Publish js/php files to modify and regenerate SPA {development and production workflow}

[KishanFX]

for those who are working with large apps where the blog is just a small part.

1. want different or consistent UI
2. custom middleware behavior.
3. custom auth.
4. more relationships with other models.
5. other various customization.
   is there any way to publish editable files to achieve the above requirements?
   also for the VUE part, a workflow to edit files and watch with Laravel-mix and generate minified files.

it may sound dumb for those who are regularly working with Javascript SPA, custom composer package, or module bundler.
but it will be helpful to many users.
try to provide any helpful way to do this if not present already.
any other custom setup, blog, or video.
