I'm using VueJS 2.3.3 and coffescript and I'm trying to pass a prop to a component from the router, but I'm having no success. Code is not mine, so I'm having some trouble figuring out what am I doing wrong. Here's my router:
App = require './views/App'
Shared = {
header: require('./views/shared/header'),
global_loader: require('./views/shared/global_loader.vue')
}
view = (view_name) ->
require("./views/#{view_name}")
componentize = (view_name, options = {}) ->
options.include_header ?= true
component = options.component || {}
component.app ?= view(view_name)
component.header = Shared.header if options.include_header
component
exports.routes = [
{
path: '/',
component: App
children: [
{
path: '/component',
components: componentize('path/to/component'),
props: { has_groups: true }
},
...
]
}
...
}
Here's my App.vue code:
<template lang="pug">
#app-wrapper
transition(name="fade")
router-view(name="global_loader")
#header-wrapper
router-view(name="header")
#current-view-wrapper.container
transition(name="enter")
router-view(name="app")
</template>
On my component, I'm receiving the prop as usual:
props:
has_groups:
default: false
Everything works fine, except that has_groups doesn't receive the correct prop value from the router. It doesn't change to true.
Can anyone help me finding out what I'm missing?
I found the solution. As I'm using named routes, I have to configure the props like:
props:
global_loader: false
header: false
app: (route) -> ({ has_groups: true })

I'm having trouble understanding how to get a computed property all the way out through the router to my template. Here's a basic idea of what I'm doing:
const Home = {
template: '<router-link to="/level/1">Level 1</router-link>'
}
const Level = {
template: '<template>|{{ id }}|{{ message }}|</template>',
props: ['id','message']
}
const router = new VueRouter({
routes: [
{ path: '/', component: Home, props: true },
{ path: '/level/:id', component: Level, props: true }
]
})
const vm = new Vue({
el: '#app',
router,
template: '<router-view></router-view>',
computed: {
message() {
return 'HELLO';
}
}
})
When I click the "Level 1" link, the result I expect to see is:
|1|HELLO|
The result I actually see is:
|1||
The final usage will be a bit more functional than this, but hopefully that's enough to expose whatever it is that I'm not understanding about props, or routing, or computed properties.
There are 2 issues:
1) There's an error:
Cannot use <template> as component root element because it may contain multiple nodes.
So change that to a div. When using the Vue CLI, templates are wrapped in <template> but there still needs to be a different root element inside of it.
2) The Level component has a prop called message but it isn't passed. The Home route passes id but not message. Home can't pass message at the moment, because it's in the root component, and Home didn't receive it.
You could:
Use Vuex to solve this most cleanly
Define message in Home instead of the root and pass it to Level
Pass the message from root to Home and then again from Home to Level
I have a problem with my Vue router js file.
The problem is that I need to send to a route, more than one component and multiple dynamic props.
If I send 1 component with dynamic props, it don't crash.
If I send more components with static props, it don't crash.
The problem is when I try to send more components with dynamic props to the same route.
{
path: RoutesName.RECEPTION_MULTIPLE_INVENTORY_PROCESS.RECEPTION_MULTIPLE_INVENTORY_PROCESS_PATH, // /reception/go/:id
name: RoutesName.RECEPTION_MULTIPLE_INVENTORY_PROCESS.RECEPTION_MULTIPLE_INVENTORY_PROCESS_NAME,
components: {
default: RecepcionMultipleInventoryProcess,
menu: MenuInventoryMultiple
},
props: (route) => ({
default: {
selectedReceptionIds: route.params.selectedReceptionIds,
location: route.params.location
},
menu: {
title: 'Recepciones multiples',
titleActi: 'Entradas multiples'
}
})
}
Here the snippet with multiple components and dynamic (default component) props
You use the combination of Function mode and Object mode in the wrong way.
Rewrite props like this:
props: {
default: (route) => ({
selectedReceptionIds: route.params.selectedReceptionIds,
location: route.params.location
}),
menu: {
title: 'Recepciones multiples',
titleActi: 'Entradas multiples'
}
}
Im using Vue Router. In my code I used to have:
<div v-bind:is="page.component_name" v-bind:page="page"></div>
Which worked, and the page data was passed to the component. But how do I do the same with a router-view? This doesn't seem to work:
<router-view v-bind:page="page"></router-view>
js:
var vm = new Vue({
...,
router : new VueRouter({
routes : [
{ path: '/foo', component: { template: '<div>foo</div>', created:function(){alert(1);} } },
//{ path: '/bar', component: { template: '<div>bar</div>', created:function(){alert(2);} } },
{ path: '/bar', component: Vue.component("ti-page-report") }
]
}),
...
});
vue-router has a dedicated page in docs on how to pass props to router-view.
Passing Props to Route Components
Example snippet from docs:
const router = new VueRouter({
routes: [
{ path: '/user/:id', component: User, props: true },
// for routes with named views, you have to define the `props` option for each named view:
{
path: '/user/:id',
components: { default: User, sidebar: Sidebar },
props: { default: true, sidebar: false }
}
]
})
If you are looking for simplified usage, props can still be passed the same way they are passed to any component. But component that is used for rendering the route (the one that is specified in route definition) should expect to receive the props.
Here is simple usage example of passing props to router-view:
I personally decided to use provide/inject feature: preserving reactivity with minimal overhead.
The component ("ti-page-report") that needs to access the props being sent just needs to add it:
<template>
<div>
<h1>Now you can access page: {{ page }}</h1>
</div>
</template>
export default {
name: "TiPageReport",
props: ['page'], // can now be accessed with this.page
...
};
See https://v2.vuejs.org/v2/guide/components-props.html for how to use props properly.
Suppose I have a Vue.js component like this:
var Bar = Vue.extend({
props: ['my-props'],
template: '<p>This is bar!</p>'
});
And I want to use it when some route in vue-router is matched like this:
router.map({
'/bar': {
component: Bar
}
});
Normally in order to pass 'myProps' to the component I would do something like this:
Vue.component('my-bar', Bar);
and in the html:
<my-bar my-props="hello!"></my-bar>
In this case, the router is drawing automatically the component in the router-view element when the route is matched.
My question is, in this case, how can I pass the the props to the component?
<router-view :some-value-to-pass="localValue"></router-view>
and in your components just add prop:
props: {
someValueToPass: String
},
vue-router will match prop in component
sadly non of the prev solutions actually answers the question so here is a one from quora
basically the part that docs doesn't explain well is
When props is set to true, the route.params will be set as the component props.
so what you actually need when sending the prop through the route is to assign it to the params key ex
this.$router.push({
name: 'Home',
params: {
theme: 'dark'
}
})
so the full example would be
// component
const User = {
props: ['test'],
template: '<div>User {{ test }}</div>'
}
// router
new VueRouter({
routes: [
{
path: '/user',
component: User,
name: 'user',
props: true
}
]
})
// usage
this.$router.push({
name: 'user',
params: {
test: 'hello there' // or anything you want
}
})
In the router,
const router = new VueRouter({
routes: [
{ path: 'YOUR__PATH', component: Bar, props: { authorName: 'Robert' } }
]
})
And inside the <Bar /> component,
var Bar = Vue.extend({
props: ['authorName'],
template: '<p>Hey, {{ authorName }}</p>'
});
This question is old, so I'm not sure if Function mode existed at the time the question was asked, but it can be used to pass only the correct props. It is only called on route changes, but all the Vue reactivity rules apply with whatever you pass if it is reactive data already.
// Router config:
components: {
default: Component0,
named1: Component1
},
props: {
default: (route) => {
// <router-view :prop1="$store.importantCollection"/>
return {
prop1: store.importantCollection
}
},
named1: function(route) {
// <router-view :anotherProp="$store.otherData"/>
return {
anotherProp: store.otherData
}
},
}
Note that this only works if your prop function is scoped so it can see the data you want to pass. The route argument provides no references to the Vue instance, Vuex, or VueRouter. Also, the named1 example demonstrates that this is not bound to any instance either. This appears to be by design, so the state is only defined by the URL. Because of these issues, it could be better to use named views that receive the correct props in the markup and let the router toggle them.
// Router config:
components:
{
default: Component0,
named1: Component1
}
<!-- Markup -->
<router-view name="default" :prop1="$store.importantCollection"/>
<router-view name="named1" :anotherProp="$store.otherData"/>
With this approach, your markup declares the intent of which views are possible and sets them up, but the router decides which ones to activate.
const User = {
props: ['id'],
template: '<div>User {{ id }}</div>'
}
const router = new VueRouter({
routes: [
{ path: '/user/:id', component: User, props: true }
// for routes with named views, you have to define the props option for each named view:
{
path: '/user/:id',
components: { default: User, sidebar: Sidebar },
props: { default: true, sidebar: false }
}
]
})
Object mode
const router = new VueRouter({
routes: [
{ path: '/promotion/from-newsletter', component: Promotion, props: { newsletterPopup: false } }
]
})
That is the official answer.

Use:
this.$route.MY_PROP
to get a route prop
So ive been looking into vue and been experiencing an issue which i cant seem to find the solution for. Im using Vue and Vue-router. I started with the basic vue + webpack template which gave the initial boilerplate.
I've successfully added additional routes to the predefined routes which is working as expected (games, tournaments, stats and users routes works just fine). However now im unable to get additional routes to work. the "gaming" route doesnt work, ive also tried adding additional routes which does not seem to work either.
So this is my current router file (index.js):
import Vue from 'vue'
import Router from 'vue-router'
const Gaming = () => import('#/components/gaming.vue');
const Home = () => import('#/components/home.vue');
const Game = () => import('#/components/game.vue');
const Tournament = () => import('#/components/tournament.vue');
const Users = () => import('#/components/users.vue');
const Stats = () => import('#/components/stats.vue');
const router = new Router({
routes: [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/games',
name: 'Game',
component: Game,
},
{
path: '/wtf',
name: 'Gaming',
components: Gaming,
},
{
path: '/tournaments',
name: 'Tournament',
component: Tournament
},
{
path: '/users',
name: 'Users',
component: Users
},
{
path: '/stats',
name: 'Stats',
component: Stats
}
]
});
export default router;
Vue.use(Router);
All my routes works as expected except the "Gaming" route. The "Gaming" component looks like this:
<template>
<div>
<h1>WTF?!?!?!?!?=!?!</h1>
</div>
</template>
<script>
export default {
name: 'Gaming',
components: {},
data() {
return {}
},
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style>
</style>
Ive tried to pretty much copy/paste a working component, And only change the name, as well as the template. But it seems to have issues. Initially i had done the route component imports the normal "boilerplate" way
import Stats from '#/components/Stats'
Which pretty much had the same result, Except this would cause an exception when attempting to navigate to the "gaming" route.
Cannot read property '$createElement' of undefined
at render (eval at ./node_modules/vue-loader/lib/template-compiler/index.js?{"id":"data-v-c9036282","hasScoped":false,"transformToRequire":{"video":["src","poster"],"source":"src","img":"src","image":"xlink:href"},"buble":{"transforms":{}}}!./node_modules/vue-loader/lib/selector.js?type=template&index=0!./src/components/gaming.vue (app.js:4240), <anonymous>:3:16)
All other routes worked. Ive also tried to re-create all the files and re-do the specific route which doesnt seem to work either. So im at a loss of what i can do to fix this issue?
Here i attempt to inspect the route, And as you can see the component is missing "everything"
Inspecting the route
Also tried looking with the vue addon for chrome, Where the component does not get loaded into the view
Vue Chrome Extension
Uploaded the project to gdrive if someone want to tweak around with it
Google Drive Link
Found the issue:
const router = new Router({
routes: [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/games',
name: 'Game',
component: Game,
},
{
path: '/wtf',
name: 'Gaming',
components <----------: Gaming,
// Should be component not componentS
},
{
path: '/tournaments',
name: 'Tournament',
component: Tournament
},
...
Also, you should use the standard method of importing. Without that error, I would've never found the issue.
