我们很高兴地宣布，Rspack 2.2 已发布！

如果你正在面对建立速度慢、HMR 失效、产物体积膨胀、Solid 迁移困难或多网站兼容性问题，那么这一次的更新将为你带来实质性的改进。

性能调整

建立速度提高

在实际基准测试中，生产建立时间从XX ms降至YY ms提高约% 。按理说，主要流程均被重新设计，极大减少了 I/O 与 CPU 占用。

CopyRspackPlugin 加速

复制大量文件时CopyRspackPlugin 的性能提高约N~M 倍让文件拷贝不再成为瓶颈。话说回来，

Wasm 产物体积调整

Wasm 包体积从X MB降至Y MB节省了约Z MB

并行编译 SWC Wasm 插件

通过并行加载 SWC Wasm 插件，插件加载时间缩短了约%

CSS 解析速度提高

Lighter HMR 请求^{*1†††††††††††*}

Mistake: When you modify only JavaScript。previous Rspack would still request entire CSS bundle during HMR – a wasteful HTTP call that grew expensive as stylesheets got larger.

This version determines CSS changes at build time and sends requests only when necessary,eliminating extra round-trips and keeping JavaScript HMR fast regardless of stylesheet size.

Mega Fix for

The plugin’s short-lived CSS glitch is now fixed;不过，no more flicker during updates.

Easier Module & Chunk ID Management ^{*1‡‡‡‡‡‡‡‡‡‡‡*}

The new 'compat-hashed' strategy produces shorter deterministic IDs than old 'deterministic'。shrinking bundle size without sacrificing stability or runtime lookup speed.

// rspack.config.js
export default {
optimization: {
chunkIds: 'compat-hashed',moduleIds: 'compat-hashed',},};

Nueva Funcionalidad: import.meta Mejorado y más...

`import.meta` Enhancements

You can now access Rspack-specific variables in ESM modules via `,replacing old CommonJS-style variable and aligning 娱乐ter with ESM semantics.

__webpack_public_path__ = '/assets/';import.meta.rspackPublicPath = '/assets/';
按理说，

• Add support for 's new option:
"
• You can set it false to ignore case in glob matching:

  const modules = import.meta.glob;

• This is perfect for teams working on cross-platform codebases where file names may differ in casing.
