How to exhange a full route? Router-link exchanges only the last part of the route - vue.js

Question

I am new to vue and vue router and am using Vue router in history mode. The app contains a menu which is dynamically loaded
<router-link
tag="li"
class="link"
v-for="item in menu"
v-bind:key="item.id"
:to="item.slug"
:exact="item.slug === '/' ? true : false">{{ item.content }}
</router-link>
It works well as long as I stay in the parent routes like http://localhost:8080/posts As soon as I navigate a level deeper, e.g. to a post with the id 8 http://localhost:8080/posts/8 with a routerlink inside the Template
<router-link
tag="h2"
class="link"
:to="{ name: 'post', params: { id: post.id }}">
{{ post.title.rendered }}
</router-link>
it works in one way, but doesnt go back to the parent route when I click the main navigation links. Instead just adds the link of the main menu to the end of the route, e.g. instead of http://localhost:8080/posts
http://localhost:8080/posts/posts
The router
const router = new Router({
mode: 'history',
base: '',
routes: [
{ path: '/', name: 'home', component: HomePage },
{ path: '/posts', name: 'posts', component: PostsPage },
{ path: '/posts/:id', name: 'post', component: SinglePost },
{ path: '/projects', name: 'projects', component: ProjectsPage },
{ path: '/projects/:id', name: 'project', component: ProjectPage },
{ path: '/:page', name: 'page', component: SinglePage },
{ path: "*", redirect: '/' },
],
// etc..
});
I guess I am making a common mistake, but I can´t find a solution. Any help appreciated.

You can use absolute paths. Instead of
<router-link
tag="h2"
class="link"
:to="{ name: 'post', params: { id: post.id }}">
{{ post.title.rendered }}
</router-link>
use
<router-link
tag="h2"
class="link"
:to="{ name: '/post', params: { id: post.id }}">
{{ post.title.rendered }}
</router-link>
The change is /post vs post in router-link's :to attribute.
You could and probably should use nested routes and components for posts posts/:id, but this a little more work and you my not need it at the moment. More on nested routes here.
