Uses minify-html-literals to minify HTML and CSS markup inside JavaScript template literal strings.

Usage

Install

pnpm i rollup-plugin-minify-vanilla-web-components-template-literal

Setting

// vite.config.ts
import UnoCSS from 'unocss/vite'
import { defineConfig } from 'vite'
import { splitVendorChunkPlugin } from 'vite'
import minifyHTML from 'rollup-plugin-minify-vanilla-web-components-template-literal'
const ViteMinifyHTML = minifyHTML as any

// https://vitejs.dev/config/
export default defineConfig({
  build: {
    lib: {
      formats: ['es'],
      entry: [
        'src/sample-elements-01.ts',
        'src/sample-elements-02.ts',
        'src/sample-elements-03.ts',
      ],
      fileName: (_, entryName) => {
        return `js/${entryName}.js`;
      },
    },
  },
  plugins: [
    splitVendorChunkPlugin(),
    minifyHTML(),
    UnoCSS({
      mode: 'shadow-dom',
    }),
  ]
})

By default, this will minify any tagged template literal string whose tag contains "html" or "css" (case insensitive). Additional options may be specified to control what templates should be minified.

Options

export default {
  entry: 'index.js',
  dest: 'dist/index.js',
  plugins: [
    minifyHTML({
      // minimatch of files to minify
      include: [],
      // minimatch of files not to minify
      exclude: [],
      // set to `true` to abort bundling on a minification error
      failOnError: false,
      // minify-html-literals options
      // https://www.npmjs.com/package/minify-html-literals#options
      options: null,

      // Advanced Options
      // Override minify-html-literals function
      minifyHTMLLiterals: null,
      // Override rollup-pluginutils filter from include/exclude
      filter: null
    })
  ]
};
