v2.1.4

Highlights

Faster ESM output builds

Building with output.module is now much faster. A lodash-es production build went from 503.8 ms to 161.6 ms (-67.9%).

Fine-grained import.meta parser options

module.parser.javascript.importMeta now accepts an object so each known import.meta property can be configured independently, on top of the existing true / false / 'preserve-unknown' values. Properties set to false are preserved for runtime evaluation, omitted properties keep their default behavior, and unknown properties are preserved. Both webpack-compatible keys (dirname, filename, main, url, webpack, webpackContext) and Rspack-specific keys (rspackHash, rspackPublicPath, glob, ...) are supported.

export default {
  module: {
    parser: {
      javascript: {
        importMeta: {
          // keep `import.meta.url` for runtime evaluation
          url: false,
          // keep the compile-time replacement of `import.meta.webpack`
          webpack: true,
        },
      },
    },
  },
};

Static worker URL output

module.parser.javascript.worker now accepts an object form with alias and url, alongside the existing boolean and string[] forms. With url: 'new-url-relative' and output.module enabled, Rspack emits a static new URL() expression for new Worker(new URL(..., import.meta.url)) instead of runtime code, honoring output.publicPath and output.workerPublicPath.

export default {
  output: {
    module: true,
    chunkFilename: '[name].bundle.js',
  },
  module: {
    parser: {
      javascript: {
        worker: {
          url: 'new-url-relative',
        },
      },
    },
  },
};
new Worker(new URL('./worker.js', import.meta.url));

// would become 👇
new Worker(new URL('./worker.bundle.js', import.meta.url));

What's Changed

Highlights 💡

Support import.meta style module variables

Rspack now exposes more module variables through import.meta, which aligns better with the ESM specification than CommonJS-style injected globals. When authoring ESM modules, import.meta is now the recommended way to access these runtime values.

The newly supported import.meta properties are:

New import.meta API Existing runtime variable
import.meta.rspackPublicPath __webpack_public_path__
import.meta.rspackBaseUri __webpack_base_uri__
import.meta.rspackShareScopes __webpack_share_scopes__
import.meta.rspackInitSharing __webpack_init_sharing__
import.meta.rspackNonce __webpack_nonce__
import.meta.rspackUniqueId __rspack_unique_id__
import.meta.rspackVersion __rspack_version__
import.meta.rspackHash __webpack_hash__

New Features 🎉

  • feat: support import.meta style module variables (#14539 by @LingyuCoder)

Performance 🚀

  • perf: deduplicate runtime module macro glue (#14620 by @intellild)
  • perf: avoid cloning side effects artifact in module concatenation (#14622 by @hardfist)

Bug Fixes 🐞

  • fix(browser): inject runtime require into browser MF runtime (#14590 by @CPunisher)
  • fix(ci): build wasm in release debug so the wasm binding gets published (#14614 by @stormslowly)
  • fix(rslib): preserve import phase in dynamic import external rendering (#14615 by @elecmonkey)
  • fix: empty references export for cjs and dynamic import tree shaking (#14629 by @ahabhgk)

Highlights 💡

Support React Compiler in builtin:swc-loader

React projects can now use React Compiler directly through Rspack's built-in SWC loader. See the React Compiler guide for details.

export default {
  module: {
    rules: [
      {
        test: /\.[cm]?[jt]sx?$/,
        loader: 'builtin:swc-loader',
        options: {
          jsc: {
            transform: {
              reactCompiler: true,
            },
          },
        },
      },
    ],
  },
};

Side-effect-free function analysis by default

Rspack's side-effect-free function analysis is now enabled by default in production builds. It can detect pure function calls through the #__NO_SIDE_EFFECTS__ notation and pureFunctions configuration, including exported functions across module boundaries. When the returned value is unused, Rspack can remove the call more reliably and improve tree shaking results without extra configuration. See experiments.pureFunctions for details.

// lib.js
/*@__NO_SIDE_EFFECTS__*/ 
export function call() {
  console.log('hi')
}

// barrel.js
import { call } from './lib'

const value = call()

// if value is unused, call can be removed
export { value }
