Using

npm i vite-plugin-xk-compression -D

/* vite.config.ts */
import { viteCompression, type ViteCompress} from "vite-plugin-xk-compression";

export default defineConfig({
    plugins: [
        viteCompression('gzip') // -- type: ViteCompress
    ],
});

Type

type ViteCompress = "none" | "brotli" | "gzip" | "both" | "brotli-clear" | "gzip-clear" | "both-clear";

/**
 * none:            不压缩
 * gzip:            gz 压缩
 * brotli:          br 压缩
 * both:            gz + br 压缩
 * 
 * + ↓ 下面同理，不过下面的不会保留源文件
 * 
 * brotli-clear
 * gzip-clear
 * both-clear
