Using Vue.js to execute an asynchronous function directly in the code

Question

Using Vue.js to execute an asynchronous function directly in the code

I am attempting to utilize a method within a v-for loop to make an API call and load an object based on a UID.

Below is the structure of my method:

methods: {
  async getTodo(uid) {
    const data = await axios.get(
      "https://jsonplaceholder.typicode.com/todos/" + uid
    );
    return data;
  }
}

I thought I could simply include the method inline like this:

{{ getTodo(2) }}

However, all it returns is [object Promise]. I must have misunderstood either the use of methods in this context or the implementation of the async call within the method. If anyone can provide clarification on what might be going wrong here, it would be greatly appreciated.

One way to manage asynchronous responses is by storing them in a dynamic array that updates whenever a promise resolves. This allows the response data to be automatically displayed as soon as it's available.

To implement this, you can utilize the following approach:

export default {
  data: {
    asyncDataHolder: []
  },
  methods: {
    async getTodo(uid) {
    const data = await axios.get(
      "https://jsonplaceholder.typicode.com/todos/" + uid
    );
    let index = asyncDataHolder.length + 1;
    asyncDataHolder.$set(index, data);
}

In your template where you have a v-for loop, you can access the stored asynchronous data like this:

{{asyncDataHolder[i]}}
