How to pass data to a component in Vue.js

In this tutorial, you’ll learn the basics of passing data to child components with Props.

In Vue.js, components can have custom attributes (Props). You can register props on a component and pass a value to them.

Consider this example, we have a page (Products.vue) with a list of tech products. Each product has a product card, which shows the product title and featured image.

new Vue({
  el: "#app",
  data: {
    products: [
      { title: "Hololens", image: 'https://.../image.jpg' },
      { title: "Google Glass", image: 'https://.../image2.jpg' },
      { title: "PlayStation 5", image: 'https://.../image3.jpg' }
    ]
  }
})

Create a component in Vue.js

We can now create a <product-card> component and import it to our Products.vue component.

Vue.component('product-card', {
  props: ['product'],
  template: `
    <div class="product-card">
      <h3>{{ product.title }}</h3>
      <img :src="product.image"/>
    </div>
  `
})

Our <product-card> component accepts a single product prop, which can contain multiple product attributes (product title, image etc).

Render a list of objects by passing data with props

The example above will render product cards by passing data to a child component with props. We’re using v-for to loop through products in our data object.
