How does Vue's reactivity system work with a custom API?

Can you explain how Vue's reactivity system works with a custom API?

Sure! Vue's reactivity system allows you to create reactive data properties that automatically update the UI when the data changes. When integrating with a custom API, you can fetch data and set it to a reactive property, ensuring that any changes in the API data reflect in your Vue components.

What are the key concepts I should understand about Vue's reactivity?

Key concepts include reactive properties, watchers, computed properties, and the Vue instance. Understanding how Vue tracks changes to data and updates the DOM is crucial.

How do I set up a reactive property with data from my API?

You can use the data option in your Vue component to define a reactive property. Then, use the mounted lifecycle hook to fetch data from your API and assign it to that property.

Can you provide a code example for that?

Absolutely! Here's a simple example:

export default {
  data() {
    return {
      apiData: null
    };
  },
  async mounted() {
    const response = await fetch('https://api.example.com/data');
    this.apiData = await response.json();
  }
};
