I’m not sure I understand your question. Typically, during development, you run npm run dev
This starts the development server and keeps running to provide hot module replacement (HMR) and real-time updates as you make changes.
When you're ready to deploy your application to production, you run npm run build
This generates optimized production assets. Unlike npm run dev, which runs continuously, npm run build is a one-time command that outputs the final files for production use.
Let's say my Vue component is a chat icon that floats on the page
Clicking on it opens a window that allows me to chat
This can be reused in project A, B, C, D
But it has only 1 look and feel, how do I give CSS control of the chat icon to each of the projects without each project having to run npm run build or dev
Imagine a scenario where I don't want to give them my Vue source code
