I'm quite new to this VueJS things. And this is my first App creating a SPA with separated server-side app. I faced the problem right before deploying my app on a shared hosting. Simply, when i run "npm run build", it return with an error in which i don't even know the cause. Here is the error i faced.
Please help me resolve this issues, i know there are jquery errors, but i think those are not the problems
You have es-lint checker. It checks unused vars so you have unused variables inside these listed components like from and to. You should remove these variable from your components.
Those errors come from your linter (probably eslint) which is a tool designed to ensure consistence and code quality : in your case it mainly complains about declared variables that are not used anywhere else in your code and $ being undefined (I guess you're trying to use jquery which you should not be doing in a vue project anyway)
On the images you posted you have all necessary infos : the title of each block tells you in which file the error is (for example App.vue in the first image) and then you have line/column to locate precisely where you need to adjust :)
Note that you can configure your linter (what should be error/warning/skipped out) overwriting (or creating if it doesn't exist) a config file at the root of your project (if you use eslint for example, you can create a .eslintrc file). See the config part of the official doc
