Experimental Bundler Integrations

⚠️ Experimental: @vizejs/unplugin and @vizejs/rspack-plugin are still unstable. @vizejs/vite-plugin remains the recommended and best-tested bundler integration today.

Vize provides an experimental unplugin package for rollup, webpack, and esbuild, plus a dedicated Rspack package:

• @vizejs/unplugin — rollup / webpack / esbuild
• @vizejs/rspack-plugin — Rspack only

Rspack intentionally does not go through the shared unplugin path. Its loader chain, experiments.css, and HMR behavior need Rspack-specific handling.

Installation

Install vp once from the Vite+ install guide, then add the packages:

vp install @vizejs/unplugin

For Rspack:

vp install -D @vizejs/rspack-plugin @rspack/core

rollup

// rollup.config.mjs
import vize from "@vizejs/unplugin/rollup";

export default {
  plugins: [vize()],
};

webpack

// webpack.config.mjs
import Vize from "@vizejs/unplugin/webpack";

export default {
  plugins: [Vize()],
};

esbuild

// build.mjs
import { build } from "esbuild";
import vize from "@vizejs/unplugin/esbuild";

await build({
  entryPoints: ["src/main.ts"],
  bundle: true,
  plugins: [vize()],
});

Rspack

Use the dedicated @vizejs/rspack-plugin package instead of @vizejs/unplugin:

// rspack.config.mjs
import { VizePlugin } from "@vizejs/rspack-plugin";

export default {
  experiments: {
    css: true,
  },
  module: {
    rules: [
      {
        test: /\.vue$/,
        loader: "@vizejs/rspack-plugin/loader",
      },
    ],
  },
  plugins: [new VizePlugin()],
};

See the package README for the full Rspack configuration surface.

Caveats

• Vite is still the recommended integration if you need the most complete and best-tested behavior.
• CSS Modules and style preprocessors outside Vite depend on the host bundler's CSS pipeline and are more likely to change.
• If your bundler inlines the Vue runtime instead of externalizing it, make sure the usual Vue compile-time feature flags are configured for that bundler.
• Treat these integrations as experimental and validate them against your own application before rollout.
