1. Definitions and roles

  • vite:compiled is a hook in Vite that allows developers to perform certain actions immediately after Vite is compiled.
  • With this hook, developers can perform state logging, trigger notifications, or other custom logic after the code is compiled.

2. Timing of the call

vite:compiled The hook is triggered at the immediate stage after Vite has compiled the file, when it can be ensured that the compiled resources are up-to-date.

3. Example usage

Here's how to usevite:compiled A basic example of a hook that shows how to add custom logic after Vite has finished compiling.

existplugins/ Implementation in the document

// plugins/
import { defineNuxtPlugin } from '#app';

export default defineNuxtPlugin((nuxtApp) => {
  ('vite:compiled', () => {
    ('Vite compilation complete'); {

    // Other custom logic can be executed here
    // For example, sending a notification or updating a status.
  }); })
}).

5. Application scenarios

5.1 Implementing customized logic

You can perform some custom logic after the compilation is complete, such as sending a request to an API to notify the external service that the compilation was successful.

('vite:compiled', () => {
  const notifyCompletion = async () => {
    try {
      const response = await fetch('/api/notifyCompilationComplete', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
      });
      const data = await ();
      ('Notification of results:', data);
    } catch (error) {
      ('Notification of request failure:', error);
    }
  };

  notifyCompletion();
});

5.2 Generating compilation information

During development, it may be useful to log compilation information. In the hook, you can output the status of the compilation.

('vite:compiled', () => {
  const timestamp = new Date().toISOString();
  (`[${timestamp}] Compilation completed`);
});

5.3 Triggering Hot Updates

You can trigger a hot update after the compilation is complete to ensure that developers see the latest changes.

('vite:compiled', () => {
  ('Trigger a hot update to update the compiled module...') ;
  // Hot updates can be implemented here by triggering a custom event
});

6. Cautions

6.1 Performance considerations

existvite:compiled When adding custom logic to hooks, be aware of the possible performance impact. Try to avoid performing blocking operations, especially for long-running tasks.

6.2 Asynchronous processing

If you perform an asynchronous operation (e.g. an API request) in a hook, ensure that the Promise is handled correctly. you can use theasync/await maybe.then() to manage asynchronous processes.

6.3 Differences between development and production environments

The logic performed may need to be different in different environments. You can customize the logic based on the.NODE_ENV value that determines whether to perform certain operations.

('vite:compiled', () => {
  if (.NODE_ENV === 'development') {
    ('Execute additional logic in development mode'); {
  }
});

7. Summary

By using thevite:compiled hooks, developers are able to perform custom actions while Vite is compiling, further improving development efficiency and user experience. Hooks such as
