[Vuejs]-Eslint configured the same for 2 folders, but linting differently

Your server side code uses require whereas your client side code does it using import. So yeah, you cannot actually compare the validity of the same amongst both of them.

If you have the look at the documentation here ( which you may trace from the link above the error snippet you shared ), you may realize this : It is not the airbnb style guide but the eslint default rule for ASI ( aka automatic semicolon insertion) . You may wish to remove the influence of the same from your code.

Addendum : As Fabio Antunes just commented, you may wish to remove the eslint-standard from your package.json. Let us know if that helps.
