Rspack 2.2 Lands 30+ Speed Boosts, pnpm 12 Goes Rust-Stable, and Solid 2.0 RC Bakes Async into Reactivity

🌰 Lizi Frontend Tech Weekly Issue 144 (2026.08.24 - 2026.08.30): Browse the latest frontend news of the week, learn excellent articles from home and abroad, and keep our curiosity about the frontend.

📰 Tech News

  1. Rspack 2.2: Rspack 2.2 has been released. Updates include: over 30 performance optimizations, such as shorter build times, improved HMR, and shorter module IDs; new features include import.meta improvements, support for Browserslist Baseline, and more platforms.

  2. pnpm 12: pnpm 12 has been released. The Rust rewrite is now officially stable. All commands, parameters, and the lockfile format from v11 are largely carried over, with only minor changes. The global Node version will also follow the version locked by the project. Note: npm's latest tag still points to pnpm 11; you need to run pnpm self‑update next‑12 to complete the upgrade.

  3. Solid 2.0 RC: Solid 2.0 RC has been released. Asynchrony is now built into the reactive dependency graph, so async data can flow directly through ordinary memos (memoized computations). createResource, batch, and startTransition have all been removed. SolidStart is officially retired; its capabilities are now enabled via the start: true flag on a Vite plugin, and the current API is frozen.

  4. Node.js 26.8.0: Node.js 26.8.0 (the latest Current release) has been released. This update adds several capabilities: Node.js can now read and write ZIP archives without third-party dependencies. Additionally, the Node REPL now supports basic syntax highlighting. v26.8.1 was also released this week, fixing an issue with an abnormal version string.

📒 Tech Articles

  1. ESM and CommonJS: What import and require Actually Do: ESM and CommonJS: How import and require really work — The two appear to be the same kind of operation, but the author explains: ESM's import always binds to the variable reference on the exporter's side, whereas a destructured require() only gets a copy. This difference has practical consequences in circular dependencies and published third-party packages.

  2. WebSockets vs. SSE should be about ordering and correctness: The choice between WebSocket and SSE should center on message ordering and correctness — The author dives deep into the differences between WebSocket and Server-Sent Events.

  3. One line of new CSS kills 20 lines of JavaScript: The article rounds up 6 pure CSS new features that gained full mainstream browser support in 2026 but are still seriously underestimated by a large number of domestic frontend developers.

🔧 Dev Tools

  1. Mobile View: A Chrome browser extension that can test up to 5 views simultaneously, covering iPhones, Android devices, and tablets; supports scroll sync, view rotation/zoom, light/dark themes, and more.
