I see some worrisome coding patterns here: https://github.com/TahaSh/vue-forum-app/blob/master/src/view...

        <base-button
          v-if="isLoggedIn && currentUser.can('own_topics:write')"
          class="new-topic-button"
          :to="{ name: 'CreateTopic' }"

There is logic embedded in the view. Does this get compile-time checked (assuming you used a compiler such as TypeScript)? In my opinion this is the weak-point of Vue. It is possible to use JSX in Vue. But it is also possible to use non-compile-time-checked expressions. In React you only have compile-time-checkable syntax. That's better because when a code is written using React (by someone other than you) you immediately have some reassurance that some poor coding patterns are excluded.
