Highlights 💡

🎉 Support for import.meta.filename, import.meta.dirname, and import.meta.resolve

Rspack now supports the import.meta.filename, import.meta.dirname, and import.meta.resolve meta properties in ESM modules. These properties provide a standardized way to access file and directory paths in ES modules, similar to the CommonJS __filename and __dirname variables:
```
// Get the absolute path of the current module file
console.log(import.meta.filename);
// e.g., "/path/to/project/src/index.js"

// Get the directory path of the current module
console.log(import.meta.dirname);
// e.g., "/path/to/project/src"

// Resolve a module specifier to an absolute URL
const resolvedPath = import.meta.resolve('./utils.js');
```

Highlights 💡

Compact module factories

Rspack now generates a more compact module factory format that trims the wrapper function. Benchmarks show this reduces bundle size by about 1% before gzip.

What's Changed

Highlights 💡

EsmLibraryPlugin supports preserveModules

EsmLibraryPlugin now provides experimental support for the preserveModules feature. This allows you to maintain your source code structure as is while bundling all libraries within the node_modules folder. You can try it out using the following configuration example:

Feel free to copy and use it!
```
import { rspack } from "@rspack/core";
import path from 'node:path'

export default{
  entry: "./index.js",
  output: {
    chunkFormat: false,  // required, EsmLibraryPlugin handles how chunk renders 
    chunkLoading: 'import',  // required, using es module dynamic import syntax to load other chunks
  },
  optimization: {
    runtimeChunk: true,  // recommended if you have async chunks
    concatenateModules: false,  // required, EsmLibraryPlugin handles scope hoisting
  },
  plugins: [
    new rspack.experiments.EsmLibraryPlugin({
      preserveModules: path.resolve(__dirname, './src')
    })
  ],
};
```
Experimental supports for defer import

Rspack now supports defer import, you can enable it by experiments.deferImport = true. It is worth noting that we currently only support import defer, import.defer() will be implemented in the near future.
```
export default {
  experiments: {
    deferImport: true
  }
}
```

Release notes


🧪 Enhanced ESM library output (experimental)

Rspack now provides a new ESM library output that is cleaner, statically analyzable, and supports custom chunk splitting.

This new output format is fully independent of the existing chunk loading logic — each chunk can be used in isolation, and all exports are placed at the top level instead of being wrapped inside the __webpack_modules__ closure.
- Before:
```
exports.modules = { 
  "src/async-module.js": function(exports) {
    __webpack_require__.d(exports, {
      foo: () => foo
    })
    const foo = 42
  }
}
```
- After:
```
// src/async-module.js
const foo = 42

export { foo }
```
If you'd like to try this now, follow this example:
```
import { rspack } from "@rspack/core";

export default{
  entry: "./index.js",
  output: {
    chunkFormat: false,  // required, EsmLibraryPlugin handles how chunk renders 
    chunkLoading: 'import',  // required, using es module dynamic import syntax to load other chunks
  },
  optimization: {
    runtimeChunk: true,  // recommended if you have async chunks
    concatenateModules: false,  // required, EsmLibraryPlugin handles scope hoisting
  },
  plugins: [new rspack.experiments.EsmLibraryPlugin()],
};
```
We'll make this out-of-box in Rslib soon.

See EsmLibraryPlugin for more.

🎯 Layers is now stable

The layer feature is now enabled by default - you no longer need to enable it manually using the experiments.layer option.

Layers is a feature that helps you group certain modules and their dependencies, allowing you to bundle them using different transforms.

For example, you can generate both ES5 and ES2015 outputs in one compilation by assigning different layers to different entries with the following configuration:
```
export default {
  entry: {
    legacy: {
      import: "./index.js",
      layer: "es5",
    },
    modern: {
      import: "./index.js",
      layer: "es6",
    },
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        oneOf: [
          {
            issuerLayer: "es5",
            use: [
              {
                loader: "builtin:swc-loader",
                options: {
                  jsc: {
                    target: "es5",
                    // ...
                  },
                },
              },
            ],
          },
          {
            issuerLayer: "es6",
            use: [
              {
                loader: "builtin:swc-loader",
                options: {
                  jsc: {
                    target: "es2015",
                    // ...
                  },
                },
              },
            ]
          },
        ],
      },
    ],
  },
};
```
📄 Extract existing source maps

Rspack now supports extracting existing source map data from files (from their //# sourceMappingURL comment) via Rule.extractSourceMap. This feature is particularly useful for preserving source maps provided by third-party libraries, ensuring that debugging information remains accurate even when those libraries are bundled or transformed.

It was originally introduced in webpack v5.102.0 as a built-in replacement for the source-map-loader plugin, offering better performance and tighter integration with the build process.
```
export default {
  // ...
  module: {
    rules: [
      {
        test: /\.m?js$/,
        extractSourceMap: true,
      },
    ],
  },
};
```
✅ Lazy barrel enabled by default

Since Rspack v1.5 introduced experimental barrel file optimization, it has been enabled by default in Rsbuild to collect early feedback.

After extensive usage and validation within Rsbuild, we now consider lazyBarrel stable, and it is enabled by default in Rspack as well.

Highlights 💡

Enhanced Tree Shaking for Nested Exports in Destructuring

Rspack now supports more precise tree shaking for nested exports accessed through destructuring assignments.
```
// lib.js
export * as a from "./a";
export * as b from "./b";

// index.js
import * as lib from "./lib";
// Before: All exports under `lib.a` were retained, only `lib.b` was tree-shaken
// Now: Only the specific property `inner` from `lib.a` is kept; everything else is removed
const { a: { inner } } = lib;
```

Highlights 💡

Improved Tree Shaking for Dynamic Import .then()

This release enhances tree shaking capabilities specifically for the .then() callbacks of dynamic imports. Rspack can now statically analyze and eliminate unused exports when destructuring is performed on the resolved module within promise chains:
```
// Tree shaking now works for destructuring in .then() callbacks
import('./utils').then(module => {
  const { usedFunction } = module; // Only usedFunction will be included
  usedFunction();
  // unusedFunction will be tree-shaken out
});
```
JSX Preserve Support

Rspack now supports parsing and preserving JSX syntax. This allows JSX syntax to be parsed without transformation, making it compatible with external JSX transformers.
```
// rspack.config.js
export default {
  module: {
    parser: {
      javascript: {
        jsx: true // Enable JSX parsing
      }
    },
    rules: [
      {
        test: /\.jsx?$/,
        use: {
          loader: 'swc-loader',
          options: {
            jsc: {
              parser: { jsx: true },
              transform: {
                // Preserve JSX syntax
                react: { runtime: 'preserve' }
              }
            }
          }
        }
      }
    ]
  }
};

Release notes


Highlights

Here's a sneak peek at the exciting new features coming in Rspack 1.5.0.

Module Federation Module Hoisting

https://github.com/web-infra-dev/rspack/pull/10524

This update introduces a runtime module that initializes federation during Rspack's runtime phase—similar to Webpack v1's Module Federation. The federation runtime is hoisted into runtime chunks, bypassing normal code-splitting rules, so it's eagerly available at startup.

Impact: In multi-entry applications using Module Federation, this can reduce bundle size by ~60%.

Rspack's Built-in Watcher

https://github.com/web-infra-dev/rspack/pull/10658

We've implemented a Rust-based file system watcher to improve performance in large-scale file change scenarios. Moving file watching into Rust also cuts down on overhead across the NAPI boundary.

Custom Native Binding

https://github.com/web-infra-dev/rspack/pull/10857

Want to build high-performance plugins for Rspack? This feature makes it easier. If writing a Rust plugin feels daunting, check out The Rspack Book—the first section covers customizing a Rspack binding step-by-step.

🎉 @rspack/browser

https://github.com/web-infra-dev/rspack/pull/10870

Yes, you can now run Rspack directly in the browser! We've even built a web REPL so you can try it instantly: repl.rspack.rs 🚀

Built-in Virtual Module Plugin

https://github.com/web-infra-dev/rspack/pull/11021

Thanks to @nilptr's contribution, Rspack now includes a built-in Virtual Modules plugin. If you work with a large number of virtual modules, this plugin helps Rspack maintain top performance even at scale.

Drop support for Node 16

https://github.com/web-infra-dev/rspack/pull/11338

@rspack/core v1.5 will no longer support Node 16, as Node.js reached end-of-life on September 11th, 2023. Many npm packages in the ecosystem have also dropped support for Node 16 (such as webpack-dev-server, css-loader, sass-loader, etc.), making it increasingly difficult to maintain compatibility.

Package v1.4 v1.5

@rspack/core >=16.0.0 >=18.12.0

@rspack/cli >=18.12.0 >=18.12.0

@rspack/dev-server >=18.12.0 >=18.12.0

@rsbuild/core >=16.10.0 >=18.12.0

Miscellaneous Updates
- Stabilized LazyCompilation feature—experiments.lazyCompilation is now available at the top level of Rspack's config.
- Deprecating experiments.topLevelAwait—setting it to false will now show a deprecation warning. This feature will be enabled by default and the config option removed in the next major release.

Release notes

Highlights 💡

Reduced install size ⚡️

In Rspack v1.4.9, we focused on optimizing our Rust dependencies and build flags. This effort has resulted in significant reductions to Rspack's install size across all platforms. We continue to work on further size optimizations and expect additional improvements in future releases.

Platform	Rspack 1.4.8	Rspack 1.4.9	Diff
@rspack/binding-linux-x64-gnu	59.4MB	51.3MB	8.1MB
@rspack/binding-darwin-arm64	46.1MB	43.2MB	2.9MB

Highlights

🚀 Rustify browserslist

Rspack now uses browserslist_rs instead of the browserslist npm package to parse browserslist query, which can make browserslist query parsing faster and improve consistency in SWC and lightningcss:
- Parsing default target is 5.5x faster than before.
- Removed caniuse-lite dependency, reduced 2.15MB install size.
See https://github.com/web-infra-dev/rspack/pull/10520 for more details.

Highlights 💡

Exposing SWC JS API

Rspack now experimentally exposes some SWC JavaScript APIs via rspack.experiments.swc. This allows you to call SWC methods like transform or minify without installing the additional @swc/core package.

See SWC API for more details.

Highlights

🚀 Support running JavaScript loader in parallel

Added a way to run JavaScript loader in parallel driven by worker_threads, using the max thread available on the OS.

This feature is still experimental. To enable parallelism, set Rule.use.parallel = true and experiments.parallelLoader = true:
```
module.exports = {
  module: {
    rules: [
      {
          test: /\.less$/,
          use: [
             {
                loader: "less-loader",
+               parallel: true,
                options: { ... }
             }
          ]
          type: "css"
      }
    ]
  },
  experiments: {
      css: true,
+     parallelLoader: true
  }
}
```
In big projects like 100x antd.less, we got 2.26x performance boost. (Tested on Apple M2 Max, 64G)

Highlights 💡

Introduce lazy compilation middleware

In the past, lazy compilation required starting a separate server to handle special requests which caused port, server config and proxy inconsistency, now its core capability is encapsulated as an express style middleware.

Developers only need a few lines of code to embed lazy compilation ability into their custom development server, solving the configuration inconsistent problem of multiple service instances. Users of @rspack/cli can use it without any changes, custom dev server users can easily access it through a middleware, check the following example, you can also see more detail in our official docs.
```
import { experiments, rspack } from '@rspack/core';
import config from './rspack.config.mjs';
import DevServer from 'webpack-dev-server';

const compiler = rspack(config);

const middleware = experiments.lazyCompilationMiddleware(
  compiler,
  { 
    entries: true, // lazy compile entries
    imports: true, // lazy compile dynamic imports
    ...config.experiments?.lazyCompilation
  }
);

const server = new DevServer(compiler, {
  port: 3000,
  setupMiddlewares(other) {
    return [middleware, ...other];
  },
});

server.start();
```
CircularDependencyRspackPlugin

We added a built-in plugin CircularDependencyRspackPlugin to Rspack to detect circular dependencies between runtime modules. Since the plugin is based on Rust, it is directly integrated with the Rspack module graph, avoiding expensive copying and serialization costs. The plugin traverses the module graph of each entry once to find all circular references, rather than checking modules individually, which means that the performance of the plugin is better.

Usage reference:
```
import { rspack } from '@rspack/core';

const config = {
  plugins: [
    new rspack.CircularDependencyRspackPlugin({
      failOnError: true,
    })
  ]
}
```

Highlights 💡

Support for the extends option

The rspack.config.js now supports an extends option, which is used to extend configurations from other files or packages. This allows you to create a base configuration and extend it for different environments or use cases.

Example usage:
```
export default {
  extends: './base.rspack.config.mjs',
  // Override or add to the base configuration
  output: {
    filename: '[name].bundle.js',
  },
};
```
