Dev environment for vuejs for beginners


I want to learn to use vuejs in nextcloud for developing a new app.
My research result is, that it is the best way to use a js framework as new standard for nc apps, isn’t it?

In the sample app it is the “big solution” with pre-compiling the js code.
My try to use vuejs directly for learning intention is forbidden by the security settings.

Is there a useful way to relax the security setting (only for learning and developing) or do I have always to pre-compile?
If so is there a tutorial how to start with vuejs in nc with description how to set up a useful dev environment?

Thanks again for helping.
