Import modules from CDN with vite plugin

Import modules from CDN with vite plugin

English | 简体中文

Allows you to specify modules to be introduced in a production environment using a CDN.

This can reduce build time and improve page load speed in production environments.

Installation

Install the plugin with npm:

npm install vite-plugin-cdn-import --save-dev

or yarn

yarn add vite-plugin-cdn-import -D

Basic Usage

Add it to vite.config.js

// vite.config.js
import reactRefresh from '@vitejs/plugin-react-refresh'
import importToCDN from 'vite-plugin-cdn-import'

export default {
    plugins: [
        importToCDN({
            modules: [
                {
                    name: 'react',
                    var: 'React',
                    path: `umd/react.production.min.js`,
                },
                {
                    name: 'react-dom',
                    var: 'ReactDOM',
                    path: `umd/react-dom.production.min.js`,
                },
            ],
        }),
    ],
}

Use autoComplete

// vite.config.js
import reactRefresh from '@vitejs/plugin-react-refresh'
import importToCDN, { autoComplete } from 'vite-plugin-cdn-import'

export default {
    plugins: [
        importToCDN({
            modules: [
                autoComplete('react'),
                autoComplete('react-dom')
            ],
        }),
        reactRefresh(),
    ],
}
