I personally prefer npm ci for clean installs, but since we’re dealing with developing Vue.js inside Docker here, npm install can be better to allow installing new dependencies on the fly during development.

Hi @kristiyan-velkov, great guide! I was wondering if there’s an example app repository that goes along with it? Usually, Docker guides come with something to clone and run — like in https://docs.docker.com/guides/tensorflowjs/ or https://docs.docker.com/guides/language-translation/ from the AI section provided by Harsh. Would be great to try it out hands-on! 🙂
