Providing properties to the main Vue.js components

An Issue I'm Facing

I am currently attempting to pass a prop to my root constructor. To achieve this, I have been exploring the use of propsData, which I learned about from this resource:

var appComponent = Vue.component('app', require('./components/app/app.vue.html'));
new Vue({
    el: '#app-root',
    router: new VueRouter({ mode: 'history', routes: routes }),
    propsData: { test: 'hi!' },
    components: { appComponent },
    render: h => h('app')
}); 

The above code snippet pertains to the AppComponent receiving the prop:

export default class AppComponent extends Vue {

    @Prop()
    test: string;

    mounted() {
        console.log('test = ' + this.test);
        // result: test = undefined
        // expected: test = 'hi!'
    }
}

Attempts and Experiments

To make it function correctly during development (although not in production), I tried the following approach:

test: string;

beforeCreate() {
    this.test = this.$root.test;
}

This method proved to be effective on a development environment (specifically Windows). However, upon deployment (on Linux), I encountered a TypeScript error:

ERROR in [at-loader] ClientApp/components/app/app.ts:14:34
    TS2339: Property 'test' does not exist on type 'Vue'.

Answer №1

To include props in the data object, you can pass them as part of the 2nd argument within the createElement function using the alias h in the render option.

render: h => h('app', { props: { test: 'hi!' }})
