vue-router won't render template on nested route - javascript

So I have a route like this:
const routes = [{
path: '/',
component: Home,
children: [
{
path: "/health"
children: [
{
path: 'overview'
component: Overview
},
{
path: 'blood',
component: Blood
}
]
}
]
}]
and in the Home component I have something like this:
<template>
<div id="home">
<router-view></router-view>
</div>
</template>
But when I navigate to the /health/overview and /health/blood routes, the templates corresponding to the components won't render. I checked the apps $route objects, they correctly detect the routes and the components. Just the template won't render. I also have a <router-view> in my App.vue if that helps.
Is it not possible to have multi nested routes? Or am I missing something?

The health route should be like this:
{
path: 'health', // not '/health'
component: Health, // this can just be a dummy component with a <router-view/>
children: [...],
},
If you don't need the Health component at all for any reason (i.e. you don't have any shared functionality or template across each child), you can just remove the health route completely and replace it with this instead:
{
path: 'health/overview',
component: Overview,
},
{
path: 'health/blood',
component: Blood,
},

Angular 9 : Children routing inside lazy loaded component not working

I have app component in which i lazy load create-new-module with component profilecomponent. now in profile component i hit router.navigate and trying to load another children detail in place of profile but its not working also no error in console.
please help
// App component route
const routes: Routes = [
{
path: 'create-new-emp',
loadChildren: () => import('./create-new-emp/create-new-emp.module').then(c => c.CreateNewEmpModule),
},
{ path: '', redirectTo: 'create-new-emp', pathMatch: 'full'},
{ path: '**', redirectTo: 'create-new-emp'}
];
// Emp Module Route
const routes: Routes = [
{ path: '', component: ContainerComponent,
children: [
{ path: '', component: ProfileComponent, outlet: 'form'},
{ path: 'profile', component: ProfileComponent, outlet: 'form'},
{ path: 'detail', component: DetailComponent, outlet: 'form' }] }
];
// Trying to hit below link but not working
this.router.navigate(['detail'])
<app-component>
<router-outlet>
<container-component>
<profile-component></profile-component>
</container-component>
</router-outlet>
</app-component>
Complicated with only these information to help. But is the way angular navigates amount components/pages. I think what you are trying to do is navigate between components (according your router.ts). If you want to navigate, you only need router-outlet in your html code and not use component tag in the HTML code.
Change this:
<app-component>
<router-outlet>
<container-component>
<profile-component></profile-component>
</container-component>
</router-outlet>
</app-component>
To this:
<app-component>
<router-outlet>
</router-outlet>
</app-component>
Then, into ContainerComponent.html you need to repeat to navigate to details o profile because these are child routes.
<router-outlet></router-outlet>
That will give you more information about what you need.
Its hard to say with this info, but may... you should define de router outlet name
<router-outlet name="form"></router-outlet>
Hope it's help.

Named router outlet doesn't render template in lazy loaded route

I have a problem with my angular 8 app, not rendering into a named router-outlet.
The routes are:
routes.module:
const routes: Routes = [
...
{
path: 'settings', loadChildren: './settings/settings.module#SettingsModule', canActivate
},
]
settings.module
RouterModule.forChild([
{
path: '', component: SettingsComponent
},
{
path: 'profile', component: ProfileComponent, outlet: 'settings_o'
},
{
path: 'users', component: UsersComponent, outlet: 'settings_o'
}
])
settings.component.html
<nav mat-tab-nav-bar color="primary" class="bg-whitesmoke primary">
<span mat-tab-link
*ngFor="let link of navLinks"
[routerLink]="[{outlets: {settings_o: [link.link]}}]"
routerLinkActive #rla="routerLinkActive"
[active]="rla.isActive">
{{link.label}}
</span>
</nav>
<router-outlet name="settings_o"></router-outlet>
When I click a link, the url in the address bar changes (e.g. to http://localhost:4200/settings/(settings_o:profile)), but no content is rendered to settings_o, nor do the components get loaded. There is no error in the console.
link.link is, for example simply profile like in settings.module's routes.
What do I need to change?
This is a known bug which has been discussed a lot: https://github.com/angular/angular/issues/10981
As far as I know it hasn't been solved completely but there are workarounds: https://github.com/angular/angular/issues/10981#issuecomment-454425220
You should give the lazy loaded module a default route and define the child routes for the components that you would like to open in the named outlet, for example:
RouterModule.forChild([
{
path: "default",
component: SettingsComponent,
children: [
{ path: "profile", component: ProfileComponent,outlet: "settings_o" },
{ path: "users", component: UsersComponent, outlet: "settings_o" }
]
}
]);
Of course you have to change the navigation to the SettingsComponent accordingly: routerLink='/settings/default'
I made a Stackblitz which is not an exact copy of your code but which shows how it can be solved: https://stackblitz.com/edit/angular-nctjpv
By the way, in your original solution, if you placed the named router outlet in the root component, I think it would display the child component but in the wrong place.

Angular 4 load child route in root outlet

I have a standard admin layout, where all main tabs are lazy loaded modules with separate state management. This is all wrapped in admin component with sidebar and router-outlet. One of my lazy-loaded admin tabs has a special component, which is supposed to open a full-screen preview of a product, occupying admin sidebar and navbar with it's own content.
My app router looks something like this:
export const appRoutes: Routes = [
/// ... some routes
{ path: 'admin', component: AdminComponent, canActivate: [SignedInGuard], children: [
/// ... some admin child routes
{ path: 'scrapers', loadChildren: '../scrapers/scrapers.module#ScrapersModule'}
/// ... some admin child routes
]}
/// ... some routes
]
And my scrapers module routes look like this:
export const scrapersRoutes: Routes = [
{ path: '', component: ScrapersListComponent },
{ path: 'single/:version', component: SingleScraperComponent, children: [
{ path: '', redirectTo: 'statistics', pathMatch: 'full' },
{ path: 'statistics', component: ScraperStatisticComponent },
{ path: 'targets', component: ScraperTargetsComponent },
]},
{ path: 'compare', component: CompareScrapersComponent },
{ path: 'preview', component: ScrapersPreviewComponent }
];
My goal is to open preview route of the scrapers module on the same outlet as admin.
My ideas for now:
a) overkill with html/css (very bad idea)
b) create a separate module for preview. Sounds resolute, but it hardly depends on scrapers lazy-loaded state, so I would not do this
c) load preview in a higher hierarchy outlet. If there is a valid way to do it, I would choose this.
Please, share your thoughts. Thanks!

Multiple routers with vue

I am running a PHP application where I will need some pages to have the ability to completely swap out views. I need a fully fledged router because I need to take advantage of the history mode API.
It is easy enough to do something like this with the Vue router:
const router = new VueRouter({
routes: [
{ path: '/', component: DefaultView },
{ path: '/map', component: MapView }
]
});
Within PHP I simply load the router like so and pass the PHP generated backend data to both views:
<router-view data="<?= $data ?>"></router-view>
This works for one page, but what if I want to have another page with a completely different set of routes? The router needs to be made aware what page it is on in order to differentiate between different sets of routes.
I either would need to check the URL of pass in a prop like I am already doing with my data. I am unsure how to read the prop data from the router though.
What would be a good way to deal with this?
you simply make two named router-views
and pass different data to these router-views.
<router-view class="view one"></router-view> //default
<router-view class="view two" name="a"></router-view>
<router-view class="view three" name="b"></router-view>
routes: [
{
path: '/',
components: {
default: Foo,
a: Bar,
b: Baz
}
},
{
path: '/map',
components: {
default: Foo2,
a: Bar2,
b: Baz2
}
}
]
Or use nested route views //children
routes: [
{ path: '/page1', component: page1,
children: [
{
path: 'route1',
component: route1
},
{
path: 'route2',
component: route2
}
]
},
{ path: '/page2', component: page2, ... }
]

How to use component-nesting with vue-router?

I'm pretty new to Vue and I just can't find a good way how to use nested components alongside with vue-router.
What I have so far (some not-important code omitted):
index.html
<body>
<div id="app">
<router-view></router-view>
</div>
app.js
const router = new VueRouter({
routes: [{ path: '/login', component: Login }]
})
const app = new Vue({
router,
}).$mount('#app')
components/Login.vue
<template>
<h1>Please log in</h1>
</template>
This works perfectly well - I navigate to /login and it shows me the message in h1 tag. If I create more components, like Register or ResetPassword and add them to the router, it still works well. But the problem is that there is some repeating code in those components (for example, I want all the auth-related pages to have blue background) so I'd like to somehow create a "parent" component, that would define stuff that is same for all the "children" components. Something like:
Auth component (makes the page-background blue)
-> Login component (shows the login form)
-> Register component (shows the registration form)
I know I can do this through route's "children":
const router = new VueRouter({
routes: [
{ path: '/', component: Auth, children: [
{ path: '/login', component: Login }
{ path: '/register', component: Register }
]}
]
})
But with this configuration, there is the main route path: '/', which is completely wrong - I don't want it here - I don't want the Auth component to be used "standalone" - I want it just as a "wrapper" for the nested components.
What is the best way to solve this problem?
The way I've solved this issue is to use a base path redirect.
{ path: '', redirect: '/to/path' },
in your case it would be
const router = new VueRouter({
routes: [
{
path: '/',
component: Auth,
children: [
{ path: '', redirect: '/login' },
{ path: '/login', component: Login },
{ path: '/register', component: Register }
]
}
]
})
This ensures that
