Passing Props to Route Component

Passing Props to Route Component: this means to pass props by router.

There are two options to receive props:
first one is inside template: $route.params.id
second one is as props inside vue component : props: ['id']

 Example:
product.js for router file
import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

const navBar = {
template: `<div>
<ul>
<li><router-link v-bind:to="{ path:'list' }">Product all</router-link></li>
</ul>
</div>`
}

const setting = {
template: `
<div>
<navBar />
<router-view />
<router-view name='status' />
<router-view name='detail' />
</div>`,
components:{
navBar
}
}

const status = {
template: `<div> product status </div>`
}

const detail = {
props:['id'],
template: `<div> product detail Id: {{ id }} </div>`
}

const products = {
template:`<div>
<li v-for="product in products" v-bind:key="product.id">
id: {{product.id}}, name: {{product.name}}, status: {{ product.status}}
<br/>
<router-link v-bind:to="{ name: 'detail', params:{id:product.id }}">Product detail</router-link>
</li>
</div>`,
watch:{
'$route' (to, from){
console.log(from)
}
},
data () {
return {
products:[
{id:1, name:'motobike', status:'old'},
{id:2, name:'fan', status:'new'},
{id:3, name:'watch', status:'new'},
{id:4, name:'glasses', status:'old'}
]
}
},
}
const routes = [
{ path: '/',
name: 'setting',
component: setting,
children:[
{
path:'products',
name:'products',
alias: 'list',
components:{
default:products,
status:status
}
},
{
path:'detail/:id',
name:'detail',
components:{
detail:detail
},
props: { detail : true }
}
]
}
]

const router = new VueRouter({
mode:'history',
routes // short for `routes: routes`
})
export { router }

As you see above code, detail component contains props id:
const detail = {
props:['id'],
template: `<div> product detail Id: {{ id }} </div>`
}

How to pass props from route configuration file.
{
path:'detail/:id',
name:'detail',
components:{
detail:detail
},
props: { detail : true }
}
We have path:'detail/:id' and props:{ detail: true}. this means that we pass id as props from template to detail component.

How we pass id props from template is here.
<router-link v-bind:to="{ name: 'detail', params:{id:product.id }}">Product detail</router-link>

Props can be passed as function:

props: (route) => ({ id: route.query.id})

App.vue component file
<template>
<div id="app">
<h2>Products</h2><br/>
<router-view></router-view>
</div>
</template>

<script>
import { router } from './routes/product';

export default {
name: 'app',
router,
methods:{
goProduct( productId = null ) {
if(productId) {
this.$router.push({ name:'product', params:{ id:productId } })
}
}
}
}
</script>

Vuex mapMutations

Image
VueX mapMutations: is used simply to replace this.$store.commit('abc') to   mapMutations(['abc','..']) . its functionalities are the same but mapMutations is more preferable and useful as it is able to combine different functions in mutations into one. Example: App.vue < template > < div id = "app" > < Counter /> </ div > </ template > < script > import { store , Counter } from './state/simple' export default { name: 'app' , store , components: { Counter }, data () { return { placeHolder: 'Focus on me' } }, } </ script > simple.js import Vue from 'vue' ; import Vuex , { mapGetters , mapMutations } from 'vuex' ; Vue . use ( Vuex ) const store = new Vuex . Store ({ state: { products: [ { id: 1 , name: 'pizza' , price: 10 }, ...

VueX Actions

Image
VueX Actions: can be used interchangeably with mutations however, actions  be used to commit mutations asynchronously whereas mutations can only be synchronous. Vuex Actions accepts context object as argument for each handler functions and this context contains commit, state, getters, and dispatch as it store instance. In order to call handler functions inside Actions properties from vue component, we use this.$store.dispatch('deductPrice').  When it dispatches from vue component, actions handler function will call mutations handler function with payload injected. Example: simple.js import Vue from 'vue' ; import Vuex , { mapGetters , mapMutations } from 'vuex' ; Vue . use ( Vuex ) const store = new Vuex . Store ({ state: { products: [ { id: 1 , name: 'pizza' , price: 10 }, { id: 2 , name: 'fan' , price: 20 }, { id: 3 , name: 'headset' , price: 30 }, { id: 4 , name: 'phone' , price: ...

VueX Modules

Image
VueX Modules: is important for large scale project as it make developer more easier to separate store state as module for example moduleOne and moduleTwo. Each module has its own state, getters, actions, mutations and namespace . However, namespace is optional. Nevertheless, it is best practice to have it to prevent some conflicts among modules state, actions, getters, mutations. Example: I have two modules with namespace inside. moduleOne const moduleOne = { namespaced: true , state: { products: [ { id: 1 , name: 'pizza' , price: 10 }, { id: 2 , name: 'fan' , price: 20 }, { id: 3 , name: 'headset' , price: 30 }, { id: 4 , name: 'phone' , price: 1004 } ] }, mutations: { deductPrice ( state ) { return state . products . map ( item => item . price -= 1 ) }, multPrice ( state , payload ) { return state . products . map ( item => i...
