My view is like this :

<div class="panel panel-default panel-store-info">
    ...
    <div id="app">
        <AddFavoriteProduct></AddFavoriteProduct>
    </div>
    ....
</div>

My ponent is like this :

<template>
    <a href="javascript:" class="btn btn-block btn-success" @click="addFavoriteProduct({{ $product->id }})">
        <span class="fa fa-heart"></span>&nbsp;Favorite
    </a>
</template>

<script>
    export default{
        name: 'AddFavoriteProduct',
        props:['idProduct'],
        methods:{
            addFavoriteProduct(event){
                event.target.disabled = true
                const payload= {id_product: this.idProduct}
                this.$store.dispatch('addFavoriteProduct', payload)
                setTimeout(function () {
                    location.reload(true)
                }, 1500);
            }
        }
    }
</script>

When click button favorite, it will call controller on the laravel

I had register on the app.js like this :

...
import AddFavoriteProduct from './ponents/AddFavoriteProduct.vue';
...
ponents: {
                ...
                AddFavoriteProduct
            },
...

When executed, the button favorite does not appear.

Please help.

UPDATE

There exist error like this :

[Vue warn]: Unknown custom element: - did you register the ponent correctly? For recursive ponents, make sure to provide the "name" option. (found in root instance)

Whereas I had register it

• Are you using any other ponent or this is first ponent you are trying, also can you add whole of App.js if possible. which version of vue you are using – Saurabh Commented Jan 25, 2017 at 6:43
• @Saurabh, Yes, I have another ponent. Another ponent works well – moses toh Commented Jan 25, 2017 at 6:46

Three fixes that I can see...

First, omit name: 'AddFavoriteProduct' in your ponent (it's not required for single-file ponents) and use kebab-case for the ponent in your template. Second, you appear to be missing the id-product prop

<add-favorite-product :id-product="someProductIdFromSomewhere"></<add-favorite-product>

Third, you don't use interpolation in bound properties and you don't even need to pass anything other than the $event to your addFavoriteProduct method

@click="addFavoriteProduct($event)"

HTML is case-insensitive, so your custom button element <AddFavoriteProduct></AddFavoriteProduct> is being interpreted as your Vue warning reports: <addfavoriteproduct>

When you name your ponent with camelCase or PascalCase, the corresponding tag name you should be using in your markup should be kebab-cased like so: <add-favorite-product></add-favorite-product>

Vue knows to do the conversion from "dash-letter" to "uppercase-letter".

I am not used to vuex, as I generally implement my own store as a POJO object - not graduated with the learning curve of vuex. So can't provide a working solution with vuex, however to my knowledge, you need to kind of import the action(s) in your ponent - you can try the below

<template>
<a href="javascript:" class="btn btn-block btn-success" @click="addFavoriteProduct({{ $product->id }},  $event)">
    <span class="fa fa-heart"></span>&nbsp;Favorite
</a>
</template>

<script>
    export default{
        props:['idProduct'],
        vuex: {
            actions: {
                setFavoriteProduct: setFavoriteProduct
                // assuming you named the action as setFavoriteProduct in vuex
                // avoid duplicate naming for easy debugging
            }
        }
        methods:{
            addFavoriteProduct(productId, event){
                event.target.disabled = true
                const payload= {id_product: this.idProduct}
                // this.$store.dispatch('addFavoriteProduct', payload)
                this.setFavoriteProduct(payload);
                setTimeout(function () {
                    location.reload(true)
                }, 1500);
            }
        },
    }

Note: From Vuex2 the store.dispatch() accepts only one argument (not a problem with your current use case), however if you need to pass multiple arguments to your action you can work around like

store.dispatch('setSplitData',[data[0], data [1]])

// in the action:
setSplitData (context, [data1, data2]) { // uses ES6 argument destructuring

    OR

//... with an object:
store.dispatch('setSplitData',{ 
  data1: data[0], 
  data2: data [1],
})

// in the action:
setSplitData (context, { data1, data2 }) { // uses ES6 argument destructuring
//source: LinusBorg's ment at https://github./vuejs/vuex/issues/366

Are you getting any error?

One mistake I see in your code is, you are taking one parameter: event, while you are trying to pass {{ $product->id }} to it, which seems a laravel variable. (Sorry, I don't know laravel)

If you want both event and product->id in method, you have to pass both parameters from HTML, like it is in docs with help of $event

<template>
    <a href="javascript:" class="btn btn-block btn-success" @click="addFavoriteProduct({{ $product->id }},  $event)">
        <span class="fa fa-heart"></span>&nbsp;Favorite
    </a>
</template>

<script>
    export default{
        name: 'AddFavoriteProduct',  // I am not sure if name is needed, don't remember seeing it in docs
        props:['idProduct'],
        methods:{
            addFavoriteProduct(productId, event){
                event.target.disabled = true
                const payload= {id_product: this.idProduct}
                this.$store.dispatch('addFavoriteProduct', payload)
                setTimeout(function () {
                    location.reload(true)
                }, 1500);
            }
        }
    }
</script>

Another problem is you are expecting a prop idProduct, which is not being passed to ponent, You have to pass it like this in kebab-case:

<div class="panel panel-default panel-store-info">
    ...
    <div id="app">
        <AddFavoriteProduct id-product="4"></AddFavoriteProduct>
    </div>
    ....
</div>
