Does node target not support chunkSplit

[longht021189]

This is my rsbuild.config.ts

import { pluginReact } from '@rsbuild/plugin-react'
import { pluginBabel } from '@rsbuild/plugin-babel'
import { pluginTypeCheck } from '@rsbuild/plugin-type-check'
import { pluginImageCompress } from '@rsbuild/plugin-image-compress'
import { pluginCssMinimizer } from '@rsbuild/plugin-css-minimizer'

export default defineConfig({
  plugins: [
    pluginCssMinimizer(),
    pluginImageCompress(),
    pluginTypeCheck({
      enable: process.env.NODE_ENV === 'production',
    }),
    pluginBabel({
      babelLoaderOptions: (config) => {
        config?.plugins?.push([
          '@stylexjs/babel-plugin',
          {
            dev: true,
            test: false,
            unstable_moduleResolution: {
              type: 'commonJS',
              rootDir: __dirname,
            },
          },
        ])
      },
    }),
    pluginReact(),
  ],
  performance: {
    chunkSplit: {
      strategy: 'split-by-experience',
      override: {
        cacheGroups: {
          react: {
            test: /[\\/]node_modules[\\/](@types[\\/])?(react|react-dom)[\\/]/,
            name: 'react',
            chunks: 'all',
          },
        },
      },
    },
  },
  output: {
    cleanDistPath: true,
    disableMinimize: true,
    targets: ['web', 'node'],
  },
  tools: {
    rspack(config, { target }) {
      const newCfg = config

      if (target === 'node') {
        newCfg.entry = './src/server.tsx'
      }

      return newCfg
    }
  }
})

And I got main.js with react-dom-server-legacy.node.production.min.js was embeded.

It's working on web target.

What did I miss in config? Please help me T.T

The node target does not support chunkSplit, usually we don’t need to split different chunks for node bundles.

Why do you need to split the chunk for node target?

[longht021189]

Hmm, I feel it's not consistency.
Latest question, if node bundle is too large, is it effect to startup performance?

[chenjiahan]

Normally this will not affect Node.js startup perf.

For splitting Node.js bundles, we can use dynamic import and it will generate separate chunks after building.
