How to use x-template to separate out template from Vue Component

You define X-Templates in your HTML file. See below for a brief demo

// this is the JS file, eg app.js
Vue.component('my-checkbox', {
    template: '#checkbox-template',
    data() {
        return { checked: false, title: 'Check me' }
    },
    methods: {
        check() { this.checked = !this.checked; }
    }
});

new Vue({el:'#app'})

/* CSS file */
.checkbox-wrapper {
  border: 1px solid;
  display: flex;
}
.checkbox {
  width: 50px;
  height: 50px;
  background: red;
}
.checkbox.checked {
  background: green;
}

<!-- HTML file -->
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.17/dist/vue.min.js"></script>
<script type="text/x-template" id="checkbox-template">
    <div class="checkbox-wrapper" @click="check">
        <div :class="{ checkbox: true, checked: checked }"></div>
        <div class="title">{{ title }}</div>
    </div>
</script>
<div id="app"> <!-- the root Vue element -->
  <my-checkbox></my-checkbox> <!-- your component -->
</div>

Sorry for my bad english it's not my main language!

Try it!

You need generate two file in same directory:

• path/to/checkboxComponent.vue
• path/to/checkboxComponent.html

In checkboxComponent.vue file

<script>
// Add imports here eg:
// import Something from 'something';
export default {
    template: require('./checkboxComponent.html'),
    data() {
        return { checked: false, title: 'Check me' }
    },
    methods: {
        check() { this.checked = !this.checked; }
    }
}
</script>

In checkboxComponent.html file

<template>
    <div class="checkbox-wrapper" @click="check">
        <div :class="{ checkbox: true, checked: checked }"></div>
        <div class="title"></div>
    </div>
</template>

Now you need to declare this Component in same file you declare Vue app, as the following:

Vue.component('my-checkbox', require('path/to/checkboxComponent.vue').default);

In my case

I have three files with these directories structure:

js/app.js
js/components/checkboxComponent.vue
js/components/checkboxComponent.html

In app.js, i'm declare the Vue app, so the require method path need to start with a dot, like this:

Vue.component('my-checkbox', require('./components/checkboxComponent.vue').default);
