Highlights 💡

Improved ESM output

Optimizing ESM output has long been one of the key challenges faced by Rspack. Previously, we relied on module concatenation to optimize ESM outputs, but that approach had several limitations:

  • Impure output – The generated files contained Rspack's runtime code.
  • Prone to errors – Some modules could not be correctly concatenated, leading to unexpected runtime issues.
  • Limited code-splitting support – Split bundles became complex and difficult to analyze or optimize statically.

To address these issues once and for all, we introduced an experimental plugin called EsmLibraryPlugin, purpose-built for constructing clean and efficient ESM libraries:

  • Full control over the bundling process – All modules are linked during compilation, eliminating reliance on Rspack's runtime.
  • Code-splitting support – Code after splitting can be statically analyzed and is tree-shaking friendly.

The image below compares the code splitting output before and after using this plugin — the left side shows the previous output, while the right side shows the cleaner output produced by EsmLibraryPlugin:

Rspack 1.6 ESM output diff

In Rslib, the EsmLibraryPlugin is now integrated out-of-the-box with experiments.advancedEsm enabled to generate ESM output that is high-quality, more friendly to static analysis, and supports code splitting.

export default {
  lib: [
    {
      format: 'esm',
      bundle: true,
      experiments: {
        advancedEsm: true,
      },
    },
  ],
};

[!TIP]
Currently this option only takes effect in bundle mode when format is 'esm'.

Additional build CLI options

The Rslib build command now supports additional CLI options that take precedence over configuration file settings, and can even be used without any configuration file entirely.

For example: rslib build --entry index.ts --minify --tsconfig tsconfig.build.json.

Usage:
  $ rslib build

Options:
  -w, --watch            turn on watch mode, watch for changes and rebuild
  --entry <entry>        set entry file or pattern (repeatable)
  --dist-path <dir>      set output directory
  --bundle               enable bundle mode (use --no-bundle to disable)
  --format <format>      specify the output format (esm | cjs | umd | mf | iife)
  --syntax <syntax>      set build syntax target (repeatable)
  --target <target>      set runtime target (web | node)
  --dts                  emit declaration files (use --no-dts to disable)
  --externals <pkg>      add package to externals (repeatable)
  --minify               minify output (use --no-minify to disable)
  --clean                clean output directory before build (use --no-clean to disable)
  --auto-extension       control automatic extension redirect (use --no-auto-extension to disable)
  --auto-external        control automatic dependency externalization (use --no-auto-external to disable)
  --tsconfig <path>      use specific tsconfig (relative to project root)
