Hi i'm facing a problem where i want to add new route dynamically
My route structure will look something like this
I'm using "vue-router": "^3.5.3"
const router = new VueRouter({
routes: [
{ path: '/user/:id', component: User, name:'User'
children: [
{
path: 'profile', component: Profile, name:'Profile'
children: [
{
path: 'about', component: About, name:'About'
children: [
{
path: 'details', component: Details, name: 'Details'
}
]
}
]
}
]
}
]
})
Now my intention is to add child route to Details
this is how my pseudo code looks like
findRouteWithName(routeObj,routeName)
{
// recursive find with any nested level
....
return foundRoute;
}
let routeObj = findRouteWithName(this.$router.options.routes,'Details');
routeObj.children.push(Route object{});
//this.$router.addRoutes([routeObj]) // this line creates problem as mentioned below in **problem:**
Note: if i'm doing like this https://stackoverflow.com/a/48833074/10054910 it is creating multiple nested routes in the url
Problem: page is becoming blank with direct push on children even route does not change in url. with this https://stackoverflow.com/a/48833074/10054910 approach route changes in url but append 2 times
Please help me thanks in advance !!

In my Vue 2.7.5 app (using Vue Router 3.5.4). I'm trying to map multiple URLs to the same component. Currently, I have a single route mapped to the component:
{
path: '/customer/:customerId',
component: CustomerOrders
}
My goal is to add an optional orderId parameter, such that if a URL like /customer/42/order/59 is accessed, then the same component is loaded, but the order with ID 59 is highlighted (the details of how the param is going to highlight the order are not important).
I tried changing the path to /customer/:customerId/orders/:orderId?, but this would no longer match any URLs of the form /customer/:customerId and would therefore be a breaking change.
My current solution is to use a child route:
{
path: '/customer/:customerId',
component: CustomerOrders,
children: [
{
path: 'order/:orderId',
component: CustomerOrders
}
]
}
This work as the CustomerOrders component is loaded by paths matching either /customer/:customerId or /customer/:customerId/order/:orderId, but it seems like a slightly convoluted approach and I'm not sure it's an appropriate use of child routes.
Is there a better solution?
The easiest way is to register the same component for both routes:
{
path: '/customer/:customerId',
name: 'CustomerOrders',
component: () => import( '../views/CustomerOrders.vue'),
},
{
path: '/customer/:customerId/order/:orderId',
name: 'CustomerOrders',
component: () => import( '../views/CustomerOrders.vue'),
},
An exact solution that you are looking for is parsing params manually:
{
path: '/customer/:param+',
name: 'CustomerOrders',
component: () => import( '../views/CustomerOrders.vue'),
props: router => {
const params = router.params;
const split = params.param.split('/');
params.customerId = split[0];
if (split.length > 2) {
params.orderId = split[2];
}
},
},
Here the :params+ ensures that a customerId and the rest of the route get caught. On the other hand, using :params* catches the /customer route without even a customerId.
CAUTION This approach also /customers/42/...everything...
The vue3 solution is solved here.
EDIT: the following approach cannot catch orderId
Using an alias improves reusability and reduces rendering time but comes with a price of capturing params-change in a watch handler.
{
path: '/customer/:customerId',
name: 'CustomerOrders',
alias: '/customer/:customerId/order/:orderId',
component: () => import( '../views/CustomerOrders.vue'),
},
In this case, your component doesn't get rebuilt by changing routes and also onMount or beforeCreate hooks don't get called either. To catch params-change add a proper watch:
export default {
name: 'CustomerOrders',
watch: {
'$route.params'() {
console.log('params changed. Extract params manually and reload');
},
},
};
This issue is addressed here.
I'm using Vue Router with Vue 3 and am trying to add a catch-all route to redirect the user if they try and access an invalid URL. When I try and use the wildcard (*), i get the following error logged to the console:
Uncaught Error: A non-empty path must start with "/"
at tokenizePath (vue-router.esm.js?8c4f:975)
at createRouteRecordMatcher (vue-router.esm.js?8c4f:1106)
at addRoute (vue-router.esm.js?8c4f:1190)
at eval (vue-router.esm.js?8c4f:1335)
at Array.forEach (<anonymous>)

at eval (index.js?a18c:26)
at Module../src/router/index.js (app.js:1402)
at __webpack_require__ (app.js:854)
I'm assuming this is because I don't prepend the path containing the asterisk with a '/', but if I do this then the catch all doesn't work. Here are my routes:
imports...
const routes = [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/user',
name: 'User',
// route level code-splitting
// this generates a separate chunk (user.[hash].js) for this route
// which is lazy-loaded when the route is visited.
component: () => import(/* webpackChunkName: "user" */ '../views/user/User.vue'),
children: [{path: '', component: UserStart}, {path: ':id', component: UserDetail}, {path: ':id/edit', component: UserEdit, name: 'userEdit'}]
},
{path: '/redirect-me', redirect: '/user'},
{path: '*', redirect: '/'}
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
The wildcard route is the last object in the routes array. Does anyone know what I'm doing wrong?
Catch all routes (/*) must now be defined using a parameter with a custom regex: /:catchAll(.*)
For example:
{
// path: "*",
path: "/:catchAll(.*)",
name: "NotFound",
component: PageNotFound,
meta: {
requiresAuth: false
}
}
Personally, for Vue 2's * (star or catch all) routes in Vue 3 I use:
{
path: '/:pathMatch(.*)*', <== THIS
name: 'not-found',
component: NotFound
}
Catch all routes (*, /*) must now be defined using a parameter with a custom regex:
The parameter name can be whatever you want like catchAll, pathMatch, noPage etc
{
path: '/:pathMatch(.*)*', //will match everything and put it under `$route.params.pathMatch`
name: 'not-found',
component: NotFound
}
{
path: '/user-:afterUser(.*)',// will match anything starting with `/user-` and put it under `$route.params.afterUser`
component: UserGeneric
}
/:pathMatch(.*)*
The last * it is necessary if you plan on directly navigating to the not-found route using its name.
If you omit it the / character in params, it will be encoded when resolving or pushing.
For example if you use path: /:pathMatch(.*) (note: without the last asterisk) and you go to /user/not-found (a page that doesn't exists) the this.$route.params.pathMatch will be a string => 'user/not-found'
// bad example if using named routes:
router.resolve({
name: 'bad-not-found',
params: { pathMatch: 'not/found' },
}).href // '/not%2Ffound'
Instead, if you use path: /:pathMatch(.*)* (note: with asterisk) this.$route.params.pathMatch will be an array ['user', 'not-found']
// good example:
router.resolve({
name: 'not-found',
params: { pathMatch: ['not', 'found'] },
}).href // '/not/found'

I'm setting up a website which will contain groups, these groups can have sub-groups and these sub-groups can have sub-groups and so on...
Is this in any way possible?
Ofcourse making the path of a route like: /groups/:slug/:slug does not work since it contains duplicate params.
What I was thinking of was using the star pattern as child route, this child route will redirect the user back to the parent route with the slug and a sub-slug, then the next action will be to act on the sub-slug if it exists. But maybe someone has a better solution to this?
const groupRoute = {
path: `/groups/:slug`,
name: 'group',
component: Group,
children: [
{
path: '',
component: GroupsHome
},
{
path: '/subgroups',
component: SubGroups
},
{
path: '*',
beforeEnter(to, from, next) {
next({
name: 'group',
params: {
slug: to.params.slug,
subSlug: to.params.pathMatch
}
})
}
},
]
}
Here is a basic example:
Nested navigation with similar structure for nested objects. The trick here is to use a different param name for inner routes.
I have the following structure in vue.js ,using vue-router.
routes: [
{
path: '/domains',
component: ListOfDomains
},
{
path: '/domain/:domainName',
component: Domain,
children: [{
// Photos Tab content will be rendered inside domain's <router-view>
// when /domain/:id/photos is matched
path: 'posts',
name: 'posts',
component: PostsTabContent
},
{
path: 'photos',
name: 'photos',
component:PhotosTabContent
}
]
}
]
In my Domain component I use a watcher to fetch domain related data from server such as:
"$route": function(to, from) {
console.log("watcher triggered");
//do update only if domain has changed
//do something , ajax request , update store etc
}
This seems to work fine, but my problem is that I only want to do my updates if the url changes from, say, domain/domain23/posts to domain/domain45/posts and not when it changes from domain/domain23/posts to domain/domain23/photos.
How can I watch only that level in the route for changes?
I am building an app with the following route settings.
export default new Router({
routes: [
{
path: '/login',
name: 'Login',
component: Login
},
{
path: '/home',
name: 'Dashboard',
component: Dashboard,
beforeEnter(to, from, next) {
if (!store.getters.isLoggedIn) {
next('/login');
} else {
next();
}
}
},
{
path: '/',
redirect: '/home'
}
]
});
I also set query parameters based on some select boxes I have by using $router.push say as follows.
this.$router.replace({
query: {
scope: this.$store.getters.filterScope
}
});
Problems I have
Reloading the page removes the query params from the URL.
Updating one query parameter removes the other one I had. Example - updating scope using the above method removes the dateRange parameter I already had.
I am using Vuex too so is there any way I can manage these query params using the store?
If you store your parameters in vuex and you don't use vuex-persistedstate, when you refresh the page state will be removed.
So, my suggestion for you:
your-awesome-site.com/dashboard?first=hello&second=hi
In your Dashboard component, you can do like this
mounted () {
console.log(this.$route.params)
// Update vuex state filterScope
}
So you will retrieve your parameters from url and save it in vuex.
Also you can solve your second issue using this.$route.params
