[Vue.js] Activate router-link that has multi level nested routes with CRUD setup

I trying to setup deep nesting like below, and when kinda sure about we cannot use exact in router-link for nested routes.

<div id=”app”>
<nav class=”nav nav-main”>
<router-link exact to=”/“ class=”nav-link” activeClass=”active”>Dashboard</router-link>
<router-link to=”/projects” class=”nav-link” activeClass=”active”>Projects</router-link>
</nav>

<div class=”parent-content”>
<h4>Content for Parent goes here</h4>
</div>

<router-view>
<nav class=”nav nav-main”>
<router-link :to=”‘/projects/‘ + $route.params.projectId” class=”nav-link” activeClass=”active”>Deals</router-link>
<router-link :to=”‘/projects/‘ + $route.params.projectId + ‘/commitments/‘“ class=”nav-link” activeClass=”active”>Commitments</router-link>
</nav>
<router-view>
<div class=”child-content”>
<h4>Content for Child goes here</h4>
</div>
</router-view>
</router-view>
</div>

My Route:

routes: [
{
path: ‘/‘,
component: Dashboard
},
{
path: ‘/projects’,
component: Projects
},
{
path: ‘/projects/:id’,
name: ‘projects-detail’,
component: ProjectDetails,
children: [
// DEALS
{
path: ‘/projects/:projectId/deals’,
component: Deals
},
{
path: ‘/projects/:projectId/deals/:dealId/details’,
component: DealDetails
},
// COMMITMENTS
{
path: ‘/projects/:projectId/deals/:dealId/commitments/:commitmentId/edit’,
component: CommitmentEdit
}
]
}
]

With the above setup, I need to activate router-links, when the route is:
/projects/:projectId/deals/:dealId/details then activate Deals
/projects/:projectId/deals/:dealId/commitments/:commitmentId/edit then activate Commitments

Solution :

I think you have not another <router-view></router-view> inside ProjectDetails component add this and try.

Also remove /projects/:projectId from all child path as you have already in parent path path: ‘/projects/:id’,

So final you route would be

routes: [
{
path: ‘/‘,
component: Dashboard
},
{
path: ‘/projects’,
component: Projects
},
{
path: ‘/projects/:id’,
component: ProjectDetails,
children : [
// DEALS
{
path: ‘deals/:dealId/details’,//path will be /projects/:projectId/deals/:dealId/details
component: DealDetails
},
{
path: ‘deals’,.// path will be /projects/:projectId/deals
component: Deals
},
// COMMITMENTS
{
path: ‘/deals/:dealId/commitments/:commitmentId/edit/‘,
component: CommitmentEdit
}
]
}
]

Here is working fiddle : https://jsfiddle.net/chyLjpv0/16/

Read more about child path.

If you need not and component depended on parent dont make it as child use directly as root path like

routes: [
{
path: ‘/‘,
component: Dashboard
},
{
path: ‘/projects’,
component: Projects
},
{
path: ‘/projects/:id’,
component: ProjectDetails,
},
// DEALS
{
path: ‘/projects/:projectId/deals/:dealId/details’,
component: DealDetails
},
{
path: ‘/projects/:projectId/deals’,
component: Deals
},
// COMMITMENTS
{
path: ‘/projects/:projectId/deals/:dealId/commitments/:commitmentId/edit/‘,
component: CommitmentEdit
}
]

Working fiddle for this : https://jsfiddle.net/chyLjpv0/17/

Class router-link-exact-active is already working in this example : https://jsfiddle.net/chyLjpv0/18/ to display link as active

In the edit

Why you put <router-view> inside <router-view>. Outer is only working as it is being replaced and inner <router-view> is worthless. Use <router-view> in parent component for child component.

Also the inner <router-view> is not closed properly like </router-view>
