Nuxt 4.5 Adds Experimental SSR Streaming, Vite 8, and Rspack Builder
Nuxt 4.5 upgrades the framework to Vite 8 and introduces a new Rspack 2-based builder. It also adds experimental SSR streaming to improve time to first byte, along with a stable error code system and new composables for developers.

eslint-rspack-plugin 5.0.0 Released as Pure ESM
eslint-rspack-plugin 5.0.0 has been released as a pure ESM package, removing its CommonJS build to match the Rstack ecosystem. The plugin still embeds ESLint into the build process, but users may see longer build times and may want to use separate lint commands for better efficiency.

Rspack 2.0 Adds ESM Core and Faster Builds
Rspack, the ByteDance-backed JavaScript bundler, has released version 2.0 with a pure ESM core, leaner dependencies, and improved static analysis.

Business▼ Cooling
For BD, the Rspack story should be framed more cautiously: it is a sign of ecosystem interest, not proof that the market is ready to buy at scale. Conversations should center on controlled trials and specific integration needs rather than broad commitments.
Developers→ Steady
Rspack is still worth tracking, but the move from Trial to Assess signals it is not yet a default choice for moving an entire project over. For developers, the practical shift is to try it in a narrow scope, measure build time and compatibility, and only then decide whether to expand use.
Product▼ Cooling
For PMs, Rspack should be treated as an option to consider, not a primary selling point for the technical plan. The demotion from Trial to Assess means expectations should be lower, with small pilots and clear benefit criteria preferred before committing to a roadmap.
Testers / QA→ Steady
For test, the main change is to scrutinize build and SSR flows more carefully when Rspack appears in the stack, rather than assuming it is equivalent to more established options. The focus shifts toward compatibility and regression testing in areas that depend on the bundler/builder.
