v1.0.0-beta.1

Highlights 💡

Import Attributes

Rspack now supports Import Attributes by defaults:

import json from "./foo.json" with { type: "json" };

import("foo.json", { with: { type: "json" } });

PR: #7333

Layers

Rspack now supports module and chunk layers. This feature can be used by frameworks like Rsnext (The Rspack-based Next.js) to implement React Server Components.

• Example: build modern and legacy bundles at the same time:

export default {
  entry: {
    index: {
      import: './src/index.js',
      layer: 'modern',
    },
    'index-legacy': {
      import: './src/index.js',
      layer: 'legacy',
    },
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        issuerLayer: 'modern',
        use: [
          {
            loader: 'builtin:swc-loader',
            options: {
              env: {
                targets: 'Chrome >= 87',
              },
            },
          },
        ],
      },
      {
        test: /\.js$/,
        issuerLayer: 'legacy',
        use: [
          {
            loader: 'builtin:swc-loader',
            options: {
              env: {
                targets: 'ie >= 11',
              },
            },
          },
        ],
      },
    ],
  },
  experiments: {
    layers: true,
  },
};

• Example: Customize rules and resolve options for RSC modules

export default {
  module: {
    rules: [
      // set `layer` for some modules
      {
        test: /rsc-modules/,
        layer: 'rsc',
      },
      // set resolve options for specified layer
      {
        issuerLayer: 'rsc',
        resolve: {
          conditionNames: ['react-server', '...'],
        },
      },
      {
        // set loaders for specified layer
        oneOf: [
          {
            issuerLayer: 'rsc',
            test: /\.tsx?$/,
            use: ['some-rsc-loader'],
          },
          {
            test: /\.tsx?$/,
            use: ['some-normal-loader'],
          },
        ],
      },
    ],
  },
  experiments: {
    layers: true,
  },
};

v1.0.0-beta.0

Performance Improvements ⚡

In version 1.0.0-beta.0 we have made a number of performance optimizations, which together add up to significant performance gains. According to benchmark data, Rspack's dev startup is 4.7% faster, and its prod build is 11% faster.

Detailed changes:

• perf: reduce allocation for Stats by @h-a-n-a in #7124
• perf: reduce allocation for parsing by @h-a-n-a in #7219
• perf: use Set as Queue to solve the duplication by @JSerFeng in #7233
• perf: reduce allocation for ModuleRule matching by @h-a-n-a in #7249
• perf: reduce large pre-allocations for JavascriptParser::new by @h-a-n-a in #7286
• perf: faster hasher for Ukeys by @ahabhgk in #7287
• perf: a bunch of small improvement for ConcatenatedModule by @CPunisher in #7257
• perf: reduce allocation for adding dependencies by @h-a-n-a in #7301

Breaking Changes 🛠

Upgraded to latest SWC

@rspack/core now depends on swc_core v0.99 (previously v0.96).

If your project is using the SWC Wasm plugin, this will be a breaking change, and you will need to upgrade the SWC Wasm plugin to the latest version.

PR: #7292

Upgraded to webpack-dev-server v5

@rspack/cli now depends on webpack-dev-server v5 (previously v4).

If you are using @rspack/cli, please be aware of the following breaking changes:

• The minimum supported Node.js version of webpack-dev-server@5 is 18.12.0.
• The devServer configuration of Rspack include several breaking changes. Please refer to the webpack-dev-server v5 migration guide for more details.

PR: #7130

Deprecated @rspack/plugin-minify

rspack/plugin-minify has been deprecated as it was a temporary package to support Terser.

Now Rspack has full support for terser-webpack-plugin. If you need to use Terser as the minimizer, we recommend using terser-webpack-plugin instead of @rspack/plugin-minify:

// rspack.config.js
- const MinifyPlugin = require('@rspack/plugin-minify');
+ const TerserPlugin = require('terser-webpack-plugin');

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [
-    new MinifyPlugin({ minifier: 'terser' }),
+    new TerserPlugin(),
    ],
  },
};

Full Changelog: v0.7.4...v0.7.5

v0.7.4

What's Changed

Highlights

LightningCSS minimizer

In v0.7.4 Rspack provides a new CSS minimizer which uses Lightning CSS under the hood, for now you can enable it by optimization.minimizer, and in Rspack v1.0, it will be enabled by default.

And here are two very useful features powered by the new LightningCSS minimizer:

• removeUnusedLocalIdents: during minification, it removes the CSS declarations corresponding to the unused-symbols. This allows Rspack to work with CSS modules' tree shaking to remove unused CSS declarations corresponding to exports (previously, it would only remove the JS exports).
• browserslist: with this options minification will also performs downgrading. If the postcss-loader was previously used only for downgrading, it can be removed.

Checkout our docs for more details.

Compatible with worker-loader

In v0.7.4 Rspack is compatible with worker-loader, which is usually used by some older projects, so this is provided only as a temporary solution to facilitate these older projects migration to Rspack, checkout our docs for more details.
