China Dev Radar #001: Rspack, OceanBase and Rsbuild
This week: Rspack's 2.3 beta changes JavaScript parsing and build diagnostics, OceanBase improves database operations, and Rsbuild adds new development workflows. Plus an earlier engineering deep dive from Meituan, explicitly marked as a research highlight.
Featured Developments
01
Rspack 2.3 Beta Introduces SWC Next Parsing and Memory Diagnostics
Originally published
What changed
Rspack 2.3 beta adopts SWC Next for JavaScript parsing, introduces content-aware loader filtering, improves code splitting and adds tools to inspect memory retained during builds and hot updates. The beta.1 follow-up renames the new loader option from filter.code to codeFilter; this is a prerelease, and performance benefits require workload-specific verification.

OceanBase 4.2.5 CE BP8 Improves Backup Security and Hot-Row Processing
Originally published
What changed
OceanBase 4.2.5 CE BP8 supports rotating backup/archive access credentials without changing the destination, adds optional GROUP_COMMIT hot-row update aggregation, improves MySQL-mode asynchronous stored procedures and increases CDC commit timestamp precision. Operators should check compatibility and documented upgrade restrictions.
Why it matters
The release addresses production concerns such as credential rotation, write contention and downstream change-data processing. Hot-row optimization is opt-in and should be tested on representative workloads.

Also Worth Knowing
03
Rsbuild 2.2.14 Adds TanStack Start Scaffolding
Originally published
The stable Rsbuild 2.2.14 release adds TanStack Start scaffolding for React and Solid and fixes environment-variable behavior, PostCSS discovery, development-server issues and public asset handling.
Why it matters
A practical update for developers starting or maintaining Rsbuild applications.

04
Rsbuild 2.3 Beta Adds Lynx Templates and Preview Lifecycle Support
Originally published
Rsbuild 2.3 beta adds Lynx scaffolding, updated TypeScript 7 templates, configurable size reporting and an onClosePreviewServer hook. It also upgrades to the Rspack 2.3 beta, so developers should treat this as a prerelease requiring compatibility testing.
Why it matters
This is a separate Rsbuild prerelease from the stable 2.2.14 release; its shared Rspack dependency is disclosed to avoid presenting the same underlying work twice.

Research Desk: Meituan's Small-Language-Model Inference Architecture
Originally published
Originally published October 15 (before this week's window), Meituan's technical article describes bounded-generation SLM inference using static execution DAGs, AOTInductor compilation, packed prefill, request-local KV sharing and selective FP8. The article's performance claims are publisher-reported, not independently reproduced.
Why it matters
An earlier but transferable example of adapting model serving to bounded workloads rather than applying a general-purpose inference engine unchanged.
Why it matters
Developers testing the next Rspack release can evaluate loader execution controls, memory debugging and parser compatibility. Review the beta.1 configuration rename before upgrading.
