The adapter was built together with the Rsbuild and Rspack teams and covers the full Start feature set, including React and Solid apps, Server Functions, SSR, streaming SSR, HMR, import protection, and React Server Components. Teams migrating from Webpack setups can adopt Start on Rsbuild without also switching build tools, and one large company is already doing so across several apps. The addition also clarified boundaries between shared Start build logic and build-tool-specific adapter code. ## Full article daily.dev links to this article rather than hosting it.

Yes, TanStack Start now supports Rsbuild 2 as a fully supported build-tool path alongside Vite. The adapter was built with the Rsbuild and Rspack teams and covers React and Solid apps, Server Functions, SSR, streaming SSR, HMR, import protection, and React Server Components for React apps. It is configured through the tanstackStart() plugin from @tanstack/react-start/plugin/rsbuild. _Teams weighing Vite versus Rsbuild for a Start app can track framework tooling shifts like this on daily.dev._ ### Can I migrate an existing Webpack app to TanStack Start without switching build tools? Yes, moving to TanStack Start on Rsbuild lets a team keep a build setup closer to Webpack instead of changing framework and build tool simultaneously, since Rsbuild is built on Rspack and feels familiar to Webpack users. One large company is already using this path to move several apps from Webpack to Start on Rsbuild. _Teams planning a Webpack-to-Start migration can follow build-tooling changes like this on daily.dev._ ## Similar posts on daily.dev - [TanStack Start - A New Meta Framework Powered By React Or SolidJS](https://daily.dev/posts/tanstack-start---a-new-meta-framework-powered-by-react-or-solidjs-kqfr1cdvm) · InfoQ · 40 upvotes · 2 comments - [TanStack Start gets RSC](https://daily.dev/posts/tanstack-start-gets-rsc-mijrowtfp) · Bytes by ui.dev · 60 upvotes · 5 comments --- Tags: [#react](https://daily.dev/tags/react), [#vite](https://daily.dev/tags/vite) [View this post on daily.dev](https://daily.dev/posts/tanstack-start-adds-first-class-rsbuild-support-j8naqblez)
