Rolldown Consolidates Vite: Unified Rust Bundler Reshapes Development and Production Builds

Vite 8's transition from dual bundlers to a single Rust-based engine delivers 10-30x faster production builds while eliminating the dev/prod inconsistencies that previously hid bugs in shipping code. However, this architectural consolidation brings significant breaking changes—projects relying on esbuild or Rollup-specific plugins will require careful migration and reconfiguration. This shift signals a broader industry trend where performance-critical infrastructure is moving toward compiled languages, making this a critical moment for teams to reassess their build toolchain strategy.
