web-infra-dev/rspack v1.0.0-beta.0 on GitHub

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(),
    ],
  },
};
