1. General

page:finish is a hook that is called after the page has finished loading and the Suspense state has been resolved. It allows the developer to perform necessary actions after the page has finished rendering, such as hiding the load indicator, logging, or performing state updates.

2. Detailed description of the page:finish hook

2.1 Definition and role of hooks

page:finish The main functions of the hook include:

  • Hide the loading indicator
  • Implementation analysis or statistics
  • Updating a component's state or UI

2.2 Timing of calls

  • Execution environment: This hook is executed only on the client side.
  • timing of mounting: When the page finishes loading and the Suspense state is resolved, thepage:finish is triggered. This is usually when the user successfully navigates to a new page.

2.3 Return Values and Exception Handling

Hooks have no return value. Developers should properly handle any possible exceptions within the hook to ensure that the application is not interrupted by errors.

3. Specific examples of use

3.1 Basic Usage Examples

Suppose we want to remove the loading animation after the page has finished loading, we can do this with thepage:finish to realize:

// plugins/
export default defineNuxtPlugin({
    hooks: {
        'page:finish'() {
            ('Page loading finished');
            // Hide loading animation
            ('loading');
        }
    }
});

In this example, we remove the loading styles that are displayed when the page load is complete.

3.2 Use in combination with other hooks

can be combined withpage:start and other hooks are used in combination to provide a smoother user experience:

// plugins/
export default defineNuxtPlugin({
    hooks: {
        'page:start'() {
            ('Page loading started');
            ('loading');
        },
        'page:finish'() {
            ('Page loading finished');
            ('loading');
        }
    }
});

This example shows how to present good user feedback by displaying the loading indicator when the page starts loading and removing it when loading is complete.
