Vue 'serverPrefetch' Lifecycle Hook


Example

Using the serverPrefetch lifecycle hook to fetch data on the server side.

export default {
  data() {
    return {
      data: null,
    };
  },
  async serverPrefetch() {
    const response = await fetch("https://random-data-api.com/api/v2/users"); 
    this.data = await response.json();
  }
};

Definition and Usage

The serverPrefetch lifecycle hook only happens during server-side rendering (SSR).

The serverPrefetch lifecycle hook is used to for example fetch data, in case you need to do that exclusively on the server-side.

The serverPrefetch lifecycle hook is used as an asynchronous function, so that if it returns a promise, the server will wait with rendering the component until the promise is resolved.

Note: In the example above, the "Run Example" button is missing because the example would not work as the serverPrefetch hook will only be called during server-side rendering (SSR).
