Encountering a problem with initializing a value on App.vue to the result of an asynchronous function. I attempted setting it to the resolution of a promise as well, but that did not work either. In the first scenario, only receiving an undefined value, and in the second, getting the reference type for a JavaScript promise. How can I properly initialize a variable in Vue to the result of a callback that will finish at a later time?
I find it most effective to handle this operation within the created lifecycle hook. After the asynchronous task is finished, the outcome is saved in the data property.
new Vue({
el: "#app",
data: {
asyncData: null
},
created() {
const url = 'https://jsonplaceholder.typicode.com/posts/1';
axios.get(url).then(response => {
this.asyncData = response.data;
});
}
})
Template:
<div id="app">
{{ asyncData }}
</div>
