vite plugin singlefile compression

Compress all assets and embeds them into dist/index.html, making it convenient to share as a single HTML file.

The recipient can open it directly in the browser without manually unzipping the file.

Using DecompressionStream + base128-ascii.

Setup

npm i vite-plugin-singlefile-compression@latest -D

Then modify vite.config.ts, like test/vite.config.ts

+ import singleFileCompression from 'vite-plugin-singlefile-compression'

  export default defineConfig({
    plugins: [
      vue(),
      vueDevTools(),
+     singleFileCompression(),
    ],

Then use hash history, like test/src/router/index.ts

  const router = createRouter({
-   history: createWebHistory(),
+   history: createWebHashHistory(),

Example:

singleFileCompression({
  rename: 'example.html'
}),
