1. Definitions and roles

  • webpack:configResolved is a hook to be triggered after the Webpack configuration has been parsed.
  • This hook allows developers to read and modify the determined Webpack configuration to meet specific project requirements.

2. Timing of the call

webpack:configResolved The hook is triggered as soon as the Webpack configuration is parsed, at which point the final configuration object can be accessed.

3. Description of parameters

This hook takes one argument:

  • webpackConfigs: This is an array of objects containing the parsed Webpack configuration. Developers can read and modify this configuration.

4. Example usage

Here's how to usewebpack:configResolved A basic example of a hook showing how to perform a custom action after the configuration has been resolved.

existplugins/ Implementation in the document

// plugins/

export default defineNuxtPlugin((nuxtApp) => {
  ('webpack:configResolved', (webpackConfigs) => {
    // Print the resolved configuration
    ('Parsed Webpack Configuration:', webpackConfigs); {

    // Iterate through each configuration and make changes
    ((config) => {
      // Here you can modify the configuration items as needed.
    });
  });
}).

5. Application scenarios

5.1 Checking and Printing Configurations

During development, you may need to check and validate parsed Webpack configurations to ensure that they meet expectations.

('webpack:configResolved', (webpackConfigs) => {
  ((config) => {
    ('Final Webpack Configuration:', (config, null, 2)); {
  });
});

5.2 Changing the output path or file name

You may want to make changes to the configured output settings at build time, such as updating the output path or filename.

('webpack:configResolved', (webpackConfigs) => {
  ((config) => {
    // Modify the output path
     = (__dirname, 'dist'); { (config) => { // Modify the output path.
    // Modify the output filename
     = '[name]. [contenthash].js';
  }).
}).

5.3 Adding Custom Global Variables

You can add custom global variables to your Webpack configuration for use in other modules in your project.

('webpack:configResolved', (webpackConfigs) => {
  ((config) => {
    // Define global variables
    (new ({
      '.CUSTOM_VARIABLE': ('my-value'),
    }));
  });
});

6. Cautions

  • Careful modification: Ensure that changes are made with an understanding of the meaning of the configuration item to avoid introducing unnecessary errors.
  • Record changes:: Proper documentation of changes made to facilitate future inspection and maintenance.
  • test (machinery etc): After making changes to the configuration, it is a good idea to execute a build and perform full functional testing to ensure that no new problems have been introduced.

7. Summary

By using thewebpack:configResolved hooks, developers can read and modify the Webpack configuration after it has been parsed. This provides greater flexibility for projects and helps meet the challenges of various project requirements and environments.
