1. Definitions and roles
-
vite:configResolved
is a hook in Vite that allows certain actions to be performed after the Vite configuration has been parsed. - With this hook, developers can access the final Vite configuration and further process it as needed.
2. Timing of the call
vite:configResolved
The hook is invoked as soon as Vite configuration parsing is complete, at which point all default values and user configuration are merged together to form the complete configuration object.
3. Description of parameters
The hook receives two parameters:
-
viteInlineConfig
: A parsed Vite configuration object containing user configuration and default values. -
env
: The current environment variable, which can be used to do the appropriate logical processing according to different environments.
4. Example usage
Here's how to usevite:configResolved
A basic example of a hook showing how to access a parsed Vite configuration.
existplugins/
Implementation in the document
// plugins/
import { defineNuxtPlugin } from '#app';
export default defineNuxtPlugin((nuxtApp) => {
('vite:configResolved', (viteInlineConfig, env) => {
// Output the resolved Vite configuration
('Parsed Vite Config:', viteInlineConfig); {
// Dynamically adjust the configuration to the current environment
if (env.NODE_ENV === 'development') {
= {
... ,
open: true, // Automatically open the browser in development mode.
};
}
}).
}).
5. Application scenarios
5.1 Accessing parsed configurations
Seamless access to the complete Vite configuration during the build process for easy debugging and tracking of configuration changes:
// Output the current Vite root directory
('Vite Root Directory:', );
5.2 Adaptation of the configuration to the environment
You can dynamically adjust your Vite configuration based on different environment variables to better meet the needs of your development and production environments:
if (env.NODE_ENV === 'production') {
= 'terser'; // use a better compression tool in the production environment
}
6. Cautions
- safety: Ensure that operations on configurations do not affect other features that depend on Vite configurations to avoid unnecessary errors.
- performances: While it is possible to modify the Vite configuration, try to keep the operation as simple as possible to avoid performance degradation.
7. Summary
By using thevite:configResolved
hooks, developers can easily access and work with parsed Vite configurations, providing more flexibility in the project build process. Whether it's dynamically tweaking configurations or debugging them, thevite:configResolved
Both provide powerful tools for developers
