如何从构造函数中使用/导入 App.vue 中的数据

Question

I'm initializing my app with main.js like so,

import App from './App.vue';

const store = {
    items: [{
        todo: 'Clean Apartment.',
    },{
        todo: 'Mow the lawn!',
    },{
        todo: 'Pick up eggs, milk & flour',
    }, {
        todo: 'Watch the big game',
    }],
};

const app = new Vue({
    el: '#app-zone',
    data: store, // is this not sending the store data into App.vue?
    render: h => h(App),
});

I'm trying to make use of items within App.vue . But I'm not sure how or if it's passed down into it.

App.vue looks like so...

export default {
    props['items'], // not sure if that's correct
    created() {
        console.log(this.items);  // always returns undefined
    }
}

So how do I get data from the constructor and make use of it? Thank you for your help!

In order to pass props via the render function, you need to provide a context object. See https://v2.vuejs.org/v2/guide/render-function.html#createElement-Arguments

render: h => h(App, {
  props: {
    items: store.items
  }
})
