几个CDN的例子：
html页面：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <link rel="icon" href="/favicon.ico" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <!-- <script src="https://unpkg.com/vue@3.2.26/dist/vue.global.js"></script> <script src="https://unpkg.com/vue-router@4.0.12/dist/vue-router.global.js"></script> --> <script src="https://cdn.bootcdn.net/ajax/libs/vue/3.2.0-beta.7/vue.global.min.js"></script> <script src="https://cdn.bootcdn.net/ajax/libs/vue-router/4.0.10/vue-router.global.min.js"></script> <script src="https://cdn.bootcdn.net/ajax/libs/axios/0.21.1/axios.js"></script> <title>Vite App</title> </head> <body> <div id="app"></div> <script type="module" src="/src/main.ts"></script> </body> </html>
vite.config.js:
import { defineConfig } from "vite";
import externalGlobals from "rollup-plugin-external-globals";
import vue from "@vitejs/plugin-vue";
// https://vitejs.dev/config/
export default defineConfig({
plugins: [vue()],
build: {
rollupOptions: {
plugins: [
externalGlobals({
"vue-router": "VueRouter",
'vue':'Vue',
'axios':'axios'
}),
],
},
},
});
//其中key就是你引入的时候的名字，value就是引入的那个第三方库的全局变量名字
