Vite 3.0.8 compatibility

Hi

After upgrading to Vite 3.0.8 i encountered a problem.

Rollup/vite config:

import { defineConfig, loadEnv, PluginOption } from 'vite';
import react from '@vitejs/plugin-react';
import { visualizer } from 'rollup-plugin-visualizer';

// https://vitejs.dev/config/
export default defineConfig(({ mode }) => {
  const env = loadEnv(mode, process.cwd(), '');

  return {
    resolve: {
      preserveSymlinks: true,
      alias: {
        '@': fileURLToPath(new URL('./src', import.meta.url)),
      },
    },
    define: {
      APP_VERSION: JSON.stringify(env.npm_package_version),
    },
    build: {
      emptyOutDir: true,
      sourcemap: mode !== 'production',
    },
   // ...
    plugins: [
      react(),
      // ...
      visualizer({
        brotliSize: true,
        gzipSize: true,
        template: 'treemap',
        filename: 'stats/rollup-stats.html',
        title: 'D-Main - Rollup (Build) stats',
      }),
    ],
  };
});

Versions and OS:

• macbook pro m1 macos 12.5
• vite: 3.0.8
• rollup-plugin-visualizer: 5.7.1

Error:

• Type ‘(PluginOption[] | Plugin)[]’ is not assignable to type ‘PluginOption[]’.

If I remove “visualizer(…)” or cast it as “PluginOption” than the error goes away. This error occurred only after upgrading from 3.0.1 to 3.0.8

Is this rollup plugin not compatible anymore with the newest version?

@zmrl010 seems right, i will wait until vite 3.1. As workaround just cast to PluginOptions or pin rollup to 2.77.3

I added rollup to be optional peer dependency and it seems fixed the issue (need to drop node modules and lock file)

npm ls rollup
test-rollup@0.0.0 /home/den/rollup-vite-repro
├─┬ rollup-plugin-visualizer@5.8.1
│ └── rollup@2.77.3
